Coagulopathies related to deficiencies of protein C, protein S, antithrombin III, or plasminogen; activated protein C resistance; prothrombin gene mutation; presence of anticardiolipin antibodies or lupus anticoagulant; or elevated homocysteine can be evaluated with various coagulation testing strategies in patients with suspected hypercoagulable states.2 Evaluation of prolactin levels can be used to identify a very recent seizure.
