A randomized controlled trial evaluating recovery and survival of 6% dimethyl sulfoxide–frozen autologous platelets in healthy volunteers

BACKGROUND: Availability of platelets (PLTs) is severely limited by shelf life in some settings. Our objective was to determine and compare to Food and Drug Administration (FDA) criteria the PLT recovery and survival of autologous PLTs cryopreserved at −65°C or less in 6% dimethyl sulfoxide (DMSO) reconstituted with a no‐wash method (cryopreserved PLTs [CPPs]) compared to autologous fresh PLTs.
