Nasopharyngeal Swab Collection Instructions

Nasopharyngeal swab sampling： A thin flocked swab into the nostril, from the lower nasal meatus to the posterior wall of the nasopharynx.

And then twisting the swab for sampling.

The depth of the sampling swab into the nasal cavity is approximately the distance from the tip of the nose to the earlobe.

How to collect a Nasopharyngeal (NP) swab

1. Keep your head still, to remove the secretion on the surface of the anterior nostril;

2. Measure the distance from the tip of the nose to the earlobe with a swab as well as mark it with your finger. Put the swab right into the nasal dental caries in the direction perpendicular to the nose (face), and also reach the posterior nasopharynx when it comes across resistance, to make sure that the swab stays in the nose for 10-15 s, gently rotate 3 to 5 times to secure the examination piece.

There is definitely no demand for the sampler to stand straight opposite the patient. The advantage of standing on the side is that if the patient has coughing, sneeze, etc, it can be avoided in time.

It is vertical to the coronal airplane of the head or the face and also permeates deeply from the inferior meatus to the posterior wall of the nasopharynx, as well as it is enough to feel the wall surface. The depth of the nasopharyngeal swab right into the nasal tooth cavity is about the range from the pointer of the nose to the earlobe (see picture).

Nasopharyngeal sampling

Nasopharyngeal sampling

3. The nasopharyngeal swab must be turned on the nasopharyngeal mucosa, maintained for 10-15 secs, and after that got rid of. The kid’s participation is poor. In practice, we typically obtain the swab in three to five secs after completely twisting it 2-3 times.

Nasopharyngeal swab vs nasal swab

A nasal swab (often called an anterior nose test): A sample taken by touching both sides of the nasal wall. The nasopharyngeal swab is to probe from the nose to the throat.

What is the nasal swab technique?

The nasal swab approach uses a swab to accumulate an analysis example from the nasal membrane. The nasal swab examination (frequently described as the former nasal test) involves putting the swab around 0.5-0.75 inches deep into the nostril as well as turning it in one nostril for 10-15 seconds while touching both sides of the nasal wall, then making use of the same cotton swab, Gather in the other nostril similarly. Since this approach is less invasive, it is usually extra comfortable for the patient – and is additionally the approach utilized when self-testing.

nose structure

Nose structure

Nasopharyngeal swab

Impacted by elements such as age and also face structure development, there are private differences in the collection deepness of nasopharyngeal swabs.

We should pay attention to personal protection when collecting nasopharyngeal swabs, and clean the nasal cavity before collection.

If the patient has nasal septum curvature, the background of nasal surgery, rare coagulation characteristics, etc., the patient should inform the collection staff in advance to avoid damage to nasal caries.

During collection, the patient should tilt his head back to ensure smooth entry of the nasopharyngeal swab.

It might be accompanied by discomfort and discomfort in the nasal tooth cavity.

Furthermore, nasal bleeding might happen after nasopharyngeal swab collection.

A percentage of blood loss does not call for unique therapy. If the amount of blood loss is huge or lasts for a long time, you must go to the hospital for hemostasis therapy in time.

Additionally, clients with signs and symptoms such as edema as well as blood loss in the nasopharynx should stay clear of nasopharyngeal swab collection to avoid worsening the problem. Before the nasopharyngeal swab collection, you must avoid taking antibacterial and also antiviral drugs to stay clear of impacting the examination results.

Cell medical nasal swab adopts jet nylon fiber implantation technology, which is first-class in the domestic and foreign markets. Such material can absorb more samples.

COVID Swab test : How can I do a Swab Test

Posted on by

From last year to now, the epidemic has changed our way of life. Working from home, quarantine, temporary unemployment, children taking early leave or schooling at home, and less seeing family, friends, and colleagues, many changes require us to adapt.

Since late December 2021, the epidemic in Hong Kong has worsened sharply after the Chinese New Year. On February 5, Hong Kong recorded 300 new positive test cases every day, setting an epidemic record; two days later, the number rose to 607; it exceeded 1,000 for the first time on February 9, and exceeded 2,000 on the 14th.

In the face of the pneumonia epidemic of new coronavirus infection, how should we conduct swab tests? How can we do personal protection in our daily life?

