Flow Cytometry
Test Description

Available as global and tech-only. This add-on panel is available to clarify findings on samples currently having flow cytometry analysis at NeoGenomics and is not available for stand-alone testing. Markers are CD3, CD4, CD7, CD8, CD16, CD45, CD56, CD57, TCR alpha/beta, and TCR gamma/delta (10 markers).

Clinical Significance

This panel differentiates gamma/delta from alpha/beta T cells and evaluates aberrant immunophenotypic expression of LGLs and NK cells. CD1a and CD30 can be added for specific cases.

Specimen Requirements

Flow cytometry testing can be performed on bone marrow aspirate, peripheral blood, fresh bone marrow core biopsy, unfixed tissue, and body fluids. Please see full specimen requirements for either Standard Leukemia/Lymphoma Analysis or Extended Leukemia/Lymphoma Analysis as this add-on panel is available in combination with either of those full panels.

Storage and Transportation

Specimens should be received at NeoGenomics within 72 hours from collection to assure sample integrity and acceptable cell viability. Note: New York State samples must be received within 48 hours from collection per NYS requirements. Refrigerate specimen. Do not freeze. Use cold pack for transport, making sure cold pack is not in direct contact with specimen.
