Repeat test.: A shortened clotting time that does not appear to reflect technical error has been associated with an increased risk of thrombosis, recurrent thrombosis, recurrent miscarriage, or bleeding, and may increase the risk of thrombosis associated with other common thrombotic risk factors (eg, factor v leiden, obesity, increased levels of d-dimer). ...Read more
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 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. ...Read more
Measures clot factor: This is a test that measures clotting factor activity. All these factors are synthesized in the liver, except factor viii, so this is also a check on the capability of the liver as well. If this is high, it can be from a deficiency or incabability of the factors or a liver failure issue, like cirrhosis, or a vitamin k deficiency from fat malabsorption.

Prothrombin time = 15.8 ses, does that mean i am k deficient? why does it increase? what are normal values? hvy periods, fibroid, lysteda, treatment?
INR matters more: Different labs have different standards for prothrombin times. To standardize, labs report a value called "INR." INR of 1 is normal. Elevated INR in the absence of taking warfarin/Coumadin can occur with certain abnormalities of the clotting system, vitamin K deficiency, liver disease (inability to make clotting factors), or may just be within margin of error for the lab & in need of repeating. ...Read moreSee 1 more doctor answer
