With the occurrence of epidemic in our country, doing nucleic acid is like a daily routine for everyone, it feels easy for us to do nucleic acid, in fact, if the opening of sampling swab is not standardized, it will also affect the results of nucleic acid sampling and testing, so what is the correct way to open the nucleic acid sampling swab?

If, when sampling, the sampling personnel use the following chart sampling, you can determine that the sampling is not standardized, may cause the risk of cross infection or false positive.

The correct way to take a swab.

Swabs are taken with openings as follows.

Easy to cause sampling irregularities for the following reasons.

Swab in the process of removal, the two layers of packaging is not strictly separate (strictly separate see above the correct way), and even some adhesion, so that the swab head may wipe to the swab outer packaging, the outer packaging is exposed to the sampling environment as well as the production and transportation process, the outer surface will have some microorganisms or new crown virus, non-standardized take swab will cause a certain risk of infection.

According to the sampling site, the swab is divided into pharyngeal swab and nasal swab, the pharyngeal swab is coarser and the nasal swab is finer.
