EGFR gene mutations tested for

This test identifies specific mutations in the EGFR (epidermal growth factor receptor) gene from blood or tissue samples. EGFR mutations are commonly found in certain lung cancers and can determine which targeted therapies will be most effective. Different mutations respond differently to specific medications called EGFR inhibitors. Testing for EGFR mutations is crucial for cancer patients to guide treatment selection, predict drug response, and optimize outcomes. This genetic information helps oncologists personalize cancer treatment plans.
