How often can I donate platelets?
The interval
Seven days between platelet donations, with a yearly maximum of 24. Your body replaces platelets within days.
Becoming a regular
Many centers welcome regular platelet donors and will help you set a recurring schedule. A reminder makes it easy.
Before each visit
Avoid aspirin for about two days beforehand, since it affects platelet function.
