The importance of assay performance in aquatic disease diagnosis

4 The importance of assay performance in aquatic disease diagnosis 

Whether the laboratory uses their own in-house protocols or performs their diagnostic assays as described in OIE or accredited schemes, there are key considerations. The main factors to consider within assay development for any disease diagnostic laboratory are provided in Table 6.1 and were developed using the OIE principles and validation methods as a guide. All of these will already have been covered if they are part of an internationally recognised accreditation system and checks will be provided through the 

Correctness The correlation between the mean from a set of tests and the individual data. 

Repeatability Measure of variance between results from testing identical samples with the same methods. 

Reproducibihty Comparing test results between different laboratories using the same sample and materials.
