Testing Algorithm
The following tests may be ordered and performed (at an additional charge) as needed for antibody identification: direct antiglobulin testing (polyspecific), including its reflex tests and special red blood cell antigen typing.
If certain antibodies are detected and the patient is known to be pregnant, an antibody titration will be performed at an additional charge.
