Pooled Sample Test?

With the 2019 coronavirus disease (COVID-19) pandemic, doing a good job in viral nucleic acid detection is the top priority. However, detection of the virus is still limited due to resource constraints. Pooled sample testing offers a way to significantly improve testing power.

“mixed nucleic acid test” or “Pooled Sample Test”, referred to as “mixed test”.

Which means that two or more samples are mixed and tested. method for positive samples.

What is the difference between the “mixed collection” of community nucleic acid testing and the “single collection” of the hospital?

Why do community streets adopt the mixed mining model?

Under what circumstances should I test individually?

What is pooled COVID testing?

The so-called “mixed detection” of nucleic acid.

Takes throat swab samples from multiple people and puts them together for viral nucleic acid detection.

Pooled Sample Test VTM Kits

In fact, Medical use of Pooled Samples is common.

In blood collection systems such as apheresis stations.

We use pooled samples to detect the presence of infectious disease antigens and antibodies in pooled samples of multiple people.

There are two modes of “mixed detection”. One is to sample several people, such as 3 or 5 people and put them into the same sampling tube.

The other is to mix samples of the same volume from 3 or 5 people during laboratory testing, also known as “sample mixing”.

From a scientific point of view, the first “mixed sampling” mode will not affect the sensitivity of nucleic acid detection. While the latter mode of mixed detection of samples has a certain impact on the sensitivity of the detection, the degree of impact is controllable.

In order to detect high-risk groups, such as symptomatic patients and close contacts in fever clinics, we still recommend separate sampling.

For screening of low-risk groups, pooled sample test is our first choice.

Is the mixed detection technology reliable?

Is the “five-in-one” and “ten-in-one” mixed mining detection technology reliable?

“The size of the single-collection tube and the mixed-collection tube are different, and the amount of the preservation solution is also different.

Based on the results of a large number of basic experimental research and practical operations in the previous period.

The increase in the volume of the mixed-collection preservation solution has no effect on the detection results of weakly positive specimens.”

In the case of an extremely low positive rate, the 10-in-1 mixed detection technology is very efficient.

The FDA is aware that there is a great interest in performing testing using pooled samples.

This approach increases the number of individuals who can be tested with the same amount of resources.

What are the benefits of mixed nucleic acid detection?

The hybrid detection of nucleic acid has greatly improved the nucleic acid detection capability, reduced the burden of personal testing costs, and did not affect the time for issuing the test report.

The testing time of a single test and mixed test laboratory is the same, but compared with a single test, the mixed test is more suitable for mass and group screening.

In the case of small-scale outbreaks, the use of mixed detection can improve efficiency, play the role of multiple screening, early diagnosis, reduce transmission, and save social costs.

Whether the population is suitable for mixed testing shall be carried out in accordance with the requirements of the provincial and municipal epidemic prevention and control headquarters,

The medical institutions carrying out the testing must follow the technical requirements and standards of the municipal health department.

Which groups recommend the single purchase and single inspection?

It is worth mentioning that single sampling and single inspection are recommended for specific populations.

The above notice specifically mentioned that COVID-19 nucleic acid 10 in 1 and 5 in one mixed detection technology is suitable for large-scale rapid screening of the low-risk populations, and is more suitable when the overall positive rate of population is low (0.1%).

However, for the detection of high-risk groups such as symptomatic patients, close contacts and people in key areas in fever clinics.

Recommended to adopt single sampling and single detection.

What should I pay attention to when doing pooled sample detection?

1. When going to the testing point for nucleic acid testing, wear a mask, and it is best to prepare one or two spare masks.

2. Two hours before the swab test, it is recommended not to eat to avoid vomiting during the test.

3. When waiting for the test, remember to keep a distance of more than one meter between the front and rear personnel to avoid close contact.

4. Whether it is doing swab testing or getting the report, it needs to be certified as one, so be sure to bring ID cards, receipts and other materials, so as to avoid incomplete materials at that time, which will affect the testing and reporting.

How accurate are saliva swab DNA tests?

