Summer of Giving

GLAAD, in partnership with America’s Blood Centers, has kicked off their Summer of Giving campaign, which aims to encourage businesses to host blood drives and all eligible individuals to donate blood in recognition of recent eligibility changes that promote fairness and inclusivity in the donation process while maintaining the safety of the blood supply.

Stanford Blood Center implemented the new FDA guidance that expands blood donor eligibility to more LGBTQIA+ community members in October of 2023, and is a proud to support this awareness campaign. Learn more about the eligibility changes here, and please help us spread the word by following us on social media for updates!

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.

  • 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.
