Platelet Count
Alternate Names : Thrombocyte Count
Definition This is a test to measure the number of platelets in blood.
Platelets are necessary for normal blood clotting (hemostasis). Most important, they aggregate (clump together) to plug small holes in damaged blood vessels. They also activate factor VIII (a component of the coagulation cascade) and release phospholipids necessary for coagulation.
