Tips for using oropharyngeal swabs

The oropharyngeal swab is a sampling tool used to extract mucosal cells and secretions from the oropharynx.

The sampling method requires the use of sterile throat swabs and other items to penetrate deep into the pharynx,

Not only go through the base of the tongue to reach the posterior pharyngeal wall, tonsil recesses, side walls, etc.,

but also wipe left and right 3 to 5 times, and then gently remove the cotton swab.

Then put the swab stained with mucosal cells and secretions into the virus sampling tube and send it for inspection in time.


1.Ask the patient to sit down, not only let the patient tilt their head back and open their mouth, but also let the patient make an “Ah~” sound.

2.The sampler can fix the tongue with a tongue depressor, and use an oropharyngeal swab

to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, side wall, etc.

3.Wipe 3 to 5 times repeatedly to collect mucosal cells.

4.Not only must gently remove the cotton swab, but also avoid contact with the tongue, pituitary gland, oral mucosa and saliva.

5.Put the sampling swab and the sample vertically into the virus sampling tube,

Not only do you have to break the swab where it breaks, but also discard the end of the swab.

6.Tighten the cap of the tube,

put it in a biosafety bag, and send it for inspection in time.


1.For purulent pharyngitis, the bacterial culture of oropharyngeal swabs is mainly

used for screening group A β-hemolytic streptococcus and hemolytic cryptobacteria.

2.When testing Neisseria gonorrhoeae in oropharyngeal swabs, the clinic needs to inform the laboratory in advance.

3.For pediatric patients, Haemophilus influenzae should  reported routinely.

4.Under normal circumstances, not only cannot the throat swab sample be used alone to diagnose upper respiratory tract infections, but it must also be used in combination with a nasopharyngeal swab

Suction to increase the detection rate of pathogens of respiratory tract infections.
