Guardant360 Profiling System

**Semantic type:** Laboratory Procedure

**Definition:** A proprietary epigenomic and genomic profiling system for the identification of disease and treatment response biomarkers in cell-free circulating tumor DNA (ctDNA) found in liquid biopsy (blood) samples. This system uses next-generation digital sequencing technology to assist in the diagnosis of multiple solid tumor types, facilitate the selection of diagnosis-specific targeted therapeutics based on markers for treatment sensitivity or resistance and identification of new markers of disease progression, minimal residual disease and recurrence.
