nasal swab

For the need of our Chinese general population enterprises, do nucleic acid with epidemic prevention and management policy is inevitable. Then the problem of frequent nucleic acid sampling, was swabbed so can many times, are you able to know the medical staff through the specific poke is where? Is it the side walls of the mouth or tonsils, or affect the entire throat are rubbed?

First of all, the most prominent meatball in our mouth is called the uvula, behind the uvula is a depressed area on both sides called the tonsil fossa, which contains the tonsils. He swells up when he's inflamed. For a nucleic acid sample,Rapid antigen nasal swab the doctor wipes a cotton swab back and forth over the sides of the tonsils at least three times, then pushes the swab all the way to the innermost part of the mouth called the posterior pharyngeal wall, where after wiping at least three times the swab can be removed and the test tip dipped into a tube of virus-preserving solution.

Of course, during the time when the virus first appeared or where controls were tighter, a large percentage of people experienced nasal swabbing, which felt like the swab was poking right into the soul and stabbing into the brain. The nasal swab enters through the nostrils and slowly penetrates along the bottom of the inferior nasal passage. Since the nasal passage is not a straight channel and has a certain curvature, the entire swab material for nucleic acid sampling should be soft and deformable, and it should not be used with force during penetration, or bleeding may result. When the swab encounters resistance and cannot be inserted, it means that the tip of the swab touches the back wall of the nasal cavity. What you may not realize at this time is that the length of the swab is much longer than you think. Then gently turn it around and slowly remove the swab, breaking off the tip and placing it in a test tube of virus preservation solution.

As in the case of the new coronavirus infection introduced in Daxing District in 2019, anal swabs are also available for those who do not wish to receive a nose sample. A sterile swab is slowly inserted 3 to 5 centimeters into the anus. Allow the insertion to rotate steadily, then pull it out slowly and immediately place the tip of the swab into a virus preservation tube.

Snuff swabs have a higher detection rate than oropharyngeal swabs, because when an oropharyngeal swab is done, it tends to cause dry heaves and the swab does not actually touch the pharyngeal wall. A pharyngeal swab usually extracts secretions from a person's mouth, which are often affected by diet and water intake and may affect the test results. Nasal swabs, on the other hand, usually extract nasal secretions, which have relatively high viral loads and therefore lower detection rates than snuff swabs, but oropharyngeal swabs are quick and easy to perform and are commonly used for mass screening.