Posted on 2022年1月4日2022年1月4日 by Dr. Lee

Is the DNA test of the saliva swab accurate?

Many people doubt the accuracy of the saliva swab test.

However, you can rest assured, because the accuracy of oral saliva swab testing is as accurate as other DNA testing methods.

Moreover, this is not the same as a finger puncture or a blood test, it is not painful at all.

In recent years, DNA testing has become more and more popular.

Whether you want to confirm your parental relationship, understand where your genes come from or want to optimize your exercise.

We are currently working on direct-to-consumer DNA testing of saliva swabs.

You have decided to use DNA testing to better understand your body and optimize your training.

However, before you take the first step and buy a set of home DNA testing kits, you should have some concerns.

Although most of the feedback and research has been confirmed to be positive, we are here to learn more about this and help you make an informed decision.

How much saliva is needed for a DNA test?

Saliva Sample Collection Kit: Disposable saliva DNA RNA sampling tube

2ml-4ml.

The saliva collection components are easy to use, and each set has detailed instructions.

You can provide samples for different health conditions, including common medications used during pregnancy, colds or flu (including medications for acid reflux or heartburn).

But if you want to use drugs to reduce the white blood cell count, such as chemotherapy, you’d better wait two weeks or wait until the white blood cell count returns to normal.

After mixing with DNA stabilizing buffer, the temperature range of your saliva sample (-4oF to 122oF) is stable.

Please send the collected samples to the laboratory as soon as possible.

Is the DNA test at home accurate?

Yes, DNA testing at home is very accurate.

You will only encounter errors when the genetic sample is damaged (for example, you have eaten before the sample is collected) or the laboratory quality is poor.

Therefore, it is necessary to choose a well-known DNA testing supplier for testing.

An accurate genetic test report can know in advance whether the body is in danger of disease.

By improving the living environment and behaviour habits, avoiding or delaying the occurrence of the disease, or determining whether there is a specific drug in the case of malignant disease.

Target, so as to more accurately select the treatment method.

The results in each report are derived from at least three peer-reviewed research papers.

It just repeats the genes that have an impact on health, health and nutrition.

This means that you can change the way of real-life based on the genetic variants you carry.

Through strict internal and external procedures, we have passed ISO27001 certification to identify risks, evaluate all control systems, improve our reliability and security, and comply with international data security standards, so as to ensure that our customers and business partners can trust us.

What can you do to ensure that your DNA test results are accurate?

In order to ensure that your DNA test results are accurate, you need to follow the instructions at the back of the box.

Before starting, please read the instructions carefully:

Before wiping dry, make sure you have nothing to eat or drink.

-The best time to take the exam is to brush your teeth in the morning and the first thing before drinking the first cup of tea.
Before taking the test, it is best to open the sealed mouth swab to ensure that it will not be affected.

After removing the cotton swab, open your mouth and use a pointed tip (cotton swab, slightly larger) to gently wipe your cheeks.

Try not to scrub vigorously, because the important part of the sample is saliva.

Be sure not to put paper towels in the plastic container provided.

Take care to break the pole where it is needed.

Fill out the attachments, sign and seal the enclosed envelope, and then send it to the laboratory for inspection.

Bear with patience and watch your test. This process will start with the receipt of samples in the laboratory and will take 10-14 days.

Is the accuracy of mouth swab detection relative to other DNA collection methods?

Because the saliva swab is noninvasive, many people question its accuracy.

However, you can rest assured that the accuracy of oral swab detection is as accurate as other DNA detection methods. And, unlike finger punctures or blood tests, it doesn’t hurt at all.

Whether you are building a cabinet in IKEA, pressing a map or doing DNA testing, you can get accurate results as long as you follow the instructions.

Remember, DNA testing is wrong only if your test results are wrong or you don’t follow the instructions.

Cost is an important factor in performing such tests, so it must be studied.

Often, you don’t just pay for the test suite. You also have to pay a test fee to analyze your results. If the test you selected does not belong to the laboratory, please choose a supplier with a good reputation and excellent laboratory.

Every laboratory we use will conduct regular spot checks to ensure that your samples have been tested correctly and your results are 100%.

