Cell medical Confirm COVID-19 Diagnostics Cover Omicron Variant

Cell medical Corporation has announced that its established CE-IVD marked Iclean® SARS-CoV-2 flocked swab real-time multiplexed PCR assay reliably detects all SARS-CoV-2 variants.

And in addition, is expected to also provide a clear indication of Omicron (B.1.1.529), recently declared a ‘variant of concern’ by the WHO.

Iclean® SARS-CoV-2 flocked swab is a multiplexed CE-IVD marked PCR assay for the detection and quantification of all major SARS-CoV-2 variants, based on Cell medical´s proprietary technology.

In addition, the assay simultaneously detects the S-gene mutations Del69-70 and N501Y, which are expected to be clear indications that the variant is Omicron (B.1.1.529).

The new Omicron variant shares these mutations with the Alpha variant (B.1.1.7), but the Alpha variant is meanwhile of low epidemiological interest and only gets detected sporadically.

Accordingly, by identifying Del69-70 and N501Y, the laboratory has an indication that the sample most probably is the SARS-CoV-2 Omicron variant.

This can subsequently be confirmed by genomic sequencing, as is standard practice.

The Iclean® SARS-CoV-2 flocked swab also provides a viral load result according to WHO standard (IU/ml), as well as CP values and easy interpretation of mutations.

The test is validated for use with nasopharyngeal and oropharyngeal swabs and contains reagents for 96 reactions.

Sample extraction, amplification, and PCR results are available in under 3-4 hours.

Using the Iclean® SARS-CoV-2 flocked swab assay allows the user to run a screening tool for detecting SARS-CoV-2, viral load, and an early indication of the Omicron variant.

Moreover, Cell medical is pleased to confirm that their full range of other Iclean® SARS-CoV-2 assays is also expected to reliably detect the Omicron variant (B.1.1.529). These assays include:

* Not for Sale in the USA
** Not for use in clinical diagnostics procedures

All our SARS-CoV-2 assays are CE-IVD-labeled according to the European IVD Directive 98/79/EC.

And mainly sold into European Markets.

As we learn more about COVID-19,

Protect yourself and others: COVID-19, do a new crown swap test and get a new crown vaccine.

On this page, you will learn:
What should we pay attention to during holiday gatherings?

Of course, Cell Medical recommends minimizing unnecessary gatherings. For you and your family and friends.

The latest mutation of the new crown epidemic has increased the risk of transmission.

Faced with the epidemic, but the company arranges to travel, what should I do?

Please do a nasopharyngeal swab test before going home.

About nylon flocked nasal swab

What should we pay attention to during holiday party activities?

Cell medical company offers a variety of ways to enjoy the holiday tradition and protect your health.

We encourage colleagues in the United States to take the following steps to make your holiday gatherings safer.

To do a nasopharyngeal swab test, maybe we have to confirm whether we have been to a high-risk area before the party. Whether to carry the new crown virus, a flocking nasopharyngeal swab test is the best choice.

Take a COVID-19 swab test so you can find out before you go. You can go to the test site or use the home test program. Of course, we recommend that you go to a professional testing agency for nasopharyngeal swab testing.

Some locations may be closed on or around holidays. Check it a few hours before departure.

vaccination. The best way to ensure the safety of your family and friends is to get vaccinated if you and your family are eligible.

If you feel unwell, please stay at home. If you have symptoms of COVID-19 or a positive swab test, please stay at home and away from others. And notify the government personnel of the first pass to conduct another virus test, and do not attend the party.

Of course, nowadays, you must wear a mask before going out. This is for the health of you and your family and friends.

You need to wear a mask when taking public transportation, including buses and airplanes.

Of course, party us

Gather in an outdoor or well-ventilated place.

According to experience, the most likely way of transmission of the virus is through saliva or droplets. Therefore, during the epidemic period, try to avoid contact with others and face-to-face conversations.

During the party, we should pay attention to eating clean cooked food and boiling water.

Ask the party host to try not to choose to eat some wild, uncommon, and strange food.

At the same time, the weather is volatile, and your handsome colleagues pay attention to adding or removing clothing.

Finally, Cell Medical recommends minimizing unnecessary gatherings.

The latest mutation of the new crown epidemic has increased the risk of transmission.

