This is a platelet transfusion study. The primary purpose of this study is to determine if Biotin (vitamin B7) is an effective way to label platelets in survival and recovery studies. This study involves using a radioactive material as well as Biotin added to your platelets to track platelets in your blood. Your platelets will be collected using an apheresis procedure, labeled with biotin, and stored for 3 days. After the storage period, a radioactive material will be added to a small amount of your stored biotin-treated platelets. Your radiolabeled platelets will be given back to you and follow-up blood draws will be done to see how many of your platelets are circulating.<\/p>\n

There will be a total of 12 visits over 180 days days. Each study visit lasts from 30 minutes to 3 hours.
\nStudy visits will occur at Bloodworks Northwest – 1551 Eastlake Ave. East, Suite 100, Seattle, WA 98102.
\nParticipants will be compensated up to $1500.00 for time involved in the study.<\/p>\n
