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:
If you’ve received the Pfizer, Moderna or Johnson & Johnson vaccine for COVID-19, you are still eligible to donate blood! Additionally, please note that SBC requires ALL donors to be masked throughout the donation process, including while waiting outside of a mobile/bus blood drive.

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.
