Flocked Swabs and Custom Swab Manufacturing

When it comes to flocking sampling swabs, many people may only know that they are used for sampling by name, but they may not know the specific details. So what are flocking sampling swabs usually used for?

COVID-19 Testing Sampling

Throat swab: Professional operation is required, because the throat is more prone to injury, flocking swabs are the first choice.

1. What is a flocking swab?

Flocking refers to the process of applying multiple lengths of fibers to an adherent coated surface; if the tip of the swab is flocked, it is a flocked swab. It is a disposable sampling swab composed of nylon short fiber fluff head and abs plastic rod. For oral nasopharynx, sampling, cervicovaginal sampling, laboratory testing, etc.

Flocked sampling swab samples are easy to collect.

Flocked sampling swab samples are easy to collect.

2. What are the advantages of flocking swabs for DNA collection?

Sample collection process: The unique structure of the flocked swab tip can greatly increase the number of samples collected

Sample extraction process: The brush-shaped layer structure can release approximately the entire collected sample.

3. Why use flocking sampling swabs? You will know after reading the comparison below.

Conventional fiber swab: The sample is trapped by the gaps in the fiber mass, that is, the sample is penetrated, diluted, and trapped in the fiber. The acquisition is slow, the release is even slower.

 

 

 

Nylon flocked swabs: Superior sample collection/release capability, >80% release rate

The time for flocking swabs to collect samples is 3-5 seconds, while the time for cotton swabs is 15-120 seconds, or even longer, which causes pressure on staff during the diagnosis process. Only faster sample extraction can complete the collection and analysis more efficiently.

3. Why are flocking swabs more advantageous for micro DNA collection?

Due to the internal structure of traditional cotton swabs, which are entangled with cotton fibers at the top, the sample will be dispersed by its fiber clusters and remain in the fibers during sampling, resulting in lower precipitation efficiency of DNA with low content, and even causing false negatives in the test. result.

The unique structure of the top of the flocking swab can almost completely extract and separate out a very small amount of DNA, so the flocking swab has a more obvious advantage in the collection of trace DNA.

Swab Step 1: Hold the handle and gently insert the sampling swab into the mouth.

Step 2: Gently rotate the sampling swab for 3-5 turns, then slowly take it out

Step 3: Put the extracted sample into the sample collection tube, break the handle, and seal it immediately to complete the sampling.

The newly developed sampling swab nylon flocked sampling swab head has soft flocking hair, and the absorption and release force is 3 times greater than that of trapping microorganisms in traditional sampling swabs, and it will not cause epithelial damage to patients.

The short nylon fibre acts like a soft brush, which can effectively improve the collection of cellular material; the capillary movement between the fibers forms a strong hydraulic pressure, thereby ingesting the liquid sample; at the same time, the sample is close to the surface of the swab and is easy to elute.

Monkeypox Virus Outbreaks Are Containable

Monkeypox Virus Outbreaks Are Containable

Monkeypox Virus Outbreaks Are Containable, WHO said available details indicated that human-to-human transmission was occurring among people who had close physical contact with symptomatic cases. The patient’s symptoms were similar to those observed in smallpox patients in the past but were less clinically severe.

These confirmed and suspected cases are mainly from the United Kingdom, Spain and Portugal, with the rest in Australia, Belgium, Canada, France, Germany, Italy, the Netherlands, Sweden and the United States.
 The incubation period for monkeypox is usually 6 to 13 days, but it can be between 5 and 21 days.
However, Nick Finn, deputy director of England’s National Infectious Service, stressed that monkeypox does not spread easily from person to person and that the overall risk to the public is low.
An expert from China’s disease control system also told Caijing·Great Health that the spread of monkeypox between people can be said to be very limited, mainly through secretions and other transmissions, and the risk of causing an epidemic is very limited.
How serious is a monkeypox infection?

Before the current outbreak, monkeypox cases scattered in the tropical rainforests of central and western Africa.

