What storage method is appropriate for platelets prepared by the PRP method?

Platelets prepared by the Platelet Rich Plasma (PRP) method are best stored at a temperature range of 22 ˚C to 24 ˚C, which is known as room temperature. This temperature range is crucial for maintaining platelet viability and function. At these temperatures, platelets can be stored for a limited period (typically up to five days), during which they remain active and capable of responding appropriately when transfused into a patient.

Storage at lower temperatures, such as 4 ˚C, can significantly impair platelet function due to metabolic changes and potential activation of the platelets. Additionally, subzero temperatures, like -20 ˚C or -40 ˚C, are unsuitable for platelet preservation because freezing can cause ice crystal formation, leading to irreversible damage to the platelets and rendering them non-functional. Thus, the optimal storage practice for platelets prepared via PRP is indeed at the specified room temperature, ensuring both their safety and efficacy when transfused.
