Do you centrifuge sodium heparin tubes?       In clinical biochemical testing, most analysis relies on serum or plasma samples, but the whole blood is extracted from the human body, making it difficult and time-consuming to prepare complete serum or plasma samples. In order to solve this problem, reagents such as EDTA potassium salt, heparin sodium, and serum separation gel have emerged in the domestic market to help improve efficiency. Under the treatment of these reagents, blood samples can also be quickly prepared into stable specimens by centrifugation, thus achieving detection purposes. The use of heparin sodium test tubes is relatively common, but there is also great controversy. Some people believe that it does not need centrifugation, while others believe that it should be centrifuged. So, does it really need to be centrifuged? Below is a specific analysis for everyone.   Bottled heparin sodium       The anticoagulant effect of heparin sodium in blood vessels       Because it is a natural anticoagulant substance extracted from animal liver organs, it can bind with antithrombin 3 to cause structural changes. After its activity is activated, it binds to coagulation factors, thereby inhibiting the action of coagulation factors, leading to weakened thrombin reaction and prolonged coagulation time. In blood collection, it plays a role in preventing coagulation of blood samples, which can provide convenience for the biochemical testing items that need to be carried out.       Is the heparin sodium test tube centrifuged       In blood collection, it plays a role in preventing blood clotting, but cannot extract the required serum or plasma samples, so centrifugation is required. Only by centrifugation can the blood sample be completely separated, and then the centrifuged sample is used for testing to obtain accurate results. There are many cellular components in whole blood, and there are also differences in the testing items. If centrifugation is not carried out, it may lead to difficulties in conducting experiments, such as the blockage of analytical instruments due to the presence of fibrin in serum.       Items for heparin sodium test tube testing       1. Routine blood testing: Due to its strong physicochemical properties and physiological inertness, it does not affect blood composition and is less prone to hemolysis on red blood cells, so it is often used in routine sample analysis.       2. Liver function test: It can prevent blood clotting, so it is suitable for checking liver and kidney function, such as detecting fatty liver, hepatitis, etc.       3. Blood gas and erythrocyte sedimentation rate detection: Due to its interference with coagulation, it can have the effect of antithrombin. After the coagulation time of the sample is extended, it can be applied to blood gas analysis and erythrocyte sedimentation rate examination.       As a raw material manufacturer for blood collection additives, Desheng produces all products with analytical purity and stable performance. If you have high requirements for blood samples and want to quickly centrifuge, you can choose our serum separation gel to complete.

Effect, dosage, and preservation method of dipotassium edta anticoagulant       Ethylenediaminetetraacetic acid dipotassium CAS is 25102-12-9, which is a recommended treatment reagent by the International Committee on Hematology. It not only has good anticoagulant effects, but also has little impact on blood cell composition, ensuring that the morphology of red blood cells, white blood cells, and platelets does not change, and has strong stability. Based on these obvious advantages, it has become an indispensable processing reagent in clinical medicine. Below, we will introduce it in detail.       1、 The effect of potassium ethylenediaminetetraacetic acid anticoagulant   As a calcium chelating agent, due to the presence of calcium ions in the blood, it can chelate with calcium ions. This decrease in calcium ion content will prevent endogenous or exogenous coagulation processes, thereby achieving the goal of anti blood coagulation. It is suitable for various biochemical tests. But precisely because of its anticoagulant effect, it cannot be used for the determination of metal substances in plasma and coagulation experiments, otherwise the accuracy of the experimental results cannot be guaranteed.   