 Diagnostic sensitivity and specificity for nasal swab samples (n=133) tested by (a) “perfect match” M gene RRT PCR assay and (b) “H1‐118” RRT PCR assay.

n=133		VI or independent H1N1v identification		Total
		+	−
(a) *“Perfect match” M gene RRT PCR	+	28	5	33
	−	0	100	100
Total		28	105	133
(b) †“H1‐118” RRT PCR	+	28	1	29
	−	0	104	104
Total		28	105	133

Sensitivity for both assays: 28/28+0 = 100%

* Specificity: 100/5+100 = 95·2%

† Specificity: 104/1+104 = 99·1%
