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 CD19, CD20, CD38, CD45, CD56, CD117, CD138, cKappa, and cLambda (9 markers).

Clinical Significance

Useful for diagnosis of multiple myeloma and other plasma cell dyscrasias. Normal plasma cells express a polyclonal pattern of kappa and lambda immunoglobulin (Ig) light chains. Clonal expression of either kappa or lambda light chains indicates an expansion of a clone of plasma cells and is consistent with a plasma cell dyscrasia.

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. Refrigerate specimen. Do not freeze. Use cold pack for transport, making sure cold pack is not in direct contact with specimen.
