What is the normal platelet count range?

• A. 50,000-150,000
• B. 150,000-400,000
• C. 400,000-600,000
• D. 1,000,000-2,000,000

Answer: (B)

Platelets are the blood components that help stop bleeding by forming clots. The usual circulating range is about 150,000 to 400,000 platelets per microliter of blood. This window balances the need to form clots when injury occurs with the risk of excessive clotting if there are too many platelets. Values below this range suggest thrombocytopenia and a bleeding tendency, while values above indicate thrombocytosis and a higher risk of thrombosis. So the normal range fits as 150,000-400,000.
