COVID-19 is an infectious disease,a respiratory disease.

COVID-19 variants_Omicron

The new findings indicate that the new mutation of COVID-19, Omicron, spread earlier than everyone thought, and the scope is wider.

We must do a good job in vaccine injection and virus swab testing is the top priority.
According to the Associated Press, on Tuesday (November 30), the new findings have clearly shown that Omicron has entered many countries before the world has created its own protection system for Omicron.

The Spanish Institute of Public Health Service and Natural Environment (RIVM) detected Omicron in virus samples on November 19 and 23.

According to the World Health Organization, South Africa first reported this type of mutant virus on November 24.

At this stage, it is still not clear where this type of mutation first occurred, nor how infectious it is, but this has not prevented some countries from rushing to implement travel restrictions, especially for tourists from southern Africa.

This measure has been criticized by South Africa, and the WHO has also expressed its resistance, feeling that its actual effect is relatively limited.

The latest developments have also become increasingly clear that the travel ban cannot prevent the spread of new mutations.

The German government stated that they had seen Omicron in a man who had neither been to Africa nor had any knowledge of anyone who had contracted this type of virus.
The World Health Organization reminded on Monday that the risk of Omicron’s worldwide spread is “very high”, and initial direct evidence suggests that it is likely to be more infectious.

The COVID-19 pneumonia epidemic broke out for the first time nearly two years ago, and at this stage, the world’s response at many levels is similar to the disorder two years ago. Including random implementation of travel restrictions, and the lack of grasp of where there are risks and where there are risks.

Senior officials from all over the world try to clear everyone’s fears, saying that their vaccines are still a better way of defense. Be sure to continue to work hard to make vaccination spread all over the world. At the same time, do a virus swab test.

However, regarding the effectiveness of vaccines against Omicron mutations, although the President of the United States is also urging vaccination, the White House President’s medical consultant and the top infectious disease expert in the United States told the ABC TV program on Monday that the experts look forward to one or two in the future. Understand within a week.

What is the maintenance level of the current COVID-19 vaccine against this new mutation? Don’t know yet. But what we can do is to do a good job of virus swab testing and prevention. For example, go out less and party less.

COVID-19 symptoms;

The symptoms of COVID-19 are likely to include dysosmia, high fever, dry cough, dyspnea, chills, headache, muscle pain, sore throat, hematoma, or runny nose. At the same time, it is manifested as conscious fatigue, weakness, and weakness.
This situation may happen 2-14 days after you touch the virus that causes COVID-19.
Not all COVID-19 patients have all of these symptoms, and some people have no symptoms. That is an asymptomatic infection.
Even after recovering from COVID-19, some people are still likely to have unforgettable illnesses, such as fatigue, dry cough, or joint pain. The long-term physical and mental health hazards are unclear, but they may cause permanent damage to the cardiovascular system, lungs, or other human organs. This is more likely to occur in people with more serious illnesses, but it is more likely to occur even in people with milder illnesses.
If you have symptoms, please take a swab. If you have questions or concerns about a medical condition, please consult your health service provider.

How to obtain a nasopharyngeal swab specimen?

Overview.

Nasopharyngeal swab specimen collection of respiratory mucosal surface specimens is a method for the diagnosis of Covid-19 novel coronavirus in adults and children.

This operation can also detect patients with suspected respiratory infections caused by other viruses and bacteria.

There are no special contraindications for nasopharyngeal swab specimens. However, clinicians should treat the following conditions with caution: the recent history of nasal trauma or surgery, severe nasal septum deviation, chronic nasal obstruction, and severe coagulation.

Preparation for nasopharyngeal swab specimen sampling.

The nasopharyngeal swab is a special sampling tool, which consists of a sampling head made of soft plastic or flocked nylon. In addition to nasopharyngeal swabs, operators also need personal protective equipment (PPE) such as isolation gowns, non-sterile gloves, protective masks, and face shields.

Before starting to use, please make sure that all virus sampling tubes are labeled, and the analysis application form is filled incorrectly.

Nasal Swab Sampling Steps

We recommended that patients with suspected Covid-19 type coronavirus infection wear masks.

The patient took off the mask and blew his nose with a paper towel to remove excessive secretions from the nasal passages.

Take out the tissue. Slightly lift the patient’s head so that it can wipe into the nasal passage. Ask the patient to close his eyes to alleviate the slight discomfort caused by the operation.

Along the nasal septum, gently push the swab above the bottom of the nasal passage forward until you feel a sense of resistance indicating that the swab has reached the nasopharynx.
Insert the swab in the nostril parallel to the upper jaw.

If resistance is encountered during pushing the flocked swab, the scraper should be withdrawn, try to adjust the angle and then push again, at the same time closer to the bottom of the nasal passage.

The depth of the nose insertion should be equal to the distance from the nostril to the opening of the external auditory meatus. CDC recommends keeping the sampling head for a few seconds after it reaches the nasopharynx, allowing the sampling head to absorb the secretions, and then slowly rotating the swab to discharge it slowly (people who have done nasopharyngeal swabs will appreciate which kind of sourness Cool feeling). Your institution may also recommend sampling for a few weeks after exiting the spin. Ask the patient to wear a mask.

Nasopharyngeal swab specimen processing.

Open the sampling tube with virus transport medium, put in the flocking swab, fold out the sample tube in the groove, and discard the tail. Tighten the label sampling tube cover, and wipe the sampling tube with a sterile wipe.

Then place the sampling tube in the biohazard bag opened by the assistant. Some departments may require you to put the samples back in their original packaging and then send them for inspection. According to CDC guidelines, process the swab sample directly, or put the sample in a preservation solution or store it at room temperature.

Winter is coming, the cold current is coming, the goose feather like snow is flying all over the sky, and the whole world is wearing a white coat.

