Abstract: Workflows for testing in automated laboratory environment are managed and controlled to permit prioritization and dependencies to be implemented for individual tests. Test groups can be specified to include analytical and non-analytical test requests. Instrument test status and/or sample location is used to determine whether workflow criteria is met. Each test can be assigned a completion criteria, which can foe used to retake other tests or operations contingent on the outcome of another test. Automation of the laboratory is enhanced with greater flexibility in controlling testing.
