How often can I donate platelets?
What this means
- The interval between platelet donations is 7 days.
- The yearly maximum is 24 donations.
- Avoid aspirin for about two days before a platelet appointment.
What to do next
Set a recurring reminder if you want to be a regular platelet donor.
When to call the center: Call your platelet center about scheduling a regular slot.
Why this rule exists
Platelets are replaced quickly, which is why the interval is short.
This is general educational guidance, not a final eligibility decision. Donation centers make final eligibility decisions during confidential screening. Rules may vary by center, donation type, location, and current policy.
