# Anticoagulant

An anticoagulant prevents blood from clotting between the draw and the spin. PRP protocols use one. PRF protocols deliberately do not, which is why PRF clots during centrifugation.

The choice of anticoagulant changes the product, not just the handling. It is one of the parameters that must be reported for a protocol to be reproducible.
