PRP and PRF are ______ related.

PRP and PRF are ______ related.

• A. Directly
• B. Inversely
• C. Proportionally
• D. Unrelated

Answer: (B)

PRP and PRF are two forms of platelet concentrates obtained from the same blood sample, but they appear as different products depending on how you process the blood. PRP is a liquid platelet-rich plasma formed using anticoagulants and specific centrifugation to keep platelets suspended in plasma. PRF, by contrast, is a fibrin-based clot formed without anticoagulants, trapping platelets in a solid fibrin matrix. Because platelets are either kept in the liquid phase (PRP) or trapped in the fibrin clot (PRF), increasing one tends to reduce the other. So they are inversely related.
