Donors who present and testing indicates a low iron result, you will not be eligible to donate blood. We understand that rescheduling can be frustrating, but your health and safety is a top priority. Low iron is one of the most common reasons for a blood-donation deferral. When your iron is low, donating blood will cause your levels to drop even further, leaving you feeling tired and faint. It also affects your ability to generate new red blood cells and can cause a longer recovery time. Eating many types of red meat, fortified cereal, and leafy green vegetables may help.Find out more about low iron and blood donations here

Most localized skin cancers are not a reason to stop you from donating blood. Because many different types of cancer exist, we will ask you a few questions regarding your diagnosis, and in some cases the blood center medical director may make the final determination on the deferral. Most often, people who are free of relapse a year after completion of treatment are able to donate blood.

The U.S. Food & Drug Administration (FDA) has implemented regulations to protect the blood supply against the risk of mad cow disease, variant Creutzfeldt- Jacob Disease (vCJD), a fatal infection of the brain and nerve tissue. Currently, blood donors are indefinitely deferred if: 

  • 3 months cumulative time spent in the U.K. (i.e., England, Northern Ireland, Scotland, Wales, the Isle of Man, the Channel Islands, Gibraltar, or the Falkland Islands) including military service between 1980 to 1996.
  • 5 years cumulative time spent in France or Ireland from 1980 to 2001. Note that this assessment does not include time spent in the U.K, which is evaluated separately.
  • History of ever receiving a blood transfusion in the U.K. (i.e., England, Northern Ireland, Scotland, Wales, the Isle of Man, the Channel Islands, Gibraltar, or the Falkland Islands), France, or Ireland from 1980 to the present.

Please call our Donor Advocacy department at 888-936-6283 extension 33858, if you have previously been: 

  • Deferred for 5 years of cumulative time in Europe other than in France or Ireland
  • Deferred for military service in Europe outside of France, Ireland or UK (i.e., England, Northern Ireland, Scotland, Wales, the Isle of Man, the Channel Islands, Gibraltar, or the Falkland Islands)

People who travel to countries where malaria is endemic will be deferred from donating blood for three months upon returning to the United States.

Donors are required to feel well at the time of the blood donation, so a cold, flu, or allergies may temporarily prevent someone from donating blood. Donors must wait at least 24 hours for many minor surgeries, including dental work. Donors should rely on our screening process to determine surgery or illness deferrals. Many times the blood center medical director may make this determination.

Pregnant women are not eligible to donate blood, but they become eligible six weeks after giving birth. Women who are nursing are encouraged to drink plenty of water both before and after donating blood.

Because of a medical condition known TRALI (transfusion-related acute lung injury), blood centers may question women about prior pregnancies. The question is intended to protect the recipient of the donated blood, since pregnancy may cause women to develop antibodies that could harm a recipient patient.

The blood center is heavily regulated and mandated by the Food and Drug Administration (FDA). As such, each donor must meet certain eligibility requirements in order to donate blood. If a donor does not meet one or more of the eligibility requirements they would be deferred from donating blood that day. 

It depends on the reason you were deferred. Some deferrals are temporary and others are permanent. For example, if a donor’s iron count is too low they would be temporarily deferred until they are able to get their iron levels into the necessary range by eating iron rich foods