Infectivity may increase by 500%! Powerful mutant strains broke out in various countries in the world!

On the 27th local time, several countries and regions, including the United Kingdom, Germany, Italy, and Israel, discovered the new variant “Omicron” (Omicron) of the new crown.

At this stage, countries around the world have tightened their epidemic prevention measures at different levels.

The Israeli government announced that it will gradually prohibit all foreigners from entering the country on the evening of the 28th local time. Resolutely putting an end to the spread of the “new coronavirus mutant strain Omi Keron” has become a new starting point for epidemic prevention worldwide.

Authoritative American experts think: “The infectivity of the new mutant strain may increase by 500%.”

On November 27, WHO announced that the new mutant strain discovered in South Africa was named Omicron.

On the 26th local time, the Federation of American Scientists emphasized that in comparison with the Delta mutation, the total number of “bad thorn gene mutations” in the new mutation was twice that of Delta.

“The B.1.1.529 variant is likely to have a strong charisma of 500%, which is by far the most surprising statistic.”

On the 26th local time, the United States announced that it will gradually restrict the citizens of South Africa and seven other non-US African states to travel to the United States from the 29th.

Previously, the United Kingdom, the European Union, and many other places have called for the suspension of flights originating from African countries.
The new mutant new coronavirus “Omi Keron” first discovered in South Africa has spread rapidly

According to foreign media reports, in Gauteng Province, where the population of South Africa is more concentrated, 90% of the recent increase in virus cases is related to this strain. The Israeli Ministry of Health issued a statement on the 26th stating that the first case of “Omi Keron” virus infection was found. The case came from Malawi, Africa, my country. The Belgian Minister of Environmental Health, Van den Brock, confirmed that the host country has found the infection case of the mutant strain “Omi Keron”. According to reports, this is also the first diagnosed case in Europe.
The first case of Omi Kiron strain infection occurred in Italy…

The spread of new mutant strains is astonishing, which has aroused great vigilance in all countries!!!

Facing the epidemic, but the company arranges to travel, what should I do?

Of course, the best option is to refuse a business trip. But often this is not something we can decide.

Everyone is based on the following suggestions to alleviate the spread of COVID-19 to protect themselves and others.

The more processes you use to mitigate the spread of COVID-19, the safer you will be. When it comes to avoiding the spread of COVID-19, no step is perfect.

1. Reduce your risk of COVID-19

2. Actions and natural environment maps with lower risk and higher risk.

3. Proposals for participants and theme event planners: COVID-19

Vaccination. The COVID-19 vaccine is one of the appropriate ways to avoid being infected or spreading COVID-19.
If you are not vaccinated (including children)

Maintain a minimum distance of 6 inches from people from other homes.
When you cannot maintain a 6-inch distance from others, please wear a mask in the room and outdoors.

If you are vaccinated or not vaccinated, Cell medical strongly recommends that you:

1. Wash your hands frequently, maintain your hygiene, and open windows every day for ventilation

2. Try not to go out, if you go out, try to wear a mask

3. Try not to hold parties and avoid contact if it is not necessary

4. Pay attention to eating habits, eat more fruits and vegetables, exercise, and keep a good sleep

5. Cover your nose and mouth when sneezing, and don’t spit anywhere

If possible, work from home.
Clean and disinfect the surface.

Please do a nasopharyngeal swab test and isolation work before going home. For the health of you and your family.

Virus Test For COVID-19

In this article：

Swab Test;

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.

About COVID-19 Swab Test

The new crown virus has mutated continuously.

From Delta to Omi Keron, the COVID-19 virus has continued to mutate, and the global epidemic is prevalent at a high level.

Canada announced that all entry personnel from all countries except the United States are required to be tested for the new coronavirus.

At this time, whether you are leaving the country or entering the country.

I even worry or doubt whether I have contracted the coronary disease.

Perhaps understanding the new coronavirus test has become a compulsory course for most people.

What is the new crown swab test, how to collect a nasopharyngeal swab? Is nasal swab sampling painful? If your test result is positive, what do we need to do? Why do most virus tests choose to flock swabs? Is nasopharyngeal swab accurate? Should you be tested for nasopharyngeal swab samples?

We talked with Dr. Li of Cell medical to learn more.

