B-Cell Lymphoma, Specified FISH, Varies
Use
This test is useful for detecting common chromosome abnormalities associated with specific B-cell lymphoma subtypes using client-specified fluorescence in situ hybridization (FISH) probes. It assists in the diagnosis and prognosis of mature B-cell lymphomas by identifying recurrent gene rearrangements, serving as important prognostic markers.
Special Instructions
Not provided.
Limitations
The test is not approved by the US Food and Drug Administration and should be used as an adjunct to clinical and pathologic information. If no FISH signals are observed post-hybridization, the case will be released with a lack of FISH results. The absence of an abnormal clone does not rule out the presence of lymphoma or another neoplastic disorder.
