To access the Certificate of Analysis (COA), please use our COA Search.


  1. A special lysis reagent is added to the enrichment sample. Target pathogen DNA or RNA is released through the lysis step.
  2. The lysed sample is added to ANSR reagents. A special primer targets specific regions of the pathogen DNA and starts amplification of the DNA, creating millions of copies in minutes.
  3. The amplified segments of the pathogen DNA bind to special molecular beacons which then fluoresce and are detected by the ANSR reader.
  4. Results will be reported in 18 minutes for and displayed as positive, negative or invalid.