The new coronavirus is transmitted through the respiratory tract, and the pharynx is the place where such viruses gather more. Throat swab samples are medical cotton swabs, which are dipped in a small number of secretions from the pharynx of the human body, and the samples taken are throat swab samples. the virus type.

How can I do a swab test?

Cell medical (Dongguan) Co., Ltd., a professional VTM kits and swabs manufacturer, disposable swab tubes exporter, has many years of experience in medical application molding and flocking treatment heads and swabs.

When performing a swab test, we make the following recommendations to the sampler:

  1. Residents are encouraged to blow their noses to clear their nasal passages.
    If residents cannot perform this task, wipe their nostrils with a flocked swab or tissue.
  2. The Resident’s name, date of birth and time of collection are affixed to the vial.
  3. hand hygiene. Wear a mask, goggles and gloves.
  4. With the head in a neutral position, insert the dry swab from the nostril straight back (not upward) along the base of the nasal passage until it reaches the posterior wall of the nasopharynx—usually halfway from the corner of the nose to the front of the ear (about 4~4~ 6 cm or 1.6-2.5 inches).
  5. Gently swirl the flocked sampling swab and let it sit for a few seconds.
  6. Carefully remove the flocked swab without touching the sides of the nostrils.
  7. Open the virus sampling tube (VTM Tube) and place the swab in the transport medium.
  8. Break the flocked swab along with the swab Breakpoint and close the cap.
  9. Place the sample (viral sampling tube) in the inner bag of the plastic biohazard bag.
  10. Remove gloves for hand hygiene; remove masks for mouth hygiene.
  11. Complete the application form and place it in the small outer bag of the plastic biohazard bag.
  12. Place the entire plastic biohazard bag in a separate clean paper or ziplock bag.
  13. Refrigerated specimens.
  14. shipped to the laboratory.

How can we do personal protection in our daily life?

1. Wash your hands frequently and maintain good respiratory hygiene.

Wash your hands under running water with soap or hand sanitiser.
Practice good respiratory hygiene. Cover your mouth and nose with a tissue or towel when coughing or sneezing, wash your hands after coughing or sneezing, and avoid touching your eyes, nose or mouth with your hands.

2. Enhance physical fitness and immunity, keep the environment clean and ventilated.

Enhance physical fitness and immunity, eat a balanced diet, exercise moderately, work and rest regularly, and avoid excessive fatigue.
Open windows for ventilation no less than 3 times a day, 20 to 30 minutes each time.

3. Minimize activities in crowded places and pay attention to symptoms.

Minimize activities in crowded places and avoid contact with patients with respiratory infections.
If you have respiratory symptoms such as cough, runny nose, and fever, you should isolate and rest at home, and seek medical attention as soon as possible if the fever persists or the symptoms worsen.

4. The role of handwashing in preventing respiratory tract-borne diseases.

Proper handwashing is one of the most effective measures to prevent diarrhea and respiratory infections. The Chinese Center for Disease Control and Prevention, the World Health Organization, and other authorities recommend washing hands with soap and water (water).

5. What should I do if there is no clean water outside the trip and it is inconvenient to wash hands?

You can clean your hands with alcohol-based sanitisers. Coronaviruses are not acid and alkali resistant and are sensitive to organic solvents and disinfectants. 75% alcohol can inactivate viruses, so a certain concentration of alcohol disinfection products can be used as an alternative to soap and running water for handwashing.

 

Do a good job of COVID-19 nucleic acid swab testing, maintain a healthy lifestyle, and do personal hygiene. During the epidemic, follow the principles of going out less, wearing masks, washing hands frequently, actively isolating, and maintaining personal and home hygiene.

A nurse is doing a swab test on a patient

The nasopharyngeal swab test does not produce painful symptoms, and some patients experience discomfort. This inspection is to use a medical flocked swab to enter the nasopharynx to take a small number of secretions and send them for inspection. The pathogenic bacteria can be isolated through bacterial culture. During the operation, the patient will experience mild nausea and discomfort, which is generally within the tolerable range. During the operation, the medical staff is gentle and skilled, so there will be no pain.

