LipoScience, Inc. is pioneering a new field of personalized diagnostics based on nuclear magnetic resonance (NMR) technology. The company's first proprietary diagnostic test, the NMR LipoProfile® test, measures the number of low-density lipoprotein particles (LDL-P) in a blood sample and provides physicians and their patients with actionable information to personalize management of risk for heart disease. To date, over 10 million NMR LipoProfile tests have been ordered. LipoScience's automated clinical analyzer, Vantera®, has been cleared by the U.S. Food and Drug Administration (FDA).
