COVID-19 Swab Test: What you should know

COVID-19 Swab Test: What You Should Know

Posted on by

An abrupt COVID-19 has brought flocking swabs, nasopharyngeal swabs, oropharyngeal swabs, nucleic acids, antigens, PCR and also other extremely professional terms right into the public eye. Today, CellMedical will certainly offer you preferred scientific research: those aspects of Coronavirus (COVID-19) screening.

What is a flocking swab, nasopharyngeal swab, or oropharyngeal swab?

When nations are executing a new round of nucleic acid screening, a report is spreading out in circles. The basic concept is “the cotton bud used for sampling have reagents on them, which are hazardous”. Some netizens also left a message to the CellMedical firm backstage, saying that after seeing the pertinent reports, the elderly at home shared that they did not want to take part in nucleic acid testing, and also really hoped that the younger generation would additionally attempt not to undertake nucleic acid testing as well as antigen testing.

“The covid test swab is not the same as the cotton swabs used in daily life, but it does not contain reagents, nor is it toxic”. ( Click here to learn more )

What is a flocked swab and why choose flocked oropharyngeal and nasopharyngeal swabs?

A flocked swab is used because it is more suitable for sampling and testing. The flocking swab(learn more) is made of nylon fiber flocking technology, and the front end is coated with nylon short fibers fixed in a vertical manner, so that there is no absorption hole in the entire collection area of ​​the collection swab. In this way, the collected sample is not dispersed and retained in the fiber, which facilitates faster and more efficient elution. Relevant data show that CellMedical flocked swabs can elute more than 95% of the sample collection volume; traditional cotton swabs, especially those made of absorbent cotton, cannot completely collect and elute samples.

Enlarged view of flocked swab

Enlarged view of flocked swab

Nasopharyngeal swabs – which require a swab inserted into the nose to collect samples from the back of the nose and throat – are the gold standard for collecting samples for diagnosis. But the process is technically difficult, often uncomfortable for patients, and requires personal protective equipment that may be in short supply.

Oropharyngeal swab – the oropharyngeal swab is a method of collecting oropharyngeal specimens by entering the sampling swab through the mouth – compared with a nasopharyngeal swab, it is less difficult, more acceptable to the public, and more universal. 

What exactly is PCR nucleic acid detection?

PCR (Polymerase Domino Effect, polymerase chain reaction) innovation is a wonderful creation, without the creation of PCR modern technology, there would be no modern-day molecular biology. Nucleic acid detection modern technology has likewise entirely transformed several techniques such as genetics, medication, and also forensics, allowing human beings to accomplish significant steps such as hereditary testing, viral infection identification, and also genetic testing.

"<yoastmark

Basically, PCR nucleic acid detection: To significantly magnify nucleic acid till it can be identified by equipment detection.  Yet if you increase the size of the nucleic acid, 1 ends up being 2, 2 comes to be 4, and also 4 ends up being 8. Consequently, PCR innovation is a method of amplifying nucleic acid.

After the covid-19 contaminates the human body, it will initially increase in the respiratory system. So it can be determined whether the body is infected by finding the viral nucleic acid in sputum and nasopharyngeal swabs. After a duration of infection, typically 7-10 days later, the body will certainly create specific antibodies versus the virus. IgM antibodies show up initially, adhered to by IgG antibodies. So immunological discovery approaches can identify these specific antibodies to identify whether the human body is carrying the virus.

Will the results from different nucleic acid testing institutions be consistent?

PCR nucleic acid detection has a strict standard procedure. It is the same SOP (Standard Operation Procedure). At the exact same time, all nucleic acid labs, regardless of dimension, must adhere to the same technological demands, and also the design and building of laboratories additionally have uniform specifications. Also, research laboratory screening staff have to go through standard technical training and also acquire a nationally identified task certification before they can work. It resembles KFC’s fried chicken all use the exact same dish. Whether it’s a fast window in the station, a sizable and comfortable dine-in in the town hall, or home delivery, you can constantly eat deep-fried chicken with the exact same preference, do not fret will certainly strike rumbling.

