|This battery can be ordered for clinical scenarios that include serological evaluation for possible clinical hemolysis such as a patient with a decrease in hematocrit that is unexplained by bleeding and supporting laboratory values (LDH, indirect bilirubin, haptoglobin) are suggestive of hemolysis or a patient who is being monitored due to the presence of a red cell autoantibody or a hemolytic anemia.
|Sample will be evaluated by multiple methodologies
|Initial testing consist of direct and indirect antiglobulin tests (DAT, IAT) if the previous testing was non-reactive. The investigation may include an elution with PEG-IAT, antibody identification if required, common phenotyping and in rare cases, red cell separation or RBC genomic testing if evidence of transfused cells is seen in the phenotyping.
