Circulating Tumor DNA (ctDNA) Sequencing

A New Generation of Cancer Biomarkers – Circulating Tumor DNA (ctDNA) Detection and Monitoring

Circulating tumor DNA (ctDNA) are fragments of DNA from dying cancer cells found in the blood of cancer patients. At Ayass BioScience, we utilize a minimally invasive method (alternative to risky and invasive tumor biopsies) that requires only a few milliliters of plasma from patients to detect mutations in genes associated with cancer. ctDNA is detectable for most types of cancer and could be used as an effective screening method and as a way to monitor the response to therapeutic treatments for most patients.



Our ctDNA panel targets 28 genes commonly found mutated in solid tumor type cancers. This assay is performed using cell free DNA isolated from human plasma specimens. The test is intended to identify the presence of circulating tumor DNA and identify mutations in genes associated with cancer. The test can be used for the monitoring of cancer remission after treatment such as chemotherapy, radiation or surgery.