Monkeypox Virus VTM Kits

Monkeypox Virus VTM Kits

There are two distinct clades of monkeypox viruses, the Congo Basin clade and the West African clade. Monkeypox, caused by the Congo Basin clade virus, has reported a mortality rate of up to 10.6%; while the West African clade virus, which usually causes less severe disease, has a case fatality rate of 3.6%.
In this outbreak, all cases with samples confirmed by polymerase chain reaction (PCR) testing were determined to be infected with the West African branch, meaning relatively low mortality.
The genome sequence of a swab sample from a confirmed case in Portugal showed that the monkeypox virus responsible for the current outbreak closely matched cases exported from Nigeria to the UK, Israel and Singapore in 2018 and 2019.
Initial symptoms of monkeypox infection include fever, headache, swelling, back pain, muscle aches and general weakness. Infected individuals initially have generalized erythema or rash, which then develops into papules on the trunk, face, palms, and soles, which then develop into cysts, which form pus scars and scabs. Sometimes a bit like chickenpox, the infection lasts 14 to 21 days and usually goes away on its own.
The virus can enter the body through broken skin, the respiratory tract, or through the eyes, nose, or mouth. Evidence suggests that the highest risk of infection is in people who have had close physical contact with a symptomatic monkeypox patient.
Of the first nine cases of monkeypox confirmed in the UK, six had had sex with men.
To date, severe cases are more common in children and immunocompromised people, especially those with HIV, and are related to the degree of exposure to the virus, the patient’s health status, and the severity of complications.
Hans Kruger, WHO Regional Director for Europe, also said: “Monkeypox is usually a self-limiting disease and most infected people recover within a few weeks without treatment. 

How to get out of Africa and into Europe?

Confusingly, monkeypox occurs primarily in the rainforest regions of central and western Africa. For example, the US recorded two cases of monkeypox in 2021 and the UK reported seven cases, all imported to and from Nigeria. travel history.
However, in this outbreak, it is unusual for confirmed and suspected cases reported in several countries without any travel history to monkeypox-endemic areas.
Australia, Canada and the United States are also among the non-endemic countries reporting monkeypox cases. Health authorities in New York City, home of the United Nations, are also investigating a possible case. A patient at a hospital tested positive on May 19, local time.
These cases are atypical, Hans Krueger said. All but one were not related to travel to monkeypox-endemic countries.
WHO believes that there is an urgent need to raise awareness of monkeypox and implement comprehensive measures to detect and isolate cases, trace contacts, and provide supportive care to limit further spread.

How to stop the spread.

“China has not reported any cases of monkeypox, nor has the virus been found in animal hosts. The current focus is on preventing imported cases,” Tan Wenjie, a researcher at the Chinese Center for Disease Control and Prevention’s Institute for Viral Disease Prevention and Control, said in an interview with the media. (Transport medium )
According to the above-mentioned experts of China’s CDC, at present, the measures to prevent the importation of the monkeypox virus are very strict.  Import squirrels, rabbits and other rodents. The possibility of monkeypox being introduced by animals brought by inbound passengers is unlikely and the public need not worry.
Specifically, researchers don’t yet know the animal reservoir of the monkeypox virus.
Since 1970, the monkeypox virus has had sporadic outbreaks in 10 African countries. This is a DNA virus in the genus Orthopoxvirus of the Poxviridae family. In 1958, a group of captive monkeys transported from Africa to Copenhagen, Denmark for scientific research developed the vesicular disease. European scientists isolated the monkeypox virus from monkeys in the laboratory, hence the name “monkeypox virus”.
In 2017, Nigeria experienced its largest outbreak on record. At that time, there were 172 suspected cases, and 75% of the patients were men, aged 21-40. Since then, Nigeria has continued to report monkeypox cases.
 Of these, 241 were confirmed cases, including 8 deaths (case fatality rate 3.3%). From 1 January to 30 April 2022, 46 suspected cases were reported and no deaths were recorded.
In 2003, there was an outbreak in the United States, the first time the disease had emerged outside of Africa. The patient was infected due to close contact with marmots. Marmots were infected by various small mammals imported into the United States. There were 81 cases at the time, but there were no deaths.
The cases of monkeypox infection have emerged in multiple countries, and researchers suspect that transmission may have continued for some time because all but one of these cases were not related to travel to monkeypox-endemic countries and were geographically dispersed in Europe and elsewhere.