Therefore, no matter which institution we conduct nucleic acid testing, the outcomes need to coincide.

The collection of samplings from different components has different clinical importance. Along with the popular nasal swabs and throat swabs, sputum, blood as well as rectal swabs；

Nasal and throat swabs – upper respiratory tract specimens

Sputum – Lower Respiratory Tract Specimens ( Saliva Collection Kits )

Anal swab – digestive tract specimen

Blood – Antibody Test Specimen

What is the difference between nucleic acid testing and antibody testing?

The distinction between both is a positive nucleic acid shows the presence of viral nucleic acid in the sampling. Which suggests that the infected individual might be infectious. A favourable IgM antibody shows that the patient remains at the beginning of infection. IgG antibodies indicated that the patient had SARS-CoV-2. However, we were unable to determine whether it was transmissible. Compared with antibody detection, PCR nucleic acid discovery is much more sensitive and is additionally the “gold criterion” for laboratory detection.

Therefore, in recent cases, doctors discussed that the patient has symptoms of infection.

What factors may affect COVID-19 nucleic acid test results?

1. Viral load: In summary, when the viral lots are low. False negatives may occur.

2. The coronavirus may alter, which may further impact the accuracy of the test in the future.

3. Testing method: In the recently reported genuine tasting scene, several participants reported that the swab only revolved left and right in the mouth, and it really felt like it was only touching saliva.

However, did not reach the lingual and palatal arc, and the respondents did not have nausea and also reflexes. Sex-related security action, this type of tasting has a high possibility of not gathering exfoliated cells of the respiratory tract, so it is vulnerable to missed discovery, leading to false unfavourable results.

What is the difference between a nasal (Nose) swab and a throat swab for nucleic acid testing

The sampling method and location are different. The accuracy rates of the nucleic acid test ( PCR Test ) nasal swabs and throat swabs are usually similar, and the main difference lies in the sampling method and sampling site. For nasal swabs, nasopharyngeal swabs (flocking swabs) are mainly used to test the secretions from the inside of the nasal cavity and the surface of the nasal mucosa through the nasal cavity;

Throat swabs: Health care workers collect samples in the mouth with oropharyngeal swabs. Health care workers take throat samples for testing to determine whether a patient has the new coronavirus.

Are both throat swabs and nasal(Nose) swabs required?

Let’s talk about throat swabs first.
The “oral sampling” and “nasal sampling” mentioned above are actually test methods in which medical staff use medical swabs to collect samples from the pharynx in nucleic acid testing (PCR).

COVID-19: Will The Pandemic End in 2022?

It is very important to continue swab testing while the pandemic is still ongoing

Whether entering from the nasal cavity or the mouth, the specimens we need to collect are pharyngeal secretions, including sputum. Compared with the oral route, nasal sampling can provide better safety protection for the sampling person. Because oral sampling requires subjects to open their mouths wide, this increases the risk of virus transmission by droplets. However, if it is collected through the nasal cavity, the environment is relatively stable, and the medical staff who operate it will be safer.

What is the difference between a throat swab and a nasopharyngeal swab, which is more accurate?

The main difference between nasal swabs and throat swabs lies in the location and material of the specimens, which are usually as accurate. The throat swab is in the pharynx, and the nasal swab needs to go into the nasal cavity, not the external nasal cavity. It needs to use a longer swab and slowly rotate it to the deep part of the nasal cavity, so the parts of the material are different. Nasal swabs are special, and the material is relatively soft, which is convenient for reaching the deep nasal cavity through the nasal cavity. The process of taking it may take longer than that of throat swabs.

Compared with nasopharyngeal swabs, oropharyngeal swab sampling is sometimes difficult to meet the normative sampling requirements due to irritating reactions, and the actions of eating, drinking and swallowing will reduce the oropharyngeal to a certain extent. The virus enrichment of 2000 may affect the positive detection rate of oropharyngeal swabs.

Which is better, nasal(Nose) swab or throat swab?

