Direct Detection
Although RESIST was initially developed for use on conventional overnight culture Coris BioConcept and many scientists recognise its potential for detecting and identifying carbapenemases without the need for overnight culture..
Below is a collection of references to work done exploring RESIST's potential.
Blood cultures - A positive blood culture can be treated with the standard protocol following lysis and concentration steps. Carbapenemase detection and identification is obtained within one hour of a blood culture flagging positive.
Rectal swabs - Following a period of enrichment in broth supplemented with a carbapenem sensitive and specific results are obtained. This has the potential to reduce carbapenemase screening to a matter of hours at a significantly lower cost than PCR options.
Development of validated protocols is underway

Abstract
Background:
Rapid and effective screening of carbapenemase-producing Enterobacteriaceae (CPE) appears essential for adequate patient management and rapid implementation of infection control measures. Most of these screening techniques require a minimum of 24 h of culture. Molecular assays are an exception since these can be achieved within 1 h, but are expensive and usually require specialized facilities and trained personnel. In this context, lateral immunochromatography performed directly from rectal swab samples could represent a cost-effective alternative with a reduced turnaround time.
Objectives: In this study, we assessed the performance of the OKN K-SeT test (Coris BioConcept, Gembloux, Belgium) for the rapid detection of OXA-48, KPC and NDM CPE directly from rectal swab samples.
Methods: A total of 149 residual rectal swabs, routinely screened for CPE through selective culture and confirmed by PCR, were tested with a defined protocol consisting of a 2.5 h incubation of the swab in an enrichment medium containing meropenem followed by OKN K-SeT testing after centrifugation.
Results:This method displayed an overall sensitivity of 96% and a specificity of 100% with a limit of detection ranging between 104 and 105 cfu/mL.
Conclusions: Whereas this assay appears highly specific, it displays a reduced sensitivity compared with the standard procedure encompassing a culture step. Nonetheless, this rapid method allows an accelerated identification of most CPE carriers at a lower cost and, accordingly, the implementation of early appropriate management procedures.

Abstract
We evaluated the performance of OXA-48 K-SeT assay for detecting OXA-370 directly from spiked rectal swabs and blood culture vials. The limit of detection of this test was 104UFC/mL for rectal swabs. Detection of the OXA-370-producing isolates was successfully achieved directly from positive blood culture vials independent of growing conditions.

Abstract
We evaluated the performances of the RESIST-4.O.K.N.V assay (Coris®) on 98 isolates to detect OXA-48-like, KPC-, NDM- and VIM-type carbapenemases directly on positive human blood cultures. OXA-48-like and KPC-type isolates were correctly detected but detection of NDM and VIM-type was weak and variable. We show that repeating the test on a 4-hour subculture improves the detection of NDM- and VIM-type to 100%.
