Lab-on-a-Disc Device Detects Urinary Tract Infections in About an Hour
http://www.medgadget.com/wp-content/uploads/2015/08/UTI-detector.pngUTIs are a common occurrence in hospitalized patients with catheters, but they’re typically detected too late and can lead to sepsis. Currently, a diag**stic test can take hours to provide results. Researchers from Ireland and Germany have **w created a “Lab-on-a-Disc” device that can separate and detect bacteria in tiny samples of urine. The device is a centrifuge that spins a few microliters of a urine sample. On the periphery of the spinning disk are microchannels leading to tiny vessels called “V-cup capture units” that collect individual bacteria. A Raman spectroscopy probe then uses light to analyze the bacteria.
In their studies, the team was able to spot E. coli and*Enterococcus faecalis*bacteria that are often associated with UTIs in just over an hour using small*patient samples. This may allow clinicians to quickly screen patients for sepsis and begin antibiotic treatment a full day earlier than is **w typically possible.
