An EGFR mutation test may be ordered by itself or as part of a panel (a series of tests to detect mutations in other genes such as KRAS, ALK and ROS1). Certain mutations called "activating mutations" in the EGFR gene can result in excessive signaling for growth and uncontrolled proliferation of cancer cells. However, identification of patients who have developed EGFR TKI resistance as a result of the T790M mutation is complicated by several factors. (© 2003).

In addition, blood tests for circulating tumor DNA (ctDNA), also called liquid biopsies, may be done to detect EGFR mutations in the tumor that can predict potential responsiveness or resistance to targeted therapies. If no sensitizing mutation is detected by the EGFR test, then the tumor is less likely to respond to TKI therapy.
