How To Group Blood Groups?
can the A + blood type receive blood from type O?
Hi, thanks for asking at HealthReplies.com.
One way to determine blood type is to use the ABO system. Blood type is attached to gene I. Where are alleles A, B and O in gene I.
In blood type A homozygotes, there is A allele attached to gene I, namely IA IA. In blood type A heterozygous, there are A and O alleles attached to gene I, namely IA IO. In blood type B homozygotes, there is a B allele attached to gene I, namely IB IB. In heterozygous blood group B, there are B and O alleles attached to gene I, namely IB IO. In blood type AB, there are alleles A and B attached to gene I, namely IA IB. In blood type O, there is an O allele attached to gene I, namely IO IO.
This blood classification system is very useful for the benefit of transfusion. In people with blood type AB, can receive blood donors from any blood type, but can only donate to blood type AB only. Meanwhile, blood type O can only accept blood donations from blood type O, but can give blood donations to any blood type.
In addition to the ABO system, blood grouping is also done based on Rhesus. There are 2 groupings, namely:
1. Rhesus positive, where on the surface of red blood cells found Rh antigens.
2. Rhesus negative, where on the surface of red blood cells are not found Rh antigens.
In the interest of transfusion, someone who has a Rhesus negative cannot receive a blood transfusion from blood with a positive Rhesus, so one must get a transfusion from blood with Rhesus negative as well. While Rhesus positive blood group, can receive donors from Rhesus positive and negative
So blood type A + can receive blood from blood type O.
Thus hopefully useful.
