AB negative can provide to AB neg or pos
You can receive blood from just about anybody
A,B,O, or AB
the blood you receive should be neg. You can under extreme conditions receive positive blood once. After that the likelihood of your developing an Rh antibody go up. This is what happens to Rh neg mothers with Rh pos children - A bleed from the child exposes the mother to Rh pos antigens and the body develops antibodies. The subsequent Rh pos child has problems. Fortunately, they have developed preventive treatments for this problem (i.e. Rhogam - not to be confused with the spine gel).
You mentioned that your A antigen is A1. This comprises about 80+% or so of A antigens. It should not comprise any problems for you( or any receiving your blood in a majority of cases) Consider the A antigen as a branch beside twigs. The other subgroups are missing twigs. Since the body cannot recognize something not there as foreign it will not react.
Now for the most critical thing!! - when donating be sure to place blood coverage on yourself and those you care about. This help should blood be needed because of an emergency. Source(s): Med Tech
