During an outbreak, everyone should be familiar with sampling swabs. When doing nucleic acid, touching the nose and throat is directly touching the sampling site of human organs, that is, directly touching our human organs. Therefore, the material of the sampling head will affect our comfort and is closely related to the subsequent detection.
Sampling swabs should be polyester, nylon and other non-cotton, non-calcium alginate swabs, and the handle should be non-wood. The breakpoint is located about 3cm from the top of the swab head, which is easy to break.
NASAL FLOCKED SWAB
Moreover, the experimental analysis shows that the extraction efficiency of nylon flocked swabs is the highest. In contrast, the recovery efficiency of nylon flocking swabs is also higher than that of other material swabs.
Nylon fibre flocking technology. The front end is coated with vertically fixed nylon short fibers, so that the entire sampling area of the sampling swab has no absorption holes, and the sampling sample will not be scattered in the fibers, which is conducive to faster and more efficient sampling!
Compared with traditional winding swabs, nylon flocking swabs collect and release 3 times the number of samples, do not damage cell samples, ensure the survival rate of cell samples, do not leave fatty acids, do not affect the test and detection results, not to mention Said to cause harm to the human body.
What materials cannot be used for sampling swabs?
As we all know, the materials of medical swabs have always attracted much attention. After all, medical swabs come into direct contact with the skin. People who touch the skin can first touch alcohol for disinfection, that’s fine, but what about those who have direct contact with organs? For example, the throat swab we are most familiar with during the epidemic.
The throat swab is in direct contact with the sampling site, and the material of the sampling head is closely related to subsequent testing. The sampling swab head should be made of nylon flocked swabs or rayon, and calcium alginate sponges or wooden stick swabs (including bamboo sticks) should not be used.
Cotton products should not be used for the swab head, because the cotton fiber has strong adsorption to protein and is not easy to clean into the subsequent storage solution; wooden.
What are the types of swab tests?
There are two different types of COVID tests – Swab tests and antibody tests.
1. Swab tests can show if you have an active coronavirus infection and should take steps to isolate or isolate yourself from others. There are currently two types of diagnostic tests – molecular (RT-PCR) tests that detect the genetic material of the virus, and antigenic tests that detect specific proteins on the surface of the virus. Samples are usually collected with a nasal or throat swab, or saliva spits into a test tube.
2. Antibody tests look for antibodies that the immune system produces in response to a threat, such as a specific virus. Antibodies can help fight infection. Antibodies can take days or weeks to develop after infection and may remain in the blood for several weeks after recovery.
Therefore, antibody tests should not be used to diagnose active coronavirus infection.
Right now, researchers don’t know whether the presence of antibodies means you’ll be immune to the coronavirus in the future. While there is a lot of uncertainty surrounding this new virus, the widespread availability of antibody testing and clinical follow-up over time also has the potential to provide the medical community with more information about whether and how long a person has recovered from the virus of people have a reduced risk of infection if they are re-exposed to the virus.
