Respiratory Swab Collection

1. Importance of Flocked Nasopharyngeal Swabs in Pertussis Detection

Early diagnosis of pertussis relies heavily on respiratory specimen collection and testing, with flocked nasal swabs playing an indispensable role in the sampling process.

1.1 Precise Sampling Ensures Accurate Detection

Bordetella pertussis colonizes the ciliated epithelial cells of the respiratory tract, making the collection of nasopharyngeal secretions essential for obtaining reliable samples.

Nasopharyngeal sampling sticks, made with specialized materials, feature a flocked design that significantly improves secretion collection, especially those containing Bordetella pertussis.

Compared to traditional throat swabs, nasopharyngeal collection tools conform better to the nasopharyngeal region, achieving higher positive isolation rates and improving sample quality. This reduces detection errors and provides stable results for subsequent PCR testing or bacterial culture.

1.2 Compatible with Multiple Detection Methods

Collected samples can be used for various detection techniques, including:

  • PCR Testing: Fast and sensitive, providing results within hours and suitable for early-stage diagnosis.
  • Bacterial Culture: Though time-consuming, it offers detailed analysis of bacterial characteristics, aiding further treatment.

The combination of these methods enables a comprehensive assessment of pertussis progression, laying a foundation for precise treatment.

COVID-19: Main Symptoms

Posted on by

The three main symptoms of “new crown”: are fatigue, brain fog and muscle pain, the specific manifestations vary from person to person. Other more common persistent symptoms include shortness of breath, chills, body aches, headache, joint pain, chest pain, cough, and persistent loss of taste or smell.

 Forgetfulness, anxiety: “I feel useless”

Many people with long-term symptoms report cognitive impairment or memory loss that affects their ability to make everyday decisions, speak, follow directions and drive, and impair their quality of life.

Xiao Liu (pseudonym) works in British media. Three years ago, he suffered from depression. He largely recovered before contracting Covid-19 in November 2021 and has stopped taking antidepressants. But after she contracted Covid-19, the depression returned. The doctor assessed and judged that one of the symptoms of the new crown-brain fog persisted.

“After I got the new crown, I felt that I was ‘brainless’, I didn’t want to do anything, and I was extremely anxious.”

It starts with cold-like symptoms, headache, cough, fever, and loss of taste and smell. There are also chest tightness, shortness of breath, fatigue, insomnia, loss of appetite, forgetfulness, inability to concentrate, unresponsiveness, anxiety, etc.

“The overall condition is not good, and the weight has lost four kilograms”

After Xiao Liu fell ill, the children became sensible. I get up every morning looking for a school uniform to wear, and my 11-year-old will scramble eggs, eat breakfast, and go to school alone. My brother was hungry at night, so he cooked instant noodles and ate them together.

Xiao Liu remembers coughing for three weeks, being bedridden for a month, and then taking a long sick leave of more than three months.

“I couldn’t get out of bed to cook at all. The children ate takeaways every day, and my mouth ulcers had developed for a long time. Fortunately, some friends helped us and often brought us home-cooked food. At that time, the volunteers in the community even gave me anti-inflammatory drugs. Depression. Come to my house and make sure I take it on time. My family doctor advised me to call my psychiatrist again.”

“The biggest motivator for me was the several home visits from the social worker in charge of child welfare. The kind help made me extremely anxious and insomniac, and I felt like an incompetent mother who couldn’t do even the most basic things to take care of her children.” Covid has cost me! It’s unacceptable to me.”

“Regular doctor consultations and cordial greetings from unit leaders also made me feel like I was a burden. I didn’t want to be sick all the time. Everyday burnout and bedridden made me feel like I was useless.” “

For a long time, Xiao Liu felt that he had Alzheimer’s disease. Can’t remember anything, looking for something every day. It takes a few repetitions to understand what the doctor says. Sometimes after calling in the morning to confirm, call in the afternoon to ask.

“Sometimes I don’t know if I have taken medicine or not. Once I enter the kitchen, I forget what I am doing. I look at the pills with a water glass and ask myself if I just took the medicine or not?”

Because of the confusion caused by many small things, Xiao Liu deeply doubts his ability to do things. She feels that she must first learn to forgive herself and accept herself who is often tired and forgetful now.