EDTA K2 Powder       2、 Concentration addition of potassium ethylenediaminetetraacetic acid anticoagulant       Although blood collection vessels containing potassium ethylenediaminetetraacetate are currently widely used, the amount of concentration added remains a problem. It is generally recommended to collect 0.5-2ml of blood in test tubes, but in the actual blood collection process in hospitals, it may sometimes exceed the standard blood collection range, which may lead to an imbalance in the ratio of blood samples to potassium ethylenediamine tetraacetate anticoagulant, leading to slight coagulation of the sample, instrument blockage, or inaccurate analysis results. Therefore, in response to this phenomenon, relevant researchers have provided the most appropriate standard concentration range of potassium ethylenediaminetetraacetate at 2.24mg/mL.       3、 Preservation of potassium ethylenediaminetetraacetic acid anticoagulant       The finished product of potassium ethylenediaminetetraacetic acid sold as powder is easily affected by moisture when dissolved in water, so its storage method and quality are closely related. If it is necessary to prepare it into a solution, be sure to immediately remove and seal it, and do not place it in an excessively humid environment. If the solution is in a prepared state, it needs to be stored in a high-density glass bottle to ensure that the storage device is free of impurities, reduce the possibility of reaction between potassium ethylenediaminetetraacetate and other substances, and pay attention to the surrounding environment being dry and the temperature not being too high.       As an advantageous manufacturer of potassium ethylenediaminetetraacetic acid anticoagulant, Desheng has clear specifications for its key indicators such as pH value, solubility, molecular weight, and stable quality, which can be used by customers to complete different experiments. At the same time, there are a large number of spot goods for sale in the warehouse, and there is no shortage of goods, so there is no worry about use.

what is heparin sodium used for       When conducting blood sampling tests in hospitals, test tubes containing heparin sodium are often used. Due to their anticoagulant properties, blood samples can be specially processed, and can provide effective reference value for disease diagnosis and pathological analysis. Therefore, they are often used in routine biochemical testing projects. Insiders can tell at a glance what heparin sodium is used for, but laypeople may not have a deep understanding of it. Therefore, let me give you a specific scientific popularization of what heparin sodium is used for?       The principle of heparin sodium       In fact, to know exactly what it is used for, one must know its mechanism of action from the source. Due to its unique properties, it can fundamentally inhibit the activity of coagulation factors by binding to them, thereby inhibiting the formation of thrombin, prolonging the process of transforming soluble fibrinogen into insoluble fibrinogen, and fully inhibiting platelet aggregation to achieve anticoagulant effects.   Bottled heparin sodium       The effect of heparin sodium       According to the wide range of application fields, it can be classified and applied in various aspects:       1. Blood collection anticoagulant       Based on its mechanism, it can be known that it has the effect of preventing blood clotting, and because it is of analytical purity, it is often added to blood collection vessels to have an anticoagulant effect on blood samples. Due to its good anticoagulant effect and effective guarantee of the stability of serum and plasma components, it has been highly valued in clinical practice, so its appearance is mostly in the form of blood collection additives.       2. Medicinal heparin sodium       This is also used in drugs based on the principle of anticoagulation, but its production requirements are very strict, and there are few manufacturers that can meet the standards. Generally, it is made into drugs that can effectively prevent large coagulation diseases such as thrombosis and myocardial infarction by taking or injecting them into the human body. At the same time, it can also be used as a drug for hemodialysis or thrombolytic therapy to reduce the possibility of complications.       3. Daily chemical heparin sodium       It is mainly used in cosmetics or skin care products, such as nutrition cream, eye cream, acne removal and other products, which can significantly improve the Vascular permeability of the skin, while improving the blood circulation of the skin, improving local circulation, ensuring that the skin can obtain nutrients and promote the excretion of metabolites.       According to the properties of heparin sodium, it can be added to blood vessels, made into drugs, or added to cosmetics. It has many uses, so the quality requirements for heparin sodium raw materials are very strict. As a manufacturer of heparin sodium raw materials, Desheng can provide analytical grade heparin sodium for anticoagulant use in blood collection.

