[0002] A blood test is the collection of blood samples for examination, mainly to examine diseases of the circulatory system. Routine blood tests include hemoglobin determination, red blood cell count, white blood cell count, blood smear examination, microfilaria examination, erythrocyte sedimentation rate determination, platelet count, blood typing, etc. Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, bone marrow cytology, blood typing and cross-matching tests, which can detect the hematological characteristics of common blood diseases.

[0003] Serum is the liquid that precipitates after blood coagulation. The essence of blood coagulation is that the soluble fibrinogen in plasma is converted into insoluble fibrin. Fibrin is in the form of filaments, interweaving into a network, entrapping a large number of blood cells and easily forming a gel-like blood clot.
