Filled APS containers should be agitated, swirled, or inverted before incubation to ensure contact with the media with all interior surfaces in the container. The number of reject containers during the APS batch should not be more than the number of rejects during routine production batches including, for example, those containers that are rejected during the start-up of filling. All integral containers should be incubated, including those with cosmetic defects and those that have undergone non-destructive in-process control checks.
