The preferred specimen type is bone marrow. Immunophenotyping may be performed on peripheral blood (EDTA) if there is a large number of Blast cells (population of interest) present. Bone Marrow smears submitted to the lab will be used for assessing cell morphology only; immunophenotyping cannot be performed on bone marrow smears. Call 614-722-5482 for more information about sample sources and additional markers. Result will include pathologist interpretation. Reflexive testing may include Cytochemical stains (CPT 88319 x number of stains ordered), Iron stain (CPT 85536), and/or additional Surface or Intracellular markers (CPT 88185) ordered by the Pathologist for confirmation of diagnosis. A Pathologist's interpretation (billed from Pediatric Pathology Associates (PPAC)) will be ordered and charged to the patient.
