After reading the news, some people do not understand: what is meant by "positive pharyngeal swab"?

This is a confirmed diagnosis or undiagnosed

 

Don't panic, we'll explain it in a simple scientific way.

 

 

What does a positive pharyngeal swab mean?

 

First of all, we know that the structure of the virus is very simple: a piece of DNA (or RNA), outside a layer of protein. The DNA or RNA is collectively known as nucleic acid. Nucleic acid can determine the virulence, infectivity, vitality, etc., is the most accurate marker to distinguish each virus.

 

To check the virus depends on the nucleic acid test. The nucleic acid is divided into two forms, RNA and DNA, we humans are DNA as the genetic material, DNA is a double helix structure, with stability, RNA is a single-stranded structure, the structure of the organism is prone to mutation, the new coronavirus is an RNA virus, the surface of this virus is very many raised spines, according to the shape of the virus is classified as coronavirus.

So how to test your body for viral nucleic acids?

 

 

Have to rely on it: nucleic acid detection virus sampling swab

 

 

Detectors will use a cotton swab in your throat to rub a swab, so that you can collect a mixture of bacteria, viruses, human cells and other secretions samples, which is called the throat swab.

 

Then the tester will transfer the sample to a test tube, add some reagents, peel back their coat and extract their nucleic acids, and if the throat swab is positive it means that the infection is viral.

 

Now we know the role and importance of the throat swab.

 

 

An accurate test result depends on a good sample, so what are the materials of our current sample collection swabs?

 

Early sampling swabs have wooden handles consisting of cotton swabs, swabs are natural cotton, unscreened natural materials can lead to pseudostructures, formaldehyde in the wooden rod will also inhibit the growth of microorganisms, preservation solution are saline, this is the first generation of sampling swabs; later sampling swab rod into plastic, but due to the fiber structure of the swab collection and release is very limited, trace samples are difficult to collect, collection The backwardness of the tool also affects the results of the test.

 

According to the above limitations of the sampling swab, Shenzhen Huarui Kang Biomedical Technology Co., Ltd. launched the third generation of new material sampling swab.

 

Shenzhen huarakang product uniqueness advantage

 

1. Shenzhen huarikang sampling swab rod handle using advanced HIPS material, the rod requires pure white, can not have yellowing phenomenon, compared with 99% of the domestic ABS material rod, ABS material rod more prone to yellowing, irradiation is very easy to break, huarikang sampling swab rod handle hold unique stability.

 

2. Swab head fluff is white, not yellow, flocking glue in accordance with production requirements using environmentally friendly water-based glue, glue latex-like, dry thickness of not less than 20 silk, to ensure that sampling swab fluff can be inserted at right angles to the glue layer and ensure the amount of fluff, no VOC emissions, compared with domestic manufacturers use solvent-based glue, Huarui Kang swab has a stronger absorption force.

 

3. Huarui Kang sampling swabs shipped, need to go through ultrasonic water washing to ensure that the swab is clean and not hair removal. Can avoid sampling swabs due to irregularities caused by the health and safety of sampled personnel.

 

4. Its supporting "magic cover" virus sampling tube, with national patent technology authorization, swab using a special design of the break point, so that the swab into the test tube can be inlaid with the tube cover as one, saving steps, one step faster.

 

This swab is not only suitable for human virus nucleic acid detection, good siphon effect is more applicable to the recent national cold chain food nucleic acid testing full coverage of the action to.

 

In addition to efficient sample collection, Shenzhen Huarakang pharyngeal swab for different situations on multiple occasions, designed a variety of convenient packaging.
