Medical History Questionnaire

Prior to completing the medical history questionnaire, donors MUST FIRST READ Blood Donor Educational Material. The questions below will be answered YES or NO. If you are trying to determine your eligibility to donate and answer “yes” to one of the questions (excluding #1 and #5) please call 650-723-7831 to clarify. A “yes” response does not necessarily make you ineligible to donate.

Save Time and Skip the Line!

You may fill out your medical history questionnaire ahead of time on the day of your donation by using SBC preCheck™.

The following is included in the medical history questionnaire:

I certify that I am 17 years of age or older (unless separate consent is signed), and I am voluntarily donating my blood to the Stanford Blood Center for use as it deems advisable. I have read and understood the donor information given to me, the donation process has been explained to me, and all of my questions have been answered to my satisfaction.

I understand that my blood will be tested for evidence of exposure to infectious agents that can be transmitted through transfusion including, but not limited to, hepatitis B and C, HIV (the AIDS virus), HTLV, syphilis, and West Nile Virus. I will be notified of test results that are important to my health or that affect my eligibility to donate. Blood with a positive test result will not be used for transfusion. The Blood Center will retain records of all donors with abnormal test results. I understand that the Blood Center may be required to report certain positive tests to the public health service.

I understand and agree that my blood and stored samples may be used for transfusion, further manufacturing, investigational testing, training, research, and other uses as needed. I also understand and agree that my health information may be used in a confidential manner for blood center operations and research.

I agree not to donate blood or plasma for transfusion to another person or for further manufacture if I know that I am infected with HIV (the AIDS virus), if I have tested positive for HIV or antibody to HIV, or if I believe that I may have been exposed to HIV. I understand that starting 2018 it is a misdemeanor in California for persons to donate blood when they know they have AIDS or have tested positive for HIV or antibodies to HIV.

I understand that the most common side effects of blood donation are bruising at the donation site, light-headedness, and rarely, fainting, inflammation of the vein, infection of the skin, or nerve injury.

I certify that I have read the materials and that I have answered all questions truthfully and to the best of my knowledge, to provide protection for me as a donor and for the safety of the recipient of my blood.