heparin sodium classification       Heparin, as a naturally occurring substance in animal liver, has been found to have anticoagulant effects. Therefore, many manufacturers have prepared heparin sodium or heparin lithium raw materials based on it for use in vacuum tubes. But they don't just have one function, they can be applied to different aspects through different categories, and their categories and prices also vary. Many people increase their purchasing costs because they don't know the classification, which sometimes brings a lot of trouble for experiments. So in response to this situation, let's take heparin sodium as an example and introduce the classification in detail. Later on, we can also differentiate and purchase.   Bottled heparin sodium       1、 Analytical grade heparin sodium       The main source of its extraction is pig small intestine mucosa, but the production process is fine, with strict numerical requirements. The finished product is a white powder, easy to dissolve in water, with an average molecular weight of around 15000 and a potency between 150IU-180IU. It is formulated as a solvent and added to vacuum blood collection vessels to have an anticoagulant effect on blood.       2、 Low molecular weight heparin sodium       It is mainly used for medical injection into the human body, and its production requirements are generally stricter than other types of heparin sodium, and its price is expensive. It can be used to treat large diseases such as thrombosis in the human body. Although it is also composed of a mixture of polysaccharide chains, its average molecular weight is between 4000 and 5000, which is much lower than the analysis of pure heparin sodium. It also has strong anticoagulant effects and has fewer complications in clinical treatment of thrombosis.       3、 Cosmetic grade heparin sodium       This is a raw material in cosmetics, which is usually added to the skin care products of redness, swelling and acne gel. The addition amount is about 0.6%, which can use its anticoagulation, thrombosis and blood viscosity reduction effects to improve the skin permeability, improve the local skin blood circulation, and is conducive to the nutrition supplement of the skin, which has a good maintenance effect.       There are roughly three categories of heparin sodium mentioned above. There are differences in the production processes and requirements of these three types, and their prices also vary. Please choose according to your own usage. As a professional manufacturer of heparin sodium, Desheng sells heparin sodium products that are analytical pure for external use and cannot be directly used in the human body. When purchasing, users can express their purpose clearly, which is convenient for customer service to provide accurate answers.

Heparin sodium, as an anticoagulant reagent, is usually added to vacuum tubes for medical staff to use. Currently, the most widely sourced source of heparin sodium on the market is extracted from the intestinal mucosa of healthy pigs. However, due to the large amount of impurities and bacteria in the heparin sodium directly extracted from pig mucosa, it requires manual separation and preparation to obtain high-quality heparin sodium raw materials.   heparin sodium   China has a vast territory, a large-scale animal husbandry industry, and abundant pig resources, making it a major country in extracting heparin. Nowadays, most domestic manufacturers also extract crude products from pig intestines and make them into high-quality products for sale. Although the extraction methods are unified, there are still differences in their respective preparation methods. Below, we will discuss in detail how to prepare heparin sodium extracted from pig mucosa?   Steps for extracting heparin from live pigs   1. Bowel washing: Clean the feces inside the intestine, and then soak the pig intestines filled with water in water for a day. If the temperature is too high in summer, add ice to the soaked water.   2. Intestinal scraping: Generally, a scraping machine is used to operate. The soaked pig intestines are placed in the scraping machine, and the mucosal surface of the intestine is scraped. Then, the casing is scraped to obtain a complete and undamaged casing.   3. Irrigation: Rinse the scraped casing with clean water, remove any impurities left during the scraping process, and then check if the casing is damaged or spoiled.   4. Salt pickling: Spread the casing evenly, fully apply the specialized salt required for production to each part, marinate for one day, repeat the operation the next day, then put it into a tank to drain the salt water, and then refrigerate at low temperature to prevent spoilage.   Extraction method of crude heparin sodium   1. Resin treatment: Pour a certain amount of heparin sodium specific resin into the cylinder, wash off impurities adhered to the surface of heparin sodium with water, and then remove water before pouring it into alcohol and letting it stand overnight. Then remove the alcohol and pour it into 40 degree hot water to wash away the remaining alcohol smell in the cylinder. Soak it in a calculated hydrochloric acid solution and stir repeatedly during this process.   2. Salt hydrolysis: Put the scraped casing into the mixing tube, add water and specialized salt for casing processing, stir thoroughly, and then add alkaline substances to adjust the pH value, heat up and filter.   3. Adsorption: Pour the pre processed heparin sodium resin into the adsorption tank and stir, accurately control the concentration of the adsorbed solution, and use a filter screen to remove the heparin sodium resin.   4. Washing: Wash with professional processed salt from the casing, stir the heparin sodium resin twice at intervals, pour the washing solution, and wash away any interfering substances adsorbed in the resin.   5. Precipitation drying: After washing, add alcohol and stir, cover and seal, and then place in a low-temperature refrigeration room to precipitate for 24 hours. Collect the paste heparin, and then use the precipitate to load a plate and dry it in a 60 degree drying oven for 3 hours to obtain the crude heparin sodium.   Product packaging   After the above steps, crude heparin sodium can be obtained, and on top of it, refined heparin sodium can be prepared for use. As a professional manufacturer of heparin sodium, Desheng takes every step to extract heparin from pig intestines and manually prepare it, providing customers with on-site inspection opportunities.

