** Method does not detect organism but did not indicate subsequent procedure despite having received warning in previous survey: “In the future, please indicate whether a sample would be referred to another laboratory or if an alternate procedure would be used to identify the pathogen. CMPT now considers reporting the limitations of a method without indication of next steps as Unacceptable”.
