Donate Blood

Blood Donation Assessment Form

Most people can give blood, but before we accept your blood we need to ensure there’s no risk of us harming you or the patients who will receive it. Use the below links to see if you are eligible to give blood and to gain advice on preparing to give blood.

Any other questions or queries please contact us on 042-37422140 & 141 or via the submitting blood assessment form. Fill out a Medical History Questionnaire and discuss answers confidentially with a Medical Historian.

Male donors can give blood after every 12 weeks. That’s approximately every 3 months or 4 times in a 12 month period. Female donors can give every 16 weeks or approximately every 4 months.


Only 38% of the general population are eligible to donate, but fewer than 10% of those eligible actually donate.

Please use the information on this site as a general guide; an evaluation by a medical professional is the only way to determine eligibility.

  • do not skip meals
  • be sure to drink plenty of fluids (water/juices)
  • bring photo identification

Donors must:

  • be at least 17 years of age (by California law, all 16 year olds must have a parent’s or legal guardian’s permission to give a community blood donation by bringing a completed Stanford Blood Center Parental/Guardian consent for 16 year olds form with them to register to donate; this form can be obtained at a Stanford Blood Center donor center, Stanford Blood Center community blood drive, or from your high school blood drive coordinator)
  • weigh at least 110 pounds for donors 19 or older (Donors under 19-see height/weight requirements)
  • be free of cold and flu symptoms (allergies ok; as are most medications)
  • eat before donating and drink plenty of fluids
  • bring photo ID

Because blood is a living tissue that is transplanted into another human, the U.S Food and Drug Administration (FDA), in an attempt to ensure a safe blood supply, has imposed strict controls on who may donate. If you discover that you are not eligible to give blood, you can still save lives by providing blood for research, coordinating a blood drive within your organization, volunteering your time, or contributing financially. However you participate in our programs, you are helping maintain the health of our community. Thank you for your dedication.
