There are many types of blood collection tube additives, and after these additives are added to blood collection tubes, they are generally distinguished according to the color of the blood collection tube cap. Vacuum blood collection tubes are important blood testing equipment and instruments. The use of additives in blood collection tubes is a key factor affecting the function of blood collection tubes. Commonly used additives include anticoagulants, coagulants, buffers, protective agents, separating gels, etc. And what are the anticoagulant products, and how much do you know?
As the name suggests, anticoagulants are chemical reagents that prevent blood from clotting. Commonly used anticoagulants for blood collection tubes are sodium heparin, lithium heparin, sodium citrate, potassium oxalate and EDTA.
Heparin is considered to be the best anticoagulant in the determination of blood chemical composition. Sodium and lithium salts are commonly used in clinical blood tests and have unique application value. Heparin is mainly found in blood collection tubes with green caps, and is suitable for red blood cell fragility test, blood gas analysis, hematocrit test, blood rheology and emergency biochemical determination.
Lithium heparin has the least possibility of interference when detecting non-lithium ions, and has better anticoagulant activity than heparin sodium. At present, heparin lithium is gradually replacing heparin sodium in blood tests.
Sodium citrate is also known as: sodium citrate. Citrate can form soluble chelate with calcium ions in the blood to prevent blood clotting. It is generally used for checking blood coagulation and blood cell deposition rate.
Sodium citrate is used as an anticoagulant in anticoagulant tubes with light blue caps and ESR tubes with black caps.
Potassium oxalate is an anticoagulant with high dissolution concentration and strong anticoagulant effect. The principle of action is that oxalate and blood calcium ions form calcium oxalate precipitation and tissue coagulation. It is often used for anticoagulation of blood samples for testing.
Potassium oxalate is often mixed with sodium fluoride, and it is present in the gray cap anticoagulation blood collection tube.
EDTA is one of the most commonly used and most important anticoagulants and reagents in clinical examinations. EDTA can combine with calcium ions in the blood to form a chelate, and Ca2+ loses the coagulation effect, thereby preventing blood coagulation. It is suitable for a number of hematological examinations. The commonly used EDTA anticoagulant is EDTA-2K.
The EDTA purple tube cap anticoagulant blood collection tube is suitable for whole blood and plasma testing. It is the first choice for blood routine, glycosylated hemoglobin, and blood group testing.
It has been learned from the above that anticoagulants play a vital role in blood collection tubes, but in addition to anticoagulants, there are many other types of blood collection tube additives. And our company is a manufacturer specializing in the production of blood collection tube additives. The products we produce blood collection tube additives include: heparin sodium, heparin lithium, serum separation gel, EDTA-2K (3K), EDTA-2NA, coagulant, and high-efficiency coagulation accelerator Powder, water-soluble siliconizing agent, oleosilicon, potassium oxalate, trisodium citrate, sodium fluoride, etc. If you want to know about the products, you can call for consultation.
