GEL column card with two analyzed samples. The sample labeled G13/12 was type B blood as the agglutination occurred only in the B column; sample G27/15 was type A as agglutination occurred only in the A column. Both reactions were graded 4+ as all the RBCs were agglutinated and formed a layer at the top of the gel column. Control columns (c) containing PBS only are included and show absence of autoagglutination.
