[Storage Conditions and Shelf Life] The sampling tube should be stored at 4–25°C; the shelf life is 12 months.

[Sample Requirements]

Collected samples shall be transported at 2–8°C and submitted for testing immediately; the total transport and storage time shall not exceed 48 hours.

【Instructions for Use】

1. Before sampling, label the sampling tube with the relevant sample information.

2. Depending on the specific sampling requirements, collect a sample from the nasopharyngeal region using a sampling swab;

3. The specific sampling method is as follows:

a) Nasal swab: Gently insert the swab tip into the nasal cavity up to the nasopharyngeal area, hold it in place for a few seconds, then slowly rotate and withdraw. Use a second swab to sample the other nostril, immerse the swab tip in the collection solution, and discard the tail end.

b) Pharyngeal swab: Use the swab to gently wipe both palatine tonsils and the posterior pharyngeal wall, then immerse the swab tip in the collection solution, discarding the handle.

4. Quickly place the swab into the sampling tube;

5. Break off the portion of the sampling swab that extends above the sampling tube, then tightly screw on the tube cap.

6. Newly collected clinical samples shall be transported to the laboratory within 48 hours at 2–8°C.

【Limitations of the Testing Method】

1. Contamination of samples after collection can affect the final test results;

2. Failure to store samples at the prescribed temperature will affect the final test results;

【Product Performance Specifications】

1. Appearance: The sampling tube shall be clean, free of impurities and any visible defects; the sampling solution shall be a clear red liquid or a colorless, transparent liquid. The label shall be intact, neatly and securely affixed, with clear and accurate text and symbols.

2. pH: At 20–25°C, the pH of the sampling solution should be 7.0–8.2.

3. Fill Volume: The fill volume of the sampling solution shall be no less than ±10% of the labeled volume.

4. Stability: The product shall maintain stable physical and chemical properties for at least one month beyond its expiration date.
