How do you establish cut-offs?

Cutoffs Tab

  • By default, the QuickScan software will display and record “Accept” on the Results screen. The Cutoff feature allows the user to select an Action other than “Accept” as the default when test results are equal to or greater than a user-defined cutoff level. When the Cutoff feature is used, the program allows the user to select Accept, Pending, or Redirect as a default Action in the Results screen.
  • Cutoffs can be defined for each of the Mycotoxin test kits. The cutoff will be applied to each individual result within the results screen, even if multiple strips of the same test are scanned at one time. Thus, strips from multiple samples can be scanned at one time, and each one will be compared individually to its respective cutoff. Likewise, multiple Mycotoxin test kits run and scanned from the same sample will be evaluated independently using the cutoffs for each mycotoxin.
  • For GMOs, the defined cutoff will be applied to the Summed GMO result within the scan, either for corn or for soy. Thus, when using the cutoff feature, strips from only one sample should be scanned at a time.
  • If multiple GMO test kits from the same sample are scanned at one time (for example, a comb and a single strip), the program will sum the results and display the same Action for each.  Please note, to view the calculated GMO Sum, this option must be enabled in the Selections tab.
  • Cutoff levels that are met or exceeded will be flagged on the Results screen in the Error column. A user-defined message (such as the default “Exceeds Cutoff”) will appear shaded in red. Users can change the default error message in the Cutoffs tab. The Action column will display the default action selected by the user in the Cutoffs tab. Please note, the user can override the default Action in the Results screen by using the toggle.
