Covid Swab Test To Your Baby

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.

Nasopharyngeal swabs are suitable for collecting and transporting virus specimens such as covid-19, clinical influenza, avian influenza, hand, foot and mouth disease, and measles, as well as specimens of chlamydia and mycoplasma.

In order to respond to this round of the epidemic, stop the spread of the virus and reduce the risk of infection.

At present, we have successively carried out multiple rounds of swab testing for the new coronavirus.

Why are oropharyngeal swabs and nasopharyngeal swabs performed in covid swab testing?

covid flocked swab

covid flocked swab

Nasopharyngeal swab refers to the collection of secretions from the throat or nose of a patient with a specialized sterile flocked swab.

We generally use nasopharyngeal swabs to detect viral nucleic acids, viral antigens, and bacterial cultures.

The collection site of the oropharyngeal swab should be the pharynx and tonsils.

The basic steps of collecting the pharyngeal swab are to tilt the patient’s head back, open the mouth wide, and remove the secretions on the surface of the nasal cavity.

The sampler fixed the tongue with a tongue depressor and used polyester or calcium alginate test paper to cross the base of the tongue.

Wiped the posterior pharyngeal wall and the lateral wall of the tonsillar recess 3-to 5 times to collect mucosal cells.

Remove the swab gently, avoiding contact with the tongue, uvula, oral mucosa, and saliva, and insert the swab back into the sampling device or a suitable transport device.

Nasopharynx swab vs oropharyngeal swab

Nasopharynx swab vs oropharyngeal swab

The main difference between the two lies in the sampling method and sampling location.

The detection rate and accuracy of nasopharyngeal swabs are higher than those of oropharyngeal swabs.

Still, nasopharyngeal swabs are more complicated and difficult to operate, and people with nasal diseases。

Such as rhinitis and nasal polyps will not easily adapt, Bleeding may occur during the collection process, so the collection speed is slow.

Compared with nasopharyngeal swabs, oropharyngeal swabs are fast, simple and easy to collect.

And the detection rate can meet the requirements.

Therefore, oropharyngeal swabs are often used in large-scale screening.

For key groups or middle- and high-risk groups.

Required to collect nasopharyngeal swabs, or even stool and blood samples.

In addition to nasopharyngeal swabs and oropharyngeal swabs.

There are also detection methods such as serum, anal swabs, deep cough sputum, nasopharyngeal or respiratory tract extracts, and bronchial lavage fluid.

In general, the method of sample collection will be determined according to different populations and different needs.

How to Perform Mrsa Nasal Swab

How to Perform Mrsa Nasal Swab

Methicillin-resistant Staphylococcus aureus (MRSA) is increasingly rampant, and its infection spreads almost all over the world.

Together with AIDS and hepatitis B, it has become the three most difficult infectious diseases in the world.

How to prevent and control MRSA has become a problem that we cannot ignore.

The long-term treatment of MRSA infection, in addition to the direct economic burden on patients, will also generate some indirect costs, such as isolation, disinfection and so on.

n response to the prevalence of MRSA, we should propose strict detection and control measures.

MRSA screening is an important part of this.

Medical swabs are one of CellMedical’s specialties. Our goal is to ensure that our swabs give end users what they really need so they can always perform at the highest level.

In this article, we review what MRSA is, why using a nasal swab is the most effective way to test for MRSA, and how to perform a nasal swab test for MRSA.

What is MRSA?

MRSA, known as Methicillin-Resistant Staphylococcus aureus.

A highly drug-resistant strain of bacteria found mainly in people with long-term chronic diseases.

It is naturally resistant to penicillin and cephalosporin antibiotics, and also has varying degrees of resistance to commonly used erythromycin, etimicin, ofloxacin and other drugs.

Mainly seen in patients with bloodstream infection, lung infection and other site infections.

If the treatment effect is not good after a variety of antibiotic anti-infection treatment, it is necessary to consider whether there is mrsa infection. This bacterium is only effective against antibiotics such as vancomycin, teicoplanin, and linezolid.

MRSA is contagious through person-to-person contact and when a contaminated person touches an object or surface and leaves behind germs that can spread.

About 126,000 people are hospitalized and 19,000 die from the bacteria each year.

MRSA Nasal Swab

A nationwide cross-sectional study of MRSA screening in more than 10,000 patients showed that screening sites included the nose, throat, underarm, perineum, and wound or implant sites. Nasal swabs identified only 66% of MRSA carriers, and further swab testing could increase the detection rate.

Nasal and perineal swabs were identified in 82% of patients, with the axilla being the least useful site for carrier identification (8% detection rate).

Standard screening methods should include at least two swabs (nasal swab plus perineal or pharyngeal swab).

