MC6163
MKTT/RV + XLD + BGA 37

A typical performance report from PORTAL, round MC 305. Results are colour-coded: green indicates satisfactory performance and red indicates unsatisfactory. This sample contained Salmonella Livingstone at 8 CFU/g, with 99.7% of participants reporting a correct result – which is a little higher than the expected performance for this matrix and level. The summary graph (below) shows performance scores across Salmonella PT rounds over a five-year period. On average, around 96% of results are satisfactory. This rate is unchanged for negative samples: even when no Salmonella is present, approximately 4% of participants still report a false positive.