Many customers once again throw this “soul question” to us. “Can your Viral Transport Kits adapt to the cold environment?”

He answer is yes. Let’s follow Cell medical Dr. Li for experimental verification!

Experimental purpose

Verify that the Viral Transport Medium of cell medical (Dongguan) Co., Ltd. has no significant impact on its service performance after low-temperature freezing and thawing.

Experimental scheme

Simulate the process of low-temperature freezing during transportation, place the sampling tube in a low-temperature environment for 24 hours, and then melt at room temperature. The sampling tube products stored normally without freezing and thawing were used as the control. Each group was added with virus mixture, stored at 4 ℃ for 24 hours, and then bathed in water at 56 ℃ for 30 minutes for nucleic acid extraction and nucleic acid detection. Set 2 repetitions for each group.

1. Low temperature icing simulation: set two low temperature gradients and place the sampling tube in two low temperature environments of – 20 ℃ and – 80 ℃ respectively.

2. Mixing of virus solution: We used two different concentrations of virus solutions, representing high and low concentration gradients respectively. The copy numbers of virus solution were 106 copies / ml and 104 copies / ml, respectively. Simulate the actual sampling process, add the virus solution in the volume ratio of 1:10 to the sampling solution, and the virus solution is 100 μ 50. 1ml of sampling solution and add 100 ml to it μ L of oral liquid.

3. After mixing each group, place it in 4 ℃ environment for 24 hours and inactivate it in 56 ℃ water bath for 30 minutes.

4. Extract the nucleic acid of each group of virus, and detect the virus content of each group by RT qPCR. The CT value is used as the basis for result evaluation. The higher the CT value, the higher the detected concentration.

5. The experimental groups are as follows:

Main experimental materials

  •   Sampling solution: virus preservation solution produced by cell medical (Dongguan) Co., Ltd.
  •  virus diluent: the virus isolation serum-free medium of Cell medical was used for gradient dilution.

All about the Nasal Swab

Nasal Swab:nasopharyngeal np swab.

The specimens collected from nucleic acid samples are mainly pharyngeal swabs, which are divided into “nasopharyngeal swabs” and “oropharyngeal swabs“.

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.

How to do a nasopharyngeal swab?

A man was doing a nasopharyngeal swab sample

A man was doing a nasopharyngeal swab sample

Nasopharyngeal swab sampling method.

Hold a swab close to the nostril to enter, and slowly go deep along the bottom of the lower nasal tract.

Since the nasal tract is curved, do not use too much force to avoid trauma and bleeding.

When the top of the swab reaches the posterior wall of the nasopharyngeal cavity, rotate it gently for one week (stay for a moment in case of reflex cough), then slowly take out the swab and immerse the swab head into a tube containing 2 ~ 3ml virus preservation solution.

About Nasal swab sample collection.

How to take a swab sample?

Ask the patient to take off the mask and blow his nose with a paper towel to remove excess secretions from the nasal cavity. Remove the swab from the package.

Tilt the patient’s head back slightly to make the nasal passage easier to pass through. Ask the patient to close their eyes to reduce the mild discomfort of the operation.

Gently insert the swab over the bottom of the nasal canal along the nasal septum until the nasopharynx stops when resistance is felt.

Insert the cotton swab parallel to the upper jaw into the nostril.

If you feel resistance when passing, step back and try to reinsert it at another angle to bring it closer to the bottom of the nasal canal.

The depth of the swab should be equal to the distance from the nostril to the opening outside the ear.

CDC recommends placing the swab for a few seconds to absorb enough secretions, and then slowly removing it while rotating the swab.

Some organizations may also recommend rotating the cotton swab several times before taking it out.

After removal, ask the patient to put on the mask again.

Specimen processing

Open the virus transport medium and insert the swab into the collection tube.

Break the swab at the groove and discard the remaining part. Seal the labeled collection tube and place it in the biohazard garbage bag.

According to convention, you can return the sample to its original packaging for disposal.

Follow CDC instructions for direct treatment of swab specimens or place swabs in medium with or without refrigeration.

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.

Quick covid test Rapid Antigen Test Kit Nasal Saliva Test at home

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.

Whether nucleic acid detection or virus detection.

Universal Transport Medium (UTM) and NP Flocked Flexible Swab sampling swab play a great role.

NP Flocked Flexible Swab : Used to collect virus samples.Nasopharyngeal sample.

While virus preservation solution plays the role of preserving these virus samples.

which not only ensures the integrity of nucleic acid virus, but also facilitates the later detection accuracy.

How many Universal Transport Medium are there? What are the functions and differences?

At present, there are two kinds of Universal Transport Medium on the market, namely inactivated virus preservation solution and non inactivated virus preservation solution.

Inactivated Virus Transport Medium :Use to lyse and inactivate the virus.

It can protect the tester from the second infection of the virus.

Stored at room temperature for a relatively long time, saving the cost of virus samples and transportation.

The purpose of non inactivated virus preservation solution is to retain the protein shell of the virus and the nucleic acid DNA or RNA of the virus, so as to ensure the integrity of the nucleic acid of the virus sample in the process of submission for inspection.

Although there will be a certain infectious risk in case of misoperation, this preservation solution maintains the originality of the virus sample to the greatest extent and is a cultured virus transport medium.

Noted:long-term storage requires strict low-temperature storage after sampling.

Relatively speaking, the non inactivated virus preservation solution has higher requirements for the laboratory, higher sensitivity and more applications. But it is relatively easy to be infected.

As long as there are no problems in sampling and detection operations, there will be no risk problems.

How to select inactivated and non inactivated virus preservation solutions cannot be generalized, We should choose according to different needs, and the price determines the quality.

Don’t be greedy for small things and lose big ones.

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.
