AST Workflows

Antimicrobial Susceptibility Testing (AST) is optional. Your lab will only see these workflows if the AST add-on and supporting setup data are enabled.

Setup Concepts

ConceptMeaning
AST PanelA predefined organism/antibiotic matrix
Breakpoints TableRules used to infer Susceptible, Intermediate, or Resistant categories
Microorganism IdentificationAnalysis used to select organisms found in the sample
Selective ReportingControls which organism/antibiotic results appear on the final report

Basic AST Flow

  1. Assign Microorganism identification to the sample.
  2. Select identified microorganisms.
  3. Add an AST panel to the sample.
  4. Enter zone diameter or MIC values.
  5. Review calculated S/I/R categories.
  6. Use selective reporting if only some results should publish.
  7. Submit, verify, and publish through the normal workflow.

Supported Result Formats

AST result entry supports plain numbers, comparison operators such as <, >, <=, >=, and MIC fractions such as 1/2 or 1/4 where configured. Exact numeric and fraction values can be used for breakpoint calculation; operator values may require manual category selection.

Not Tested Antibiotics

If an antibiotic remains in a panel but was not tested, use the configured reject/not-tested workflow. The result should display as not tested instead of implying a missing value.

Caveat

Do not document AST as available to a customer unless their Clearline tenant has the AST add-on, microorganism setup, antibiotic setup, panels, and report template behavior configured.
