The Particulars: Timely detection of carbapenemase-producing, carbapenem-resistant enterobacteriaceae is critical to patient care and infection control. Few studies have assessed tests for detecting these organisms accurately and quickly.

Data Breakdown: Swiss investigators developed and studied a new diagnostic, the Carba Np test, in detecting carbapenem-resistant organisms. The test achieved a sensitivity of 92% and a specificity of 100% in identifying known carbapenemase producers. Positive test results were determinable in as few as 10 minutes or up to 2 hours. Negative test results took up to 2 hours.

Take Home Pearl: The novel Carba Np test appears to quickly and accurately identify carbapenem-resistant organisms.
