Nasopharyngeal Swab Collection Instructions

Posted on 2022年2月24日2022年3月22日 by Dr. Lee

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

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

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.

Nasopharyngeal Swab Pcr Test

Posted on 2022年2月21日2022年3月22日 by Dr. Lee

Nasopharyngeal Swab Pcr Test

There are two broad categories of COVID-19 tests: viral diagnostic tests (which detect an active COVID-19 infection) and antibody tests (which detect past COVID-19 infections).

The PCR swab test is a qualitative oropharyngeal or nasopharyngeal collection used to detect the novel coronavirus, the virus that causes COVID-19. This test helps determine if you have been exposed to the virus. The COVID-19 PCR test is a molecular test that detects the genetic material of the virus.

The current more accurate test for COVID-19 is to use RT-PCR to assess the presence of SAR-CoV-2 RNA in collected samples. If anything, the subject was almost certainly infected with the virus.

On this page you will learn about:

What are the diagnostic tests for the COVID-19 virus?

Mouth swab vs Nasal swab

What are the diagnostic tests for the COVID-19 virus?

With the development of testing for COVID-19, there are now four main forms of diagnostic testing for the virus:

Nasal Swab Test: A test involving a shallow nasal flocked swab.

Cell medical flcoekd swab

Nasopharyngeal test: A test that involves a deeper nasal swab using PCR technology.

Saliva Test: A test involving a saliva sample and PCR technology.

Oral swab test: An innovation in COVID-19 testing that allows anyone to test quickly, non-invasively and easily. Use PCR technology.

The COVID nasal swab test, also known as the nasal swab test, is a medical test used to detect viruses in the nose that can cause respiratory infections.

How does Nasopharyngeal Swab detect coronavirus?

Nasopharyngeal testing collects a sample from the back wall of the nasopharynx.

(1) Measure the distance from the nostril to the base of the ear with a swab and mark it with your finger.

(2) Let the patient’s head relax naturally, put the swab against the nostril wall and slowly rotate it into the patient’s first nostril to the nose and palate, and then slowly take it out while wiping. With the same swab, leave the swab in the nose for 15-30 seconds, then gently swirl 3 times. Wipe the other nostril in the same way;

(3) Put the flocked swab into the virus delivery medium, break the swab rod, and place it completely in the tube.

(4) Tighten the cap of the tube, make a mark, put it in a plastic bag and seal it

(5) If it is necessary to collect from both nostrils, a swab should be used separately.

(6) Store at 4°C (short-term storage).

What types of nasal swab sampling are available?

There are three types of sampling swabs used in the nasal cavity, namely nasopharyngeal swabs, nasal cavity swabs, and middle turbinate swabs.

nose structure

Nasopharyngeal testing collects a sample from the back wall of the nasopharynx.

Sampling from the middle turbinate location is not as uncomfortable as the nasopharynx.

Anterior nasal swab/nasal swab:

Taking a sample in the anterior position of the nose does not cause discomfort and can be used by people with narrow nasal passages.
The sampling difficulty is low, and the patient can easily complete the anterior nose sampling by himself.

Although nasopharyngeal swabs, nasal swabs and turbinate swabs have different sampling methods, they can all be used to collect samples and then use PCR results to determine whether the owner of the sample has been infected with the new coronary pneumonia virus.

Do you feel any discomfort? Does it hurt!

Nasopharyngeal Swab Sample

Nasal swabs and throat swabs are the two most widely used sampling methods. Just use a flocked swab to gently wipe the throat mucosa or nasal mucosa, and it can be completed in 1 to 2 seconds, which is generally not uncomfortable. However, for some more sensitive people, irritating retching, nausea or choking may occur. At this time, it is best to use a tissue to cover the mouth and nose and try to hold it back to avoid vomit or sputum. create pollution.

How does nucleic acid testing relieve the discomfort of sampling?

Both nasopharyngeal swab sampling and oropharyngeal swab sampling will make the sampled person feel slightly uncomfortable, which can be relieved after a short rest. Therefore, during the sampling process, the sampled person should cooperate with the sampling personnel as much as possible, relax as much as possible, and do not move the head excessively to avoid scratching the mucous membrane with the sampling swab.

Is the nasal swab COVID test the best test?

What are the current testing methods for COVID-19?

There are two types of virus detection:

Nucleic acid amplification test (NAAT) (PCR test) and antigen test.
Antibody tests (also called serology tests) can show whether you have been infected in the past.

Mouth Swab vs Nasal Swab

HOW TO USE

Nasal swabs generally enter from the nasal cavity and take the secretions at the back of the nasopharynx, while pharyngeal swabs enter from the mouth to the throat and take local secretions for inspection, that is, the two enter in different ways.

