Sterile Sample Sampling Swab Notes

Considerations for sterile specimen collection swabs include:

1. Low temperature storage: Sterile swabs should be stored at a temperature of 2-8°C for no more than three months to ensure their effectiveness and stability.

2. Avoid repeated freezing and thawing: Repeated freezing and thawing of sterile swabs will destroy the nucleic acid in them and affect the test results, so try to avoid repeated freezing and thawing.

3. Pay attention to the expiration date: The sterile swab is valid for 7 days after opening. Be careful not to exceed the expiration date.

4. Avoid contamination: Before using a sterile swab, you should ensure that it is not contaminated, so it needs to be strictly disinfected.

5. Dry storage of swabs: Sterile swabs should be stored in a dry environment, avoiding moisture and high temperature to extend their shelf life.

6. Note: Avoid using after freeze-thaw cycles, as this will destroy the nucleic acid in the swab and affect the test results. If the swab has become damp, it should be discarded.

In short, sterile sample collection swabs should be stored and used in a low-temperature, dry, and contamination-free environment to maintain their effectiveness and stability.