No matter which one is adopted, the key lies in the depth of the collection, whether the collection is in place and the length of contact time with the deep mucosa. 

 From the personal experience of the testing population, throat swabs will be less irritating and uncomfortable than nasal swabs.

Flocked Sterile Swabs

Sterile Flocked Swab

Oropharyngeal swab

　　• The operation is relatively simple and less irritating, suitable for large-scale screening.

　　• The sampling staff will guide the subject to open the mouth, and then use a sterile long cotton swab to gently scrape the subject’s throat to collect secretions from both palatine arches, pharynx, and tonsils.

Nasopharyngeal swab

　　• The technical requirements are high, the human body does not feel very comfortable, and the accuracy is higher than that of oropharyngeal swabs. For key groups such as isolation points.

　　• The sampling staff will insert a long sterile cotton swab into the nostril of the subject, and reach the mucous membrane deep in the nasopharyngeal cavity, stay for a few seconds to soak the secretion, and then take it out.

Who is not suitable for nasal swab

What is A Covid-19 NP Swab?

What is A Covid-19 NP Swab?

When collecting nasal swab specimens, the flocked swab ( learn more ) will enter the nasal cavity.  

f the medical staff operates in a standardized manner, it will reduce the irritation to the mucous membranes.

But because we can’t see the sampling position of the pharynx.

It mainly relies on the hands of medical staff to feel the resistance, so the technical requirements of the operator are very high, and the tools used are also more complicated.
The improper operation will cause certain irritation to the nasal mucosa, so it is not recommended for patients with sinusitis and allergic rhinitis to do nasal swabs to avoid damage to the nasal cavity.

How to overcome the discomfort of throat swab

When collecting throat swab specimens, the oropharyngeal flocked swab will cause certain irritation to the pharynx. For some people with the sensitive pharynx, nausea and vomiting may occur.

Recommended to relax before collecting specimens.

Don’t get too nervous. If you feel discomfort in your throat after collection, you need to eat less spicy, irritating and greasy food, drink more water, eat more vegetables and fruits, and arrange rest appropriately. Generally speaking, it does not take long to return to normal.

Experts said that the study found that the nucleic acid-positive duration of feces or anal swabs of some infected people is longer than that of the upper respiratory tract. Increasing anal swab sampling can improve the detection rate and reduce missed diagnosis; but anal swab sampling is not convenient enough, and currently only for isolation. Points and other key groups to use.

After the test is completed, the sterile flocked swab will be processed for medical waste. However, news broke out recently that refreshed the three views, and netizens called out “there is no bottom line”!

According to reports, employees of a medical company in Indonesia were found to be repeatedly using sterile nasal swabs when testing airport passengers. At present, more than 9,000 passengers are expected to be affected.

After investigation, the Indonesian police found that the employees involved first performed Nasopharyngeal Swabs tests on passengers with sterile nasal swabs every day, then cleaned the used sterile swabs with alcohol, and then packaged them for use by the next batch of passengers. . This behaviour is outrageous.

What are the dangers of reusing nasopharyngeal swabs?

The nose is a barometer of human health. When there are lesions in the body, the colour of the snot changes to yellow or green. Nasopharyngeal swabs are a test sampling method to assess the presence of respiratory viral or bacterial infections by collecting samples from the surface of the respiratory mucosa.

As a rule, nasal swabs cannot be reused. If the nasal swab is reused, the consequences will be disastrous.

If the nasal swab is reused, it will increase the risk of virus infection. Previously, a British research team found that two kinds of cells in the nose may be the other infection sites of the new coronavirus. A clinical study found that the viral load of nasal flocked swabs The amount is significantly higher than that of throat swabs. If nasal swabs are reused, it is likely to cause cross-infection and expand the scope of infection.

On the other hand, it may lead to inaccurate test results, false positives or false negatives. It may cause psychological panic and unnecessary treatment to the subjects, and false negatives may mean that the subjects cannot find out that they have been infected in time, miss the best treatment time, and even cause more people to be infected.

