Clinical Utility

Immunophenotyping by flow cytometry distinguishes among various hematopoietic cell populations and determines the degree of expression of a panel of cell surface antigens. The test is used along with morphologic, cytogenetic, and molecular genetic analysis in the identification/classification of hematopoietic neoplasms (leukemia, lymphoma, myelodysplastic disorders, etc.).
Specimen and Container Info

Transport to the laboratory refrigerated.
Stability Requirements

Refrigerated

72 hours
Causes for Rejection
  • Frozen specimens
  • Fixed specimens
