Platelets can be stored at
**Core Concept**
Platelet storage is a critical aspect of transfusion medicine, with implications for the quality and safety of transfused blood products. Platelets are fragile cells that require specific storage conditions to maintain their viability and function.
**Why the Correct Answer is Right**
Platelets can be stored at room temperature (20-24°C) with continuous gentle agitation for up to 5-7 days. This is because platelets can survive without the need for refrigeration due to their unique metabolic pathways, which allow them to generate ATP through glycolysis. The agitation helps to prevent platelet clumping and maintains their viability. The storage container must be specifically designed to maintain the platelets in a single layer, with minimal contact between platelets, to prevent activation and aggregation.
**Why Each Wrong Option is Incorrect**
* **Option A:** Platelets cannot be stored at 4°C, as this temperature slows down glycolysis and leads to platelet activation and aggregation.
* **Option B:** Platelets cannot be stored for more than 5-7 days, as prolonged storage leads to a decline in platelet function and viability.
* **Option C:** Platelets require refrigeration to prevent bacterial growth, but they cannot be stored at refrigerated temperatures (4°C) for extended periods.
**Clinical Pearl / High-Yield Fact**
Platelets should be stored in a specific container with a gas-permeable bag to maintain the optimal storage conditions, and the storage solution should contain nutrients and additives to support platelet viability.
**Correct Answer: C. 24-48 hours**
