Overview
Routine laboratory studies in patient with intracerebral hemorrhage should include complete blood count (CBC) with platelets, electrolytes, renal function, coagulation studies (prothrombin time (PT), partial thromboplastin time (PTT), and INR), toxicology screen, blood glucose level, and pregnancy test in women of childbearing age.[1][2][3][4][5]
