The Kidd antigen system (also known as Jk antigen) are proteins found in the Kidd’s blood group, which act as antigens, i.e., they have the ability to produce antibodies under certain circumstances. The Jk antigen is found on a protein responsible for urea transport in the red blood cells and the kidney.

For these reasons, Kidd antibodies are responsible for about one-third of all delayed HTRs, which may be severe. The antibodies are mainly IgG but can be partially IgM. Kidd antibodies rarely cause HDFN, and when they do, it is generally not severe. Anti-Jk3 can be produced by Jk(a–b–) individuals.
