Fluorescence in situ Hybridization (FISH), Oncology
Use
Confirmation/identification of leukemia/lymphoma-related alterations; leukemia/lymphoma monitoring of residual disease, transplants, and indolent clones (see list or call lab for probe availability).
Special Instructions
The test is essentially a tracking code; it requires the probe and diagnosis to be provided for testing to commence. Absence of such information will delay the turnaround time. Provide targeted FISH probe and diagnosis with the specimen. Pertinent clinical diagnosis, previous cytogenetic studies, and probe of interest should be included with the submission.
Limitations
The test will not detect molecular mutations or chromosomal alterations not targeted by the probe included in the profile. Testing is performed once the needed probes and diagnosis are received. The FDA has determined that clearance or approval is not necessary for this test, and it should not be regarded as investigational or for research purposes.
