NORTHBROOK, Ill., Oct. 22, 2012 (GLOBE NEWSWIRE) -- Nanosphere’s (Nasdaq:NSPH) Verigene Gram-Positive Blood Culture Nucleic Acid Test (BC-GP) (IUO), based on the company’s proprietary array-based nanoparticle technology, demonstrated overall sensitivity and specificity of 99%, respectively, for the detection of a broad panel of gram-positive bacteria from positive blood cultures, according to a recent study. The BC-GP Test also correctly detected the presence or absence of genes encoding vancomycin resistance in Enterococcus spp. and methicillin resistance in Staphylococcus aureus or S. epidermidis. Researchers concluded that the test, which required less than 5 minutes of user hands-on time, provided accurate organism identification and detection of resistance genes compared to routine laboratory methods.
