FISH Study: Neoplastic Interphase FOXO1 (13q14.11) (For Formalin-Fixed Paraffin-Embedded Tissue) (FFPE)

Interphase nuclei fluorescence in-situ hybridization (FISH) break-apart analyses; previous or concurrent conventional cytogenetic workup recommended (where possible)
Monday - Saturday
5 - 14 days

This test is used to diagnose alveolar rhabdomyosarcoma (ARMS).

Specimen Requirements: 
  • Formalin-fixed, paraffin-embedded tissues
  • FFPE-isolated nuclei
  • De-paraffinated, four-micron, slide-mounted tissue sections

The identification of tissues/cells to be targeted and DNA probe selection is the responsibility of the requesting or submitting parties.

Tissue sections and tissues utilized to obtain nuclei isolated from paraffin blocks submitted for interphase FISH analysis must include concurrent evaluation by qualified individuals utilizing additional non-FISH morphometric features to ensure that the requested FISH test(s) are applied to the appropriate tissues/cells.

Reference Values: 

By report; interpretive

CPT Code (s): 
  • 88367 x 2 (computer-assisted)