Does heparin affect sodium levels？       As a natural anticoagulant reagent, heparin usually contains two types: heparin sodium and heparin lithium. Normally, the intake and excretion of sodium in the human body should be balanced. However, in clinical practice, medical staff using heparin tubes for electrolyte analysis may find that sodium levels are higher than normal reference values. Why is this? Some people suggest that the addition of heparin leads to an increase in sodium levels. Is this really the case? Based on this question, let's carefully analyze it for everyone.       Based on the questions raised, Desheng also conducted analysis and research on this, comparing blood samples collected using test tubes with and without heparin to analyze whether the extracted detection components have been affected. The experimental results showed that heparin anticoagulation had a significant effect on blood potassium, but had no significant effect on sodium levels. From the analysis, it can be seen that heparin substances are prone to react with potassium ions contained in the blood sample to generate heparin potassium, interfering with the determination of potassium by ion selective electrodes, resulting in a low potassium ion content in the analysis results.   Bottled heparin lithium       In addition, from the serum samples, it can be seen that due to the destruction of platelets in the blood, they cannot aggregate and release potassium ions, resulting in a serum concentration greater than that of plasma, and the degree of enhancement is proportional to the number of platelets. During the experiment, due to the fact that platelets have been destroyed and cannot accurately reflect the true level of potassium in the body, the use of heparin tube detection will directly affect the determination of potassium ions, without affecting sodium levels.       From the source of heparin, it can be inferred that it is used as a natural anticoagulant reagent and its function in contact with blood in test tubes is to prevent blood clotting. If it affects other components of the blood, it not only indicates poor quality of heparin, but also requires careful selection. However, in practical clinical applications, its use is widespread, especially in biochemical diagnosis, where heparin is used to ensure the accuracy of analysis results and improve efficiency. If it affects sodium levels, it is likely that clinical practice will use these types of test tubes with caution, rather than using them in large quantities.       As an experienced manufacturer of raw materials for blood collection reagents, Desheng has a wide range of product types, including serum separation gel, heparin lithium, heparin sodium, EDTA potassium salt, coagulant enhancer, silicifying agent, etc. These products are of analytical purity and have stable performance, which can be selected and used by blood collection manufacturers. And the separation adhesive products are supported by independently developed patented technology, ensuring that customers have no worries about using them.