Activates unconscious, instinctive reflexes. Depending on the intensity of the body’s response, discomfort, tearing, pain, and other reactions can result. Some people gag, cough, sneeze – it’s all part of the same reflex. For people who are more prone to headaches, this can cause intense discomfort.

Swab testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

A nasal swab refers to a swab deep from the nasal cavity, all the way to the nasopharynx, and the secretion is taken for smearing.

Throat swabs are taken directly from the posterior pharyngeal wall of the oral cavity and the tonsillar fossa by opening the mouth. Nasal swabs are generally slightly more painful than throat swabs because they need to be passed through the nasal cavity. If there are structural abnormalities in the nasal cavity, such as a deviated nasal septum or hypertrophy of the turbinate, or there is hyperplasia in the nasal cavity, such as nasal polyps or the operator does not know much about the anatomical structure of the nose, it is possible that a cotton swab may not easily reach the nasopharynx through the nasal cavity. Partial or damaged nasal mucosa, causing local bleeding or pain and other discomforts.

Nasal swab and throat swab which is painful?

Which is more accurate between nasal swab and throat swab? Essentially, if the operation is standardized, there is basically no difference between the two sampling methods, but we usually eat and drink water, etc., which will reduce the virus accumulation in the oropharynx to a certain extent. , In practice, the positive detection rate of nasal swabs is slightly higher than that of throat swabs. In general, oropharyngeal swabs are suitable for most people and are convenient and fast, while nasopharyngeal swabs are slightly more accurate, but the human body does not feel comfortable.

Precautions before nasal swab testing?

1. Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting;

2. During the inspection, reduce swallowing and do not do throat clearing (such as expectoration and spitting).

3. Pay attention to maintaining a distance of more than 1 meter between people and minimize conversations;

4. Do not drink beverages (including water), smoke, drink, chew gum, etc. 30 minutes before sampling;

5. The tested person should be informed Whether the collection personnel have a relevant past medical history (such as the history of nasal surgery, deviated nasal septum, blood disease, throat disease, etc.);

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab. I see a lot of netizens saying that the nasal swab is very painful and sour, this is because your posture is not correct! !!

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab, their purpose is to let the cotton swab sample from the inner wall of the throat. Nasal swabs are not meant to poke your heavenly lid!

Therefore, you should tilt your head as far back as possible to allow the flocked swab to go in horizontally. That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds. But if you keep your head upright, the cotton swab can only be stabbed from the bottom to the top, which will definitely stab the upper part of the nasal cavity. That position is very sensitive, and it hurts when stabbed. And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

Dog DNA Tests

Dog DNA Tests_The owner is isolated and the pet needs swab test!

Posted on by

A few days ago, a patient in the USA, was diagnosed with a COVID-19 infection. Due to the quarantine, no one at home is taking care of the pet dog. So she turned the dog over to the US Animal Protection Service.

The site is responsible for monitoring animal welfare and controlling animal and plant infectious diseases, such as foot-and-mouth disease, bird flu and other animal diseases.

The staff suddenly wondered if the dog also carried the new coronavirus-19. Therefore, the staff took swabs (secretions and feces) samples from the dog’s mouth, nose and anus for the new coronavirus nucleic acid test.

The new test results were unexpected: the oral and nasal swabs of the new coronavirus-19 were weakly positive in the swab test, and the anal swab test was negative.

However, the symptoms of COVID-19, such as fever and cough, look very lively and healthy.

The transmission of COVID-19 to pets has been the focus of discussion in the scientific community.

Currently, the Society’s Animal Residence has only tested this dog. Not sure if other animals have the same problem.

Subsequently, staff stepped up protective measures for the animal shelter and disinfected its facilities, walls and floors. Out of an abundance of caution, staff also isolate the dogs and observe them closely.

The person in charge of the animal protection station said that the dogs will be re-examined after that.

Although the pet dog had no symptoms of Covid-19 infection, the discovery of suspicious evidence of Covid-19 infection for the first time really took the world by surprise.

The swab test for COVID-19 was weakly positive, with both false positives and positives.

If the dog’s new coronary pneumonia swab test is finally positive, there are two possibilities: one possibility is that the dog is also infected with new coronary pneumonia; the other possibility is that the dog brought the virus into the mouth or Nasal, i.e. mechanical carry.

