For those of you making whole blood derived platelets: I was wondering if other facilities allow a whole blood unit to be respun if the the original platelet rich plasma is unacceptable (bloody). Do you allow more than one respin? Does anyone know of a reference that limits the number of spins?

We thought about this and couldn`t find any reference that limited the number of spins. We would only do one extra spin though after re-mixing the unit.