Gel serum separation method and precautions       With the improvement of people's health awareness, blood testing has become more common, and most disease diagnoses also need to start from the patient's blood, using instrument and equipment data for comparison, in order to effectively help improve the disease diagnosis rate. To fully ensure the accuracy of the results, the first step is to do a good job in blood collection and separation, in order to obtain high-quality serum samples and improve overall detection efficiency.       1、 How to collect blood       In the early stage, the method of collecting blood in clinic was to use glass tubes without any additives, but there were many drawbacks, such as: long time storage, not obvious separation effect, which would affect the normal blood separation work, so later the appearance of separation gel slowly stopped using this method to collect blood.   Serum separating gel       2、 Gel serum separation method       The initial method of serum separation was the more common water bath centrifugation. Although the separated serum samples can be used for testing and analysis, if the storage time is extended, the serum will undergo changes, leading to inaccurate data. Such sample detection is of little significance. After the appearance of the separated gel, this method is no longer used.       The method of separating serum by gel mainly depends on gel. Because there are a lot of hydrogen bonds in the structure of separating gel, it can quickly and efficiently separate serum from blood clots according to specific gravity, viscosity, physiological inertia and other indicators. For stored serum samples, they can be stored for a long time without any changes or abnormal test results.       3、 Precautions for gel serum separation       It is worth mentioning that during serum separation, attention should be paid to the use and operation of gel tubes, of which the more important two points are to ensure the complete coagulation of blood and the control of centrifugation. The specific details are as follows:       1. After collecting the blood sample with gel tube, shake it slowly and evenly, then place it for half an hour, and centrifuge it on the machine after full coagulation.       2. The control time for centrifugation operation should be 10 minutes at a speed of 3500 to 4000. After centrifugation, it is also necessary to let it sit for a few minutes until the serum and blood clots are completely separated before using the instrument for detection.       Separation gel is very important in the process of extracting high-quality serum samples, and selecting a reliable separation gel supplier is the key factor. Desheng is a professional manufacturer of serum separation gel. It has never interrupted the research and development of separation gel for 18 years. After five generations of sophisticated production, it was able to provide customers with high-quality separation gel, which was highly praised.

Introduction to ethylenediaminetetraacetic acid dipotassium salt dihydrate       Due to the fact that medical staff analyze patients' conditions based on abnormalities in various blood indicators, blood sample testing has become one of the important and necessary procedures in clinical practice. The early collection and analysis of blood samples were all manually operated, and later gradually developed into fully automated operations. As a blood processing reagent, the application of ethylene diamine tetraacetic acid dipotassium salt dihydrate also promoted the development of automated blood testing.       1、 The Effect of Ethylenediaminetetraacetic Acid Dipotassium Salt Dihydrate       There is often a difference between ethylenediamine tetraacetic acid dipotassium salt and ethylenediamine tetraacetic acid dipotassium salt dihydrate in the market. As an anticoagulant reagent in blood collection, the advantage of dihydrate will be very obvious. Because it contains two water of crystallization, compared with the anhydrous dipotassium EDTA, it has weaker moisture absorption capacity, stronger stability, is not easily affected by moisture, and is conducive to storage and use.   EDTA dipotassium       2、 Anticoagulant principle of ethylenediaminetetraacetic acid dipotassium salt dihydrate        As a popular anticoagulant reagent, its demand is increasing. The principle of action is that it is an amino polycarboxylic acid that can be close to calcium in blood samples. When complexed with calcium, prothrombin cannot be converted into thrombin and has minimal impact on blood cell components, thus achieving anticoagulant purposes. Generally, 4 ℓ of ethylenediaminetetraacetic acid dipotassium salt dihydrate corresponds to 2 milliliters of anticoagulant blood, but it must be a dihydrate with a purity of over 99%, otherwise the test results may be inaccurate.        3、 Addition and use of ethylenediaminetetraacetic acid dipotassium salt dihydrate       Due to the powdery nature of the produced ethylenediaminetetraacetic acid dipotassium salt dihydrate, it needs to be prepared into a solution when added to a test tube. Deionized water is often used to dissolve and mix, and then the solution is sprayed onto the tube wall by machine or manual means for drying. Due to the retention of water in the tube wall, clinical blood collectors should quickly mix it upside down and make it fully contact with the blood in order to achieve the best anticoagulant effect.       As a professional manufacturer of blood vessel additives, Desheng has a complete range of product types, all of which are analytical grade. Additionally, the potassium salt of ethylenediaminetetraacetic acid has two properties of anhydrous and dihydrate as reagent raw materials, which can be chosen by customers themselves. At present, the domestic market has a high level of satisfaction with the use of blood collection additives produced by the company, which has been recognized by multiple customers.

