The Carba NP test has multiple benefi ts. It is inexpensive,
rapid, reproducible, and highly sensitive and specifi c.
It eliminates the need for using other techniques to identify
carbapenemase producers that are time-consuming and less
sensitive or specifi c. Using this accurate test would improve
detection of patients infected or colonized with carbapenemase
producers. The test has been routinely implemented
in our microbiology department at Hôpital de Bicêtre and
is giving excellent results (data not shown). In addition, use
of the Carba NP test has greatly decreased the laboratory
technicians’ workload and simplifi ed the clinical management
of potential carbapenemase producers.