According to the American Society for Microbiology, nasal swabs have a higher detection rate of MRSA than traditional swabs. Flocked swabs provide better sample collection because their brush-like tips release more target cells and retain more liquid sample than foam swabs.

Our flocked-Swab sterile swabs are designed for the collection and transport of clinically significant bacteria.

With molded breakpoints, sampling is fast, safe and convenient.

How to use MRSA Swab?

Once a sampling swab and transfer medium, such as CellMedical’s flocked-Swab media transfer system, has been selected, testers should wash their hands and wear clean gloves.

The process is as follows:

  1. Remove the nasal swab.
  2. Measure about 2 cm with a swab and mark with your finger.
  3. Insert a cotton swab about 2 cm (about 3/4 inch) into one nostril.
  4. Insert the swab into the nostril perpendicular to the nose (face), rotate the swab against the anterior nasal mucosa for 3 seconds, then gently rotate 3 times. .
  5. Using the same swab, repeat for the other nostril.
  6. Place the swab back into the virus delivery medium.
  7. Place the end of the swab firmly so that the tip of the swab is in contact with the wet swab.
  8. Tighten the cap of the tube, mark it well, and put it in a plastic bag and seal it.

Swab Specimen Collection

Swab Specimen Collection

A throat swab refers to the use of a sterile medical long flocked swab to dip a small number of secretions from the pharynx of the subject.

And then carry out the detection of respiratory viruses, bacteria and other pathogenic microorganisms.

The collection site of the throat swab is the pharynx and tonsils of the subject, and precautions should be taken when collecting.

Swab Specimen Collection details are as follows:

Swab Specimen Collection

Swab Specimen Collection

1. Drinking water before the oropharyngeal test strip 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 the nucleic acid detection of throat swabs, required 15-30 minutes before the test. Do not drink water to ensure the high accuracy of throat swab nucleic acid detection;

2. We do not recommend that patients with well-exposed larynx keep hair in order to reduce the occupational exposure risk of the sampler;

3. To prevent vomiting, avoid eating two hours before collecting throat swab specimens;

4. Do not smoke, drink, or chew gum half an hour before sample collection.

In addition, the basic steps of throat swab collection are:

1. Ask the patient to sit down, tilt their head back, open their mouth wide, and take out the surface secretions in the nasal cavity;

2. The sampler fixes the tongue with a tongue depressor, and uses a cotton swab to cross the base of the tongue to the posterior pharyngeal wall and the lateral wall of the tonsillar recess, etc.;

3. Wipe 3-5 times repeatedly to collect mucosal cells;

4. Gently remove the test strip, avoid touching the tongue, uvula, oral mucosa and saliva;

5. Insert the test strip back into the sampling device or a suitable transfer device.

There are various Specimen Collection swabs available on the market.

Which one is the best one to choose?

CellMedical recommends “synthetic flocked swabs“.

Compared with traditional wound swabs (although they are also made of synthetic fibres), the amount of samples collected and released by this swab is 3 times higher, and it does not damage the cell samples, which can ensure the survival rate of the cell samples and has no fatty acid residues. Contains substances that inactivate certain viruses and inhibit PCR detection.

Nasal Gene Sampling Flocked Swab Oral Gene Sampling Flocked Swab

Although the positive rate of the new coronavirus RNA test is directly related to the quality of the reagent itself, the quality control of the whole process is more critical, which includes sample collection, transportation, storage, testing and all consumables used for testing. As long as one step is not well controlled, it is difficult to achieve the quality (detection rate) of the reagent itself.

How To Do Covid Swab

How To Do Covid Swab

Covid Swab testing include nasopharyngeal swabs and oropharyngeal swabs.

A sample taken by a doctor from a patient’s nasal cavity via a nasopharyngeal swab to test for Covid-19.

The oropharynx refers to the detection of secretions mainly from the soft palate, tonsils and other parts of the patient.

We need to pay attention to protection for nucleic acid testing.

The advantage of nasopharyngeal swabs over oropharyngeal swabs is that they are easy to operate.

The operator can stand behind the patient’s side, with only the nostrils exposed, without looking directly into the patient’s mouth.

There is basically no gag reflex, and the exposure risk of the sampler is lower than that of nasopharyngeal swabs.

How to do a covid nasopharyngeal swab without pain?

Since the flocked swab sampling is from the lower nasal passage all the way to the bottom of the nasopharynx.

It is more painful to perform, but in this process, the more nervous and conflicted, the more uncomfortable it will be during sampling.

Therefore, when doing a nasal swab, recommended to relax a little, then tilt your head back, keep still.

And use your nose to inhale and exhale through your mouth.

The collector will make this process quick and generally not too painful.

Does nasopharyngeal swab bleeding affect test results?

It will not affect.

