Nasopharyngeal swab

Nasopharyngeal swab

What is a nasopharyngeal swab?

Nasopharyngeal swabs are actually relatively long sampling swabs.

Not only are relatively long disinfection sampling swabs, but their main function is to use nasopharyngeal secretions for bacterial culture and drug sensitivity testing.. Through bacterial culture and drug sensitivity test, the source of infection in the nasopharynx and the microbes in the nasopharynx can be selected,

and then a drug sensitivity test can be done to determine which drugs are sensitive,

so that sensitive drugs can be selected for treatment, so as to achieve better results Effectiveness,

so the nasopharyngeal swab is actually a sampling swab for taking tissue samples.

Nasopharyngeal swab specimen collection

Nasal swab collection method

purpose

Normal people’s pharyngeal isthmus culture should have normal oral flora without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and do not cause disease under normal circumstances, but infections can occur under the body’s systemic or local resistance and other external factors to cause diseases. Therefore, pharyngeal swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, and acute pharyngitis.

Nasal swab collection method

①. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nasal cavity. The collector can stand on the side of the collector, reducing occupational exposure caused by coughing and sneezing, and alleviating the pressure on the collector.

②. Measure the distance from the nostril to the root of the ear with a swab and mark with your hand.

③. Gently insert the swab into the nostril in the direction perpendicular to the nose (face) through the nasal cavity, with a feeling of touching the wall until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then gently rotate it 3 times.

④. Put the swab into the virus transport medium, not only to break the swab stick, but also to put it completely into the test tube.

⑤. Tighten the cap of the tube, mark it, put it in a plastic bag and seal it.

⑥. Submit the specimens for inspection in time
