Treatment of Patients Over anticoagulated with Warfarin



Transfusion Medicine (Platelet Dosing)


The “buffy coat” method for preparing platelet concentrates, implemented by CBS in May 2007, has changed the way platelet concentrates should be ordered.

Previously, the standard adult dose of platelets was five random donor platelets which were pooled into a single adult dose in the hospital laboratory. The “buffy coat” technology permits the recovery of an equivalent dosage of platelets from four donors. Canadian Blood Services is now supplying hospitals with a pre-pooled, single unit, of platelet concentrate from four donors. The historical random donor platelet concentrate has been discontinued.
