Platelet count/ Thrombocyte count Indications :
Test is used to evaluate, diagnose, and follow up bleeding disorders, purpura/petechiae, drug induced thrombocytopenia, idiopathic thrombocytopenia purpura, disseminated intravascular coagulation, leukemia, and chemotherapy management of malignant disease.
Platelets are generally 2-3 microns diameter but large forms appear when production is increased. The production of platelets is controlled by thrombopoietin. Platelets survive for 8-10 days and are subject to circadian periodicity highest platelet counts occurring during midday. Some drugs may increase the platelet count by stimulating thrombopoietin production. Normal Range :

The platelet, of growing practical clinical importance in hemostatic considerations and a variety of medical/surgical processes, is also fundamental to etiology considerations of arteriosclerosis and malignant disease.Click Here To View Interpretation Values Critical Values :
