| previous result | MT-PCR resulta | ||
|---|---|---|---|
| IF (total) | 32 | ||
| INF-A (unspecified) | 6 | 6 | (H3 n = 4; H1 n = 1)b |
| RSV | 8 | 8 | |
| total INF-A/RSV | 14 | 22 | (14 + INF-A n = 8)c |
| total negative | 18 | 10 | |
| PCR (total) | 37 | ||
| INF-A (unspecified) | 17 | 17 | (H3 n = 5; H1 n = 1) |
| INF-B | 3 | 3 | |
| RSV | 2 | 2 | |
| total INF-A/-B/RSV | 23 | 28 | (+ INF-A n = 5) |
| total negative | 14 | 9 | |
| IF or PCR (total) | 45 | ||
| all INF-A | 18 | 24 | |
| all INF-B | 3 | 3 | |

| all positive results | 29 | 35 | |
| all negative results | 16 | 10 | |
aprofile 1 includes assays for INF-A, INF-B, H1, H3, H5, RSV and RV but not hPIV3; ball 6 were also PCR positive; cnot including INF-B (n = 3) detected by MT-PCR in samples which had not been tested for these pathogens
