What should be done if the antibody screen is positive?
If the antibody screen is positive, in most cases the next step would be to perform antibody identification. If the screen is negative, there is a very high likelihood that no significant antibodies are present (though some rare antibodies against low-incidence RBC antigens could still be present).