Bleeding when taking a nasal swab is due to the rupture of capillaries in the nasal mucosa when the specimen is taken.

However, under normal circumstances, as long as the secretions from the nasopharynx are collected.

A small amount of bleeding will generally not affect the test results. have an impact.

However, if the secretions from the nasopharynx are not collected during the bleeding.

It is necessary to resample the nasal cavity on the other side after stopping the bleeding by resting.

Therefore, when doing a nasal swab, it is recommended to relax and listen to the collector.

So that sampling can be completed quickly.

Which is more accurate, nasal swab or throat swab?

It has been reported in the literature that when taking samples for SARS-CoV-2 virus nucleic acid detection, the results obtained by simultaneously sampling throat swabs and nasal swabs are generally equivalent.

Therefore, for a nasopharyngeal swab and pharyngeal swab, there is no special regulation on which one to do. It is recommended that those who need to do sampling can choose according to their own conditions. If they can tolerate pharyngeal swab collection, they can do pharyngeal sampling. After the nasal swab was collected, a nasal sampling was performed.

Can nasopharyngeal swab be made by themselves?

Not.

Since the nasal swab test needs to insert the swab deep into the nasal cavity to collect samples, there may be adverse reactions such as pain, gag reflex, tearing, and even nosebleeds during the process, causing physical discomfort and psychological discomfort to the collected person. The sense of resistance will be very strong, so there are highly professional requirements for the sampling personnel, and they cannot be done by themselves.

What Is Specimen Collection ?

What Is Specimen Collection ?

The surge of covid-19 has seriously affected our life and production.

With the efforts of most scientific researchers, the test of this virus came out.

Collection methods of common virological test specimens.

Nasal Swab Virus Sampling Kits

Nasal Swab Virus Sampling Kits

1. Draw 5 ml of blood for serological examination without anticoagulation

2. Extract cerebrospinal fluid through an aseptic procedure, place it in a sterile test tube, and immediately send it for examination in an ice bath.

3. Take a cervical or vaginal swab to take the secretions from the lesion site.

If there is no lesion site, clean the mucus of the cervical mouth, stick the swab about 1 cm into the cervix and hold it for more than 5 seconds to take it out. And put the swab in the transport solution on the ice at 4 °C. 

4. Fecal specimens Take 2g~4g of stool specimens in a sterile container, add 8ml~10ml of transport fluid, and send them for inspection immediately.

5. Gargle solution: The patient can get it by gagling with sterile normal saline several times. After mixing the same amount with the transport solution, send it for inspection immediately.

6. Throat swab: Use a tongue depressor to fully expose the throat to avoid saliva contamination. Use a swabened moist with normal saline to collect specimens on the surface of the throat, and place them in transport fluid for inspection.

7. Nasopharyngeal swab: Take nasopharyngeal secretions for bacterial culture and drug sensitivity test.

7. Urethral swabs and urine specimens.  The tester inserts the urethral swab 4 cm into the urethra and rotates it gently 2 to 3 times to obtain more epithelial cells. Then take it out and send it to the transport fluid for inspection.

The classification of new coronavirus nucleic acid samples includes nasopharyngeal swabs, oropharyngeal swabs and anal swabs. Different specimens use different methods for specimen collection.

What is a Specimen Collection Kit?

 Viral Transport Kit: for collecting, handling, and transporting specimens suspected of VIRUS.

Generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for sampling in different parts. people.

Virus sampling tube: When collecting samples, routine samples could not be detected by PCR immediately. It is generally necessary to transport the swab sample with the specimen. The virus itself dissolves rapidly in vitro, affecting subsequent experiments. For transport, viral transport medium must be added.

What is the Specimen Collection Kit used for?

How Accurate Is The Nasal Swab

 The nasopharyngeal swabbing is generally the preferred method of specimen collection for COVID-19 testing.

1. Disposable virus sampling tube is used for monitoring and sampling infectious pathogenic microorganisms in the disease control part and clinical part. Suitable for sampling influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.). Hand, foot and mouth disease virus and other types of viruses.

It can also be used for sampling other respiratory diseases such as Mycoplasma and Chlamydia. COVID-19.

2. For transporting nasopharyngeal swab samples or site-specific scheduled samples from the sampling point to a testing laboratory for extraction and testing by polymerase chain reaction.

3. For the preservation of nasopharyngeal swab samples or samples arranged at specific sites for necessary cell culture.

Swab in specimen collection

1. Swabs with polyester fibre, polyester or rayon head and plastic or aluminium handle: suitable for the collection of virological test specimens. The collection of virological test specimens should not use swabs with wooden handles.
2. Cotton swabs: It is suitable for the collection of vaginal, cervical and urethral specimens for the mycoplasma test. It is not suitable for the collection of bacteria (especially fastidious bacteria) and chlamydia test specimens.
3. Polyester swabs and nylon swabs: suitable for a sampling of virus and bacterial specimens.
4. Flocked swab: It is made of nylon fiber through proprietary spray technology, and is suitable for respiratory virus sampling and fungal culture specimen sampling.
5. Calcium alginate swab: suitable for the collection of nasopharyngeal swabs for Chlamydia and Bordetella pertussis.

