AbstractPrimary care physicians are often asked about easy bruising, excessive bleeding, or risk of bleeding before surgery. A thorough history, including a family history, will guide the appropriate work-up, and a physical examination may provide clues to diagnosis. A standardized bleeding score system can help physicians to organize the patient's bleeding history and to avoid overlooking the most common inherited bleeding disorder, von Willebrand's disease. In cases of suspected bleeding disorders, initial laboratory evaluations should include a complete blood count with platelet count, peripheral blood smear, prothrombin time, and partial thromboplastin time. More specialized yet relatively simple tests, such as the Platelet Function Analyzer-100, mixing studies, and inhibitor assays, may also be helpful. These tests can help diagnose platelet function disorders, quantitative platelet disorders, factor deficiencies, and factor inhibitors.
