What Is a Platelet Assay?
The platelet life span is about 7 to 14 days, and about 1/10 of the total number is updated every day. Most of the senescent platelets are cleared in the spleen. Platelet numbers often change depending on the physical condition. The abnormal platelet life has certain clinical significance for the diagnosis and treatment of bleeding disorders.

- [Clinical significance]
- The number of platelets in healthy adults is 100-300 × 109 / L. Platelet numbers often change depending on the physical condition. Most of the senescent platelets are engulfed and destroyed by the spleen, liver and bone marrow mononuclear-macrophages. The main site of platelet destruction is the spleen, followed by the liver. The destruction of the two accounts for about 75% of the total destruction. Platelets are destroyed in the blood circulation. If the body surface is measured for radioactivity, it will have certain clinical significance for the treatment of diseases.
- Platelets have the characteristics of adhesion, aggregation, contraction and release, and adsorption. When these characteristics are abnormal, they will directly affect the hemostatic and coagulation functions. Platelet life is shortened in primary or immune thrombocytopenic purpura, and prolonged in patients with erythrocytosis accompanied by thrombocytosis. The abnormal platelet life has certain clinical significance for the diagnosis and treatment of bleeding disorders.
