Do all vacuum blood collection tubes need additives?

 

Vacuum blood collection tubes are an important tool for virus detection in hospitals and play a pivotal role in the field of medical and health care. She is an important blood test equipment and apparatus. Additives for blood collection tubes are a key factor affecting the function of blood collection tubes. Commonly used additives are anticoagulants, coagulants, buffers, protective agents, separating gels, etc. This article will introduce several common blood collection tube anticoagulants and their effects. Anticoagulant, as the name implies, is a chemical agent that prevents blood from clotting. Commonly used anticoagulants for blood collection tubes are heparin sodium, heparin lithium, sodium citrate, potassium oxalate and ethylenediaminetetraacetic acid (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, citrate can form a soluble chelate with calcium ions in the blood, thereby preventing 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.

 

 

Ethylenediaminetetraacetic acid (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.

 

 

In summary, anticoagulants play an important role in blood vessel detection, but not all blood collection tubes contain anticoagulants. In blood collection tubes of different colors, green, blue, black, gray and purple caps are used in blood collection tubes. Contains anticoagulant, EDTA-2K is mainly used in purple anticoagulant tube.

 

 

Desheng Biotech specializes in the production of blood collection tube additives and has 15 years of production and research and development experience. Committed to providing complete blood testing solutions for hospitals, clinics and scientific research institutions across the country. Contains a series of products such as EDTA, lithium heparin, and anti-irradiation gel.