Matthew Kavanagh, acting deputy executive director of WHO’s AIDS agency, stressed on May 22 that leaders urgently need to strengthen their pandemic preparedness. Including building stronger community-led capacity and human rights infrastructure to Support an effective and de-stigmatizing response to the outbreak.

The above-mentioned experts in the disease control system explained to Caijing. 

However, the “early detection” of the monkeypox virus is difficult. The above-mentioned experts in the disease control system said that it takes a certain period of time for monkeypox infection to have clinical symptoms and thus be discovered, which is different from the emergence of viral symptoms in respiratory infections.

COVID-19 Swab Test: What you should know

COVID-19 Swab Test: What You Should Know

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 are flocked swabs used for?

Flocked swabs are widely used in Covid Test bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic-based tests, and forensic identification. Both are ideal.

For throat sampling of respiratory viruses such as influenza, swine flu, bird flu, hand, foot and mouth.

Vtm Kits are used for the collection, transportation and storage of influenza, avian influenza, coronavirus and other virus samples for subsequent extraction and PCR amplification.

After samplers collect virus samples, they usually do not conduct PCR testing at the sample collection site in time.
So the collected virus flocking swab samples need to be transported. The virus itself will rapidly decompose in vitro, affecting subsequent detection. During transport, we need to add a virus preservation solution (virus transport medium).
For different detection purposes, we need to use different virus preservation solutions.
At present, it mainly includes inactivated type and non-inactivated type. In order to meet different detection requirements and different laboratory conditions for virus detection, it is very necessary to use different preservation solutions.
Flocked Sterile Swabs

Sterile Flocked Nasopharyngeal Swab, 100% nylon flocked swab that provides exceptional absorption quality.

The principle of flocking swab precipitation.

1. Through the directional friction effect of the fiber layer of the flocked swab, the laboratory operator can complete the cell sample.

The unique structure of the top of this swab can greatly increase the number of samples collected

2. Flocked Swab is ideal for collecting large amounts of cells & rapid elution of the specimens instantly released into the transport medium.

More than 95% sample release rate. Very easy to elute.

3. The capillary movement between the nylon fibres at the top of the flocking swab forms a strong hydraulic pressure for absorbing liquid or cell-like samples.

Why flocked swabs are more beneficial for micro DNA collection.

1. The top of the traditional cotton swab, may even lead to false-negative results of the test.

2. The top of the flocking swab has a unique structure, which can almost completely extract and separate trace DNA, so the flocking swab has more obvious advantages in collecting trace DNA.

Made of non-inhibitory DNA amplification materials. It has been verified that it can be directly amplified by PCR, eliminating the need for extraction steps.

About viral transport media

At present, it mainly includes two types: inactivated and non-inactivated.

Flocked Swab With Vtm Kits Leading China Manufacturer

Flocked Swab With Vtm Kits Leading China Manufacturer

Inactivated preservation solution:

It can lyse and inactivate the virus in the sample so that the virus loses its infectious activity.

It can effectively prevent the secondary infection of operators.

But it also contains inhibitors, which can protect the viral nucleic acid from degradation.

Therefore, the experimenter can perform follow-up detection by NT-PCR.

Stored at room temperature for a long time, saving the storage and transportation costs of virus samples.

Non-inactivated preservation solution:

The non-inactivated preservation solution of the present invention can maintain the in vitro activity of the virus and the integrity of the antigen and nucleic acid, protect the viral protein shell, and maintain the originality of the virus sample to a large extent.

Not only for nucleic acid extraction and detection (PCR test) but also for virus culture and isolation.

  The CellMedical virus sampling tube has a thickened and leak-proof design to ensure that the sample does not leak during transportation. It is a virus transport medium (VTM KITS) that complies with WHO regulations and biosafety regulations.

