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?
Based on the sampling consumables market in the field of biological diagnosis, Shenzhen Huarikang Biological has developed disposable sterile sampling swabs, disposable gynecological sampling swabs, disposable virus sampling tubes, saliva collection devices, disinfection swabs, disinfection applicators and other products that are suitable for human use.
Antigen self-test nasal swabs, also known as nasal front swabs, also known as anterior nasal swabs, sampling is simple, low operational professional requirements, better comfort, so the new crown antigen self-test more nasal swab sampling.
Shenzhen Huarui Kang biological disposable sponge material swab (anterior nasal swab) using sponge hot pressing process, product design ergonomic, sponge material soft characteristics, will not cause harm to the human anterior nose, and in the human nasal cavity after sampling sponge release rate than the traditional flocking is about 35% greater, to ensure the sensitivity and accuracy of the rapid detection of antigen, while there will be no lint residue in the nasal cavity.
Shenzhen Huarui Kang biological class II sponge antigen swab, the release rate of sponge material after sampling is about 35% greater than that of flocking, in order to ensure the sensitivity and accuracy of rapid antigen detection, while no fibrous hairs will remain in the nasal cavity. The current use effect has been recognized by many domestic listed antigen reagent manufacturers;
Shenzhen huarikang biological disposable sampling swab has a variety of types, can be applied to the disease control, clinical and scientific research on infectious pathogenic microbial detection sampling, different specifications, material swabs can meet the needs of a variety of scenarios.
Shenzhen huarikang biological disposable sampling swab swabs are made of safe materials, high quality, in line with standards, large collection and release of samples. The rod is made of special fragile material that does not produce micro-debris.
Features:
higher sampling rate
faster and more complete sample release
improved diagnostic sensitivity
easy to handle and transport.
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.
First: the swab packaging is not qualified, as shown below, the swab head at the opening, if opened from the opening, the swab head first exposed, for such sampling swabs shall not be used.
Second: sampling personnel for quick and easy, here to all sampling personnel, they are really hard work, but also may not be sampling training in place.
Causes of cross-infection or false positive risk.
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.
