Which statement is a true step in platelet component production?

• A. Soft spin to sediment red blood cells
• B. Resting phase at 20C to 24C
• C. Resting phase at 1C to 6C
• D. Hard spin to separate platelets from PRP

Answer: (B)

Platelets must be handled at the right temperature during processing to keep them viable and functional. After the initial separation, a resting period at room temperature (about 20–24°C) lets platelets recover from the shear and stress of centrifugation, helping preserve their function for transfusion. Resting at colder temperatures (1–6°C) would impair platelet function and is not used during processing. While steps like concentrating platelets from platelet-rich plasma can involve spins, the room-temperature resting phase is the step that directly supports maintaining platelet quality in production.