What is viral transport medium ?

Viral transport medium is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling and is usually called virus preservation solution in China.

Usually, in nucleic acid testing (PCR swab test), we cannot perform nucleic acid PCR directly at the sample collection site.

We need to add virus preservation solution (VTM) to the samples collected by swab for transfer check.

What is a virus?

Viruses are microorganisms whose structure is very simple.

There is no way to complete the process of self-replication.

They need the help of host cells and the nutrition of the host to complete virus replication.

The virus can infect humans as well as many other animals.

Influenza viruses such as common infectious diseases are usually RNA viruses.

There are many common viruses that cause human infection, which can cause respiratory diseases, such as cold virus, influenza virus, HIV and influenza A virus.

Since it has no cellular structure of its own, the virus itself cannot replicate.

But invades the gene into the host cell and replicates the new virus with the help of the latter’s replication system.

In conclusion, viruses are diverse and can cause damage to multiple parts of the body.

After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the sampling swab ( flocking swab ) will be put into the preservation solution ( viral transport media ) for preservation and transportation.

What is the viral transport medium used for?

pcr test

PCR test

The inactivated viral transport medium can perform protein denaturation on fresh clinical virus specimens to inactivate the virus. Prevent secondary infection and ensure the safety of transportation and testing personnel. The inactivated samples can be used with a variety of virus extraction kits.

The nucleic acid extraction instrument can quickly extract nucleic acids.

At the same time, with the respiratory pathogen PCR detection kit (VTM Kits) to achieve rapid detection. The specificity and sensitivity are not affected.

Virus preservation solution has many functions:

1. The operation is simple, and the liquid contains ingredients that can denature proteins, thereby inactivating the virus;

2. Contains inhibitors to protect the stability of viral nucleic acid to a greater extent and greatly improve the nucleic acid extraction rate;

3. Stored at room temperature for 12 months before sampling.

The airtightness is good, which is convenient for storage and transportation and saves transportation costs.

Viral transport media include inactivated and non-inactivated viral transport media.

Contains Hank‘s Liquid, Potassium Chloride, Magnesium Chloride, Calcium Chloride, BSA, etc. The combination of various antibiotics has antibacterial and antifungal effects.  Bovine serum albumin (BSA), as a protein stabilizer, can form a protective film on the protein shell of the virus. Making it difficult to decompose and ensuring the integrity of the virus; Hank’s buffer The neutral environment constructed by the agent helps to increase the survival time and infection stability of the virus.

Anterior Nasal Swab VS Nasopharyngeal Swab

Nasopharyngeal Swab

Inactivated and non-inactivated virus preservation solutions: usually used for the collection and transportation of clinical influenza, avian influenza, hand, foot and mouth virus, measles and other virus specimens, as well as specimens such as mycoplasma, ureaplasma, chlamydia, etc.

1. For monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments.
It is suitable for a sampling influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses.  
2. To transport nasopharyngeal flocked swab specimens or tissue specimens from specific parts from the sampling site to the testing laboratory for PCR extraction and detection.
3. Preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture.
Flocked Swab Influenza

Flu Flocked Swab Influenza

Influenza refers to the common cold, which is an acute respiratory infectious disease caused by the influenza virus.

It is highly contagious and mainly spreads through droplets, such as coughing and sneezing. Influenza generally occurs in winter and spring.

The current influenza detection method is the rapid influenza antigen detection method, which detects “flux A” and “flu B” antigens.

Laboratory staff collect samples through throat swabs.

In fact, in inspection work, it is important to know the quality of the specimen in order to obtain accurate and reliable results.

Throat swab specimens: Professionals can avoid many false-negative influenza tests caused by improper specimen sampling.

The precautions for flu throat swabs are basically the same as those for nucleic acid detection throat swabs. Because the same part is sampled.

There are two types of flu throat swabs: nasopharyngeal swabs and oropharyngeal swabs.

What precautions should I take when taking a throat swab test for flu?

