Definition

Noun A system for classifying human blood based on the presence or absence of inherited antigenic substances (A and B) on the surface of red blood cells. This system is fundamental to blood transfusion safety and compatibility, defining four main blood types: A, B, AB, and O.

Usage

The term is used primarily in medical, biological, and transfusion contexts to denote the blood group system itself or to specify an individual's blood type within that system. - The patient's ABO group was determined to be O-positive before the surgery. - Compatibility of the ABO group between donor and recipient is critical to prevent a transfusion reaction.

Advanced Usage
  • ABO grouping: The process of testing to determine an individual's ABO blood type.
    • The laboratory performed ABO grouping and Rh typing on the sample.
  • ABO incompatibility: A condition where the donor and recipient blood types are not compatible within the ABO system.
    • The transfusion was halted due to a risk of ABO incompatibility.
Variants and Related Words
  • ABO blood group: A more explicit, full form of the term.
  • ABO system: A synonymous term emphasizing it as a classification system.
  • Blood type: A common, more general term for an individual's classification (e.g., Type A), which is determined by the ABO group and the Rh factor.
Synonyms
  • Blood group system (specific to ABO)
  • ABO blood type system
Notes

The ABO group is the most significant blood group system for blood transfusions. The "O" in the group represents the absence of both A and B antigens. Knowledge of both the ABO group and the Rh factor (positive or negative) is required for safe blood transfusion and is crucial in organ transplantation and prenatal care.

Noun
  1. a classification system for the antigens of human blood; used in blood transfusion therapy; four groups are A and B and AB and O
