Blood collection tube anticoagulant lithium heparin

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 tubes. Complete blood cytometer is a widely used instrument in the field of medical testing. In theory, dipotassium EDTA is an ideal reagent for anticoagulation in whole blood analysis, but in some specific needs, lithium heparin anticoagulants must be used. Although there have been some comments that "heparin anticoagulants" cannot be used for whole blood cell analysis, it must be corrected that the "heparin" here refers to "heparin sodium" rather than heparin lithium.
The reason why heparin anticoagulants cannot be used in whole blood cell analysis is that excessive heparin can cause WBC aggregation, and heparin salt powder can cause leukocyte aggregation, thereby affecting the results of blood cell analysis. However, the study found that about 3.25% of heparin sodium WBC does not aggregate significantly and does not prevent PLT aggregation. 3.25% heparin lithium can prevent WBC and PLT aggregation within 1 hour, and PLT aggregation is slow within 2 hours. It is concluded that lithium heparin anticoagulant can be used for whole blood cell analysis within one hour of blood draw. And in the experimental operation, the results obtained by lithium heparin in the whole blood cell analysis are not different from the results obtained by dipotassium EDTA.
Through experiments, we also learned that the 3.25% lithium heparin anticoagulation tube can also be used to check blood routine, liver function, kidney function, and electrolyte samples. In this way, one anticoagulated blood sample can check several items, not only can Cost savings can also reduce environmental pollution from discarded test samples.
