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.
