HMM: Study finds widespread use of unregulated molecular urine tests in older adults. “Although urine culture is the traditional test for UTI, multiplex panels produce faster results, are more analytically sensitive, and can simultaneously detect multiple pathogens and some antibiotic-resistance genes. While the Food and Drug Administration has approved multiplex molecular syndromic panels for bloodstream, respiratory, and other types of infections, it has not approved any such test for UTI diagnosis. However, the panels exist as laboratory-developed tests, and they can be used in labs certified under the Clinical Laboratory Improvement Amendments of 1988.”
