What effect does heparin lithium have on whole blood cell analysis

Details:

Heparin is an anticoagulant, mainly in the form of heparin sodium salt or heparin lithium salt. Its main function is to inhibit blood coagulation in blood collection vessels. Whole blood cytometry is a widely used instrument in the field of medical detection. Theoretically, potassium EDTA is an ideal anticoagulant for whole blood analysis, but heparin lithium anticoagulant is still needed in some specific needs. Although it has been said in some comments that "heparin anticoagulant" cannot be used for whole blood cell analysis, it must be corrected. The "heparin" here refers to "heparin sodium" rather than heparin lithium.

Heparin lithium powder

The reason why heparin anticoagulant can not be used in whole blood cell analysis is that excessive heparin will cause WBC aggregation, and heparin salt powder will cause leukocyte aggregation, which will affect the results of blood cell analysis. However, it was found that about 3.25% of heparin sodium did not significantly aggregate WBC and did not prevent PLT aggregation. 3.25% of heparin lithium could prevent WBC and PLT aggregation within 1 hour and PLT aggregation was slow within 2 hours. Conclusion heparin lithium anticoagulant can be used for whole blood cell analysis within one hour. In the experimental operation, the results of heparin lithium in whole blood cell analysis are the same as those measured by EDTA dipotassium.

Through the experiment, we also learned that 3.25% heparin lithium anticoagulant tube can also be used to check the samples of blood routine, liver function, kidney function and electrolyte. In this way, using one anticoagulant blood sample can check several items, which can not only save the cost, but also reduce the pollution of waste test samples to the environment.
