Check-MDR CT102

Your tool for characterizing carbapenem-resistant Enterobacteriaceae (CRE)

Find out which carbapenemase and/or ESBL types are present. Clear answers are delivered within a few hours.

  • Detect the clinically most prevalent carbapenemases and ESBLs in Enterobacteriaceae
  • Discriminate directly between ESBL and non-ESBL variants of TEM and SHV
  • Obtain objective results and improve traceability with the E-Ads software


Its use in clinical practice may contribute to better knowledge of local epidemiology of β-lactam resistance genes and to more appropriate use of antimicrobial agents, reduction of costs, and improved patient outcome.

  Time per step  Hands-on time per step 
1. Culture    

2. DNA extraction
of total nucleic acid using automated, magnetic bead or column-based methods (not supplied)


3. Identification
by multiplex ligation

3 h 15 min

4. Amplification
of ligated probes by PCR

1.5 h

15 min

5. Detection
through hybridization of amplified probes to specific locations on the microarray, contained in a Check-Points Array Tube
2 h 30 min
 6. Results
are generated using the Check-Points Tube Reader to produce an image of the microarray and the E-Ads software to automatically translate this image into the presence or absence of specific beta-lactamase genes

Carbapenemases and ESBLs

Detect the clinically most prevalent carbapenemases and ESBLs in Enterobacteriaceae. The microarray platform allows a broad range of relevant targets to be analyzed simultaneously and is also well-suited to detect co-resistance.

TEM and SHV ESBL vs. non-ESBL

Discriminate directly between ESBL and non-ESBL variants of TEM and SHV, eliminating the need for additional confirmatory sequencing. By employing a highly specific ligation reaction, wild type TEM and SHV and the exact point mutations that result in an ESBL phenotype can be accurately detected and differentiated.

Objective results

Obtain objective results and improve traceability with the E-Ads software. Data is displayed immediately onscreen, summarized in a convenient format after each run and may be accessed anytime via the E-Ads software database.
