Study Notes
Blood Group Antigens
- ABO blood group antigens are located on red blood cell membranes.
- Type O blood is the universal donor due to the absence of A and B antigens.
- Type AB blood is the universal recipient since it has both A and B antigens, allowing it to accept all blood types.
Rh Factor
- Approximately 85% of Americans have the D antigen, indicating they are Rh-positive.
- Hemolytic disease of the newborn (HDN) concerns arise when an Rh-negative mother carries an Rh-positive fetus.
Blood Type Characteristics
- Blood Type A:
- Antigens: A
- Antibodies: Anti-B
- Preferred Donor: A, O
- Incompatible: B, AB
- Prevalence: 40% in the USA
- Blood Type B:
- Antigens: B
- Antibodies: Anti-A
- Preferred Donor: B, O
- Incompatible: A, AB
- Prevalence: 10% in the USA
- Blood Type AB:
- Antigens: A & B
- Antibodies: none
- Preferred Donor: AB, O, A, B
- Incompatible: none
- Prevalence: 4% in the USA
- Blood Type O:
- Antigens: neither A nor B
- Antibodies: both Anti-A and Anti-B
- Preferred Donor: O
- Incompatible: A, B, AB
- Prevalence: 46% in the USA
Blood Typing Process
- Blood typing identifies antigens using blood samples mixed with typing sera containing known antibodies.
- Agglutination occurs when a specific antibody interacts with its corresponding antigen, causing red blood cells to clump.
- Cross-matching tests check compatibility by mixing small blood samples from donor and recipient to prevent transfusion reactions.
True/False Statements
- Type B is not the most common blood type in the US; Type O is.
- Individuals with blood type O lack both A and B antigens.