What is the COVID-19 test and what are the test methods?

Nucleic acid detection (RT-PCR Test) method, antibody detection, and antigen detection.

A swab test simple, effective, and fast way to detect COVID-19.

Including nasopharyngeal swab testing and oropharyngeal swab testing.

Medical staff will use flocked swabs to take samples from the nose and throat and put them into the virus sampling tube.

There are two types of swab sample testing: molecular test (PCR) and antigen test.

How to perform a COVID-19 nasal swab test?

The COVID-19 nasal swab test involves inserting a 6-inch flock (a long stick with a very soft brush) into the cavity between your nose and mouth (nasopharynx).

The medical staff inserts the flocking swab into each nostril for about 15 seconds and rotates it several times to collect enough samples for testing.

The samples are then sent to the laboratory for testing, and our test results are usually known within or within the next day

Since the nasopharynx is in a sensitive position of the body, it will produce a lot of very strange sensations.

On the one hand, the swab is inserted deeply into your nose and it irritates the lacrimal glands.

At this point, you don’t know if you are moved to tears or you are crying in pain.

The nasal swab test is not very painful, but it is very uncomfortable. Some people may have nausea during the nasopharyngeal swab test. Nasal swab painful.

Because the swab will also touch the back of your throat, this reaction is normal.

Whether it is tearing or nausea, nasal swab testing is a common phenomenon.

Don’t worry, everything is normal.

Are there other types of COVID-19 swab test methods available?

Yes, an oropharyngeal swab is one of the options.

Of course, if you want to experience another feeling, an anal swab test is also a good choice.

But they are not as sensitive as the COVID-19 nasal swab test.

Israel’s development of the new coronavirus “saliva detection method” saliva detection still needs scientists to confirm on a larger scale. There is no conclusion yet, but it is promising.

In addition to nucleic acid testing for the detection of viral genetic material, there is also antigen testing.

Currently, nasal swab testing for COVID-19, including nucleic acid testing, is still the best choice.

How about the covid test kit at home? Are their results reliable?

The home covid test kit sounds very attractive.

Home covid test usually refers to individuals collecting samples of themselves or their family members through sampling swabs.

We put the collected samples in test tubes with a virus transport medium, and then transport them to the testing facility.

Although you can use the Home covid test kit to test COVID-19 safely and comfortably in your own home.

However, Dr. Li suggested that it should be carried out at a professional testing institution.

Because the quality of the samples we collect and the integrity of the samples during transportation will affect the sampling results.

How accurate is the nasal swab test for COVID-19?

How to obtain a precise nasopharyngeal swab specimen?

Polymerase chain reaction (PCR) uses a piece of DNA as a template.

Then, with the participation of DNA polymerase and nucleotide substrate, the DNA is amplified to a sufficient amount for structural and functional analysis.

Pcr nasal swab test can be said to be very sensitive.

Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate it until COVID-19 (if present) is detected.

The following may affect the accuracy of PCR nasal swab sampling.

1. Smoking, drinking or chewing gum 30 minutes before use may also interfere with the test results.

2. Touching the swab with the hand or other objects and using the tip of the cotton swab will affect the accuracy of the detection.

Of course, the professionalism of the most important sampling personnel, we have to choose a professional testing agency for testing. And professional VTM Kits.

What should I do if the new coronary pneumonia nasal swab test is positive?

Very bad news!

If the COVID-19 nucleic acid test is positive, a single room isolation treatment should be carried out immediately.

Consultation by in-hospital experts or attending physicians will conduct multiple tests.

Under the premise of ensuring safety, the patient is safely transferred to a designated hospital for diagnosis and treatment.

Don’t worry. You need to actively cooperate with treatment

Otherwise, life is likely to be in danger, and large-scale infections will also occur.

In addition, proper physical exercise should be carried out in life to enhance the individual’s immunity. Colds and fatigue should be avoided.

Don’t do strenuous exercise, so as not to aggravate the disease.

A friend around me was infected with COVID-19. But my nasopharyngeal swab was negative. Is there any way to confirm that I have had it or am I immune to it now?

Certainly.

Antibody test, also called serological test, can detect the antiviral protein IgM and IgG antibodies produced by your immune system in the blood.

What are the types of samples for serum antibody testing?

