aFor H. influenzae serotype, the previous results are SAST: BMGAP serotype predictions are reported as Pos in the table if the isolate was serotypeable and the predicted serotype matched the SAST results. BMGAP serotype predictions are reported as Neg if they are non-typable or do not match SAST results. No discrepancies were observed between BMGAP and SAST. bFor N. meningitidis serogroup, the previous results are SASG: BMGAP serogroup predictions are reported as Pos in the table if the isolate was serogroupable and the prediction matched the SASG results. BMGAP serogroup predictions are reported as Neg if they are non-groupable or do not match SASG results. Discrepancies are described in Table 3.
