Laboratory Testing

The **Ros1 – Fish Test** is a highly sensitive and reliable fluorescence in situ hybridization (FISH) assay designed for the detection of **ROS1 gene rearrangements** in tumor samples. This test is crucial for identifying patients who may benefit from targeted therapies, particularly in **non-small cell lung cancer (NSCLC)**. Key features include **high specificity and accuracy**, rapid turnaround time, and **direct visualization of gene rearrangements** at the cellular level. Its benefits include **early and precise diagnosis**, enabling personalized treatment decisions and improving patient outcomes. The **unique selling point** of the Ros1 – Fish Test is its **proven clinical utility in guiding targeted therapy selection**, making it an essential tool for oncologists and pathologists in precision medicine.
