SAN JOSE, Calif.--(BUSINESS WIRE)--Chronix Biomedical - developing and applying proprietary techniques to detect and analyze circulating nucleic acid sequences for the diagnosis and management of disease - today reported that three recent studies published in peer-reviewed journals have further confirmed the potential diagnostic and prognostic utility of fragments of DNA and RNA that circulate in the blood, known as circulating nucleic acids (CNAs). Data from these studies confirm previous findings showing that CNAs can identify the presence of certain diseases in blood samples months to years before clinical symptoms appear.
