A focused test that looks for specific changes in the EGFR gene.

Not a diagnosis and not final medical advice. Must be reviewed by a doctor.
Purpose of the test
- Detect common EGFR mutations.
- Become a screening examination before a wider panel.
Informs decisions
- Categories of EGFR-targeted therapies that are worthy of discussion.
How the test is done
The genetic material from the tumor sample is amplified and read at certain points.
- Sample type
- Block tumor tissue or blood
- Estimated result time
- Generally a few days to two weeks.
Limitations
- Only checks specific points, not the entire gene.
- Certain groups of mutations such as exon 20 insertions require other methods.
