Liquid Biopsy Cell Free EGFR T790M L858R Exon 19 Deletion Test
Revolutionary Non-Invasive Genetic Testing for Lung Cancer
The Liquid Biopsy Cell Free EGFR T790M L858R Exon 19 Deletion test represents a groundbreaking advancement in precision oncology. This innovative diagnostic approach utilizes circulating tumor DNA (ctDNA) from peripheral blood samples to detect specific EGFR mutations that are crucial for targeted cancer therapy selection. Unlike traditional tissue biopsies that require invasive procedures, this liquid biopsy method offers a safe, convenient, and highly accurate alternative for monitoring treatment response and detecting resistance mutations.
What This Advanced Test Detects
Our sophisticated liquid biopsy screening identifies three critical EGFR mutations that significantly impact lung cancer treatment decisions:
- T790M Resistance Mutation: Detects acquired resistance to first-generation EGFR tyrosine kinase inhibitors
- L858R Activating Mutation: Identifies the most common EGFR sensitizing mutation in non-small cell lung cancer
- Exon 19 Deletion: Screens for the second most frequent EGFR mutation that responds well to targeted therapies
Who Should Consider This Genetic Screening?
This comprehensive EGFR mutation test is particularly valuable for:
- Patients diagnosed with non-small cell lung cancer (NSCLC)
- Individuals experiencing progression on first-line EGFR inhibitor therapy
- Patients considering EGFR-targeted treatment options
- Those who cannot undergo traditional tissue biopsy procedures
- Individuals requiring ongoing monitoring of treatment response
- Patients with suspected acquired resistance to current therapies
Clinical Indications and Symptoms
Consider this test if you’re experiencing persistent respiratory symptoms, have a lung cancer diagnosis, or are undergoing treatment with EGFR inhibitors. The test is especially relevant when traditional tissue sampling is challenging or when monitoring treatment efficacy over time.
Significant Benefits of Liquid Biopsy Testing
- Non-Invasive Procedure: Simple blood draw eliminates the need for surgical biopsies
- Comprehensive Mutation Detection: Simultaneously screens for multiple critical EGFR alterations
- Rapid Turnaround: Results available within 5-7 business days
- High Sensitivity: Advanced Droplet Digital PCR technology ensures accurate detection
- Treatment Guidance: Results directly inform targeted therapy selection
- Convenient Monitoring: Enables regular assessment of treatment response
Understanding Your Test Results
Your results will provide clear information about the presence or absence of specific EGFR mutations:
- Positive for T790M: Indicates acquired resistance to first-generation EGFR inhibitors, suggesting potential benefit from third-generation TKIs
- Positive for L858R or Exon 19 Deletion: Confirms eligibility for EGFR-targeted therapy with improved treatment outcomes
- Negative Results: May indicate absence of tested mutations or levels below detection threshold
All results should be discussed with your oncologist to determine the most appropriate treatment strategy based on your specific genetic profile and clinical situation.
