What tests can heparin be used for?

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 also has relatively less interference to blood components. It will not affect the volume of red blood cells and cause hemolysis. Therefore, in the detection of whole blood samples, Heparin is used as a blood anticoagulant.

In addition to being used in blood testing, heparin is suitable for erythrocyte fragility test, blood gas analysis, hematocrit test, hemorheology and emergency biochemical determination. 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. When measured by urease program, heparin ammonium may increase serum urea nitrogen level. In addition, heparin lithium has the least possibility of interference in the detection of non lithium ions, so heparin lithium is recommended as an anticoagulant. At present, heparin lithium is gradually replacing heparin sodium in blood test.
