IPSS-R Prognostic Values
PLATELETS
PLATELETS
Platelets, also called thrombocytes, are tiny blood cells that help your body form clots to stop bleeding. Platelets are produced in bone marrow by a process known as thrombopoiesis. Platelets are critical to blood coagulation and the formation of clots to stop bleeding.
A normal platelet count is between 150,000 to 450,000 platelets per microliter of blood.
