Platelet Donation FAQs

Does my blood type make a difference?

If you are blood type AB, your platelets are especially valuable to certain patient populations. However, platelet donors of all blood types are always needed and welcomed!

What should I do to get ready for my platelet donation appointment?

  • Eat a nutritious and filling meal on the day of your appointment (including plenty of calcium).

  • Make sure you are well-hydrated. Try to drink six to eight 8-ounce glasses of water the day before and the day of your donation.

  • Bring a valid photo ID with you to your appointment.

Does donating platelets hurt? Will it make me feel sleepy?

Most people say they only feel a slight pinch of the needle at the start of the donation. Because platelet donors get their oxygen-carrying red cells back, donors report feeling less tired than after giving blood. (Many people also report feeling great after donating because they know they've helped patients in need!)

What should I do after my platelet donation appointment?

  • We encourage donors to drink plenty of good fluids (water and juices) after donating. This will help keep your body well-hydrated.

  • Eat well the day of your donation and don’t hesitate to snack if you feel hungry.

How often can I donate platelets?

As long as you are healthy and continue to meet the eligibility criteria, you can safely donate every seven days. Many of our platelet donors schedule regular appointments every other week. While you can donate every seven days, you can only donate platelets 24 times every 365 days.
