Thrombocytopenia is defined as?

• A. Low platelet count
• B. High platelet count
• C. Low red blood cell count
• D. High white blood cell count

Answer: (A)

Thrombocytopenia means there are too few platelets. Platelets are the blood components that help form clots to stop bleeding, so when their numbers drop—below the normal range of about 150,000 to 450,000 per microliter—the body's ability to stop bleeding is impaired. That’s why this term specifically describes a low platelet count and not a high one or changes in red blood cells or white blood cells. A low platelet count is associated with symptoms like easy bruising, petechiae, and mucosal bleeding, and in severe cases can lead to spontaneous bleeding.
