Table 3 Summary results on positive proportions and virus titer present in the pooled-swab samples; unless stated otherwise, the results are for samples that are considered RT-PCR positive i.e., those with CT ≤ 35

From: Quantifying the effect of swab pool size on the detection of influenza A viruses in broiler chickens and its implications for surveillance

Subtype Pool size Number RT-PCR positive/Total (% a) Mean titer for PCR positive samples in EID50/ml Highest titer in EID50/ml Number FluDETECT positive (% b) Mean titer for FluDETECT positive in EID50/ml