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

Nasal Swab VS Oral Swab

Some customers inquire:

Are nucleic acid tests all about poking the throat?

Will you poke your nose?

“Poke the nose” through the Internet is more accurate,

is that true?

Don’t panic, let’s learn about it with Xiao Liu from Cell medical!

When doing nucleic acid testing,
There is a very important project,
Just do a throat swab
There are two types of throat swabs-nasopharyngeal swab and oropharyngeal swab sampling.

Currently
Most hospitals use
Oropharyngeal flocked swab
Because-it is the most convenient to collect samples and less painful.

But there are rumors,
The detection rate of nasopharyngeal swabs is higher,
is that true?
Yes! Yes! Yes!
Studies have shown that the poison load of nasopharyngeal swabs in patients infected with the new coronavirus is much greater than that of oropharyngeal swabs.

Focus on:
Wear a mask when you go out!
Wear a mask when you go out!
Wear a mask when you go out!

The important thing is said three times!

Nucleic acid detection, antibody detection

confuse?

After the new coronavirus infects the human body, it will first reproduce in the respiratory system. Therefore, it can be determined whether the human body is infected with the virus by detecting the viral nucleic acid in the sputum and nasopharyngeal swabs.
To
After a period of infection, usually 7-10 days, the human body will produce specific antibodies against the virus. IgM antibodies will appear first, and then IgG antibodies will appear. Therefore, detecting these specific antibodies can determine whether the human body has been infected with the virus. ,

If allowed,

You can, according to your own tolerance,

Choose whether to do a nasopharyngeal swab or an oropharyngeal swab.

in addition,

The serum antibody test is to draw venous blood,

No need to fast!

Flocked Swabs for Sample Collection

Posted on 2021年11月20日2022年3月22日 by Dr. Lee

Flocked swabs for sample collection

The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod.

The brush head can be used for Virus cell collection.

It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

flocked swabs for sample collection

Why flocked swabs?

The flocking swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod. The brush head can be used for DNA collection. It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

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

And the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.

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

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

Nasopharyngeal flocked swab;

Flocked swabs have some advantages;

1. Sampling is comfortable and easy to use;

Flocking swabs now basically use “spray technology”, which vertically attaches millions of nylon fibers to the head of medical ABS swab rod through the flocking process of electrostatic charge.

The function of the vertical nylon fiber is similar to that of a soft brush. The use of this soft brush in the sampling process makes the user feel free of foreign objects. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

For example, the nose swab is thinner and softer at the upper end of the rod, and the breaking point is longer, which fully conforms to ergonomics.

2. Flocked swab samples release more;

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is kept on the surface to make elution easier. It is much larger than the traditional winding cotton swab. The experimental research shows that the collection and release of flocking swab can reach 95% of the sample, while the cotton swab is only about 20%.

Because most of the samples collected by the cotton swab are easy to be intercepted in the fiber matrix layer of the head during release, it is not easy to release or release a small amount.

3. Flocking swab has biocompatibility and is an ideal choice for PCR;

In order to limit the damage to the sample and improve the accuracy of detection, while the flocking swab is PCR compatible and does not contain RNase and DNase.

Operation method of flocked nylon swab:

Take the sampling method of oropharyngeal swab as an example;

1. First, ask the patient to sit down, then let the patient tilt his head back, open his mouth, and make an “ah ~” sound.

2. The sampler fixed the patient’s tongue with a tongue depressor, and used a flocking swab to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.

3. Wipe repeatedly for 3 ~ 5 times to collect mucosal cells.

4. Slowly take the swab out of the mouth, vertically put it into the virus preservation solution, break the tail of the swab, and tighten the sampling tube to avoid leakage.

5. Send to the laboratory for testing as soon as possible.

Swab flocked matters needing attention:

1. The swab shall be placed vertically in the sampling tube, and shall not be wiped to the bottle mouth to avoid pollution.Viral Transport Medium.flocked swab copan.

2. It is best to send it or send it to the laboratory for inspection on the day of sampling.

3. Before submission for examination, it must be verified that the specimen is consistent with the submission form. The appearance of the sampling tube must clearly write the patient’s name and basic information.

