Test Code
MYEREF
CPT Codes
88271 (x4), 88275 (x2) for the FISH, Myeloma, 17p-, rea 14q32 component<br /> 88271 (x7), 88275 (x3) for the FISH, Myeloma, Risk Assessment Panel component
Includes
FISH, Myeloma, 17p-, rea 14q32 and FISH, Myeloma, Risk Assessment Panel
When the result for IGH rearrangement is positive during initial FISH analysis, the IGH Panel (MAFB, MAF, FGFR3, CCND1) will be performed at an additional charge (CPT code(s): 88271 (x8), 88275 (x4)).
This allows identification of high risk t(14;16) and t(14;20), intermediate risk t(4;14), and standard risk t(11;14).
Please note: Partial reports are issued when the sample is insufficient to perform all components of the FISH panel.

Clinical Significance
Plasma cell myeloma (PCM) is characterized by the proliferation of malignant monoclonal plasma cells in the bone marrow. Initial FISH testing is performed to detect high risk rearrangements of IGH (14q32) and deletion of TP53 (17p13.1). The prognostic panel also includes probes to detect gains of 1q and monosomy or deletion 13q associated with less favorable outcome and gains of chromosome 9, 11, and 15 associated with more favorable outcome.
