Blood Typing and ABO System Quiz

Study Notes

Universal Donor

Blood group O negative is considered the universal donor.
This is because individuals with O negative blood do not have A, B, or Rh antigens on their red blood cells, making their blood compatible with those of all other blood types.

ABO Blood Group System

The ABO blood group system is determined by the presence or absence of specific antigens on the surface of red blood cells.
Antigens are substances that can trigger an immune response.
There are two primary antigens (A and B) and two blood groups (O and AB) in the ABO system.
Individuals with type A blood have only the A antigen on their red blood cells, while type B individuals have only the B antigen.
Type AB individuals have both A and B antigens, while type O individuals have neither A nor B antigens.

Blood Transfusions for Type AB Individuals

Individuals with type AB blood are considered universal recipients
They can receive blood from all blood types
This is because they have both A and B antigens on their red blood cells and therefore do not produce antibodies against either antigen.

Most Common Blood Type

O positive is the most common blood type in the population.
O negative is the least common blood type.

Rh Factor in Blood Typing

The Rh factor is an antigen found on the surface of red blood cells.
Rh positive (Rh+) individuals possess the Rh antigen, while Rh negative (Rh-) individuals lack it.
Rh factor is a critical factor in blood transfusions and pregnancy.
Rh-negative individuals can develop antibodies against Rh-positive blood if exposed to it, leading to complications.
