What can heparin be used for

Details:

Heparin is widely used in clinical blood testing, mainly heparin lithium and heparin sodium are the most common. Because it has the minimum chelating characteristics, the smallest interference to water and relatively low cation concentration, so it has relatively little interference on blood components, it will not affect the volume of red blood cells, nor cause hemolysis. Therefore, in the detection of whole blood samples, heparin is not able to affect the volume of red blood cells and hemolysis, Heparin is used as a blood anticoagulant.

Lithium heparin powder

Heparin is suitable for the tests of red cell fragility, blood gas analysis, hematocrit, hemorheology and emergency biochemical determination. Heparin is the first anticoagulant in the detection of pH value, blood gas, electrolyte and calcium ion. However, for electrolyte test, heparin lithium showed higher accuracy than other tests, heparin sodium may overestimate sodium level, and heparin ammonium may increase the level of urea nitrogen in serum when measured by urease program. In addition, the possibility of interference caused by heparin lithium in the detection of non lithium ion is the least, so heparin lithium is recommended as anticoagulant. At present, heparin lithium is gradually replacing heparin sodium in blood test.
