What is Swab Test

Posted on by

If you are considering whether you should get a COVID-19 swab test, symptomatic or asymptomatic.

Under normal circumstances, the virus is spread through the air to our nose or mouth.

We have to wear masks to prevent the infection of the virus from the source.

Assuming we are unfortunate enough to carry the new crown, the virus will enter the throat through the nose and mouth, and then enter the alveoli through the trachea and bronchi.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs. The sample is collected from your nasal cavity or mouth when the nurse’s sister gives you a nucleic acid test.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs, which are the samples taken by the nurse sister from your nasal cavity or oral cavity when you are doing nucleic acid testing.

Due to the convenient operation and high accuracy, these two methods have been widely used. Now I will tell you about nasopharyngeal swabs and oropharyngeal swabs in detail.

What is a nasal swab test?

Specimen Collection Swab

Specimen Collection Swab

Our respiratory tract is divided into the upper respiratory tract and lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. In medicine, the cricoid cartilage is used as the boundary to distinguish.

The nasopharyngeal swab test is a medical test method. A medical cotton swab is used to wipe a little secretion from the nasopharynx of the human body, placing it in a special incubator, and placing it in a temperature-controlled device for cultivation. Can understand the patient’s condition, oral mucosa and pharyngeal infection.

Compared with oropharyngeal swabs, nasopharyngeal swab sampling has the following advantages:

1. When collecting oropharyngeal swab samples, the sampler can see the location of the pharynx to be sampled, and the irritation to the oropharyngeal mucosa may cause the sampled to cough, nausea, and even vomit.

2. When collecting nasopharyngeal flocked swab samples, the irritation to the nasopharyngeal mucosa is relatively small if the operation is standardized.

3. But the sampler cannot see the location of the pharynx for sampling, and mainly relies on the resistance felt by the hand to complete the sampling, so the technical requirements are higher, and the tools used are also more complicated.

4. It can stay in the pharynx for a longer time to obtain a sufficient amount of specimens, which is why the positive rate of the swabs reported in the literature is higher than that of oropharyngeal swabs.

5. The patient’s tolerance is good. After the skilled operation, sampling can be performed without anesthesia, but surface anesthesia and contraction of the nasal mucosa can be performed first for beginners.

Analyzing material effectively starts with collecting samples with the right tools, whether it’s collecting samples from the body to aid in medical diagnosis, identifying potentially harmful pathogens from the environment.

Or collecting samples from crime scenes to aid in investigations.

However, it is also important to ensure that contaminants do not come into contact with the sample as it travels to the laboratory. Given the plethora of options available for each of these missions, choosing the right collection and transport vehicle can be overwhelming. This is where a specimen collection kit can prove invaluable.

Features:

1. Safety: Sampling and virus inactivation are carried out simultaneously, which greatly reduces the operator’s infection risk;
2. Stability: keep the sample stable, avoid nucleic acid degradation, and ensure the accuracy of the test results;

Instructions:

What is the Specimen Collection Kit?

As pointed out over, example collection packages have shown very usefully in securing examples for analysis in a large range of clinical, environmental and research study applications.

Nasopharyngeal samples collected by swabbing the upper retronasal vocal cords can supply analysis confirmation for a series of viral as well as bacterial infections, consisting of influenza, COVID-19, enterovirus D68, as well as other respiratory system conditions.
Fecal samples can be gathered by anal or fecal swabs as well as can aid clinicians detect a series of intestinal microbial infections.
A vaginal swab example can help determine the visibility of Group B Streptococcus or Streptococcus agalactiae, a type of microorganisms found in the digestive system and also birth canals of a quarter of pregnant ladies, to name a few conditions.
Food sampling is not just important for recognizing the potential presence of foodborne pathogens but is a crucial step in maintaining conformity with FDA food security requirements.

How to choose the right specimen collection kit?

It is necessary to discover a sampling collection set created for your particular end-use. This consists of using the flocked swab that best matches your sampling collection needs. As an example, foam swabs might use elution characteristics best matched for environmental and also food sampling, while polyester or crowded swabs may supply a combination of collection attributes and also person comfort far better fit for medical usage.

Nonetheless, it is not constantly necessary to utilize a sample collection package created for usage with the example cpu’s very own brand name of the fluid transfer system. Validation examinations can aid clinicians, food mill and also other samplers, and also labs recognize precise and also affordable sample collection kits. Verifying shipping systems from several suppliers has come to be a common practice in research laboratories around the globe, not just to ensure sustainable supply, but likewise to compare item top quality and expense.

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.

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.

Nylon Flocked Swabs

During an outbreak, everyone should be familiar with sampling swabs. When doing nucleic acid, touching the nose and throat is directly touching the sampling site of human organs, that is, directly touching our human organs. Therefore, the material of the sampling head will affect our comfort and is closely related to the subsequent detection.

On This Page

What is a Nylon flocked swab?

About sampling swab material.

What are the types of swab tests?

Nylon flock swab

Sampling swabs should be polyester, nylon and other non-cotton, non-calcium alginate swabs, and the handle should be non-wood. The breakpoint is located about 3cm from the top of the swab head, which is easy to break.

NASAL FLOCKED SWAB

NASAL FLOCKED SWAB

Moreover, the experimental analysis shows that the extraction efficiency of nylon flocked swabs is the highest. In contrast, the recovery efficiency of nylon flocking swabs is also higher than that of other material swabs.

Nylon fibre flocking technology. The front end is coated with vertically fixed nylon short fibers, so that the entire sampling area of ​​the sampling swab has no absorption holes, and the sampling sample will not be scattered in the fibers, which is conducive to faster and more efficient sampling!

Compared with traditional winding swabs, nylon flocking swabs collect and release 3 times the number of samples, do not damage cell samples, ensure the survival rate of cell samples, do not leave fatty acids, do not affect the test and detection results, not to mention Said to cause harm to the human body.

What materials cannot be used for sampling swabs?

As we all know, the materials of medical swabs have always attracted much attention. After all, medical swabs come into direct contact with the skin. People who touch the skin can first touch alcohol for disinfection, that’s fine, but what about those who have direct contact with organs? For example, the throat swab we are most familiar with during the epidemic.

The throat swab is in direct contact with the sampling site, and the material of the sampling head is closely related to subsequent testing. The sampling swab head should be made of nylon flocked swabs or rayon, and calcium alginate sponges or wooden stick swabs (including bamboo sticks) should not be used.

Cotton products should not be used for the swab head, because the cotton fiber has strong adsorption to protein and is not easy to clean into the subsequent storage solution; wooden.

What are the types of swab tests?

There are two different types of COVID tests – Swab tests and antibody tests.

1. Swab tests can show if you have an active coronavirus infection and should take steps to isolate or isolate yourself from others. There are currently two types of diagnostic tests – molecular (RT-PCR) tests that detect the genetic material of the virus, and antigenic tests that detect specific proteins on the surface of the virus. Samples are usually collected with a nasal or throat swab, or saliva spits into a test tube.

2. Antibody tests look for antibodies that the immune system produces in response to a threat, such as a specific virus. Antibodies can help fight infection. Antibodies can take days or weeks to develop after infection and may remain in the blood for several weeks after recovery.

Therefore, antibody tests should not be used to diagnose active coronavirus infection.

Right now, researchers don’t know whether the presence of antibodies means you’ll be immune to the coronavirus in the future. While there is a lot of uncertainty surrounding this new virus, the widespread availability of antibody testing and clinical follow-up over time also has the potential to provide the medical community with more information about whether and how long a person has recovered from the virus of people have a reduced risk of infection if they are re-exposed to the virus.
