Concentrated PRF (C-PRF)
C-PRF is a platelet-rich fibrin variant in which the upper plasma layer is fractionated to isolate the fraction with the highest platelet and leukocyte concentration, rather than using the whole liquid layer.

Fractionating the plasma layer
Figure. C-PRF isolates the fraction of the upper layer with the highest platelet and leukocyte concentration rather than using the whole liquid layer. It is a pipetting technique, and it is therefore more sensitive to operator skill than most protocols.
In practice
C-PRF is a preparation technique rather than a machine capability. It requires careful, layered pipetting and is therefore more sensitive to operator skill than most protocols.
