Based on the following serology results: Anti-A 4+, Anti-B 0', Anti-D 4+, RhC 0, A1 Cells 0, B cells 4+, Dolichos biflorus 4+. What is the ABO/Rh group indicated?

This pattern shows the red cells carry A antigen with no B antigen, and the patient is Rh positive. That places the blood group in the A category and Rh positive overall. To tell if this is A1 or A2, the Dolichos biflorus (DB) result is key: a strong DB reaction means the A antigen present is the A1 subtype. The A1 Cells test being negative for anti-A1 antibodies in the patient’s serum supports that there aren’t anti-A1 antibodies present, which is typical for someone who is A1 rather than A2. The B cells showing a reaction in the reverse typing is expected for someone with type A blood, since they have anti-B antibodies in serum. Putting it together, the code for this profile is A1 Rh positive.
