2023/10/07

Difference between edta and lithium heparin

In medical and biochemical experiments, anticoagulants are often used to prevent blood from clotting during collection and processing. The two commonly used anticoagulants are EDTA (ethylene diamine tetraacetic acid) and heparin lithium. Although they are all used to prevent coagulation, there are significant differences in their mechanisms of action, applicable scenarios, and methods of use. Let's take a look together.   1、 Different chemical structures   EDTA: Ethylenediaminetetraacetic acid (EDTA) is an organic molecule that typically exists in the form of a salt, such as EDTA dipotassium salt or tripotassium salt, usually prepared manually.   Heparin lithium: Heparin lithium is a polysaccharide compound with a complex chemical structure, usually extracted from animal mucosa (such as pig intestinal mucosa).   2、 Different mechanisms of action   EDTA: EDTA is a chelating agent that works by binding to metal ions in the blood to prevent the activation of coagulation factors. It can also effectively reduce the concentration of calcium ions, thereby inhibiting the activity of thrombin.   Heparin lithium: Its main mechanism of action is its binding with antithrombin III (AT - III). It enhances the activity of AT - III, inhibits the formation of prothrombin kinase, and further prevents blood clotting by interfering with the activity of thrombin.   3、 Different application scenarios   EDTA: EDTA is usually used in routine hematological examinations, especially in whole blood samples to prevent blood from clotting during collection and storage. It is suitable for blood routine and CRP examinations and plays an important role in cell counting and classification. It can maintain the morphology and structure of cells in the blood, allowing for accurate counting and analysis.   Heparin lithium: Heparin lithium is mainly used for clinical plasma analysis and is suitable for the determination of serum protein, liver and kidney function, etc. It is not suitable for blood routine tests, coagulation function, etc. In addition, heparin lithium is an ideal reagent for rapid separation of plasma and biochemical analysis.   4、 Different doses used   EDTA: The original state of EDTA potassium salt is powder, usually prepared as a solution and added to a test tube. The standard recommended dosage is 1.5-2.2mg EDTA per milliliter of blood, and if peripheral blood is collected, it is 18mg anticoagulant 1 milliliter of blood.   Heparin lithium: The dosage of heparin lithium solution added to the test tube is different from EDTA. Generally, the recommended standard in the industry is between 9.4IU-28IU per milliliter of blood, and peripheral blood anticoagulation is less than 14IU per milliliter of blood.   EDTA and heparin lithium are both important anticoagulants, but their chemical structure, mechanism of action, applicable scenarios, and dosage are different. Everyone should pay attention to distinguishing when using them.

lithium heparin and gel for plasma separation

Plasma separation is a common operation in clinical and laboratory medicine, which typically requires the use of a series of specially designed reagents and materials to ensure efficient plasma separation. Among them, the test tubes containing anticoagulant heparin lithium and separation gel are more common. So why use heparin lithium and separation gel test tubes instead of other types? This is inseparable from the role and significance of their combination.   1、 Key points of heparin lithium anticoagulation   Heparin lithium is an anticoagulant, belonging to one of the common types of heparin. Its main function in plasma separation tubes is to inhibit blood coagulation. Its anticoagulant effect is achieved by interfering with the interaction between thrombin and fibrinogen, which prevents the formation of fibrin and keeps the blood in its original state, making it easier to separate plasma. After collecting blood samples, the blood in the plasma separation tube will come into contact with heparin lithium, ensuring that the entire sample will not coagulate during the collection and separation process, and obtaining effective plasma.   2、 Effective separation of separation gel   Separation gel is another important component in the plasma separation process. It is usually located at the bottom of the plasma separation tube, and has precisely controlled density and viscosity. Under centrifugal operation, plasma will move up and float on the upper layer of the gel, while blood cells will deposit on the lower layer of the separation gel. This method not only ensures rapid separation of plasma, but also maintains the integrity of blood cells.   3、 Effect of heparin lithium for plasma separation on gel   The use of heparin lithium and separation gel ensures that blood samples can be separated efficiently and without pollution, making subsequent detection and analysis more accurate and reliable. At the same time, clinicians often need to carry out various blood tests, such as biochemical tests, disease screening, etc. The accuracy of plasma separation results also provides guarantee for clinical practice.   Heparin lithium and separation gel are indispensable components of the plasma separation tube and must be added. As reagents used in vacuum tubes, there are strict requirements on the quality of its raw materials.   As a raw material supplier for blood collection additives, Desheng has supplied to multiple blood collection enterprises with reliable and stable quality, high customer return rate, not only anticoagulants and separation gels, but also various types of products such as coagulants and silicides, with multiple selectivity and low prices.

