Fortress A Subgroup + (Blood Grouping Gel Cards)

Fortress A Subgroup + (Blood Grouping Gel Cards)

This test allows the detection of A1 and H antigen in gel technique.

The two main subgroups of A are A1 and A2. Red cells of both react strongly with anti A reagents. The serologic distinction between A1 and A2 is based on results obtained in tests with reagent anti-A1, the lectin of Dolichos biflorus seeds.
Anti-A1 reagents agglutinate A1 but not A2 red cells.
