In plain language
What this test helps you understand
This test utilizes the Fluorescence In Situ Hybridization (FISH) method. FISH uses fluorescent probes that bind to specific parts of a chromosome. This allows scientists to visualize and detect genetic changes, including rearrangements, within cells. The results provide valuable information for oncologists to determine the most effective treatment strategies for patients. Understanding the genetic profile of a tumor can lead to more personalized and targeted therapies.
This test is typically considered for patients diagnosed with certain types of cancer or those suspected of having a cancer associated with NTRK3 rearrangements. It is often used as part of a comprehensive diagnostic workup to guide treatment decisions. Discussing your specific situation with your oncologist is crucial to determine if this test is appropriate for you.