Viral Transport Medium Tube

Posted on 2022年2月18日2022年2月18日 by Dr. Lee

Viral Transport Medium Tube

A virus sampling tube is a product used to collect and transport infectious disease specimens. It is not a single product, but a set consisting of a sampling flocked swab, Viral Transport Medium and a plastic tube. Sampling process: use a swab to sample the patient, but the preservation solution into a plastic tube, put the sample into the plastic tube preservation solution, and transport the preserved sample to the laboratory for testing.

Special instructions for virus sampling tubes:

If the collected sample is used to detect viral nucleic acid, it must be used with a nucleic acid extraction kit and nucleic acid detection reagent; if it is used for virus isolation, it must be combined with a cell culture medium.

Different application fields have different requirements on the volume of sampling liquid, please replace the corresponding product according to the prompts in the sequence information:

Viral sampling tubes that collect viral samples from clinical patients generally require less fluid.

For a collection of single-use virus sampling tubes and short-term delivery of influenza virus from the external environment. We typically require a liquid volume of 3 to 6 ml.

Virus sampling tubes have three requirements, including transport, storage, and sample usefulness.

Transportation, ensure that the samples do not leak during transportation;

Preservation, ensure that the sample does not leak during the preservation process;

In terms of the usefulness of the sample, the sampling tube itself does not have a toxic effect on the sample, so as not to affect the material collected in the sampling tube, which in turn affects the test results.

What is vtm kits?

Viral Transport Medium Tube

Cell medical (Dongguan) Co., Ltd.’s disposable nasopharyngeal VTM sampling kit is a nasopharyngeal swab sample collection for COVID-19 detection. The kit contains a virus transport medium (VTM) for nucleic acid detection and virus culture. It can be stored at room temperature before collection and should be stored at 2-8°C after collection to avoid the growth of contaminants.

Flu Swab Test

Posted on 2022年2月8日2022年3月22日 by Dr. Lee

Influenza, commonly known as influenza, is an acute respiratory disease caused by influenza A, B, and C viruses, and belongs to Class C infectious diseases. Influenza is an illness that spreads relatively easily from person to person and can infect large numbers of people. While most people recover quickly from the flu, some, such as older adults, are at risk of serious illness and even death.

Flu Swab Test

Influenza viruses come in many different forms. A flu swab is a method of taking a sample from a person. Medical staff check patients for flu. If so, what kind of flu virus can be spread by inhalation through the nose and throat of an infected person.
When the flu virus infects a person, it spreads through the respiratory tract. The nose and throat are where the virus lives and grows, causing symptoms such as a runny nose, sore throat and cough. These places are also the easiest places for doctors to obtain samples. As a result, doctors can often use flu swabs to determine whether a patient has the flu, which often spreads quickly in a population.
Due to public health, some government medical agencies may wish to track the spread of the disease. Since influenza viruses also mutate rapidly, new influenza viruses are produced regularly. The type of flu a person has can also be important information for the public health system.
Finally, a doctor may need to determine whether a person has the flu so an appropriate treatment plan can be instituted. There are several ways a doctor can use a swab to determine if a patient has the flu virus. An area of medical professionals, usually to test for microbes. (Nasal swab for flu)

A sampler is doing a swab test for a woman

How to Swab for the Flu?

They usually have a long swab stick with a soft swab tip at the end, made of cotton material, polyester, polyester or rayon tip, nylon flocked swabs. is sterile, so the test only analyzes the microbes in the sampled area. During the flu swab procedure, doctors usually insert the end of the swab into the patient’s nose and spin the flu swab to collect as much mucus as possible.
A doctor can take a sample by inserting a swab into the top of the throat through the nose. If the virus grows heavily in the area, the flu can cause dizziness.
Doctors have several different ways to test a cotton swab for the flu virus. The test that takes a few days to a week to complete is a viral culture, in which viral particles are grown in human cells.
Rapid tests include tests that analyze the sample for the presence of genetic material or antigens from the flu virus. An antigen is a special molecule in a virus. Some commercial tests contain antibodies, and the presence of antigens can be recognized by their linkage to the antigens.
These tests are less than an hour, but may not be as accurate as viral cultures. A runny nose and sore throat can be symptoms of the flu.

How do I know if I have the flu?

If you have a fever, cough, sore throat, runny or stuffy nose, body aches, headache, cold and/or fatigue, your respiratory illness may be the flu (flu). Some people may experience vomiting and diarrhea, although this is more common in children. People can get the flu without having a fever. Influenza viruses usually cause the most illness during the colder months of the year. However, the flu can also occur outside of a typical flu season. In addition, other viruses can cause flu-like respiratory illnesses. Therefore, it is not possible to tell if you have the flu based on symptoms alone. If your doctor needs to determine if you have the flu, you can do laboratory tests.

