Testing Algorithm
If the antibody screen is positive, then antibody identification will be performed at an additional charge.
If the patient has previously tested positive for antibodies, antibody identification may be performed instead of the antibody screen. If antibodies or an interfering substance (eg, rouleaux, positive auto control) are detected, the antibody screen will be canceled, and the antibody identification will be performed.
If certain antibodies are detected and the patient is known to be pregnant, antibody titration will be performed at an additional charge.
