5-Pack Platelet Update

Effective immediately, Michigan Blood no longer provides 5-pack platelets and Spectrum Health Blood Bank has changed nomenclature for platelet units when they are ordered. In the past, platelets were ordered as a 5-pack which came from 5 separate donors and had a volume of 250 mL. Current process is one single unit of pheresed platelets which comes from a single donor. The volume is 250 mL, an equivalent volume as a 5-pack of pooled random donor platelets. The bonus is that there are now fewer donor exposures when transfusing a unit of platelets. The 5:5:1 ratio still applies for MTPs (massive transfusions).