It is generally blood, including serum, plasma, and whole blood.

How to Choose a Correct Virus transport medium for COVID-19 Testing

Posted on 2021年11月25日2022年3月22日 by Dr. Lee

How to Choose a Correct Virus transport medium for COVID-19 Testing

Disposable virus sampling tube

At present, the form of New Coronavirus is still very serious.

As the first step of covid-19 detection, the importance of sample collection and preservation is beyond doubt.

The influencing factor is sample collection; If there is a problem with the collected sample, the result is invalid regardless of the subsequent treatment.

Selecting appropriate virus transport media and collecting flocking swabs can improve the efficiency of new crown detection.

Almost all virus preservation solutions on the market contain non inactivated viruses directly, resulting in high infection risk for sampling, transportation and testing personnel.

Therefore, the front line of epidemic prevention needs to be able to inactivate virus samples directly.

At 37 ° C, we compared the preservation effects of cell medical (Dongguan) preservation solution containing guanidine hydrochloride and guanidine isothiocyanate with that without guanidine salt on avian coronavirus.

After 1-7 days of storage, under the same condition of 37 ℃, the preservation rate of virus nucleic acid was basically maintained at 100% when it was preserved with cell medical (Dongguan) preservation solution;

·Use virus preservation solution that can protect the sample from high temperature inactivation.

The results showed that high temperature inactivation had no significant effect on the integrity of coronavirus nucleic acid when coronavirus nucleic acid samples were preserved with high temperature inactivator.

The virus preservation solution developed by Cell medical (Dongguan) company is divided into inactivated and non inactivated. Different preservation solutions can be selected according to different test requirements and test conditions. If you have any questions or needs, please call us. Choosing cell medical (Dongguan) virus transport media solution in China is your right choice.

Furan compounds (guanidine isothiocyanate or guanidine hydrochloride, etc.) are typical protein denaturants.

They are often used to extract cell lysis in nucleic acid and inactivate virus. However, the furamethoxam component does not have the ability to work at room temperature.

Because the ability to preserve viral nucleic acid is easy to lead to sample degradation, it is not suitable for preserving new coronavirus samples. Therefore, it is strongly recommended that you choose the preservation solution without guanidine salt.

To this end, we call on the majority of medical personnel to select non inactivated virus transport media if they take samples for the purpose of nucleic acid detection and do not need to culture live viruses.

Vtm Swab | Virus Transport Medium with Sampling Swab

Use a virus medium that inactivates the virus.

At present, covid-19 detection is mainly to detect viral RNA, which needs to divide the virus.

Therefore, as long as the integrity and stability of virus nucleic acid can be guaranteed, there is no need to preserve live virus.

Therefore, in the current situation of fighting COVID-19, it is ideal to inactivate the virus while collecting samples. Some manufacturers have also introduced inactivated transport medium, but its inactivating component is guanidine salt.

The results showed that the salt forming component storage solution had insufficient storage capacity for viral nucleic acid at room temperature, which was easy to cause sample degradation.

Therefore, we recommend the use of virus preservation solution containing non guanidine protein denaturants.

The volume of solution in the sampling tube should be appropriate.

① When sampling each sample separately, we recommend that you select a virus sampling tube containing 1ml storage solution to ensure the correct storage capacity. It can not only meet the downstream needs of nucleic acid extraction and detection. Compare with 3ml storage solution. Triple the virus concentration!

② For large-scale preliminary screening and mixing test, we should choose to put the samples of 3-5 people into the sampling tube.

·Use a virus preservation solution that can transport and preserve samples at room temperature.

If the delivery temperature does not meet the standard, the viral nucleic acid may degrade, resulting in a “false negative” test result!

On the contrary, if cell medical uses a virus storage solution that can transport and stably store virus nucleic acid at room temperature.

We solved the problem of sample transportation and improved the accuracy of test results.

·Use virus preservation solution that can protect the sample from high temperature inactivation.

However, the research reports of Beijing Center for Disease Control and prevention in the Journal of “clinical chemistry” and Beijing Preventive Medicine Research Center show that high temperature inactivation can lead to the degradation of virus nucleic acid, thus reducing the detection rate of virus nucleic acid. Therefore, The false negative rate of New Coronavirus nucleic acid detection is high.

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.
