Nanosphere’s motto is “advancing diagnostics through the power of nanotechnology.” While I’ve read enough science fiction to quibble with the “nanotechnology” designation, Nanosphere does seem to have a handle on rapid molecular testing. The Verigene System can analyze samples for respiratory viruses (Influenza A, Influenza B, RSV, and 2009 H1N1, to name a few), C. difficle, and gram-negative or gram-positive organisms in positive blood culture bottles.
While other rapid molecular analyzers exist for C. difficle and respiratory viruses, I’m intrigued by the blood culture analysis. Literature from the company claims that analyzing one sample using one cartridge can give you identification and resistance information for organisms commonly implicated in septicemia. With the rising prevalence of multidrug resistant bacteria such as MRSA, CRE, and Acinetobacter baumanii, getting these results almost two days faster than current methodologies would have a positive impact on patient care.
A recent study suggests that this system does what it claims to do–rapidly identify organisms and resistance patterns in positive blood cultures.
Have any of you tried this system? If so, what are your thoughts?
