NOT SURE IF YOU ARE ELIGIBLE TO DONATE BLOOD?

California law requires anyone under the age of 17 to have a parent’s or legal guardian’s permission to donate. Donors under the age of 17 should bring the completed consent form (05-FX1) when registering to donate. The consent form can be obtained online here, 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)

- eat before donating and drink plenty of fluids
- bring photo ID
- fill out a Medical History Questionnaire (which will be provided at the time of your donation) and discuss answers confidentially with a Medical Historian
