Table 2 PCR/Electron spray ionization-time-of-flight-mass spectrometry (PCR/ESI-TOF-MS) versus traditional clinical microbiology (TCM) for detection of pathogens of potential clinical relevance on healthcare worker hands/personal protective equipment and high-use surfaces (n = 158)

From: Comparison of PCR/Electron spray Ionization-Time-of-Flight-Mass Spectrometry versus Traditional Clinical Microbiology for active surveillance of organisms contaminating high-use surfaces in a burn intensive care unit, an orthopedic ward and healthcare workers
