Suggestions have been made that women of child-bearing age or young girls should not be given a transfusion with Kell1 positive blood. Donated blood is not currently screened (in the U.S.A.) for the Kell blood group antigens as it is not considered cost effective at this time. It has been hypothesized that IgG anti-Kell1 antibody injections would prevent sensitization to RBC surface Kell1 antigens in a similar way that IgG anti-D antibodies (Rho(D) Immune Globulin) are used to prevent Rh<unk> , but the methods for IgG anti-Kell 1 antibodies have not been developed at the present time.
