0: Negative; 1+: Most of the agglutinated red blood cells remained in the lower part of the column, where some red blood cells were visible; 2+: The agglutinated red blood cells were distributed throughout the column, and a small number of cells were visible at the bottom of the column; 3+: Most of the red blood cells that agglutinate remained in the upper part of the glass column; 4+: Red blood cells agglutinated above the column and formed a ring band.

The antigens of the Duffy blood group are named after the last two letters of Duffy: Fy, and there are two main antigens: Fy^a and Fy^b; Le^a and Le^b are two of the six antigens in the Lewis blood group system.
