Liquid Biopsy & Circulating Tumor DNA (ctDNA) Testing
Minimally invasive blood test detecting cell-free circulating tumor DNA fragments to identify resistance mutations and minimal residual disease (MRD).
Clinical Overview & Diagnostic Rationale
Liquid biopsy isolates fragments of tumor DNA shed into peripheral bloodstream. It offers a non-invasive tool to monitor tumor genetic evolution, detect emergent drug resistance mutations (e.g. EGFR T790M/C797S), and measure minimal residual disease.
Primary Indications & Clinical Scenarios
Blood sample collected into specialized Streck ctDNA preservative blood collection tubes.
