what is a flocked swab

Many customers ask me, why is use flocking sampling swabs? You’ll know from the comparison below：

The flocked sampling swab of cell medical (Dongguan) Co, Ltd. is composed of nylon short fibre velveteen wool head and medical-grade ABS plastic rod. The volume of samples collected and released is 3 times higher than that of traditional swabs.

Ensure the survival rate of cell samples, no residual fatty acids, and will not affect the test results.

The sampling swab set contains a swab and a cell preservation solution. After collecting samples with swabs, we stored them in a liquid-based cell preservation solution. It ensures the integrity of sample DNA,

How are flocked swabs made?

Made of nylon fibre flocked technology, and the front end with nylon short fibers fixed in a vertical manner.

So that there is no absorption hole in the sampling area of the sampling swab.

The sample we obtained with a cotton swab does not disperse and remains in the fiber

Which is beneficial Faster and more efficient elution.

Traditional cotton swabs cannot completely collect and elute samples while flocking swabs can elute 95% of samples.

Therefore, the use of flocked swabs has great advantages for various sample collection applications.

What is a flock nylon swab?

Nylon flocking sampling swabs are specially used for sample collection.

And cotton swabs can also be used for sample collection, but the number of samples collected and the collective effect of the two cannot be compared.

Flocked nylon swab with outstanding sample collection and release capabilities.

It can quickly absorb trace amounts of samples, and the release efficiency is high.

The increase in the number of targets helps to improve the sensitivity of rapid diagnostic tests.

product features:

flocking swab has a good sampling effect, and the sample collection amount and release amount are as high as 95%;
our unique technology increases the comfort of the collected;
ethylene oxide sterilization has no inhibition on the subsequent application;
swab using spray dense planting nylon fiber technology;
nylon fiber swabs can better collect clinical samples and immediately release them into the liquid delivery medium.
It has an ABS rod with a “breakpoint“.

In short, the upright nylon fiber is like a soft brush, which can collect more cell samples. Nylon flocked swabs can absorb and release more samples.

Nasal swab test

Posted on 2021年8月25日2021年8月25日 by Dr. Lee

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.

The French epidemic ushered in an inflection point, and current restrictions are not relaxed

At the turning point of the outbreak of covid-19 in France, the current restrictions have not been lifted.

According to thr overseas network, the epidemic situation in France has reached a turning point.

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.

activity

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.
