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.

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

Quick covid test

Quick covid test |How does covid testing work?

Posted on by

A new covid test at home has been authorized by the U.S. Food and Drug Administration (FDA) for emergency use (EUA).

Here’s what you need to know about testing at home.

How can I get quick covid test?

Cell medical’s covid test at home now has a prescription, which means Americans can get one from their health care provider.

If doctors suspect that their patient is infected with covid – 19 within the first six days of symptom onset, they can prescribe a rapid test.

How much does it cost?

Please contact us for more details.

How does testing work?

Rapid Antigen Test is a lateral flow test, a portable covid test that usually returns results faster than the widely used laboratory based PCR test.

It works by detecting nasal swab samples and provides positive or negative results within 10 minutes. The results appear on test strips exposed to nasal swab samples.

The FDA said flocked swab can be collected from people aged 8 and over, but if the tested children are less than 14 years old, it should be collected by adults.

How accurate is the test?

Cell medical claimed that the time when the positive results of the test matched the PCR test was 84.8%, and the negative results matched the PCR test were 99.1%.

FDA said that the negative test results of covid test do not necessarily exclude the possibility of covid – 19 infection.

“and should not be used as the only basis for treatment or patient management decisions, including infection control decisions.

“People who are negative and continue to experience COVID 19, have a fever, cough and / or shortness of breath, may still have SARS – CoV – 2 infection. Follow up care should be sought from doctors or medical staff. ”

Not all side flow tests require the use of prescriptions. On December 15, the FDA issued the EUA for the first outside counter flow covid test at home.

The covid – 19 family test also uses nasal swab samples to detect covid infection and works with people aged 2 years and older.

The FDA said that in the population with covid symptoms, the ellume test correctly identified 96% of positive samples and 100% of negative samples. In the population without symptoms, it collected 91% of positive samples and 96% of negative samples.

Similarly, the FDA said that the negative results of the test do not necessarily exclude the possibility of covid infection.

Broader prospects

According to CDC data, as of Monday, the United States had reported 47.5million cases of covid and 778,316 deaths.

The data also showed that 432 million people were vaccinated on Monday.

What elements should a good sampling swab meet？

2021-11-04

In the collection of virus samples, small sampling swabs are always ignored, and people often ignore the judgment of its quality. However, the sampling swab is the “vanguard” in the whole nucleic acid detection process. It is the first area to contact the virus. It can be said that it controls the “lifeblood” of the whole nucleic acid detection process.

sampling swab-flocked swb

sampling swab-flocked swab

Cell medical (Dongguan) believes that a good sampling swab should have three elements——

1: more samples. That is, the virus samples collected by the sampling swab should be as many as possible.

2: release more. That is, the virus samples collected by the sampling swab should be released into the sampling solution as much as possible.

3: excellent design. That is, the design of sampling swab shall not interfere with the nucleic acid detection in the last link.

It is well known that after large-scale nucleic acid screening, the previously commonly used winding swabs were eliminated, and flocking swabs that are easier to collect release samples were used.

However, it is not enough to unify the material.

The design of flocking swab is also very exquisite in structure.

Different nylon fiber arrangement and density determine the difference of sample collection and release.

A good swab can avoid missing inspection to a greater extent.

We made a comparative experiment according to the effects of temperature and storage time on the preservation of virus.

The experimental results are as follows: the virus can be isolated within 48 hours when the virus is preserved with cell medical virus preservation solution at 2-8 ℃ or room temperature.

Principle of virus collection and precipitation with flocking swab?

The unique structure of the top of the flocking swab can almost completely extract and precipitate a small amount of DNA. Therefore, the flocking swab has more obvious advantages in micro DNA collection.

(1) Sample collection effect is good:

(1)Through the directional wiping effect of brush fiber layer.

(2) More than 95% sample release rate,near surface of the brush fiber is conducive to collecting samples.

(3) The capillary movement between the nylon fibers at the top of the flocking swab forms a strong hydraulic pressure. To absorb liquid or cell samples.