lithium heparin tube used for which test

Heparin lithium tube is a commonly used device for blood collection and examination. As the test tube contains heparin lithium as an anticoagulant, it helps to prevent blood from clotting after collection. Not only does it provide convenience for medical staff during blood collection, but it also plays a crucial role in various types of examinations, ensuring the accuracy of the results. Now let's take a look at which tests are commonly used for heparin lithium tubes?   1、 Screening for liver diseases   After collecting blood samples, heparin lithium tubes can be used to check whether patients have liver diseases such as hepatitis, nephritis, or liver cancer. Although heparin lithium itself is not a test item, it can effectively prevent blood clotting and maintain the original state of the blood, which is very important for certain analytical instruments. Because only when blood is in a liquid state can accurate testing be conducted to obtain information about the patient's health status. And heparin lithium tubes can ensure the accuracy of the examination results, enabling medical staff to take timely measures to eliminate or prevent liver diseases.   2、 ESR and blood gas examination   The presence of heparin lithium makes it very useful in blood gas analysis and erythrocyte sedimentation rate tests. Due to its anticoagulant effect in the blood, it can interfere with the coagulation process and prolong the coagulation time of the specimen, which is very suitable for measuring blood gas parameters and erythrocyte sedimentation rate. However, it should be noted that heparin lithium tubes are not suitable for checking coagulation parameters, as they themselves can interfere with coagulation.   3、 Check electrolyte   Early electrolyte measurements used heparin sodium anticoagulant tubes, but it was later discovered that it may have an impact on certain test results. With the improvement of technology, heparin lithium tubes have gradually replaced heparin sodium tubes. This type of blood sample can be used for blood potassium testing and for taking upper plasma for examination after centrifugation and sedimentation. In addition, some hospitals also use 3ml of heparin lithium tubes to check the lead content of children, which is also helpful for screening for poisoning in children.   Lithium heparin tubes have played a role in multiple different types of examinations, ensuring that blood samples are collected in their original state during the analysis process, thereby obtaining accurate examination results. However, regardless of the project, the stability of the substance heparin lithium needs to be relied on.

