Why Genetic Testing?

Family History Doesn’t Reveal the Full Story

Genetic testing is important even for those with no family history of disease.

Historically, genetic tests to screen for disease have been limited to high-risk populations – individuals who are symptomatic or affected with a particular condition. By making access to holistic screening easier, Phosphorus is providing the opportunity to maximize disease prevention and early detection for those at risk, as well as anyone wanting to seek more definitive information about their health.”

Malgorzata Jaremko, SVP of Clinical Diagnostics & Research, CLIA Laboratory Director

43% of people tested for variants associated with cancer risk had no corresponding family or personal health history.
