Sample Collecting Flocking Medical Nasal Swab

How much do you know about flocking sampling swabs
Flocking swab definition
Flocking swab adopts spray dense planting nylon fiber technology; The sample volume collected and released is three times that of traditional swabs. Ensure the survival rate of cell samples, no residual fatty acids, and will not affect the test results.
Why use flocking cotton swabs?
Covid-19 is a variant of novel coronavirus, which can cause pneumonia after human infection. It is an acute respiratory infectious disease, which is highly infectious and susceptible to ordinary people. It is easy to replicate in human upper respiratory tract. Generally, covid-19 can be detected rapidly within 96 hours after infection. Testers can find viruses in human upper respiratory tract. Experiments show that flocking swabs can quickly elute >95% of the original samples and easily improve the detection sensitivity.
Application of sampling flocking swabs.
The upper respiratory tract of human body includes nasal cavity, pharynx and throat. In other words, if a person is infected with covid-19, he can extract viral nucleic acids from the nasal cavity, pharynx and throat within 96 hours. Therefore, we usually sample these locations when we conduct rapid detection of covid-19.
We distinguish swabs by different sampling positions. For nasal sampling, we become nasopharyngeal flocking swabs; For oral sampling, we call it oropharyngeal flocking swab.
Why should we use a sampling swab instead of an ordinary Cotton Swab to make nucleic acid?
The sampling swab looks similar to an ordinary cotton swab, but the top is actually a flocking swab. Its material is polyester or nylon fiber, which is similar to the bristles of toothbrush. The flocking swab is made of nylon fiber flocking technology, and the front end is coated with nylon short fibers fixed vertically, so that there are no absorption holes in the collection area of the whole collection swab. In this way, the collected samples will not be dispersed and retained in the fiber, which is conducive to faster and more efficient sample elution.
What is the composition of the sampling swab cotton swab used for nucleic acid?
The sampling swab cotton swab used for nucleic acid is mainly composed of nylon short fiber Velour hair and medical grade ABS plastic rod. Nylon short fiber acts like a soft brush, which can effectively improve the collection of cell materials; The capillary movement between fibers forms a strong hydraulic pressure, which absorbs the liquid sample; At the same time, the sample is close to the surface of the swab and easy to elute.
