Carba NP vs Rapid CARB Screen Kit in detecting carbapenemase producing Enterobacteriaceae and Pseudomonas

- Resistance against carbapenems is increasing among Enterobacteriaceae and Pseudomonas.
- Fast detection is needed to implement infection control measures.
- Carba NP test is a biochemical test that can detect the organisms harboring carbapenemase producing genes. Rapid CARB Screen Kit uses this principe too.
- We compared these two tests.
- We found Carba NP test sensitivities of 91.1 % and 100 % for Enterobacteriaceae and P. aeruginosa, respectively. 
- The Rapid CARB Screen Kit had sensitivities of 73.3 % and 66.7 % for Enterobacteriaceae and P. aeruginosa, respectively.
- The specificity of both tests was 100 %. 
- The approximated price for performing one Carba NP test was 0.31 Euros and for CARB Screen Kit, it was 1.25 Euros. 
- The paper is published in EJCMID and can be found here.
