Liquid Biopsy Analysis

Detect and monitor circulating biomarkers efficiently for clinical insights with liquid biopsy
Liquid biopsy is a minimally invasive method that reduces the need for tissue samples. Clinical applications of CTC and ctDNA testing in patients treated with immunotherapies have shown both predictive and prognostic value through the detection of genomic biomarkers as well as allowing for real-time monitoring of circulating tumor burden and the assessment of early on-therapy responses.
 
Precision specializes in developing approaches and technologies to maximize the biomarker information available from limited liquid biopsy samples.