A dog’s mouth, nose and ground compared to a human. Surfaces with closer contact and smell habits are more likely to inhale some pathogens, including COVID-19 that may be present in the environment.

It is worth noting that the current medical institutions pay more attention to the diagnosis and treatment of infected patients; the CDC pays more attention to the source of the new coronavirus-19 infection and adopts various prevention and control measures. Few institutions test animals that are closely related to people, such as pet dogs, domestic cats, livestock, and even domesticated birds.

Whether these closely related animals carry the new coronavirus disease as a vector of infection or transmission; or whether dogs can be infected with the new coronavirus is unclear.

Dogs themselves can also be infected with coronaviruses, but the common coronaviruses that dogs contract cannot infect humans;

why?

The cat is being made a swab test

The cat is being made a swab test

Generally speaking, a virus needs to enter an animal or human cell in order to infect, replicate, and cause disease.

First, the virus must recognize receptors on the surface of the cell it wants to invade.

For example, SARS-CoV-2 needs to bind to a receptor called angiotensin-converting enzyme 2 (ACE2) to infect humans and cause disease, which is the equivalent of a key to a lock.

The virus then binds to a receptor expressed by the cell, the virus integrates into the cell, and infects the cell.

The ultimate determinant is its genetic material and genes (the material basis is DNA).

Obviously, the DNA of animals and humans is different, and the proteins expressed on the cell membrane are also different. Sometimes it looks the same. As long as

several amino acids are related, the profile of the protein is different and the virus cannot bind to it.

However, this is not absolute, as the virus is constantly mutating and adapting to the environment.

If the new coronary pneumonia can be directly transmitted across species, it can indicate that this virus infection is a zoonotic disease, which is obviously very bad.

A warm reminder from Dr Lee:

We found weak nucleic acid positive for New Coronavirus disease in pet dogs.

This message tells us:

1. In addition to guarding against infection by infected persons, it is also necessary to avoid close contact with active animals, including pets living together for a long time;
2. If you accidentally touch these animals, you must wash your hands afterwards;
3. Wear a mask and do a good job of protection before touching animals as a last resort;
4. During the epidemic, we suggest taking good care of pets and do not take pets for a walk outdoors.

The Mission of A Virus Test Swab

From the sampling point to the testing room, then to the temporary storage point of medical waste.

Then to the hazardous waste centre, to the power plant, and finally to the soil.

A swab for nucleic acid detection completed the task and became a piece of pollution-free ash and fill it in the soil.

At present, we are in a critical period of anti-epidemic.

An ordinary hospital has a maximum of 11,220 samples per day at a single sampling point.

The Mission of A Virus Test Swab

The Mission of A Virus Test Swab

At nine o’clock in the morning, at the nucleic acid testing and sampling service point, citizens who were ready to test lined up.

Everyone wears a mask and consciously separates one meter from each other.

At the beginning of the inspection window, the heavily armed nurses washed their hands with an antiseptic solution.

And then removed a flocked swab about 15 cm long from the packaging bag to take a sample before taking the throat swab.

The nurse opened the collector’s mouth wide, and she skillfully inserted the flocked swab into her pharynx.

Then picked up a sampling tube (virus transport medium) with her left hand. And inserted the collection stick into the sampling tube with her right.

With a little force, the tip of the cotton swab breaks enters the sampling tube, seals it. And throws the long stick into the yellow medical waste bin.

As a testing point for ordinary citizens and inpatients, as an ordinary citizen and inpatients, the use of cotton swabs in an ordinary hospital reached 11,220.

Medical waste treatment forms closed-loop management in nucleic acid testing laboratories.

Take the flocked swab, put the swab head into the sampling tube, and paste a barcode similar to “ID card”. And carefully seal it, put it into a transparent sealed box.

And then send it to the transfer cabin of the PCR laboratory of the Department of Infectious Diseases by staff wearing protective clothing.

The PCR laboratory is under negative pressure, and after the virus enters, it cannot come out. After the outbreak, the PCR laboratory strictly abides by the medical waste treatment process, forming closed-loop management of the laboratory.

An hour later, staff in protective suits transported medical waste out of the ward in sealed yellow bags and sealed with “extremely infectious waste”.

