ABO blood typing is used to determine an individual’s blood type (A, B, AB, or O) based on the presence or absence of certain antigens on the surface of red blood cells.

iollo markers that associate with ABO


Choline is an essential nutrient involved in lipid metabolism and cell membrane integrity. As ABO antigens are glycolipids or glycoproteins on the red blood cell surface, altered choline levels and phospholipid metabolism could theoretically impact the expression or structure of ABO antigens.


Glycine is involved in the biosynthesis of heme, a key component of hemoglobin found in red blood cells. The ABO blood group is determined by the presence of specific antigens on red blood cells. Variations in glycine levels could potentially influence heme production and the expression of ABO antigens.
