The results of novel coronavirus nucleic acid detection are an important reference for diagnosis and curative effect evaluation of new coronavirus pneumonia. Nucleic acid screening samples are mostly from deep cough sputum or throat swabs, and throat swabs are divided into nasopharyngeal swabs and oropharyngeal swabs.

The operator often needs to face the patient’s mouth. During the collection process, the patient is prone to irritating dry cough, vomiting, and other symptoms, so that the collector is exposed to the aerosol with a virus. Huachenyang manufacturer diagnostic & Specimen Collection Swabs

There are several advantages to a nasopharynx swab. In order to obtain more samples, it is also the reason why the positive rate of throat swab is higher than that of the oropharyngeal swab.

In addition, patients with good tolerance, usually can first nasal mucosa surface anesthesia and contraction, skilled samplers can sample patients without anesthesia.

Because the operator can stand behind the side of the patient when sampling the nasopharynx, the patient can pull down the mask only to expose the nostril, cover the mouth, do not need to look directly at the patient’s mouth, and there is basically no pharyngeal reflex, so the exposure risk is quite low. Some patients may have sneezing reflex after sampling, and can also be covered with elbow or tissue immediately.

If the operation of throat swab nucleic acid test sample collection is not standardized, it may lead to “false negative” results and delay the treatment of patients.

So, what is the key to the collection of throat swab nucleic acid test specimens? Tian Peng, the deputy chief physician, said that the depth of the collection and the duration of contact with mucosa were the key factors for the collection of nasopharyngeal swabs and oropharyngeal swabs. If the nasopharyngeal swab is not collected to the depth of the nasopharynx cavity, and the patient’s vomiting reaction is large when collecting oropharyngeal swab, the sampling time is not enough. At this time, most of the cells collected are virus-free cells, which may cause “false negative” nucleic acid detection.