1. Oropharyngeal swab The collection method of the oropharyngeal swab is to let the subject open his mouth, then use a long pharyngeal swab to wipe the patient’s pharynx, bilateral frontal arches and tonsils, and take out the local secretions. Into the catheter of the throat swab and sent to the laboratory for testing.

2. Nasopharyngeal swabs The collection method of nasopharyngeal swabs is to use sterilized throat swabs to penetrate deep into the nasal cavity of the subject and reach the nasopharynx, and extract secretions and nasopharynx by rotating or wiping.

Epithelial cells put a section with secretions and epithelial cells into a sterile container and then carry out pathogenic detection.

Flu swab material

Swab options for flu testing include flocked swabs, cotton-tipped swabs, rayon tipped swabs, and foam-tipped swabs.

Cotton tip swab:

The original swab tips were all cotton, mainly based on their cleaning power and water absorption. Cotton swabs are very inexpensive and readily available, and are widely used in medical wound management after sterilization with ethylene oxide or autoclaving, as well as in forensic crime scene forensics. In the absence of alternatives, cotton swabs can be used in almost a variety of scenarios.

However, cotton-tipped swabs also have some problems. Due to the low release rate of cotton, natural material for samples, and some of the natural fatty acids in it can damage microorganisms, they are less and less used for sample collection.

Rayon head swab:

Rayon—a synthetic fiber made from wood pulp. Although classified as synthetic fiber, it is essentially a natural material. Compared to cotton, rayon is produced during the process of removing substances that may damage the sample or react with the sample during transportation and handling , so it is generally used for sampling for diagnostic testing.

Polyester Fiber Tip Swabs:

The head material of the polyester fiber swab is made of polyester long fiber winding, which was first introduced into the field of medical testing by DuPont. Polyester fibres are proven for microbial collection, rapid diagnostics, and PCR testing.

Polyester swabs have a high release rate but are more expensive than cotton and rayon swabs.

Foam tip swab:

Swabs made from medical-grade polyurethane are an excellent material for diagnostics, especially cell sampling. The swab tip of this swab is usually manufactured as a sheet with a surface hole count of 100ppi (holes per inch).

This material has good absorption of hydrophilic substances and poor absorption of hydrophobic substances. Used in some scenarios that require resistance to chemical corrosion. Also used for DNA and microbial sampling.

Flocked Swabs:

Flocking technology was first developed for cosmetic and industrial production. (Learn more)

After the flocking process was introduced into swab production. It replaced the traditional swab head, and the swab head was brought to a new level.

vtm swab

Due to the flocking process and the multi-branched polyester fibre material used, the flocked swabs have a very high absorption and release rate and are proven to be equally efficient for molecular sampling and absorption. Designated by some institutions for nucleic acid sampling as well as some research areas for genomic analysis.

The evolution of swabs is not limited to changes in materials. New demands in the fields of nursing, testing, and scientific research make swabs continue to evolve in multiple dimensions. The swab also not only acts as an applicator, but also acts as some transport medium.

Precautions include the following:

① Do not drink water before the throat swab test, at least 30 minutes in advance, because drinking water before the test will dilute the virus attached to the pharynx, especially drinking hot water will inhibit the activity of the virus.

In order to improve the accuracy of throat swab nucleic acid detection, do not drink water 15 to 30 minutes before the test to ensure that the throat swab has high accuracy.

②. For patients with good throat exposure, it is not recommended to take too long “ah~” sounds to reduce the risk of occupational exposure to the sampler.

③ To prevent vomiting, do not eat within two hours before the throat swab test.

④. Do not smoke, drink, or chew gum within half an hour before the throat swab test.

During the throat flocked swab sampling, the patient may have clinical symptoms such as nausea or nasopharyngeal discomfort, but the symptoms can subside quickly, so the patient should not be nervous and cooperate actively during the examination. At the same time, the subjects should not smoke, drink, or chew gum within half an hour before the sample collection.

If it is because of the throat swab the child, the parents must soothe the child’s emotions, communicate with the child patiently, and try not to move the child’s head as much as possible.
