[Sample requirements]
The collected nasopharyngeal Swab samples should be transported at 2°C to 8°C and sent for inspection immediately, and the sample delivery and storage time should not exceed 48 hours.
[Testing method]
1. Before sampling, mark the relevant sample information on the label of the sampling tube.
2. According to different sampling requirements, use a sampling swab to sample in the nasopharynx.

2. If the sample is not stored at the specified temperature, the final test result will be affected.