Then, the workers send these medical wastes by trolleys to the medical waste temporary storage area at the nucleic acid collection point 100 meters away. For the medical wastes for nucleic acid testing, he transports an average of about 35 kilograms per day.

We need to place the virus sampling tube for 48 hours during the transfer process

Except for professionals, our PCR laboratory does not allow patients and the public to enter here.

To ensure safety, all medical waste from nucleic acid testing collection points, including swab sticks, is kept here for 48 hours.

After our test results come out and are confirmed to be correct, they will be sent to the hazardous waste treatment centre by a medical waste transfer vehicle.

At ten o’clock in the morning, the staff of the hazardous waste centre arrived at the scene. Unload the empty shipping box and load the ship with medical waste that has been sitting for 48 hours.

The sampling flocked swabs used must be incinerated at high temperatures above 1100°C.

There are two buildings, an incineration workshop and a cooking room, in the yard of the Hazardous Waste Center.

The staff in protective suits skillfully unload boxes of medical waste from the transfer vehicle and load boxes of hazardous waste into bucket elevators.

What to do before the swab test？

Why implement full coverage of DNA swab testing?

What should be paid attention to in DNA testing?

The latest statistics on the COVID-19  released by Johns Hopkins University in the United States on the 9th show that the cumulative number of confirmed cases in the United States has exceeded 60 million.

Nucleic acid detection is an effective method for precise prevention and control.

After the COVID infects the human body, it will multiply in the respiratory system.

Using a nasopharyngeal swab to detect sputum can determine whether the human body is infected with the virus, and can quickly and accurately “find out” the virus.

The recent spread of the epidemic has brought new pressure to epidemic prevention and control around the world. There are even reports of a country’s leader being positive for the new crown. Mexican president tests positive for coronavirus. The President of Paraguay has tested positive for the new crown. Poland: President tests positive for coronavirus. Brazil’s president tests positive for coronavirus. etc.

On the basis of continuing to perform nucleic acid testing on key groups of people, close contacts, etc., to identify the infection chain as soon as possible, block the transmission route, control the spread of the epidemic, and implement large-scale full nucleic acid testing, we must achieve early detection, early reporting, Early isolation, early treatment, active search for potential new coronavirus infections, and targeted prevention and control measures are also adopted to protect the health of the masses, ensure the rational flow of the population, and maintain the stable development of social and economic life order. It is very important. significance.

What methods are available for COVID swab testing?

Nucleic acid detection generally adopts the nasopharyngeal swab detection method, including nasopharyngeal swab detection and oropharyngeal swab detection.

At present, most hospitals and institutions in our city use oropharyngeal swabs.

This method is the least painful and more convenient to collect samples.

Is it painful to take a throat swab?

A throat swab is a method of collecting a specimen from the throat area, it is painless, mild nausea or sore throat method, which can be relieved or disappear quickly after collection.

Are DNA tests dangerous to humans?

There is no harm to the human body, only when the throat swab is collected, a slight foreign body sensation will be felt when the cotton swab enters the throat.

What should I pay attention to before and after the inspection?

Before detection

Before the nucleic acid test, it is best not to eat for 2 hours, otherwise, it will cause vomiting.
Do not drink water, smoke, drink, or chew gum 30 minutes before sampling.

Before the examination, reduce the number of swallowing movements, and do not do throat-clearing movements, such as expectoration and spitting.

For example: before the nasopharyngeal swab collection, the subject should provide the collector with the relevant past medical history or related matters.

Such as history of nasal surgery, nasal septum, blood disease, throat disease, or taking anticoagulant drugs.

Be sure to wear a mask before going to the test, take out the mask before the test, and put it on immediately after the test. You can prepare a spare mask, which can be replaced at any time after pollution.

Checking

When collecting oropharyngeal swabs, the subject should tilt his head back, relax as much as possible, take a deep breath, and open his mouth to make an “ah” sound, which will help reveal the throat, but symptoms such as irritating dry cough, nausea and vomiting may occur during this process.

Nasopharyngeal swab During the process of nasopharyngeal swab, symptoms such as swelling, itching, and sneezing may occur, which can be covered with a tissue or elbow.

After detection

Leave the collection site immediately after collection to avoid spitting and vomiting near the collection site.

