Interpretive Data

Compliance Category

Analyte Specific Reagent (ASR)

Note

Fluorescence in situ hybridization (FISH) is performed on CD138+ sorted cells (assuming specimen is sufficient for sorting) for multiple myeloma prognosis-specific genomic abnormalities. The comprehensive multiple myeloma panel is available under mnemonic FISHMMP (3002063). The following probes may be ordered individually or in any combination: 1q (CKS1B) gain/amplification/17p (TP53) loss/deletion, t(4;14) (IGH/FGFR3 and MMSET fusion), 8q (MYC) break apart, t(8;14) (IGH/MYC fusion), +9/9p (JAK2) trisomy/gain, t(11;14) (IGH/CCND1 fusion and/or +11), 13q (D13S319) deletion, 14q (IGH) break apart, t(14;16) (IGH/MAF fusion), t(14;20) (IGH/MAFB fusion), +15/15q,+17/17q (PML/RARA gain).

When this test is ordered in conjunction with a chromosome analysis, specimen prioritization will be given to FISH for the sorting of CD138+ cells. This could impact the successful completion of the chromosome analysis.

If sorting fails to yield sufficient CD138+ cells, testing will be performed using unsorted cells, if available.

If more than one probe is ordered, additional charges will apply.

Contact ARUP Genetics Processing (extension 3301) to add a probe to a current specimen.

Other specimen types may be acceptable, contact Genetics Processing (extension 3301) for specific specimen collection and transportation instructions.

This test must be ordered using Oncology test request form #43099 or through your ARUP interface.
