The effect of age, gender, and time between blood draw and start of centrifugation on the size outcomes of platelet-rich fibrin (PRF) membranes.

The findings from the present study demonstrate that on average, a clinician has approximately 60-90 s between blood draw and the start of the centrifugation cycle to produce standard-sized PRF membranes. Shortly thereafter, a significant reduction in size is observed. Additionally, females and older patients were found to produce larger PRF membranes. Centrifugation protocols may therefore be adapted accordingly.
