Role of heparin in biochemical detection

Details:

Heparin is widely used in clinical blood testing, mainly heparin lithium and heparin sodium, which are the most common. Because it has the smallest chelation characteristics, the smallest interference to water and relatively low cation concentration, it has relatively less interference to blood components. It will not affect the volume of red blood cells and cause hemolysis. Therefore, heparin is used as blood anticoagulant in the detection of whole blood samples.

In addition to being used in blood testing, heparin is suitable for erythrocyte fragility test, blood gas analysis, hematocrit test, hemorheology and emergency biochemical test. In the detection of pH value, blood gas, electrolyte and calcium ion, heparin is the preferred anticoagulant. However, for electrolyte test, heparin lithium shows higher accuracy than other tests. Heparin sodium may overestimate sodium level, and heparin ammonium may increase serum urea nitrogen level when measured by urease program. In addition, heparin lithium has the least possibility of interference when detecting non lithium ions, so heparin lithium is recommended as an anticoagulant. At present, heparin lithium is also gradually replacing heparin sodium in blood test.

With the market demand for heparin, there are many brands on the market. Desheng company is a manufacturer specializing in the production of blood collection additive series products. It has been more than ten years since its establishment in 2005. Its products mainly include heparin lithium, heparin sodium, serum separation gel, EDTA dipotassium / Tripotassium, coagulant, coagulant powder, potassium oxalate, silicide and other products.
