Multiple Myeloma Panel by FISH
Ordering Recommendation
Aids in risk stratification of individuals with plasma cell neoplasms (monoclonal gammopathy of unknown significance [MGUS], smoldering multiple myeloma [SMM], multiple myeloma [MM]). Recommended at initial diagnosis and/or at disease progression. Refer to companion test FISH, Interphase, CD138+ Cells (3002737) for custom FISH probe ordering to monitor for a previously identified clone.
New York DOH Approval Status
Specimen Required
Nondiluted bone marrow collected in a heparinized syringe. Also acceptable: whole blood collected in green (sodium heparin).
Transfer 3 mL bone marrow to a green (sodium heparin) (Min: 1 mL). OR transport 5 mL whole blood (green, sodium heparin) (Min: 2 mL).
Additional specimen (recommend 2 mL) is required if concurrent testing (chromosome analysis and/or genomic microarray) is ordered due to the need to perform CD138+ cell enrichment process.
Room temperature.
Frozen specimens. Paraffin-embedded specimens. Clotted specimens.
Ambient: 48 hours; Refrigerated: 48 hours; Frozen: Unacceptable

Note
Fluorescence in situ hybridization (FISH) panel is performed on CD138+ enriched cells (assuming specimen is sufficient for enrichment) for multiple myeloma prognosis-specific genomic abnormalities: 1p (CDKN2C loss/deletion)/1q (CKS1B gain/amplification), 17p (TP53 loss/deletion)/ 17q (NF1) control, t(4;14) (IGH/FGFR3 or NSD2 (MMSET) fusion), t(11;14) (IGH/CCND1 fusion and/or +11), t(14;16) (IGH/MAF fusion), t(14;20) (IGH/MAFB fusion).
When this test is ordered in conjunction with a chromosome analysis, and/or genomic microarray, specimen prioritization for low cellularity samples will be given to FISH>microarray>karyotype due to the need for CD138+ cell enrichment prior to FISH and microarray testing. This could impact successful completion of lower priority tests.
If enrichment fails to yield sufficient CD138+ cells, testing will be performed using unenriched cells, if available.
A processing fee will be charged if this procedure is canceled at the client's request, after the test has been set up, or if the specimen integrity is inadequate to allow a complete analysis.
This test must be ordered using Oncology test request form #43099 or through your ARUP interface.
Contact ARUP Genetics Processing for other specimen types or information and specific collection and transportation instructions.
