title: Uncertainty component evaluation in conventional microbiological qualitative measurements.
abstract: To couple method performance and QA in microbiological testing, uncertainty profiles have been developed according to relevant LODs and their confidence intervals. Percentage probability of failure is proposed to express this uncertainty. Analysis variance is divided into four categories: uncertainty originating from the sample, uncertainty originating from variations in procedure, uncertainty originating from the measurement system, and uncertainty originating in repeatabilitylreproducibility.
