Blood Donor Requirements
Please Note: This list of Blood Donor Requirements is not complete. Medical professionals are available at each of our Community Blood Centers and bloodmobiles who will discuss and evaluate each donor's health history and activities in a confidential setting prior to blood donation. The final determination of eligibility is made at that time. Certain donor eligibility criteria are specified by the Food and Drug Administration, State of California, American Association of Blood Banks (AABB) and European Union (EU).
The remaining criteria is determined by the Medical Director of the San Diego Blood Bank and may differ among the types of donations and with the criteria from other blood centers. Donor eligibility criteria is intended to protect the health and safety of the donor and the patient who will receive the transfusion.
