Snippet: New York State influenza test data were compared with the recommended sample sizes for situational awareness as determined with Calculator A (Figure 2 ). To avoid bias, specimens should preferably be unscreened, or a random sampling. The Wadsworth Center Virology Laboratory receives specimens for influenza testing from many sources including some that are prescreened by IVADs or other methods.

Document: New York State influenza test data were compared with the recommended sample sizes for situational awareness as determined with Calculator A (Figure 2 ). To avoid bias, specimens should preferably be unscreened, or a random sampling. The Wadsworth Center Virology Laboratory receives specimens for influenza testing from many sources including some that are prescreened by IVADs or other methods. During most weeks of peak influenza activity, sample sizes needed to achieve ≥95% confidence levels for situational awareness were obtained only with a combination of randomly submitted Flu+ and MA-ILI specimens. During peak season, the recommended sample sizes were not achieved with only MA-ILI specimens, or outside of peak season with Wadsworth test data alone.
