Useful For Suggests clinical disorders or settings where the test may be helpful

Detecting a neoplastic clone associated with the common chromosome abnormalities seen in patients with various T-cell lymphomas

 

Tracking known chromosome abnormalities and response to therapy in patients with T-cell lymphomas

Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

This test does not include a pathology consultation. If a pathology consultation is requested, 70012 / Pathology Consultation should be ordered and the appropriate FISH test will be ordered and performed at an additional charge. Mayo Hematopathology Consultants are involved in both the pre-analytic (tissue adequacy and probe selection, when applicable) and post-analytic (interpretation of FISH results in context of specific case, when applicable) phases.

 

This test includes a charge for application of the first probe set (2 FISH probes) and professional interpretation of results.

Additional charges will be incurred for all reflex probes performed. Analysis charges will be incurred based on the number of cells analyzed per probe set. If no cells are available for analysis, no analysis charges will be incurred.

 

Depending on the lymphoma subtype suspected, the most appropriate probes to order are listed in the Clinical Information.

 

If the patient is being tracked for known abnormalities, indicate which probes should be used.

Panel includes testing for the following abnormalities using the probes listed:

14q32.1 rearrangement, TCL1A

-7/7q-/i(7q), D7S486/D7Z1

+8, D8Z2/MYC

2p23.2 rearrangement, ALK

 

This assay detects chromosome abnormalities observed in paraffin-embedded tissue samples of patients with T-cell lymphoma. For testing the blood and bone marrow from patients with T-cell lymphoma, see TLPF / T-Cell Lymphoma, FISH, Blood or Bone Marrow.