Can I get the flu and COVID-19 at the same time?

Yes. Co-infection with influenza and other respiratory illnesses, including COVID-19, is possible. Health experts are still studying how common the condition is.

The flu is similar to some of the symptoms of COVID-19, so it’s hard to tell them apart based on symptoms alone. The swab diagnostic test helps determine if you have the flu, COVID-19 or other respiratory infections.

What is Pooled Sample Test?

Posted on 2022年1月20日2022年1月20日 by Dr. Lee

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.

What to do before swab test

Posted on 2022年1月19日2022年3月22日 by Dr. Lee

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.

Covid Mouth Swab Test

Posted on 2022年1月12日2022年3月22日 by Dr. Lee

Covid Mouth Swab Test

Three key points for oral swab collection!

The oral swab is an all-in-one system that can collect, stabilize, transport and purify DNA from saliva in advance, providing a painless and risk-free new way to collect microbial DNA for disease control and prevention.

Accidentally, it is easy to cause people to be infected with the new coronavirus, and the surface detection is not sensitive, and the operation is easy to lead to standardized operation.

Awareness Check Tool:

Testing equipment for testing equipment, including testing tools for testing equipment, testing equipment for testing equipment, testing equipment for testing equipment, including safety testing equipment.

Virus Sampling Tube & Nasopharyngeal Swab (Inactivated)

Oropharyngeal sampling points:

1. Sufficient light: Good lighting should be provided for both indoor and outdoor light sources. If necessary, flashlight lighting should also be provided.

2. Full exposure: The three anatomical locations for oropharyngeal swab collection must be completely exposed, and a spatula should be used when exposing bilateral tonsils.

3. Accurate location: The oropharyngeal swab should not touch other parts, such as the tongue, chin, etc., except for the three designated locations, so as not to be stained with saliva and affect the quality of specimen collection.

Covid Mouth Swab Test Pre-harvest preparation

Routine screening:

Work clothes, medical protective face shield, work cap, gloves, isolation gown, goggles (anti-fog) or face shield.

Influenza or suspected cases:

Wear work clothes, medical protective masks, work caps, gloves, isolation gowns or protective clothing, goggles (anti-fog) or protective face shields, and add shoe covers or boot covers if necessary.

Order of protective clothing:

Work caps that do not need to be worn. → Protective masks (Wearable head-mounted type and a tightness test should be performed after wearing them.)→ No shoes protective clothing (Boot covers should be added instead of foot protective clothing.) → Surgical gloves. → Protective screen or goggles.

Employee Registration Protection:

Tooling or isolation gown. → Medical-surgical mask or medical protective face shield. → Disposable work cap.

Protective clothing should be replaced every 4 hours and should be replaced in time if there is moisture or pollution.

Supplies preparation: Throat swab sampling sleeve, tongue depressor, inspection sheet and barcode, transport bag or refrigerator, 75% alcohol, pen.

Nucleic acid collection

1. We asked the examinee to tilt his head slightly, open his mouth.

And lift the upper jaw vertically to expose the posterior pharyngeal wall.

2. Use the front end of a sterile long cotton swab to quickly rub up and down 3-5 times on the bilateral pharyngeal tonsils.

And 3-5 times on the upper and lower sides of the posterior pharyngeal wall.

3. After scraping, open the sampling tube. Insert the front end of the sample vertically into the sampling tube. Insert the sampling tube. Break the sampling tube to expose the outer part of the tube. And tighten the cap.

Place the sampling tube in a biosafety sealed bag, mark the name and other information on the sampling tube, and complete the sampling.

Notice:

1. When sampling with the Covid Mouth Swab Test, it is best not to call “ah”, because once the sampled person is a positive patient, he will shout “ah”, exhale the virus in large quantities, and form aerosols in the sampling area.

When sampling, we advise patients to open their mouths and not yell or take deep breaths.

2. During the sampling process, one person collects and one person disinfects.

When the sampler holds the cotton swab, try to take it as far as possible.

3. A large number of samplers collect oropharyngeal swabs face-to-face with the sampled person.

Therefore, during the sampling process, the breath exhaled by the patient can easily and directly pose a great threat to the medical staff.

To reduce the risk of the sampler, we recommend that healthcare workers sample at a 45-60 degree angle to reduce risk.

End of Swab Test sampling

1. Spray and disinfect the generated medical waste layer by layer, and tie the gooseneck double medicine bag tightly to ensure that the seal is tight, has no damage, and has no leakage. Do not squeeze the contents of the medical waste bag. Annotation generates point information.

2. The order of unprotected items: hand hygiene → take off the protective face shield or goggles → hand hygiene → take off the protective clothing (take off the boot cover together) → hand hygiene, take off gloves, hand hygiene → take off the protective mask and Disposable work cap → hand hygiene.
