How to use CM nasal swab
Nasopharyngeal swab sampling process
1. Please keep the subject’s head still and remove the secretions on the surface of the anterior nostril.
2. Use a swab or other tool to measure the distance from the nostril to the root of the ear and mark it with your fingers.
3. Insert the swab gently and slowly through the nasal cavity (if both nostrils need to be collected, another swab should be used).
4. Swab to the finger mark or stay for several seconds after encountering resistance to absorb secretions (generally stay for 15 ~ 30 seconds, and then rotate gently for 3 times).
5. Gently rotate and take out the swab and place it in the virus sampling tube (transport medium); Break the swab tail rod along the breaking point and place it completely in the tube. Tighten the pipe cover.
6. Note the information of the tested person and send it to the laboratory for inspection as soon as possible.
