This test detects single-nucleotide and deletion mutations in the EGF receptor (EGFR) gene in exon 18 through exon 21. Although a mutation may be present in the tumor cells, if there is very little tumor tissue and/or when there are insufficient tumor cells present that contain the mutation, the test may result in "no mutation detected" despite the mutation being present in a minority of tumor cells.

To detect EGFR gene mutations in non-small cell lung cancer tumor cells; knowing whether a mutation is present in the cells can help determine if EGFR-targeted tyrosine kinase inhibitors such as gefitinib and erlotinib may be beneficial for treating the tumor. Examples of EGFR-targeted therapy include drugs such as gefitinib and erlotinib, which are small molecules called tyrosine kinase inhibitors (TKIs) that enter cancer cells and impede signaling through the EGFR pathway.