Xiao Liu said that now he wants to make himself happier and more optimistic by doing one small thing every day. Doctors want to taper off antidepressants over a year.

Fatigue: “Three hours of sleep when I get back from the store”

Severe fatigue is by far the most common symptom of COVID-19. Other symptoms include muscle pain, hearing and vision problems, headaches, loss of taste and smell, damage to the heart, lungs, kidneys, and intestines, diarrhea, and mental health problems, including depression, anxiety and distraction, and stupor.

Before being diagnosed with “coronavirus”, she had been suffering from persistent fatigue, fever, and loss of smell and taste for months, for which she consulted several doctors of different specialties.

At first, my temperature rose slightly, I felt dizzy, and then my throat started to hurt. A day later, my fever reached 38.5°C. 

Later, I went for a checkup and received treatment. 

After three weeks of conventional viral infection treatment, tachycardia was found, while fatigue symptoms did not decrease.

Frequent blood tests, blood pressure measurements, and lung monitoring are performed. After taking antibiotics and vitamins for three weeks, the treatment failed, and he underwent ENT, pulmonology, cardiology, virology, rheumatology and immunology tests. Found chronic sinusitis, and heart adhesion, but not sure if it is caused by the new crown, it was still there before.

After a month, blood cell counts stabilized, but mental and physical fatigue and fever persisted.

For seven months, I was unable to concentrate, disoriented, felt hot, shivering, tired, didn’t know when it was going to pass, and felt scared every day.

At the doctor’s advice, make a “resurrection” plan, start walking, but take breaks from time to time, sleep at least three hours after going to the store or spend an hour in front of the computer.

 Cognitive Function and Brain Fog: “IQ Decreases…”

“I’m not back to normal, from a cognitive standpoint, I’m not back to where I was before the coronavirus, in terms of focus, agility, flexibility… a year and a half later, I feel like I’ve only lost 30-40 %”. she says. % has been restored. I’m not the same as before, my IQ has dropped. “

“After a year and a half, after a lot of hard work, a lot of self-discipline, and all things considered, my condition has improved. I have anxiety (cognition) and I won’t fully recover, but I’m slowly accepting the possibility.”

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

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

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

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

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

COVID-19: Will The Pandemic End in 2022?

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

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

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

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

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

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

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

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

Flocked Sterile Swabs

Sterile Flocked Swab

Oropharyngeal swab

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

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

Nasopharyngeal swab

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

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

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

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

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

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

How to overcome the discomfort of throat swab

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

Recommended to relax before collecting specimens.

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

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

What is viral transport medium ?

Posted on by

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.

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.

Covid VTM Swab Test

The virus sampling swab set is a virus sampling and transfer product for virus nucleic acid detection.

It generally consists of a sampling swab, a sampling tube and a virus preservation solution.

For the nasopharyngeal and oropharyngeal new coronavirus sampling swab sets.

Also known as virus transport medium (Viral Transport Medium), referred to as VTM.

According to the composition and function of virus preservation solution, it includes non-inactivated and inactivated types.

The purpose of the single-use virus sampling tube:

Viral Transport Medium With Swab

Viral Transport Medium With Swab

The single-use virus transport medium with tube is our company’s best-selling star product. It is suitable for the collection and transfer storage of various influenza viruses, clinical new coronaviruses, influenza,  measles and other virus samples. nucleic acid extraction and later virus isolation.

It is also suitable for collecting and transporting specimens such as Chlamydia, Mycoplasma, and Ureaplasma urealyticum.

Specimens are usually collected from the oral cavity, throat, nasopharynx, anus, and other human body parts.

Combination features of our single-use virus sampling tube kits (vtm swab kits):

Disposable virus sampling tubes include sampling swabs and sampling tubes (vtm kits).

Flocked Nasopharyngeal Meaning Swab Test Sample Collection Vtm Kit

Test Sample Collection Vtm Kit

1. Sampling flocking swab: our company uses a nylon flocking swab (vtm swab). Because nylon flocking has no toxic effect on microorganisms and viruses and does not contain RNase and DNase.

It can maximize the collection and release of virus samples and ensure the accuracy of PCR test results.

The flocked swab rod: ABS material, with a unique breakpoint design.

Convenient to put into the sampling tube without contamination.

