Pharyngeal swab collection.

Pharyngeal swab: Swab both sides of the pharyngeal tonsils and the posterior pharyngeal wall with a swab with a fiber head, again dipping the swab head in the sampling solution and discarding the tail.

The main function of the pharyngeal swab is to remove secretions from the pharynx and tonsils for bacterial culture and drug sensitivity testing. Usually, because of the presence of many flora in the pharynx, it is mainly necessary to breathe and pass food through the oral cavity, where some bacteria are present internally. When an infectious disease occurs, it is best to perform a bacterial culture and drug sensitivity test with a swab of the pharynx. The type of pathogenic bacteria is detected and the most sensitive drug is selected according to the test results, while it is possible to distinguish whether the infection is bacterial or anaerobic or fungal.

Nasal swab collection.

1 . Please keep the patient's head still and remove the secretions from the surface of the middle of the nasal tip hole.

2 . Gently go through the nasal cavity to the nasopharynx and slowly insert the wiper.

3 . After meeting resistance, reach the posterior nasopharynx and stay for a few seconds to aspirate the secretion.

4 . Gently rotate the wiper to remove it and place it into the transport medium.

5 . Wipers used for virological examination are immersed with the wiping head in the viral transport solution, throw away the tail and tighten the cap of the tube.

6 . Swabbers used for bacteriological examination are inserted into the sampling device or appropriate transporters.

Precautions for nasopharyngeal swab collection.

Must be collected prior to antibiotic medication.

Specimens should not be rinsed with antiseptic or applied locally to the lesion several hours prior to collection.

When collecting specimens with cotton wipes, be careful not to touch the tongue, oral mucosa, saliva, and to collect carefully and correctly at the collection site to prevent contamination.

When diphtheria bacillus infection is suspected, specimens should be collected in deep pharyngeal tissues to avoid contamination of the normal flora on the pharyngeal surface.

When collecting tonsillar specimens, the tonsillar fossa is better.

When collecting specimens, a mask and gloves must be worn to prevent infection.

The pharynx is the passage for breathing and food, and it is better to start collection in the morning.

Collect 2 tubes of wipers to facilitate direct smear stain microscopy and inoculation for culture.
