Swab manufacturers & suppliers
Nasopharyngeal swabs are suitable for collecting and transporting virus specimens such as covid-19, clinical influenza, avian influenza, hand, foot and mouth disease, and measles, as well as specimens of chlamydia and mycoplasma.
In order to respond to this round of the epidemic, stop the spread of the virus and reduce the risk of infection.
At present, we have successively carried out multiple rounds of swab testing for the new coronavirus.
Why are oropharyngeal swabs and nasopharyngeal swabs performed in covid swab testing?
covid flocked swab
Nasopharyngeal swab refers to the collection of secretions from the throat or nose of a patient with a specialized sterile flocked swab.
We generally use nasopharyngeal swabs to detect viral nucleic acids, viral antigens, and bacterial cultures.
The collection site of the oropharyngeal swab should be the pharynx and tonsils.
The basic steps of collecting the pharyngeal swab are to tilt the patient’s head back, open the mouth wide, and remove the secretions on the surface of the nasal cavity.
The sampler fixed the tongue with a tongue depressor and used polyester or calcium alginate test paper to cross the base of the tongue.
Wiped the posterior pharyngeal wall and the lateral wall of the tonsillar recess 3-to 5 times to collect mucosal cells.
Remove the swab gently, avoiding contact with the tongue, uvula, oral mucosa, and saliva, and insert the swab back into the sampling device or a suitable transport device.
Nasopharynx swab vs oropharyngeal swab
The main difference between the two lies in the sampling method and sampling location.
The detection rate and accuracy of nasopharyngeal swabs are higher than those of oropharyngeal swabs.
Still, nasopharyngeal swabs are more complicated and difficult to operate, and people with nasal diseases。
Such as rhinitis and nasal polyps will not easily adapt, Bleeding may occur during the collection process, so the collection speed is slow.
Compared with nasopharyngeal swabs, oropharyngeal swabs are fast, simple and easy to collect.
And the detection rate can meet the requirements.
Therefore, oropharyngeal swabs are often used in large-scale screening.
For key groups or middle- and high-risk groups.
Required to collect nasopharyngeal swabs, or even stool and blood samples.
In addition to nasopharyngeal swabs and oropharyngeal swabs.
There are also detection methods such as serum, anal swabs, deep cough sputum, nasopharyngeal or respiratory tract extracts, and bronchial lavage fluid.
In general, the method of sample collection will be determined according to different populations and different needs.
