01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Diagnosis of non-small cell lung cancer (NSCLC)
  • ✓Guiding treatment decisions for EGFR-mutated cancers
  • ✓Identifying patients eligible for specific targeted therapies
  • ✓Monitoring treatment response in some cases
  • ✓Assessing prognosis in certain cancer types

In plain language

What this test helps you understand

Identifies specific mutations in the EGFR gene (exons 18-21) that can predict response to targeted cancer therapies, aiding in personalized treatment planning.
The EGFR Gene Selective Sequencing of Exons 18-21 NGS Genetic DNA Test is a diagnostic tool used in oncology. It uses Next Generation Sequencing (NGS) technology to detect mutations in the Epidermal Growth Factor Receptor (EGFR) gene. This gene is important in the development and progression of certain cancers, especially non-small cell lung cancer (NSCLC).

This test specifically looks for mutations in exons 18 to 21 of the EGFR gene. Identifying these mutations can help determine how effective certain targeted therapies might be, allowing for more personalized cancer treatment plans.

Patients diagnosed with cancer, particularly non-small cell lung cancer, may benefit from this test. Discuss with your doctor if this test is appropriate for you.

Understanding the results requires interpretation by a healthcare professional. A genetic counseling session may be recommended to discuss the findings and potential implications for treatment.

SampleBlood sample (EDTA tube) or tumour tissue sample. Confirm specific requirements with the laboratory before booking.
MethodologyNext Generation Sequencing (NGS) of the specified EGFR gene exons.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test only analyzes exons 18-21 of the EGFR gene. It may not detect mutations in other parts of the gene or other genes involved in cancer. Results should be interpreted in the context of the patient's overall clinical picture.

Questions people ask

Frequently asked questions

The EGFR gene provides instructions for making a protein involved in cell growth and division. Mutations in this gene can contribute to cancer development.
Mutations in these specific exons of the EGFR gene are commonly associated with sensitivity to certain targeted cancer therapies.
This test is typically recommended for patients diagnosed with certain types of cancer, especially non-small cell lung cancer, to guide treatment decisions.
Results help doctors determine if a patient might benefit from specific targeted therapies that block the action of the mutated EGFR protein.
Genetic counseling is recommended to help understand the results and their implications, but it may be arranged separately. Please inquire with the laboratory.
