NavDx is the first and only clinically validated circulating tumor-tissue–modified HPV (TTMV®) DNA blood test that aids in the detection of HPV-driven cancer. NavDx uses proprietary technology to quantify fragments of circulating TTMV HPV DNA, a unique HPV-driven cancer biomarker that cancer cells shed into the blood. This highly accurate blood test reliably uncovers the presence of HPV+ head and neck cancer across the care continuum.
