Did you know…?
About every two seconds, someone in the U.S. needs blood.
That means, this many people have needed blood since you arrived here:
Please note that, due to high COVID-19 infection rates in Santa Clara County, beginning December 16, 2022, Stanford Blood Center (SBC) requires that all donors, team members and volunteers at SBC donation locations be masked throughout the donation process, except while eating/drinking. You may wear either an SBC-provided procedural mask, your own personal mask, or a combination of the two, and procedural masks will continue to be supplied at all SBC locations for anyone who needs one.
Once safety allows, we will return to our flexible masking policy in accordance with CDC, state, and local guidance as well as Stanford Medicine policy. Learn more at stanfordbloodcenter.org/donation-faqs.
Blood Donation: How It Works
Before your appointment:
- Always be sure to drink plenty of water before donating blood!
- Eat an iron-rich meal. Eating enough iron is essential to ensuring that your hemoglobin level is right for donating. You can check out some tips on getting enough iron here.
- Bring your donor ID. If you have a donor ID, be sure to bring it with you to your appointment. First-time donors or returning donors without a donor ID card should bring a valid state-issued photo identification.
Avoid alcohol and fatty foods for 24 hours, and aspirin (if donating platelets) for 48 hours, before your donation.
After your blood donation:
- Always be sure to drink plenty of water to rehydrate.
- Sit down or lie down if you feel lightheaded or dizzy. Call our post-donation callback line at (650) 725-9968 if you feel unwell.
- Rest and replenish iron. We recommend you take an iron supplement and/or eat foods rich in iron combined with a source of vitamin C after your donation.
Avoid alcoholic beverages and vigorous exercise for at least 24 hours after donating, and be sure to keep that bandage on for a few hours!
Please call our post-donation callback line at (650) 725-9968 immediately if you:
- feel that your blood should not be given to a patient;
- are not sure that your blood is safe;
- develop a fever within 24 hours after donating;
- have any illness within two weeks of your donation; or
- are diagnosed by a physician as having West Nile, dengue, chikungunya, Zika, or Ebola virus Infection.
