  • You are completing iScreen on the same day as your donation, no earlier than 1:00 a.m.
    (note: if iScreen is completed on a day other then your donation, you will need to complete iScreen again at your blood drive or blood donation center)
  • You have a computer, laptop, tablet or smart phone.

Possible Reasons For Deferral

As you complete iScreen please be aware:

  1. If you take aspirin or medication after you indicated “no” on your iScreen, you will need to retake iScreen once you arrive for your donation.
  2. There is specific information that may make you ineligible to donate at this time. For example:
    • Donors who received a tattoo within the last year
    • Travel outside the country requires individual evaluation for possible exposure to infectious diseases such as Mad Cow Disease (vCJD), Malaria, Zika, Ebola and/or HIV/AIDS.

  3. Make sure that you are connected to a laser printer or that you have a smart phone.
  4. Complete the Donor History Questionnaire. If there is a question you do not understand or don’t know how to answer, skip it and we will discuss it with you at your donation appointment.
  5. An iScreen Ticket will be generated with a secure bar code. The information secured on this bar code can only be retrieved at a Miller-Keystone Blood Center donation center or blood drive.