Introduction to the Performance, Formulation, and Addition of Dipotassium Ethylenediaminetetraacetic Acid       Dipotassium ethylenediaminetetraacetate, as a commonly used reagent in clinical blood testing tubes, is suitable for various biochemical tests and provides effective value reference for clinical diagnosis, analysis of data, and treatment due to its ability to form stable complexes with calcium substances in blood samples, which can interfere with the coagulation process and prevent blood coagulation. Let's have a detailed discussion here.       1、 Performance of potassium ethylenediaminetetraacetic acid   Its appearance is white crystal powder, odorless, and soluble in water. As the finished product is in powder form, it is easy to absorb moisture, with a main content of over 99%. It is of analytical purity and can be prepared into a solution to be sprayed on the inner wall of the test tube when used. As it does not affect cellular components and can fully inhibit platelet aggregation, it is widely recognized in clinical use as a blood treatment reagent and is also recommended as an ideal anticoagulant reagent in the industry.      EDTA potassium powder       2、 Preparation of potassium ethylenediaminetetraacetic acid solution       Based on its performance, it can be determined that it is easily soluble in water, so the preparation process is also very simple. Prepare deionized water to dissolve to the required capacity. Due to the possibility of powder residue on the bottle mouth or inner wall of the instrument during the preparation process, in order to avoid excessive concentration or dilution of deionized water, the amount of potassium dioxide solution added to the test tube will be controlled. If it is necessary to increase the amount of potassium dioxide added, the preparation concentration can be increased first before considering whether to increase the spraying frequency. During this process, attention should be paid to formulating according to the test tube standard to avoid excessive concentration that may cause the experiment to fail.       3、 Addition amount of potassium ethylenediaminetetraacetic acid       According to industry standards, the addition amount is 1.5 to 2.2mg of potassium ethylenediaminetetraacetate per milliliter of blood. When preparing the reagent, the median value is 1.8mg/ml. Due to different experimental requirements, the addition amount can also be flexibly adjusted during use. Additionally, it should be noted that potassium ethylenediaminetetraacetic acid can be used in combination with sodium fluoride. When they are placed together in a test tube, the amount added may change, usually by adding 1.2-2.0 milligrams of potassium dioxide per milliliter of blood, and 2- 4 milligrams of sodium fluoride.       As the raw material supplier of blood collection tube additives, Desheng produces serum separation gel, EDTA potassium salt anticoagulant, accelerator, silicating agent and other products with stable performance and analytical purity. Adding them into the vacuum blood collection tube can effectively help experimental detection. If you are interested, please click on the website to inquire and purchase!

