This thixotropy causes serum separation gel to form an isolation layer between serum and blood cells, and the specific gravity of serum separation gel is between serum and blood cells. Therefore, after blood centrifugation, it can form layered blood clots, separation gel, and serum. Effectively separate serum and blood cells. This makes serum separation gel play an important role in clinical testing.   In clinical testing, serum separation gel is mainly used to separate serum and blood cells, prevent material exchange between serum and blood cells, and ensure the accuracy of test results. By using serum separation gel, the operation process can be simplified, manual intervention and error rate can be reduced, and the accuracy and efficiency of detection can be improved.   The advantages of serum separation gel   1. Efficient separation: It can quickly and efficiently separate serum and blood cells, ensuring the accuracy of experimental results;   2. Maintaining blood purity: It can isolate the contact between serum and blood cells, prevent substances with higher content in blood cells from being released into the serum.

Heparin is a commonly used anticoagulant in clinical practice, widely used in blood tests and various medical procedures. Generally, it has two salt forms, namely sodium heparin and lithium heparin, both of which play an anticoagulant role. However, although their effects are similar, their binding ions and degree of dissociation are different. Heparin lithium exhibits better anticoagulant effects than heparin sodium in certain situations and is more suitable for certain blood test items. Let's take a look at the blood test items suitable for heparin lithium.   1、 Biochemical testing of patients after hemodialysis   For biochemical tests of hemodialysis patients, heparin lithium plays a significant role. For example, during hemodialysis, the dialysate usually contains heparin anticoagulants, such as low molecular weight heparin calcium. These anticoagulants can make blood samples less prone to clotting, making it difficult to separate samples and obtain plasma. Therefore, using heparin lithium anticoagulant plasma is an ideal choice for biochemical testing in dialysis patients. It not only effectively prevents blood clotting, but also helps to extract accurate plasma samples. According to reports, the accuracy of the results is high.   2、 Liver function examination   Blood samples treated with lithium heparin also have a special role in liver function tests, which usually involve the analysis of multiple blood parameters to evaluate liver health, effectively treat or prevent diseases. The use of heparin lithium tubes for examination, such as in the detection of liver diseases such as hepatitis, liver cancer, and fatty liver, helps to maintain blood flow, make the measurement of various blood parameters more accurate, and thus improve the efficiency of the examination work.   3、 Hemorheological testing   In the detection of cardiovascular and cerebrovascular diseases, the rheological properties of blood are very important. Some diseases, such as high viscosity, lead to abnormal increases in blood viscosity, which may increase the risk of thrombosis and cardiovascular disease. In these cases, hemorheological testing can help identify risk factors. Heparin lithium, as an anticoagulant, can be used to ensure that blood maintains fluidity during rheological testing, without causing inaccurate results due to coagulation, which is helpful for early diagnosis of cardiovascular and cerebrovascular diseases.   Lithium heparin is widely used in blood tests, and its superior anticoagulant performance makes it an ideal choice for medical staff. As a manufacturer of lithium heparin raw materials, Desheng can supply high-quality reagents of analytical grade.

In the modern medical field, the collection and analysis of blood samples are very common clinical operations, and blood testing is one of the important ways for doctors to diagnose and monitor the health status of patients. To ensure that the collected blood samples do not coagulate after collection and to ensure accurate experimental results, appropriate anticoagulants need to be used. And the heparin lithium collection tube is one of them, and its working principle and application will be introduced below.   1、 The working principle of heparin lithium   Heparin lithium is an anticoagulant reagent, usually prepared as a solution from powder and sprayed onto the inner wall of blood collection vessels. Its main function is to prevent blood from clotting after collection, ensuring that the blood sample remains in its original state for subsequent testing. The anticoagulant mechanism is mainly due to the fact that heparin lithium can bind with antithrombin III (AT-III) to form the heparin AT-III complex. AT-III is a naturally occurring protease inhibitor that can reduce the activity of coagulation factors such as Xa and IIa. By binding to AT-III, coagulation factors are inactivated, thereby inhibiting the formation of prothrombin kinase and further preventing blood clotting.   2、 Application of heparin lithium collection tube   Lithium heparin collection tubes have a wide range of applications in medical laboratories and clinical practice. Firstly, it is commonly used in biochemical tests to evaluate liver function, kidney function, glucose metabolism, lipid metabolism, etc. It can ensure that blood samples remain stable after collection, thereby providing reliable detection results. In addition, in coagulation tests, it is necessary to analyze coagulation factors in the plasma, such as PT (prothrombin time) and APTT (activated partial coagulation time). The heparin lithium collection tube can ensure the stability of the plasma and is suitable for these tests.   3、 Precautions for using heparin lithium collection tubes   To ensure sufficient anticoagulation of the blood in the collection tube, the blood sample should be reversed and mixed 5-8 times as soon as possible after collection, especially when the blood collection environment is above 25 degrees Celsius. Effective contact between the blood and heparin lithium must be ensured, otherwise local coagulation and non coagulation may occur, which is not conducive to subsequent testing. In addition, as heparin anticoagulation is not irreversible, the collection tube should be tested within 6 hours after blood collection and should not be left idle for a long time, which may cause accidents.   Overall, the use of heparin lithium collection tubes in medical laboratories ensures the accuracy and reliability of blood samples, helping medical staff to make accurate diagnoses and treatments. This anticoagulant is also recognized as an ideal anticoagulant in the medical field. Note that when using heparin lithium collection tubes, it is necessary to follow standard blood collection procedures and operating procedures to ensure the quality of the collected samples.   As a supplier of blood vessel additives, Desheng can provide high-quality raw material powders and has the ability to provide long-term supply and improve after-sales service.
