Does donating blood platelets hurt?
Donating blood platelets does not hurt.  You might feel a pinch when the needle itself first goes into your arm.  During that pinch, think about the patient - maybe a young child, mother, or a grandparent - who is really in need of your gift.  A moment of discomfort on your end will help to save a life.
What should I bring at the time of donation?
  • A valid photo ID (driver's license, passport, etc.)
  • A list of medications you are taking (our medical interviewer needs to know what medications you are taking or have recently taken)
  • A list of places you have visited outside of the U.S. in the past 3 years
  • A friend to donate with you! (it's a great way to enhance this life saving experience by enjoying it with a friend)
I am taking certain medications, can I still donate?
Many medications are acceptable. Consult your physician or contact us if you have questions about your eligibility to donate.
Can I exercise after donating?
Light exercise is fine.  Avoid strenuous activity and heavy lifting for about 24 hours.
How much time does it take for my body to replace the blood platelets that I donated?
The volume of fluids will adjust within a few hours of your donation.  Blood platelets will be replaced within 3 days.  Donors receive back into their body at the time of donation those blood products that aren't used.
What tests are done on blood?
Blood is tested for hepatitis B and C, HIV, syphilis, Chagas Disease, West Nile Virus, HTLV, and cytomegalovirus.  In addition, it is tested for ABO group (blood type) and RH type (positive or negative) as well as tests for certain antibodies.
If I have a positive blood test, how will I be notified?

You will receive a letter from HemaCare Blood and Platelet Donor Center.  In some cases you will also receive a phone call.

What kinds of questions will be asked when I come to donate?
You will be asked questions about your health and whether you are at risk for certain diseases including AIDS, hepatitis, Creutzfeldt-Jakob disease, and West Nile virus.
How long does it take to donate?
From when you walk in to when you walk out, it takes approximately 3 hours to donate blood platelets.
Can I get a disease from donating?
No, all of the materials used during your donation are pre-packaged, sterile, and disposable.  Once it is used, it is thrown away and destroyed.
Is there any substitute for blood?
No. Currently, there is no substitute for blood; however, there have been many attempts and research is ongoing.
Is there an upper age limit to donate?
There is not an upper age limit for donating, but there is a lower age limit.  You must be at least 18 years old to donate blood platelets.  For more information, please review the eligibility requirements page.
Can I be paid for donating?
No, donations are strictly voluntary.  We hope the reward for donating is the self-satisfaction and gratification knowing that up to three lives were brightened and saved with your donation.
If I was deferred once before, am I still ineligible to donate?
We will contact donors who are permanently deferred.  Temporary deferrals are eligible to donate once their deferral period has expired.  Prior to each donation, donors complete a mini-physical and medical interview.  At that time, eligibility for donating on that particular day is determined.  If you are deferred, it doesn't mean you can't still help! Scientists are always in need of blood components for their studies – become a research donor!
