PLATELET COUNT

No special preparation is required.

Platelets participate in primary hemostasis by forming a platelet plug at sites of vascular injury. Average life span of platelets is 7-10 days. Low platelet count may occur due to decreased production eg. bone marrow failure, increased consumption eg. idiopathic thrombocytopenic purpura, increased sequestration eg. hypersplenism or a combination of these causes.
