Prenatal Antibody Identification (includes antibody titration, if indicated)
| Indications | This battery can be ordered for any pregnant patient who has not had an antibody screen performed during the current pregnancy or has been found to have a positive antibody screen. If the antibody screen test is reactive, antibody identification will be performed until all common exclusions are completed. |
| Method | Red cell antibody identification by multiple methologies |
| Test Information | This battery of tests could include ABO and D typing, complete phenotyping, antibody titration (one per specificity unless all antibodies are in Rh system), Alloadsorption or adsorption for specificity separation, and plasma/substance inhibitions. If a titer is performed, the remaining sample will be frozen for use as a parallel control to be tested with future samples. Depending on the complexity of the case and number of antibodies identified, further testing may be required. |
