Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

The initial test performed is an antibody identification. If the antibody problem identified is not relevant in hemolytic disease of the newborn, or if titrations are not helpful, the titer will be cancelled and will be replaced by the antibody identification test. Depending upon the antibody identification results, additional tests, ie, monospecific direct Coombs, antibody elution, antibody absorption, and red cell antigen typing may be added and charged. A consultation service is offered, at no charge, regarding the clinical relevance of red cell antibodies.
