The relationship between blood and various additives for blood collection
Blood is a red opaque viscous liquid that flows in the blood vessels and heart of a person, with functions such as transporting oxygen, regulating body temperature, regulating osmotic pressure, and acid-base balance. Blood is mainly divided into two parts: serum and blood clots, and serum is composed of plasma, white blood cells, and platelets; Blood clots are commonly referred to as blood cells.

When physiological or pathological changes occur in the human body, they often cause changes in blood composition. Therefore, analyzing and studying the pathological changes in blood and hematopoietic organs can help determine a person's physical condition. The addition of blood collection vessels has emerged as a very important auxiliary reagent in blood testing.

1. Silicifying agent. Firstly, the blood collection vessel will undergo silicification treatment. The use of silicification agents can not only effectively prevent the occurrence of coagulation or hemolysis in blood samples, but also make the inner wall of the blood collection vessel smooth and close to the shape of the human blood vessel inner wall, effectively maintaining the original characteristics of the blood sample and making subsequent test results more accurate.

2. Serum separation gel and coagulant. When testing serum, blood collection vessels without any additives and only subjected to silicification treatment can be used, and blood samples can naturally coagulate to form bleeding serum; Blood collection vessels containing serum separation gel and coagulant can also be used, as the name suggests, to promote blood coagulation. Serum separation gel can effectively separate serum and blood clots.

3. Anticoagulant. When conducting relevant tests on plasma or whole blood, blood anticoagulants are required to prevent blood clotting during the examination. Common blood anticoagulants include heparin series, EDTA potassium salt series, and trisodium citrate, which have different anticoagulant mechanisms and need to be selected based on actual testing items.
