Platelets are given in case of

Options

A. Anaemia
B. Polycythemia
C. Thrombocytopenia
D. Leukopenia

Answer

**Step-by-Step Solution:**

1. **Understanding Platelets:** Platelets, also known as thrombocytes, are small cell fragments in the blood that play a crucial role in the process of blood clotting. They help prevent excessive bleeding when injuries occur.

2. **Normal Platelet Count:** The normal range for platelet count in a healthy adult is approximately 150,000 to 450,000 platelets per microliter of blood. This count is essential for maintaining proper blood clotting functions.

3. **Conditions Requiring Platelet Transfusion:** Platelets are administered in specific medical conditions where the platelet count is abnormally low. These conditions include:
- **Thrombocytopenia:** A condition characterized by a low platelet count, which can lead to increased bleeding and bruising.
- **Anemia:** A condition where there is a deficiency of red blood cells or hemoglobin, but platelets are not specifically given for this condition.
- **Polycythemia:** A condition with an increased number of red blood cells, which does not typically require platelet transfusion.
- **Leukopenia:** A condition characterized by a low white blood cell count, which also does not directly relate to platelet transfusion.

4. **Conclusion:** Among the mentioned conditions, thrombocytopenia is the primary condition that necessitates the administration of platelets to restore normal clotting function and prevent bleeding complications.

**Final Answer:** Platelets are given in case of thrombocytopenia.
