Giant platelets

Platelets (also called thrombocytes) are small blood cells that stick together to make blood clots that stop or slow bleeding when you have a cut or injury. Platelets are made in your bone marrow.

An MPV blood test is used to help diagnose or monitor many blood-related conditions. It may also help diagnose other health conditions or find out how serious they may be. A test called a platelet count, which measures the total number of platelets in your blood, is often done with an MVP test.
