What is the normal range for platelets?

• A. 50,000-150,000/mm³
• B. 200,000-600,000/mm³
• C. 150,000-450,000/mm³
• D. 1,500,000-2,000,000/mm³

Answer: (C)

Platelets are the blood cells that help stop bleeding by forming a clot. A normal platelet count sits in a range that supports hemostasis without excessive clotting. The standard reference is about 150,000 to 450,000 platelets per microliter (per mm³). Values below this range raise the risk of bleeding with injury or surgery, while values well above it can indicate reactive processes or disorders that cause too many platelets. Therefore, 150,000-450,000/mm³ is the normal range.
