Normal platelet count is within which range?

Normal platelet count is within which range?

• A. 150,000-400,000/mm3
• B. 50,000-150,000/mm3
• C. 300,000-500,000/mm3
• D. 100,000-200,000/mm3

Answer: (A)

Platelets are the small fragments that help form clots to stop bleeding, so their normal range reflects a balance between adequate hemostasis and avoiding unnecessary clotting. A typical adult platelet count is about 150,000 to 400,000 per microliter of blood. This range is considered normal in most laboratories and clinical guidelines. If the count drops below about 150,000, bleeding risk increases and even minor injuries can lead to noticeable bleeding. If it rises above about 400,000, there’s a higher risk of thrombosis. The range 150,000–400,000 best represents normal physiology, while the other options fall outside this standard normal interval.
