Detection of carbapenemase activity in Enterobacteriaceae using LC-MS/MS in comparison with the neo-rapid CARB kit using direct visual assessment and colorimetry
The Neo-Rapid Carb test may accurately detect OXA-48-like carbapenemases. Lysis may be essential for the detection of weaker carbapenemases such as OXA-48. Colorimetry may be used to help interpret Neo-Rapid Carb test results.
