All FISH Panel

This panel runs three targeted FISH tests together to check for genetic abnormalities commonly seen in acute lymphoblastic leukemia, without including a full chromosome karyotype alongside them. The probes look for BCR/ABL translocation at chromosomes 9 and 22, MLL rearrangement at 11q23, and TEL-AML1 fusion involving chromosomes 12 and 21, three of the most clinically significant abnormalities found in ALL. Since FISH works directly on the DNA using fluorescent probes, it can pick up these specific rearrangements quickly and reliably, even in samples where a standard karyotype might not be feasible or where results are needed faster.

Who should get this test done?

This test is recommended for:

●     Individuals newly diagnosed with acute lymphoblastic leukemia needing rapid genetic classification
●     Individuals where a quicker turnaround on key prognostic markers is clinically important
●     Individuals whose sample quality or quantity makes full karyotyping difficult
●     Individuals being risk-stratified specifically based on these three known abnormalities
●     Individuals undergoing follow-up testing to track a previously identified genetic marker
Why consider this test?

Each of these three markers carries real treatment implications on its own, and testing for them together means doctors don’t have to wait on multiple separate orders to get a complete picture. These chromosomal abnormalities function as independent prognostic indicators in ALL, directly shaping how aggressively treatment needs to be approached. FISH also has a particular advantage in catching things that might otherwise slip through, since it’s capable of detecting cryptic rearrangements that don’t show up on conventional karyotyping at all. For a disease where treatment decisions often need to move quickly, having this kind of targeted, faster genetic insight matters quite a bit.

More information

This panel is generally used either as a focused alternative to broader cytogenetic testing or alongside it, depending on what a particular case calls for. Each of the three components reports its own findings independently, covering details like the specimen used, clinical indications behind the request, total cells examined, and the final interpretation, so doctors get a clear breakdown of each marker rather than a single combined result.
