Reactions are graded from 0 to 4+.
(A) 4+ reaction is indicated by solid band of red cells on the top of the gel;
(B) 3+ reaction displays agglutinated red cells in the upper half of the gel column;
(C) 2+ reaction is characterized by red cell agglutinates through length of column;
(D) 1+ reaction indicated by RBC agglutinates mainly in lower half of gel column with some unagglutinated red cells pelleted at the bottom;
and
(E) Negative reactions display a pellet at the bottom and no agglutinates in the matrix of the gel column. A mixed field reaction may be observed.