You must pay attention to hand hygiene before and after the nucleic acid test.

You can wipe your hands with your hands, or you can use hand sanitiser, disposable alcohol, and disinfectant cotton pads.

 

Important reminder:

●Be careful to wear a mask, do not expose your nose and nose, do not take it off at will, or pull the mask to your chin.
●There should be an orderly queue, keep a distance of 1 meter, do not get together, do not gather.
●When waiting in line for a long time, pay attention to sun protection, sun protection, scientific hydration, and a reasonable diet.
● Try to avoid taking public transportation to the nucleic acid test sampling site.

The current situation of epidemic prevention and control is very complicated.
Every day, take care to protect your body.
Wear a mask and follow the epidemic prevention regulations.
Protect yourself and protect others at the same time.
New coronavirus pneumonia cases.
Please accept the general guidelines for prevention and control.
Daily Travel Prevention Control Guidelines.
Take the bus, take the subway.
To minimise contact, payment can be made using a transport card or a mobile app.
Avoid touching public facilities such as seats, armrests, car doors, and armrests with your hands as little as possible. If you do, do not touch your mouth, eyes, and nose directly with your hands, and disinfect your hands in time to avoid contact infection.

Hospitals and other places, after returning home, you should disinfect your outerwear.

01. What is nucleic acid detection?

At present, nucleic acid detection is the main method for laboratory diagnosis to determine whether a patient is infected with the new coronavirus. It can achieve early detection, early diagnosis, and early treatment. Real-time fluorescent PCR can be used to detect throat swabs, sputum or blood samples. to covid nucleic acid, or detected by viral next-generation gene sequencing.

simply put

Nucleic acid testing is done by

After collecting human secretions

Tested by the instrument

to see if we have the new coronavirus in our body

If so, the test result is positive

On the contrary, if it doesn’t, it’s negative.

02. How to test the COVID swab?

“Sir, oropharyngeal swab, nasopharyngeal swab, and anal swab, which one to choose?”

How do you do a nasopharyngeal swab?

Nasopharyngeal swabs must be performed with the patient sitting upright with the head in an upright position, as this allows for easy visualization and access to the nasal floor perpendicular to the central axis of the patient’s face.

Insert the swab into the patient’s nose and align it parallel to the nose and the base of the septum. As long as there is no obstruction in the nasal cavity, the swab continues to move in this direction until it reaches the nasopharynx, at which point the tester feels resistance.

Once the swab reaches the nasopharynx, a gentle rotation and two complete 360-degree rotations are recommended to allow secretions from this area to be absorbed.

Once the swab is removed from the patient’s nose, it is immediately inserted into a viral sample containing a viral transport medium. The handle of the swab extending through the opening of the vial was broken off to allow the tube to be closed.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions
Let’s take a look at their respective advantages and disadvantages

The specific operation of the anal swab is as follows:

Soak a flocked swab in saline, insert it 2-3 cm into the anus, wipe from the folds around the anus, or rotate it gently inside the anus, and insert it into a test tube containing saline.

anal swabs

For fecal swab cultures, all of the above requires the use of sterile equipment and placing the swab in a sterile tube.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions.
Let’s take a look at their respective advantages and disadvantages.

Oropharyngeal swab: relatively simple to operate, less irritating, suitable for large-scale screening. Therefore, the nucleic acid test of oropharyngeal swabs is mainly used in the screening of new coronary pneumonia for the epidemic-related population, which is used in the routine nucleic acid test clinic of the First Affiliated Hospital of NTU.

Nasopharyngeal swab: The technical requirements are high, the human body does not feel comfortable, and the accuracy rate is higher than that of the oropharyngeal swab. However, for some asymptomatic or mildly infected people, the condition recovers quickly after infection, and the pharyngeal nucleic acid may not be detected in 3 to 5 days.

Anal swab: high accuracy, reduce missed diagnosis. The study found that the duration of nucleic acid-positive feces or anal swabs of some infected persons is longer than that of the upper respiratory tract. Therefore, anal swab tests will be carried out for key groups such as isolation points or some imported overseas.

In conclusion.
The three swabs have different lengths.
If you have to test an anal swab.
Don’t be shy.
Whatever the swab,
It is a good swab that can accurately identify the virus.
