As an additive for blood collection, heparin lithium plays an indispensable role in blood collection and processing. Due to its many characteristics and ideal anticoagulant effects, it has become the preferred reagent for blood collection and sample processing. Below, we will focus on understanding the role of heparin lithium additive and its importance in medical practice.
Basic characteristics of heparin lithium
Heparin lithium is a derivative of heparin, which is a polysaccharide compound extracted from the intestinal mucosa of pigs, cows, or sheep. Its molecular structure contains sulfate groups, which give heparin lithium a negative charge. This negative charge is key to its anticoagulant properties, as it can interfere with the coagulation process and prevent blood clotting.
Application of heparin lithium in blood collection
Lithium heparin has a wide range of applications in the field of medical diagnosis, mainly reflected in the following aspects:
1. Blood collection tube anticoagulant: Heparin lithium is often added to the inner coating of the blood collection tube to prevent blood from clotting during the collection process, maintain the original state of the blood sample, ensure the stability of the blood sample, and improve detection efficiency.
2. Test items: The blood samples collected from heparin lithium anticoagulant tubes are usually used for various biochemical tests, including liver and kidney function measurements, blood lipids, blood glucose, blood gas analysis, etc., to ensure that the blood samples will not coagulate during testing, thus ensuring reliable results.
3. Plasma preparation: The anticoagulant effect of heparin lithium is particularly important for plasma preparation. Through centrifugation, plasma can be separated from blood cells and used for various clinical and research applications, such as plasma protein analysis, coagulation factor determination, and immunological research.
The importance of heparin lithium in medical practice is obvious. It is not only an effective tool for medical staff to work, but also provides guarantees for the treatment and prevention of patients' diseases.
