The Lewis blood group system is a human blood group system, classified by the expression of glyocoproteins called Lewis (LE) antigens. Lewis antigens are synthesized by intestinal epithelial cells, circulate in plasma and are passively absorbed onto red blood cells. Antibodies to the Lewis antigen are generally IgM.

Fortress Diagnostics manufacture Anti LE and Anti-LEb  blood grouping reagents for the in vitro detection and identification of the human LEand LEblood group antigens by direct agglutination.
