Nasal Swab Pcr Test
To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.
This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.
Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.
For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:
1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.
2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.
3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.
4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.
5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.
In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

About Nylon Flocked Nasal Swab
Cell medical produces a special flocking swab for coronavirus collection, which has excellent sample collection and release ability, can quickly adsorb micro samples, and has a high release timeliness rate. The increase of the number of targets is helpful to improve the sensitivity of rapid diagnostic test.
COVID-19 nucleic acid detection is one of the criteria for the diagnosis of cases. It is the key to early detection, early diagnosis, early isolation and early treatment, as well as the basis for isolation treatment of infectious source and medical observation of close contacts.

Nasal swabs PCR test process
At present, most virus nucleic acid detection kits use fluorescence quantitative PCR to determine whether the sample contains virus nucleic acid by detecting the accumulation of fluorescence signal. So, what steps do nucleic acid detection need to go through? To sum up, there are five steps: sampling, sample retention, preservation, nucleic acid extraction and computer detection.
sampling
Collect human secretions. Wipe the nasal cavity or posterior pharyngeal wall and bilateral tonsils with nasopharyngeal swab or pharyngeal swab
Sample retention
Immerse the swab head into the cell preservation solution, and tighten the tube cover immediately after breaking the tail
preservation
Put the sample tube into a sealed bag, keep it and send it for inspection in time
nucleic acid extraction
Send the sample to the laboratory for nucleic acid extraction
On machine detection
The extract was amplified by fluorescent PCR
