Nanogen has developed a strong product and proprietary technology base in advanced diagnostic solutions for two of the fastest growing in vitro diagnostic (IVD) markets – molecular diagnostics and rapid point-of-care testing. The role of diagnostics in healthcare is evolving rapidly buoyed by new and improved technologies that allow the advancement and decentralization of diagnostic applications. Products like those from Nanogen are quickening the pace toward personalized medicine. Both clinical laboratories and point-of-care providers are seeing strong validation of the contribution advanced diagnostic tests can have for the delivery of better, more personalized patient care. With its growing diagnostics product offering, Nanogen is poised to become a key player in this arena.
Nanogen’s products are used in multiple segments of the global IVD market - including applications in which testing is used as a prognostic indicator of disease and for ongoing monitoring of disease. Products include a broad menu of real-time PCR reagents and kits for DNA and RNA infectious disease targets as well as genotyping assays for key biomarkers in onco-hematology. The Company’s rapid tests for acute cardiac conditions and drugs of abuse are sold to customers requiring rapid results at or near the point of treatment such as emergency rooms.
All of Nanogen’s products are designed to improve the role diagnostics plays in improving individual patient care by providing more specific DNA-based results or by moving the diagnostic capability and decision closer to the patient. The strong intellectual property portfolio of advanced diagnostic technologies allows the company to bring unique solutions to the market. The IP portfolio includes: the MGB Eclipse® probes technology which is widely licensed and has proven to be a mainstay in helping to make real-time PCR a gold standard method in molecular biology research and diagnostic testing; and key patents for the reporting of multiple biomarkers in a rapid test format.