solubility of heparin sodium

Heparin sodium, as a commonly used anticoagulant, is often added to blood collection vessels to ensure that blood remains in a liquid state during collection, transportation, and analysis, preventing coagulation. This additive with bioactive molecules requires a specific concentration of solution to ensure the anticoagulant effect in the test tube. However, as the original form of heparin sodium is powder, it needs to be prepared into a solution in advance before use, and there are certain requirements for its solubility. Therefore, let's take a look at the solubility of heparin sodium together.   Heparin sodium powder   Solubility of heparin sodium   The raw material of heparin sodium is powder, which has a certain solubility in water. Its solubility is often expressed as a percentage, in the form of w/v (mass/concentration). Normally, a 5% (W/V; 5g/100ml) heparin sodium solution is clear, which means that every 100 milliliters of solution contains 5 grams of heparin sodium. This concentration is sufficient to provide the required anticoagulant effect in the blood collection vessel, but sometimes it may be adjusted according to the needs of the enterprise.   Factors limiting the dissolution of heparin sodium   The dissolution of heparin sodium is sometimes influenced by factors such as temperature, pH value, and ion strength. Under normal room temperature conditions, powder is easily soluble, but under extreme conditions such as high or low temperatures, its solubility is limited. In addition, the pH value of heparin sodium in a 1% (W/V; 1g/100ml) pure water solution is between 6.0 and 8.0. If the dissolution pH value is too high, it will also cause changes.   Usage and dosage of heparin sodium in blood vessels   1. Solution preparation: In order to add heparin sodium to the blood collection vessel, it is first necessary to prepare a suitable concentration of heparin sodium solution. Usually, a ratio of 1:100 is used, which involves adding 1g of heparin sodium to 100g of deionized water, but this is not fixed and can be adjusted according to usage requirements.   2. Dosage selection: The dosage of heparin anticoagulation is usually determined based on the specific needs of experiments or blood collection. Generally speaking, the recommended range for heparin anticoagulation is 9.4-28IU/ml blood sample. According to the volume of the blood sample and the required degree of anticoagulation, an appropriate dosage of heparin sodium can be selected. For example, usually 20 IU of heparin anticoagulant 1 mL of blood sample is selected, or the dosage of 0.1 mg of heparin anticoagulant 1 mL of blood sample is prepared.   Heparin sodium is a commonly used additive in blood collection, and a thorough understanding of its solubility and dosage is of great help in ensuring experimental results. As an advantageous manufacturer of heparin sodium, Desheng can provide raw material powders with good solubility and cheap prices, as well as technical guidance and instructions, effectively solving customer usage problems.

About heparin sodium quees

Heparin sodium, as a commonly used anticoagulant for blood collection, plays an important role in medical and laboratory research. However, some key issues need to be noted when using heparin sodium to ensure its effectiveness and safety. Let's take a look at the issues to pay attention to when using heparin sodium.   1. Selection of dosage: The dosage of heparin sodium should be determined based on the specific situation and purpose. Different biochemical projects may require different levels of heparin sodium. For example, the recommended dose range for conventional test tubes is 12-30IU of heparin sodium per milliliter of blood, and the anticoagulation of micro blood collectors can be less than 14IU per milliliter of blood. Therefore, suitable heparin sodium test tubes should be selected for blood collection based on the examination items before use.   2. Preparation and storage: Heparin sodium is generally supplied in the form of raw powder, and appropriate preparation and dissolution are required before use. Generally, deionized water can be used for dissolution. It is important to follow the recommendations in the product manual during the preparation process to ensure that the concentration of dissolved heparin sodium meets experimental or clinical requirements. The prepared heparin sodium solution should be added in a timely manner. If it needs to be placed, it should be stored in a sterile environment at 0-4 ℃ as much as possible. The addition should be completed within a week, avoiding direct sunlight to maintain its stability.   3. Addition method: Generally, the addition method is divided into machine and manual methods. Regardless of which method is used, attention should be paid to completing it in a sterile state. If using a machine, it is necessary to clean its conveying pipeline and container, and disinfect and air dry it with alcohol to ensure that there are no impurities, bacteria, or scale attached to the pipe wall.   4. Inverted mixing: To ensure sufficient anticoagulation effect on blood, the test tube should be inverted and mixed as soon as possible after blood collection, especially when the temperature of the blood collection environment is too high. If not inverted in a timely manner, it may cause abnormal test results.   5. Timely testing: Pay attention to completing the test within 6 hours, as heparin is a non irreversible anticoagulant. If the test is not completed within the specified time, it is prone to result errors.   In summary, as an important anticoagulant for blood collection, heparin sodium needs to be used with caution and follow professional advice. Reasonable dosage and correct usage methods will help ensure the effectiveness and safety of heparin sodium, thus providing reliable support for clinical and laboratory research.   As a supplier of heparin sodium raw materials, Desheng not only provides high-quality products, but also can customize production according to customers' specific needs to meet the requirements of different experiments, while paying attention to providing comprehensive after-sales service.