Why are the sample collection swabs for nucleic acid testing all put together?

This kind of multi-person mixed inspection can improve efficiency and reduce costs.

"<yoastmark

Mixed sampling testing refers to mixing samples from multiple people (generally no more than 10 people) into the same test tube for testing, improving testing efficiency and reducing testing costs, but the waiting time for centralized sampling may be slightly longer. According to the voluntary principle, the nucleic acid test of all employees can be tested by mixed sampling technology. The laboratory testing time for mixed sample and single-tube testing is the same, which does not affect the time for issuing the testing report.

The so-called five-in-one and ten-in-one mixed sampling detection technology are to put 5 or 10 individual swabs into a collection tube. When the test result is negative, the mixed sample is negative, and the mixed sample is 5 people. or 10 people are safe;

If there is a positive result, the relevant department will be immediately notified to temporarily isolate the 5 or 10 subjects in the mixed tube, take a single tube swab again for the review, and then determine which of the 5 or 10 people is positive.

What should I pay attention to when doing a nucleic acid test (PCR test)?

Today,  many people who travel to and from high-risk areas of the epidemic require nucleic acid testing.

So, what should we pay attention to when doing nucleic acid testing (PCR SWAB TEST)?

Before the nucleic acid test: do not eat within 2 hours, do not smoke or drink within 30 minutes, carry a valid ID card, wear a mask correctly, and inform the testing personnel of past medical history or related matters.

When doing nucleic acid testing: Keep a distance of more than 1 meter when queuing, tilt your head slightly, relax, take a deep breath, and have symptoms such as dry cough or sneezing, use a tissue or cover with your arm.

After the nucleic acid test: leave the collection site immediately, and wipe your hands with hand sanitiser or alcohol.

In fact, whether it is a nasopharyngeal swab or a throat swab, it is an effective virus detection method. Although there will be slight discomfort during the test, it will soon return to normal and will not affect your health. Therefore, if necessary, we must actively cooperate with nucleic acid testing, which is responsible for ourselves and others.

Nucleic acid detection: For virus detection method.

It uses a collection flocked swab to collect a sample from the throat or nose of the tester and then conducts the test to obtain the final result.

Some people found that the flocked swabs for nucleic acid testing will be placed in a bottle(VTM Tube).

This is a mixed test, and most of them occur during nucleic acid testing of all staff, which will not affect the detection effect.

Will the swabs for nucleic acid testing be reused?

Prohibition reused.

In addition to sampling, reagents and other factors, the subject’s own reasons may also lead to “false negatives”.

Not to eat for two hours before the nucleic acid test, not to drink water for the first 30 minutes. And not to smoke, drink water or chew gum to reduce behaviours that may interfere with the test results.

There are other influencing factors before sampling and testing,

1. Please do not take antibiotics a few days before the nasal swab.

2. Do not use disinfectant mouthwash or smear on the affected area a few hours before the nasal swab.

3. Do not eat, smoke, or drink for a few hours before the nasal swab.

Only one month after the US lifted the mask order, Philadelphia will usher in a mandatory mask order again.

Beginning April 18, local time, more than 1.6 million Philadelphia residents must wear masks again when entering indoor public places. Philadelphia became the first major U.S. city to impose a mask mandate as cases rose again.

On April 13, the World Health Organization (WHO) New Crown Pandemic Emergency Committee held a meeting. After discussion, it was determined that the new crown pandemic continued to constitute a “public health emergency of international concern”, and countries were advised to prepare for it at any time. Do a good job in vaccination and PCR swab testing.

WHO Director-General Tedros Adhanom Ghebreyesus said: “It’s far from the time to let our guard down.”

According to the latest data from Johns Hopkins University in the United States. The number of confirmed cases of new coronary pneumonia in the world has exceeded 500 million. And the number of deaths has exceeded 6.1 million.

Endorsed by the WHO, in other words, one in 16 people in the world will carry the covid virus.

Since December last year, Omicron has been rampant around the world, with more than 200 million new confirmed cases worldwide in 2022.

