Reading and Interpreting Results
The Genebio ALK/EML4 TriCheck™ Probe yields distinct fluorescence signals that delineate the ALK gene, EML4 gene, and their fusion product. Careful scrutiny under a fluorescence microscope can reveal the presence or absence of genetic aberrations.
Each fluorescent signal corresponds to a specific genetic component: green for EML4, red for ALK, and a fusion signal typically seen in yellow. The separation or co-localization of these signals is pivotal in interpretation.
It is crucial to differentiate between discrete signals and their co-localized fusion, as this determines the outcome of ALK-EML4 status. A solitary signal for ALK or EML4, or the absence of a fusion signal, indicates a negative result for the ALK-EML4 gene fusion.
Interpreters must exercise diligent analysis, as the presence of both EML4 and ALK signals in juxtaposition or overlapping suggests a positive result for the gene fusion. A lack of one or both signals, or the failure to detect a fusion, necessitates reevaluation or repetition of the test. In clinical diagnostics, false negatives can have significant implications; hence, adherence to rigorous analytical standards is essential.
