A member asked:

What is thrombocytopenia and how is a prothrombin time test used?

A doctor has provided 1 answer

Blood clotting: Thrombocytopenia means low level of blood plateletes. Prothrombin time is a test for extrinsic coagulation pathway that is initiated with factor vii. Vitamin k deficiency or use of Coumadin (warfarin) or liver function deficiency will prolong the prothrombin time, while several blood clotting diseases that affect intrinsic coagulation such as von willibrand or hemophila will not affect prothrombin time.
