Where's the nucleic acid test swab? 1. Swallow swab: The swab will go deep into the posterior pharyngeal wall, tonsil recess and lateral wall for nucleic acid detection, and collect respiratory tract samples, mainly throat swab samples (throat swab 1 minute rapid sampling).
After the subject sat down, he tilted his head back and opened his mouth. The examiner fixed the tongue with a tongue depressor; The swab passes through the base of the tongue to reach the posterior pharyngeal wall, tonsil recess, lateral wall, etc. , repeatedly wipe or rotate 3 ~ 5 times; Collect mucosal cells, avoid contact with tongue, oral mucosa and saliva, and finally insert the swab head into the virus sampling tube.
The process of throat swab collection is fast (only a few seconds) and the pain is less, but some people may feel nausea and vomiting, while others have no obvious reaction.
2. Nose swab: Inserting a long cotton swab into two nostrils for sampling may make people uncomfortable. Mainly insert the cotton swab into the nose and palate in the nasal passage, stay for 15-30 seconds, and slowly rotate to the exit. The discomfort caused by nasal swab sampling is different. On the whole, it's just a little uncomfortable.
There is no fixed depth for nucleic acid detection of how many centimeters a cotton swab walks. Generally, it goes deep behind the base of the tongue and samples are taken from the posterior pharyngeal wall, tonsil recess and lateral wall. The specific depth varies from person to person. For example, children will be shallower and adults will be deeper.
At the inspection window, the fully armed nurses wash their hands with disinfectant first, and then take out a cotton swab about 15 cm long from the packaging bag. This kind of cotton swab used for nucleic acid detection is also called throat swab.
"Ah ..." The confiscated person spoke. The nurse skillfully rubbed the cotton swab into his throat, then held the sampling tube in her left hand and inserted the sampled cotton swab into the sampling tube in her right hand. Knock the cotton swab head into the sampling tube with gentle force and seal it, then discard the long cotton swab into the yellow medical waste box.
How to detect nucleic acid novel coronavirus nucleic acid detection is the most convenient and quick detection method in novel coronavirus. Before the examination, the patient should keep his head intact, remove the secretions on the surface of the nostril, gently wipe the nasal cavity with a cotton swab and enter the nasopharynx, stay for a few seconds to absorb the nasopharyngeal secretions, then gently take them out and send them to the prosecutor's office for training. A new type of pneumonia is lung inflammation caused by novel coronavirus infection. It is highly contagious. So do a good job of isolation and keep a distance from others.
Before the examination, the cotton swab is mainly inserted into the nasal cavity, slowly enters the nasopharynx, absorbs the secretion of the nasopharynx, and sends it to the laboratory to prepare a special delivery medium. You must keep a certain distance from others during the exam. It is best to wear a mask before and after the examination to prevent asymptomatic patients from being infected. If novel coronavirus is diagnosed, it is necessary to cooperate with the doctor for treatment. During the treatment, you need to isolate others. At the same time, diet should strengthen nutrition and improve body resistance.