500 million, or 5 billion?

At the same time, many experts and even the WHO believe that the number of truly infected people in the world is far more than 500 million, and may even exceed 5 billion.

Not to mention India, Africa and other countries and regions with poor medical conditions, weak testing capabilities, and chaotic management, even in the United States, the CDC has previously acknowledged that the number of infections reported nationwide is estimated to be less than 1/4 of the actual number of infections.

So, can the covid-19 stop this year?

COVID-19: Will The Pandemic End in 2022?

Faced with this question, WHO spokesman Tarik Jasarevic did not respond positively, but reiterated that in order to end the acute phase of the new crown pandemic, scientists have developed an effective epidemic prevention and control response.

He also warned: “As the new crown epidemic continues to spread on a large scale around the world, the emergence of more new crown variants and recombinant variants is foreseeable.”

Tedros said that the WHO is currently closely monitoring the development of BA.2, BA.4, BA.5 and other Omicron subtype strains, as well as the recombinant XE formed by the combination of BA.1 and BA.2 evolution.

BA series and X series, how dangerous?

Although the number of new cases around the world has been declining for three consecutive weeks. There are also some countries and regions where new cases are still climbing.

Many Asian countries are experiencing the Omicron wave for the first time. In South Korea, new infections and deaths have continued to climb since February.  The country now has the world’s highest daily average of new confirmed cases for a week. According to a Reuters analysis, South Korea currently has an average of more than 182,000 new confirmed cases per day, accounting for a quarter of the world’s newly confirmed cases.

Some European and American countries have experienced a wave of Omicron infection peaks at the beginning of this year, but the epidemic has recently rebounded.

In Europe, the daily increase of confirmed cases in France has shown a slow upward trend, and the seven-day average of newly confirmed cases in Germany has declined, but it is still at a high level. Reuters pointed out that the number of new cases in Europe is still huge, with more than 1 million new confirmed cases almost every two days.

At present, BA.2 is the main circulating strain in many countries, accounting for 94% of all gene sequencing.

While BA.4 and BA.5: Found in South Africa and many European countries.

Experts believe that if more people can be vaccinated and more people have the tools to fight the epidemic, then we can reduce severe cases and further reduce infections, thereby gradually ending the pandemic.

He also emphasized that it is very important to continue swab testing while the pandemic is still ongoing so that cases can be accurately tracked.

Flocked Swab

Flocked Swab

Nylon flocked swab

Made of nylon fibre flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner.

Increasing the efficiency of collection and release of cellular and fluid samples.

So that there is no absorption hole in the entire collection area of ​​the swab.

The collected sample does not disperse and remains in the fibre, facilitating faster and more efficient elution.

Traditional spun cotton swabs cannot completely collect and elute the sample, while flocked swabs can elute more than 95 per cent of the sample collected.

So the use of flocked swabs has great advantages for a variety of sample collection applications.

Because most of the testing tools used for nucleic acid testing are disposable sampling swabs, we usually see more nasal swabs and throat swabs.

Improve analytical sensitivity, no sample residue, and speed up sample processing.

PS stickers come off easily. Suitable for cervical, nasopharyngeal, oral, forensic collection systems and DNA collection, etc. Individually packaged.

Flocked swabs are biocompatible and ideal for PCR work.

PCR is compatible, free of RNase and DNase, so the new flocked swabs are ideal and a good choice for scientists working with PCR technology.

Flocked swab sampling is more comfortable and easier to use;

CellMedical’s flocked swabs use the existing technology “spraying technology”, which is to vertically attach millions of nylon fibres to the head of the medical swab shaft through electrostatic charges in the flocking hair.

The vertical nylon fibres resemble a soft brush.

During sampling, the user will have no foreign body sensation.

In addition, different parts have different breaking points of the flocking swabs used, and the thickness of the swab rod is also different.

So there is a big difference in softness.

For example, for nasal swabs, the upper end of the swab rod is thin and soft, and the breaking point is also relatively back.
