① Ask the patient to sit down, tilt his head back, grow his mouth and make an "ah~~" sound

 

②The sampler uses a disposable sampling swab (preferably a flocked swab) and crosses the tongue root to the posterior pharyngeal wall and tonsillar crypt, lateral wall, etc.

 

③ repeatedly wipe the posterior pharyngeal wall with the swab 3-5 times to collect mucosal cells (sputum specimens absorbed by the swab)

 

 

 

④Gently take the swab out of the patient's mouth without touching the tongue, pendulous body, oral mucosa and saliva to avoid contamination

 

⑤ Gently place the swab vertically into the virus sampling tube, forbidding touching the wall of the tube to avoid contamination

 

⑥Gently break the swab at the fracture point at the mouth of the tube wall, and discard the broken end of the swab

 

(7) Close the cap of the virus sampling tube and check the patient's information to avoid mixing

 

⑧Put the collected virus sampling tube vertically into the delivery box to prevent leakage

 

⑨ Send it to the laboratory for testing in time or as soon as possible.
