The IvyGene test is a blood test that uses advanced DNA sequencing methods to detect the DNA methylation pattern of circulating tumor DNA (CTDNA) in blood samples in order to both confirm the presence of cancer and quantify cancer presence. Unlike many genetic tests that investigate DNA mutations to determine the propensity or possibility of developing cancer over time, the IvyGene test identifies DNA methylation patterns consistent with disease presence and gives quantifiable data about cancer presence at the time of testing.
