New Performance and Clinical Outcome Data from Twelve Studies Using Nanosphere's Infectious Disease Tests to be Presented at ASM 2014

NORTHBROOK, Ill., May 16, 2014 (GLOBE NEWSWIRE) -- Nanosphere, Inc. (Nasdaq:NSPH), a company enhancing medicine through targeted molecular diagnostics, today announced that new performance and clinical outcome data for three Verigene® multiplex infectious disease tests will be presented at the 114th General Meeting of the American Society for Microbiology (asm2014), to be held in Boston, Massachusetts on May 17 – 20, 2014.

Among the 12 posters being presented, seven will highlight performance of the recently FDA-cleared Verigene Gram-Negative Blood Culture Test (BC-GN) and the importance of rapid detection of multidrug-resistant gram-negative bacteria. Four posters will highlight clinical outcomes data for the FDA-cleared Verigene Gram-Positive Blood Culture Test (BC-GP). The remaining poster will compare the performance of the FDA-cleared Verigene Respiratory Virus Plus (RV+) Test with two other commercially available assays for detection of influenza and respiratory syncytial virus (RSV).

The following posters will be presented at asm2014 during the following dates and times in Exhibit Hall B:

About the Verigene® System

The Verigene System uses Nanosphere's core proprietary gold nanoparticle chemistry to offer highly sensitive, highly specific molecular diagnostic results through low-cost multiplexing. The Verigene System rapidly and accurately detects infectious pathogens and drug resistance markers by targeting conserved genetic regions of a bacterium or virus. Currently, the multiplexed Verigene assays target infections of the blood, respiratory tract and gastrointestinal tract. The information gathered from Verigene test results enables clinicians to make informed patient treatment decisions more quickly, which may result in improved patient outcomes, reduced costs, optimized antibiotic therapy, and reduced spread of antibiotic resistance.

About Nanosphere, Inc.

Nanosphere is enhancing medicine through targeted molecular diagnostics that result in earlier disease detection, optimal patient treatment and improved healthcare economics. The Company's versatile technology platform, the Verigene® System, enables clinicians to rapidly detect the most complex, costly and deadly infectious diseases through a low cost and simple-to-use multiplexed diagnostic test. The combination of this innovative technology and Nanosphere's customer-driven solutions keeps commitment to the patient at the forefront of its business. Nanosphere is based in Northbrook, IL.
