In laboratory testing there are potential "uncertainties" that may affect test results (for example, specimen not collected correctly, presence of antimicrobials, biological variation)
Additionally factors within the laboratory may lead to variation (for example, incubation times, time to processing)
The Microbiology laboratory has measures in place to minimise the level of uncertainty in any test result and participates in Quality Assurance schemes. There is an on-going programme to calculate uncertainty of measurement for quantitative tests and this information will be available to view on the Tests and Tubes website as it proceeds
All results provided by the Microbiology Laboratory are representative of the sample tested and results must always be considered against clinical presentation.
