Immunophenotyping
Clinical and Interpretive info
This test will be processed as a laboratory consultation. An interpretation of the immunophenotypic findings and correlation with the morphologic features will be provided by a hematopathologist for every case.
This test is only appropriate for patients who have a previous confirmed diagnosis of B-cell lymphoblastic leukemia.
Treatment with antibodies to CD19 may interfere with the ability to detect minimal residual disease (MRD).
