TYPE O NEGATIVE RYM PLUS
So, where do those plus and minus signs come in? Blood types can also be either negative or positive, depending on whether you have another antigen, the Rh(D) antigen. Type O blood has neither A nor B antigens.Type AB blood has both A and B antigens.The four major blood types indicate whether you have A or B antigens - or both or neither. “For example, a Type A individual has anti-B, and must not receive Type B blood.” “Additionally, with the ABO blood group, you have pre-formed antibodies against the missing antigen on your red blood cells,” Dr. This means that if you were to receive a blood transfusion of a type of blood with different antigens than your own blood, your body’s immune system could start to attack itself, which can be deadly. “They can also react with antibodies already formed,” adds clinical pathologist NurJehan Quraishy, MD. Your blood type is dependent on whether you have A and B antigens (from the ABO blood group), and the Rh(D) antigen (from the Rh blood group). There are eight common blood types, and what type you have depends on whether or not your blood includes certain antigens, or substances that can make your immune system react. He explains what it means to be a universal blood donor and why it’s so critical to donate blood, especially if you’re Type O-negative. “All blood donations are important, as they can be life-saving,” says emergency medicine physician Baruch Fertel, MD, “but donations of Type O-negative blood are especially vital.” But in emergencies, Type O-negative blood - which only about 7% of individuals have - can be given to people of any blood type When your body is in need of a blood transfusion, the best blood type to receive is your own blood type.