2. Virus sampling tube: The tube body and tube cover are made of polypropylene, which will not deform at high temperature and high pressure (121°C, 15min).  And will not become brittle at low temperatures (-196°C).

Resistant to static extrusion and dynamic impact.

The bottom cone design is resistant to centrifugation and shock.

They are packed with a transport medium (inactivated type, preserved type) for the release and preservation of samples to prevent leakage.

The sampling tube has built-in magnetic beads, which are convenient for elution and facilitate the release of more viruses into the virus transport medium.

Before the higher positive rate of PCR detection, the storage solution in the virus sampling tube was Hank’s solution.

Now, the virus sampling tube preservation solution has been upgraded to CellMedical virus preservation solution.

(that is, UTM, recommended by the World Health Organization and the National Influenza Center of China.)

Based on hank’s solution, BSA, HEPES, amino acids, glycerin and other ingredients. A high PCR test is positive.

Virus preservation solution includes non-inactivated virus transport medium and inactivated virus

In the non-inactivated COVID-19 sampling swab set, the components of the virus preservation solution usually include nutrients (such as salts, proteins, glucose), bacteriostatic agents, buffers, phenol red indicator, etc. required for the survival of the virus.

This virus preservation solution can maintain the activity of the virus to the greatest extent.

Not only for virus detection but also for virus culture and isolation.

In the inactivated new coronavirus sampling swab kit, the components of the virus preservation solution usually include buffers, virus lysing agents (usually guanidines), surfactants, etc.

This preservation solution can directly lyse the virus to release nucleic acid, which is convenient for subsequent nucleic acid detection.

How To Properly Administer A Covid Swab Test To Your Baby

COVID-19 still plagues all parts of the world, and it will become more serious in spring, so there are still many people who need to do nucleic acid tests.

Do many parents have many questions about nucleic acid testing for children, especially babies, such as how to do nucleic acid testing for 10-month-old babies?

A little girl is being swab tested for nucleic acid

A little girl is being swab tested for nucleic acid

How do nucleic acid swabs test for children?

The nucleic acid test method for 10-month-old infants and adults is the same.

The method of throat swab is used. The throat is sampled.

When sampling, you only need to tilt your head slightly, open your mouth wide, and wait for the medical staff to use a flocked swab.

The swab stick can be sampled.

You may feel a little nauseous during sampling, but it is not particularly uncomfortable in general.

This kind of discomfort is acceptable to basic children, and the sampling process is relatively fast, so parents don’t need to worry too much.

Of course, it is not ruled out that some children do not cooperate. In this case, older children can communicate well, explain the situation, and parents can show the children how to carry out nucleic acid testing; if it is a child who is too young to communicate, then you have to grab it forcibly for sampling.

It should be noted that before going to the hospital for examination, you must make an appointment first, otherwise, it will be a waste of time.

Since different hospitals or testing centres generally have different methods for ordering nucleic acid testing.

It is important to understand the hospital nucleic acid testing process before officially performing nucleic acid testing.

In addition, it is not recommended to eat about two hours before the nucleic acid test.

If you are nauseous during the sampling, you may vomit or spit milk, but this is rare.

Baby swab tests

Baby swab tests

 

  • You bring your child’s safety to a stable place (a blanket on the floor, a changing table, another adult’s arms).
  • Consider wrapping them in a warm blanket to relax and prevent their elbows from helping you.
  • Show them a pacifier (make sure you can adjust their nostrils) if the pacifier will soothe them.

In general, bring the kids to a convenient place where you know them best.

As an adult helper, you can take the kids on their laps.

We recommend keeping your back against the patient’s reason and facing toward the person holding the flocked swab.

Then you can start!

 

The nucleic acid test method for children is the same as that for adults.

The throat swab is to extract the secretions of the respiratory tract for testing.

Because the baby has a problem with cooperation, it is best not to feed the child 2 hours before the nucleic acid test.

During the nucleic acid detection process, children may not cooperate.

If they have just finished eating food, they will vomit, which will affect the nucleic acid detection results.

Nucleic acid testing uses a long throat swab to smear on the back wall of the pharynx.

The medical staff are more skilled and will not cause much impact on the child.

Instructions for use, specimen collection

Note Sterile gloves, protective clothing and goggles should be worn when collecting and handling microbial specimens;

Open the peel bag and remove the flocked swab.
