Platelet-rich fibrin (PRF) or leukocyte- and platelet-rich fibrin (L-PRF) is a derivative of PRP where autologous platelets and leukocytes are present in a complex fibrin matrix to accelerate the healing of soft and hard tissue and is used as a tissue-engineering scaffold in oral and maxillofacial surgeries. PRF falls under FDA Product Code KST, labeling it as a blood draw/Hematology product classifying it as 510(k) exempt.
