This is a prospective, open-label, non-randomized study to evaluate Trima Accel System modified postcount algorithm software.
Platelets will be collected according to the Trima Accel System Operator's Manual. Collection procedures will include those in which:
1. a single platelet product is collected
2. a double platelet product is collected, with or without other components.
Study participation will be up to 8 days. The apheresis procedure can last from 25 to 150 minutes, dependent upon the product(s) to be collected, machine configuration, donor parameters, the quality of the vascular access, and the tolerance of the donor to the citrate anticoagulant.
Donors will have one apheresis procedure and follow-up with any serious adverse events for 7 days.
