What Does The Term Donor Deferral Mean

Donor deferral means that an individual is not eligible to donate based on the current requirements. This waiting period is necessary to protect the health and safety of both the donor and the patient who receives the donated blood.

In the United States, blood collectors follow donor eligibility criteria based on requirements of the Food and Drug Administration, AABB Standards, and their own local policies. The medical director of the blood donor center has ultimate authority to establish a more stringent deferral policy based on their clinical judgement as a physician.

The period of time a person will not be eligible to donate depends on the specific reason for deferral. After the deferral period ends, a donor can return to the blood donor center to be reevaluated and resume donation if all donor eligibility criteria are met.

AABBs donor deferral resource explains some of the most common reasons for deferral. Contact your local blood collector for specific questions about your eligibility.

Why Is Blood Type Important

Blood type is determined by the presence or absence of two antigens found on the surface of red blood cells. These antigens are labeled A and B, along with a protein known as the Rh factor. The presence or absence of this protein determines if a person’s blood type is positive or negative. The six blood types with either the A or B antigens are A+, A-, B+, B-, AB+, and AB-. Blood types that have neither antigen are type O and are classified as either O+ or O-. Type O negative blood is a universal blood type, meaning that it can be given to any recipient. Type O negative is in high demand at hospitals .

Given that there are eight different blood types, it’s crucial that a patient be paired with their matching type . If you receive blood that has different antigens, your body’s immune system will attack the donor cells with antibodies. This is what is known as a hemolytic transfusion reaction, or an ABO incompatibility reaction, and it can be serious .

If you receive the wrong blood, chances are that you’ll know fairly quickly. Symptoms include fever, chills, difficulty breathing, and nausea. Upon detecting a reaction, the medical staff will stop the transfusion and attach a saline drip to try and prevent stroke, kidney failure, or blood clotting .

Whats The Recovery Time After Donating Blood

In the United States, the recommended recovery time is a mere eight weeks. But this is not the same all over the world. For example, if youre donating from the UK, you get double that amount of time its recommended you only give blood in 12-16-week intervals.

Whys there such a large discrepancy between recovery times? The experts are trying to figure that out as well. For example, to determine whether or not the UK standard is worth following, researcher Edward Murphy embarked on a study that analyzed the gaps in international transfusion standards.

The study was conducted for over two years and had a subject pool of about 45,000 blood donors. Recovery periods were different for men and women, with some subjects getting up to 12 weeks and other only 8. By the end, over a quarter of the regular donors reported having experienced side-effects and were confirmed to have developed iron deficiency.

However, despite such findings, the research team reported their results to suggest that frequent donations, like the ones seen in America are acceptable. A sensible approach has to be taken by donors. If you dont feel comfortable with shorter recovery times, or experience side effects after donating blood, leave a significant time lapse between donations.
