Cold Apheresis Platelets in PAS

Cold Apheresis Platelets in PAS

This is a platelet transfusion study. The purpose of this study is to measure the life span and quality of platelets stored in a refrigerator. Participants will give platelets by apheresis. Platelets will be stored for 3 -20 days. A small portion of the subject's own stored platelets will be tagged with a radioactive isotope and infused back into the participant. This will enable us to track how many transfused platelets survive after storage in the refrigerator.

Procedure - Apheresis platelet collection

A single apheresis platelet unit will be collected from a healthy adult volunteer subject using the Trima Accel® Automated Blood Collection System. Concurrent plasma will be collected.

Refrigerated storage of apheresis platelets in PAS/plasma

The apheresis platelet unit will be stored, without agitation, at 4°C, for up to 20 days.

Radiation - Infusion of aliquot of autologous radiolabeled platelets

Fresh and stored aliquots will be labeled with Indium-111. We are administering ≤30 microcuries in both infusions for a total dose of 0.8 mSv.

In vitro tests

Tests to evaluate platelet function will be performed on the platelet unit on day of collection and end of storage