serum clot activator tube with gel separator       Previously, blood samples were collected and placed for a period of time to naturally coagulate before waiting for serum to precipitate. This not only took a long time, but also greatly affected the functionality of the analytical instrument. In order to rapidly promote the development of detection technology, it was developed to add serum clot activator and separation gel into the test tube. The combination of these two substances is also called serum separation gel coagulation promoting tube. Its appearance is the key to quality control in the blood collection process, and it also helps medical staff prepare high-quality serum samples, reducing the possibility of cross infection. So let's take you to a specific understanding below.       1、 Serum separation gel activation tube       In fact, this test tube is called blood coagulation promoting tube, which contains two substances: separating gel and coagulant. The coagulant is a kind of reagent developed in clinic to quickly promote blood coagulation. Generally, it is composed of silica powder, emulsifier, surfactant and other components, and then it is processed to obtain the powder. When it is used, it is prepared into a solution, sprayed on the inner wall of the test tube containing separation gel, and then placed in an oven for evaporation and drying. Although there are activators that can quickly coagulate blood, it is still necessary to observe whether the blood has completely coagulated before separation and extraction, otherwise it may lead to fibrin inclusion in the isolation layer and contamination of the serum sample.         2、 Activate the blood clotting time inside the tube       Although fully automated analytical instruments can detect thousands of samples per hour, the speed of separating serum samples in the laboratory cannot keep up, which directly affects the overall detection efficiency. The most important factor is the speed of blood coagulation, which is not only related to the material of the test tube, but also directly related to the temperature. Usually, coagulation factors can be quickly activated in glass test tubes, requiring a temperature condition between 23 and 25 degrees Celsius for 1 hour. However, plastic tubes have weak activation ability, and blood can only fully coagulate in 2-4 hours.       3、 Significance of gel activation tube for serum separation       Due to the fully automated operation of clinical laboratory centers, a large number of instruments are used during the blood collection process. If one step is wrong, it will pose a hidden danger to the experiment. This not only affects the collection of blood samples, but also makes it meaningless to separate serum. By using a separation gel activated tube, it can reduce waste items, complete collection and detection on the original tube at once, without the need for other instruments, and the steps are reduced, which has great significance for the safety and efficiency of current medical testing.       As a raw material supplier for blood vessel additives, Desheng has a complete range of product types and series, which can meet different experimental needs of customers, and has reliable quality and worry free use.

what is serum gel blood test for       As an indispensable reagent in clinical medical detection, serum gel can isolate serum and blood clot during blood test due to its stable performance, which generally appears in biochemical indicators, immunological tests, coagulation mechanism and other detection and analysis. Due to its convenient use in blood testing, simple and fast processing steps, and the ability to obtain high-quality serum samples, it has become one of the reagents that hospitals are passionate about using. Although serum gel has obvious advantages, many people still do not know what serum gel blood test is? In fact, to understand what serum gel blood test is, you need to first understand the relevant knowledge of serum gel. You can focus on the following three points:       1、 Key performance of serum gel        The key performance of serum gel is its specific gravity, viscosity and physiological inertia. The specific gravity determines whether it can turn over during the processing of blood samples to separate serum from blood clots. And viscosity represents whether it is convenient to add to the test tube and whether it will be affected by temperature during transportation. Physiological inertness represents whether it will interfere with blood components and whether its stability is strong enough. Based on these important properties, the addition of serum gel into the test tube will not affect the blood test, which is also an aspect that everyone must pay attention to when selecting serum gel.   Serum separation       2、 Dose of serum gel added to test tube       In terms of the dosage, the judgment standard is very intuitive. No matter what kind of blood collection tube is and what its diameter is, after the injection of serum gel, the thickness of gel should always be greater than or equal to 6mm. If this thickness is not reached, the isolation effect between serum and blood clot is likely to be poor. Even if the isolation can be achieved, the medical staff will not be able to distinguish whether there is serum gel in the test tube because of the insufficient amount of separation gel. However, sometimes it will be adjusted according to the actual situation. For example, 0.8g of serum gel will be used for test tubes with diameter ¢ 13, and 1g of gel will be used for test tubes with diameter ¢ 16, and then observe whether it reaches 6mm according to the added amount.      3、 Blood test with serum gel tube       As the detection object in clinical biochemical items, serum samples are tested with serum gel. In fact, gel is not directly used to complete blood detection, but only used as a blood processing reagent. Through special performance, blood samples are separated and high-quality serum or plasma samples are obtained before testing, which is an important step in the blood testing process. At the same time, because the treatment, analysis and preservation of blood samples are completed in one tube of serum gel, cross infection is directly avoided during blood test.       As a supplier of serum gel, Desheng has become a hot selling product in the domestic market because a professional team strictly controls the performance, which can ensure stable use of customers and no interference in experiments. Currently, we are continuously strengthening our cooperation with foreign clients. If you are interested, please click on the website to inquire and purchase!
