Additional Information
Congenital platelet function abnormalities are rare. Many acquired conditions can interfere with normal platelet function. Aspirin is among the most common responsible agents, but many other drugs may alter platelet function. Patients with uremia, severe liver disease, or advanced alcohol related conditions often develop a complex bleeding diathesis that induces platelet dysfunction. Myeloproliferative disorders and dysproteinemias may exhibit similar problems.
