If PRF doubles, PRP becomes what relative?

If PRF doubles, PRP becomes what relative?

• A. Decreases by half
• B. Increases by the same amount
• C. Remains unchanged
• D. Doubles

Answer: (A)

This question hinges on how two platelet-rich products come from the same blood draw and thus compete for a finite supply. Platelets and plasma available for PRP and PRF come from a single pool. If the amount directed into PRF doubles, the amount remaining for PRP is reduced correspondingly. Under a fixed-resource assumption and redistribution between the two products, doubling PRF leaves PRP with half of its original yield. The other options would either ignore the redistribution from a shared pool or imply both would increase, which isn’t consistent with sharing the same finite resource. So PRP ends up decreasing by half.
