Anticoagulant EDTA K2 In Purple Head Cap Tube

When drawing blood, many people often wonder in their minds why the blood vessels are colorful, including red, purple and gray. In fact, it is very meaningful. Vacuum blood collection is distinguished according to the color of the cap. Test tubes of different colors have different functions for detecting blood. They usually provide convenience for medical staff to classify and process blood samples. One of the most common is the purple headcap tube. What is this purple headcap tube? Next, I will give you a detailed introduction.

In fact, the purple cap is called EDTA anticoagulant tube, which is suitable for routine hematological tests. In this EDTA purple test tube, the anticoagulant EDTA K2, also known as potassium EDTA, is usually added to prevent the blood sample from coagulating. Because it is an anticoagulant, it is not usually used for coagulation tests and platelet function tests.

EDTA K2 parameters:

EDTA K2 is one of the commonly used reagents in clinical testing. The main principle is that it has chelating force and can react with calcium ions in blood to form a stable chelate to prevent blood coagulation. It is suitable for whole blood and plasma testing, and is also the first test tube for blood routine, saccharified blood red egg white, and blood type testing.

In the routine blood test, the automatic blood analyzer is often used for more convenient detection of the collected blood samples, and statistical analysis of white blood cells and red blood cell count results. EDTA K2 produced by Desheng is a white crystalline powder, tasteless and soluble in water. When it is used to prepare anticoagulant and added into test tubes, it needs to be completely dissolved, that is, it needs sufficient anticoagulant time.

If there is no sufficient anticoagulation time, the blood test will be carried out, and the blood will have insufficient anticoagulation and blood clots, which will eventually lead to errors in the blood test results and affect the judgment of disease. Therefore, when using EDTA K2 as an anticoagulant for routine blood test, it is necessary to ensure sufficient anticoagulation time. In addition, when placing EDTA K2 into the blood collection vessel, it is necessary to gently rotate it to evenly distribute it around the inner wall of the test tube, so as to ensure that the blood sample fully contacts EDTA K2 and has anticoagulant effect.
