Blood Donation: How It Works

Preparing to donate

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:

  • 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.
