FISH Study: Neoplastic Interphase MDM2 with D12Z3 (12q15) (For Formalin-Fixed Paraffin-Embedded Tissue) (FFPE)

Additional Information:

UFHPL Test #: 30220

CPT Code(s):

  • 88367 x 2 (computer-assisted)
  • 88368 x 2 (manual)

Collection Procedure:

-

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.

Use:

This test is used to confirm histological discrimination of well-differentiated liposarcoma/atypical lipomatous tumor (WDL/ALT) from lipoma.

Methodology:

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

Reported:

5 - 14 days

Reference Values:

By report; interpretive
