Performance Evaluation of MALDI-TOF MS MBT STAR-BL Versus In-House Carba NP Testing for the Rapid Detection of Carbapenemase Activity in and Strains.

There is an urgent need to be able to identify carbapenemase-producing Enterobacterales. In this study we aimed to compare the performance of the MALDI Biotyper Selective Testing of Antibiotic Resistance-βLactamase (MBT STAR-BL) test with the in-house Carba NP test in their ability to rapidly detect carbapenemase production in and strains. MBT STAR-BL and Carba NP testing were performed in parallel.
