Blood group antigens are defined by ____ attached to glycoprotein or glycolipid structures or by amino acids on a protein.
carbohydrates
The symbol used to indicate the presence or absence of letter antigens.
Plus sign (+) for present, minus sign (-) for absent
The notation format for antigens with superscripts.
Superscript letter placed in parentheses, e.g., Fy(a+), Jk(a–)
The format when testing for antithetical antigens.
Both results within parentheses, e.g., Fy(a–b+)
The notation format for antigens with numerical designations.
System letter(s), colon, antigen number; minus sign for absence, e.g., Sc:–1,2
Format for phenotypes of multiple blood group systems.
Phenotypes separated by semicolons, e.g., S+s+; K–; Fy(a+b–)
Notation for antibodies against antigens.
Anti- followed by antigen symbol, e.g., anti-Fy(a)
Serologic tests determine this aspect of RBCs.
RBC phenotype only, not genotype
The method to determine RBC genotype.

First three digits: system, collection, or series; Second three digits: antigen
Definition of a blood group system.
One or more antigens controlled at a single gene locus or by closely linked homologous genes with minimal recombination
Definition of a blood group collection.
Antigens with biochemical, serologic, or genetic relationships not meeting system criteria
Cataloging method for remaining RBC antigens not in a system or collection.
700 series for low prevalence, 901 series for high prevalence
