Critical count of Platelet is `:-`

Options

A. `40,000/m m^(3)
B. 1 lac / m m^(3)
C. 2 lac / m m^(3)
D. 4 lac / m m^(3)

Answer

**Step-by-Step Solution:**

1. **Understanding Platelets (Thrombocytes):**
- Platelets, also known as thrombocytes, are small cell fragments in the blood that play a crucial role in the clotting process. They help to stop bleeding by forming clots at the site of injury.

2. **Normal Platelet Count:**
- The normal range for platelet count is typically between 150,000 to 450,000 platelets per microliter of blood (or mm³).

3. **Critical Count Definition:**
- A critical count refers to a level of platelets that is dangerously low and can lead to excessive bleeding.

4. **Determining Critical Count:**
- The critical count of platelets is defined as being less than 150,000 platelets per microliter. Specifically, a count below 40,000 platelets per microliter is considered critical and can pose serious health risks.

5. **Final Answer:**
- Therefore, the critical count of platelets is **less than 150,000 platelets per microliter**, with a specific critical threshold being **40,000 platelets per microliter**.
