What is the normal range of platelet count in patients?

  1. 50k-200k

  2. 150k-400k

  3. 200k-600k

  4. 100k-300k

The correct answer is: 150k-400k

The normal range of platelet count in patients typically falls between 150,000 to 400,000 platelets per microliter of blood. This range is important because it indicates the level of platelets necessary for proper blood clotting and overall hemostatic function. When the platelet count is within this range, it signifies a healthy capacity for the body to respond to bleeding and injury. A count below this range may indicate thrombocytopenia, which can lead to excessive bleeding or bruising, while a count above can suggest thrombocytosis, potentially leading to clotting issues. This understanding is crucial for diagnosing hematological disorders and managing patients effectively in a clinical setting.
