  • a The percentage of laboratory-specific OIs within 2- and 3-fold of the overall consensus value is shown. The fold range from the overall consensus needed to include 90% of the values [identified as Fold (90%)] is also shown. Outlier results are included in this analysis. Pn, pneumococcal serotype.
