Why is testing for Rh antigens and antibodies different from ABO testing?
abo blood group system was discovered in 1901 and rh was discovered in 1940.
How does the Rh factor differ from A B and O antigens?
The Rh factor exhibits normal dominant/recessive patterns. In contrast, the ABO antigens express codominance.
Where are the antigens of the ABO blood group are located?
They are found on the cell membrane of every cell, and help to distingish 'self' cells from 'non self' cells
What is the difference between rh incompatibility and abo incompatibility if any?
between ABO and Rh incompatibility
Which antibody and antigen combination match each blood type?
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Can you have a negative red blood cell?
When we classify blood cells by their antigens we can classify them according to the ABO blood groups or the Rh blood groups. The Rh will either be + or -. They are usually used in conjunction so you might be A pos or O neg.
What does Rh positive blood mean and how is it differerent to RH negative blood?
Your blood type is determined (genetically) by the presence or absence of specific surface antigens on the membrane of the RBC. The most important RBC surface antigens are A, B and Rh.Blood can be either Rh positive(Rh+) or Rh negative (Rh-) depending on the presence (Rh+) or absence of the Rh antigen (Rh-) on the surface of the cell.Unlike the ABO system, type Rh- blood does not normally carry anti-Rh antibodies, unless the individual has been sensitized by previous exposure (usually pregnancy).The most common blood type is O+.
Where are the blood antigens A B Rh located?
The blood antigens A, B, and Rh are located on the membrane of the red blood cell. These antigens are hereditary.
What Rh blood type develops the Rh antibody?
The significant Rh antigen most care about is D antigen and all A+, B+, AB+ or O+ blood types have the Rh Antigen. The positive is used to indicate the D antigen. There are different, in fact numerous kind of blood groups. While the ABO blood group is one example the Rh blood group is another one. The Rh blood group has 5 antigens: D C c E & e. Everyone has Rh antigens one or the other but out of Rh antigens the most important one is D. If a person has D anitgen then he/she is said to be Rh+ if not Rh-.
A person who is B positive will have?
B antigens, antibodies to A, and Rh antigens
When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood this is known as?
When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood, this is known as red blood cell incompatibility. Patients should receive blood with the same ABO and Rh(D) classification. A and B are dissimilar antigens on the red cells. The immune system recognizes antigens as foreign. O cells do not have A or B antigens.
Of the antigens in the rh group?
The most important Rh antigen is the D antigen.
