Nasal swab test

We used pharyngeal swabs to collect samples from nucleic acid samples. They are “nasopharyngeal swab” and “oropharyngeal swab”.

Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth. And nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

Nasopharyngeal swab sampling process

Oropharyngeal flocked swab sampling process

The pharynx includes nasopharynx, oropharynx and pharynx, all of which belong to the field of upper respiratory tract.The sampling methods of nasopharyngeal swab and oropharyngeal swab are different.

PCR test can collect nasopharyngeal swabs, sputum and other lower respiratory tract secretions, blood, feces and other specimens for testing, nucleic acid detection by New Coronavirus.If its specimen nucleic acid is positive, it can clear the virus infection.

New Coronavirus infection mainly invades bronchial epithelial cells and alveolar epithelial cells. Lower respiratory tract specimens, such as sputum and airway extracts, more accurately reflect virus infection.

Advantages of nasal swabs

More specimens can be obtained by staying in the pharynx for a long time, which is also the reason why the positive rate reported in the literature is higher than that of oropharyngeal swabs.

DNA flocking swab is suitable for human and animal use. It has advantages over other DNA samples in design. Its unique sample matrix and rapid release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilized with ethylene oxide and passed the detection of human DNA contamination.

Flocking DNA oral test is specially used to improve the yield and quality of genomic DNA in oral test cells. Oral cell sample is a good non-invasive collection and detection method instead of blood. Combined with DNA separation and stabilization kit, it can quickly collect high-purity and complete DNA samples.

French Prime Minister Fidel Castel introduced the situation of the French epidemic at a press conference on the 12th.

Two weeks later, France formed a new epidemic prevention committee to evaluate the outbreak of the blockade.

At a press conference held at 18:00, French Prime Minister Castel said that some indicators showed that the epidemic situation in France had improved, but it was not suitable to relax restrictions.

According to the report of Figaro newspaper, Castle said the outbreak of COVID-19 had a great impact on human health. Now 1/4 of Frenchmen die in COVID-19. So that all those in need can get treatment.

However, the restart of the blockade has achieved results, and the daily new patient curve slowed down within a week, down by about 16%. That could be the turning point of the outbreak. Next week, the medical system may reach the second peak of the outbreak. After that, the number of hospitalized patients will decrease.

Jean Castel warned that the improvement in current epidemic data should be explained in a “positive and cautious” way. Lifting restrictions is irresponsible.

The current restrictions will be maintained for at least 15 days, including the prohibition of non essential transactions, and the continued closure of restaurants and stadiums.

Castel stressed that the government does not want to repeat the blockade measures for the first outbreak of the epidemic this spring, which has led to the stagnation of the country’s economic, social and educational life.

The results of the second blockade will meet expectations. Next, the government will continue to provide large-scale support to enterprises and job seekers. The solidarity foundation will issue unemployment benefits as soon as possible and extend them after they expire. The university town will also mobilize to help poor students and create 1600 student employment opportunities in November, December and January 2011.

Carry forward the spirit of citizenship and make unremitting efforts during the blockade.

At the same time, the authorities asked the Ministry of the interior to strengthen supervision, especially in major cities such as Paris. The French can spend Christmas and year-end holidays with their families. He stressed that he hopes this rule can reach some strict restrictions. It is impossible to expect dozens of people to get together or hold a large celebration on New Year’s Eve.

At the press conference, French health minister Olivier viran, education minister Branke blanch, labor minister Elizabeth Bruno Bernard and economic minister Bruno lemier attended the press conference.

Olivier walan says the epidemic has improved. For the recently discussed new crown vaccine, he said cautiously that there were not all the data. “We are ready to start vaccination as soon as the vaccine is effective and safe.
