Anti-FYb

The FY^a and FY^b antigens were reported in 1950 and 1951 respectively. Anti-FY^b has been implemented in immediate and delayed Haemolytic Transfusion reactions and Haemolytic Disease in the new born. Indirect agglutination of red cells that carry the FY^b – antigen occurs in the antiglobulin phase.  In the absence of the FY^b– antigen, no indirect agglutination is generally observed.

The Biorex Diagnostics Anti-FY^B reagent consists of human serum diluted in sodium chloride solution containing macromolecular potentiators and bovine albumin. The reagent requires no further dilution or addition for recommended techniques.