4. The submitted samples must submit (or submit the electronic version in advance) screening information form, inspection form and other materials.

What are the advantages of flocking as a sampling swab?

advantages of flocking as a sampling swab

When it comes to sexual sampling swabs, I believe you don’t feel strange at this time.

Because most of the detection tools used for nucleic acid detection are disposable sampling swabs.

Sampling swabs directly contact our human organs, such as nasal swabs and pharyngeal swabs for nucleic acid detection.

So the material selection of sampling head is very important, and the material of sampling head is closely related to subsequent detection. The sampling swab shall ensure the sampling amount and release amount, and the selected material shall not have substances that affect the subsequent detection.

Advantages of flocked swab

Flocked Tip Swab,Cell medical (Dongguan) Co. ,Ltd.

·Compared with the traditional winding swab, the amount of samples collected and released by flocked swab is three times higher, and it will not cause harm to human body.

·The sampling time of flocking swab is 3-5 seconds, which is fast and convenient to improve work efficiency.

Only by extracting samples faster can we complete the collection and analysis more efficiently.

·Moreover, through the directional friction effect of the brush fiber layer,effective collection of samples.

Therefore, the flocking swab is particularly conducive to the collection of trace DNA.

·A large number of clinical experiments show that compared with ordinary sterile cotton swabs, flocking swabs have a better effect on the collection and transportation of clinical microbial samples. This is especially true for those specimens that cannot be submitted for examination in time and placed for too long.

Nasal Swabs for Sample Collection

Posted on 2021年10月26日2022年3月22日 by Dr. Lee

Nasal Swabs for Sample Collection

I believe many people are very curious.

There is already a throat swab.

Why do you have to do a Nasal swab?

In the actual anti epidemic work scene, in fact, medical staff have a set of scientific judgment basis for collecting oropharyngeal swabs or nasopharyngeal swabs.

Because the nose swab only needs to expose the nose during the sampling process, the probability of exposure to the virus environment is low.

For high-risk people, such as asymptomatic infected persons, entry personnel or suspected people being isolated.

Nucleic acid detection with nasal swabs can reduce the infection risk of collectors, and the psychological acceptance of samplers.

That is, medical personnel, is also higher.

For the nucleic acid detection and screening carried out in the community, due to the more emphasis on rapid screening, the use of oropharyngeal swabs is more convenient and fast.

If discomfort or slight bleeding occurs during the collection of nasopharyngeal swabs, it is generally not treated.

After a period of time, the discomfort will disappear automatically.

If it is really uncomfortable, it can be properly cleaned with normal saline.

But do not wash too much, too much cleaning may bring more pollution.

Why is flocking swab used in nasal swab PCR test？

In order to improve the swab collection efficiency and meet the needs of end consumers for high-quality products.

Cell medical’s Flocked swab came into being.

Innovative jet implanted nylon fiber technology to maximize the sampling efficiency of the sampling swab.

The nylon fiber is vertically and evenly attached to the surface of the swab head, greatly increasing the collection and release efficiency of cell and virus samples.

Improve the analysis sensitivity, no sample residue, speed up the sample processing process, and the unique breakable design of ABS plastic rod.

It is applicable to the collection of cervical, nasopharynx, oral throat, forensic samples, virus, DNA and other samples.

◆ upright nylon fiber is like a soft brush, which can collect more specimens.

The capillary action between nylon fibers enhances the load of aqueous samples, and the samples are concentrated on the surface of the swab, which is easier to elute.

◆ it has outstanding sample collection and release ability, can quickly adsorb micro samples, and has high release aging rate. The increase of the number of target cells is helpful to improve the sensitivity of rapid diagnostic test.

◆ flocked swab has obvious advantages in nasopharyngeal sampling and microbial sampling, especially in the collection effect of virus and DNA.

◆ 100000 class purified environment, strict production process conditions, and production under ISO13485 quality control and product CE requirements. No DNase and RNase, no endotoxin, no cell inhibitor.
