Final answer:
A person with blood cells that react to both A and B antibodies but lack the Rh factor has blood type O negative.
Explanation:
Type AB blood has both A and B antigens on the cell surface and no preformed antibodies. Blood type O lacks A and B antigens but has both anti-A and anti-B antibodies. Therefore, if a person's blood cells react to both A and B antibodies and do not have the Rh factor, their blood type would be O negative.
