Reducing unnecessary coagulation testing in hypertensive disorders of pregnancy

Abstract

Substantial coagulation testing was done on gravidas evaluated for a hypertensive disorder even though the prevalence of clinically significant abnormalities was low. Laboratory evaluation of patients suspected of having preeclampsia need not include a PT, aPTT, or fibrinogen test when there is no evidence of bleeding or of a condition that could produce coagulopathy and when the platelet count and lactate dehydrogenase level are both normal.
