Northstar Response®
Therapy Response Monitoring
Northstar Response® is a tissue-free, NGS-based test that evaluates >500 genomic loci uniquely methylated in cancer cells. The test precisely measures the number of methylated, circulating tumor DNA (ctDNA) molecules in each blood sample, reflecting the patient’s tumor burden. Charting the patient’s methylated ctDNA values over time is indicative of response, progression or stable disease.
