Note

Fluorescence in situ hybridization (FISH) panel is performed on CD138+ sorted cells (assuming specimen is sufficient for sorting) for multiple myeloma prognosis-specific genomic abnormalities: 1q (CKS1B) gain/amplification/17p (TP53) loss/deletion, t(4;14) (IGH/FGFR3 and MMSET fusion)/+9/9q (ASS1) trisomy/gain, 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, 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.

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.
