During a double red cell donation, your blood is separated into its components during the donation process and the platelets and plasma portion are returned to you. This means that it’s missing those things that could cause a bad reaction during a blood transfusion and can be given to any blood type. O negative blood is missing both the A antigen and the B antigen and does not contain the protein for Rh positive blood. Some donors may qualify for double red cell donations. This gives us the common blood types of A+, A-, B+, B-, AB+, AB-, O+ and of course O. That’s the type of donation you’ll find on most bloodmobiles.ĭuring whole blood donation, a pint of blood is taken from the donor and then later separated into its components – red blood cells, platelets and plasma. Rh-negative blood types make up about 10-15 of the population, leaving scientists scratching their heads at the question: Where the heck did this blood type originate. It can also be written A+ and O-, respectively. The blood is thus tagged as being A positive, O negative for instance, where the letter refers to the ABO blood group and 'positive' or 'negative' refers to whether or not the RhD-antigen of the Rhesus blood group system was found. You’re probably familiar with whole blood donation. Group O (with no antigens) has anti-A and anti-B antibodies. So, yes, we want your blood donation, we need it. These include antisocial personality disorders, panic disorders and attention deficit hyperactivity disorder (ADHD).
Here are some strange facts about Rh-negative blood: People with Rh- groups have a higher risk of developing mental health issues. When someone with O Negative blood has an accident or undergoes surgery, they must receive an O- transfusion. Although individual categories of Rh- groups have different characteristics, they share a few. But it is also the only blood type that can save O Negative recipients. This results in having them being more picky when it comes to food preferences. O Negative blood can help save any and all trauma patients, premature babies, and cancer patients. People with the Rh negative blood type are more prone to be affected by allergies, especially food allergies. In fact, O Negative blood is often used for premature infants and babies who need blood transfusions. Once doctors determine the patient’s blood type, they can switch to that type of blood.īut even then, O- blood is still an option. It is estimated 7 percent of the population has O- blood type while only 1% of the population has AB- blood.īut because the red blood cells of O- blood donors can be transfused into patients with any blood type, it is often the first choice for transfusions necessary in trauma situations. Myth: O Negative blood is the rarest blood typeĬontrary to popular belief, O- blood is not the rarest blood type.