However, it is not suitable for the sampling of lipid-enveloped virus and cell culture. It is not suitable for the sampling of Neisseria gonorrhoeae and Ureaplasma urealyticum.

What Is Virus Transport Medium

What Is Virus Transport Medium

The virus transport medium is novel and unfamiliar to many small partners, but it is of great significance for the detection of various viruses.

The new crown virus has tortured human beings enough.

In the face of a large number of COVID-19 patients, some places are still rising.

Therefore, as soon as there are new additions, many places will focus on the new crown nucleic acid detection.

The virus preservation solution plays a very important role.

Virus Transport Medium with Specimen collection swab

Virus Transport Medium with Specimen collection swab

At present, the nucleic acid detection of the new coronavirus is mainly the detection of viral nucleic acid.

Virus transmission medium is a cell preservation liquid, which protects the virus to be detected by immersing the flocked swab head with the virus sample into the transport tube.

It is mainly suitable for the new coronavirus, Collection, preservation and transportation of common virus samples such as the influenza virus.

To collect throat swabs, nasal swab or tissue samples from specific parts.

The stored samples: for subsequent nucleic acid detection or clinical experiments such as virus culture.

Since the virus is a parasitic organism, it cannot survive outside the body after sampling.

If it cannot be detected in time, it needs to be placed in a virus preservation solution for preservation. (Virus Transport Medium)

In order to protect the safety of the virus detection environment and the safety of the detection personnel, inactivated virus preservation solution is actually a better choice!

FLOCKED SWAB

FLOCKED SWAB

For different detection purposes, we need to use different virus preservation solutions for preservation.

The two widely used preservation solutions have their own characteristics.

In order to meet different detection requirements and different experimental conditions for virus detection, it is necessary to use different preservation solutions.

The inactivated virus preservation solution can inactivate the virus.

How to detect it after inactivation?

The purpose of our use of inactivated preservation solution is to lyse nucleic acids, release nucleic acids and then carry out nucleic acid detection by subsequent real-time fluorescent RT-PCR.

Doctors use inactivated virus transport media to determine whether the sample contains virus characteristic nucleic acid, that is, whether we carry the virus.

Inactivated virus transport medium:

A virus lysis type preservation solution improved by nucleic acid extraction lysis solution.

Effectively prevent the secondary infection of the operator, but it also contains inhibitors, which can protect the viral nucleic acid from being degraded.

This enables subsequent detection by NT-PCR.

Moreover, stored at room temperature for a relatively long time, which saves the cost of virus sample storage and transportation.

Non-inactivated virus transport medium:

A virus maintenance liquid type preservation solution improved on the basis of the transport medium.

It maintains the activity of the virus in vitro and the integrity of antigens and nucleic acids.

The protective viral protein shell makes it difficult to decompose and maintains the originality of the virus sample to a great extent.

For nucleic acid extraction and detection, the experimenters also use the transport medium for virus culture and isolation and maintain the activity of virus samples.

In addition to nucleic acid extraction and detection, the inspector also uses this preservation solution for virus culture, isolation and antigen detection.

Nasal Swab Test

Nasal Swab Test

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

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab.

I see a lot of people on the Internet saying that the nasal swab is very painful, sour and straight to the sky, this is because your posture is not correct! !!

How Accurate Is The Nasal Swab

Nasopharyngeal swabbing is generally the preferred method of specimen collection for COVID-19 testing.

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab.

Their purpose is to let the flocked swab sample from the inner wall of the throat.

Nasal swabs are not meant to poke your heavenly lid!

Nasopharyngeal culture

A nasopharyngeal culture is a test that examines a sample of secretions from the uppermost part of the throat, behind the nose, to detect organisms that may cause disease.

Nasopharyngeal Swab Pcr Test

Nasopharyngeal Swab Pcr Test

Therefore, you should tilt your head as far back as possible to allow the cotton swab to go in horizontally.

That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds.

But if you keep your head upright, then the flocked swab can only be poked from bottom to top, which will definitely pierce the upper part of the nasal cavity.

That position is very sensitive, and it will hurt very much when pierced.

And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

One sentence summary: Tilt your head back and let the flocked swab go in and out horizontally all the way.

Why you should take the swab test.

This test identifies viruses and bacteria that cause upper respiratory symptoms.

These include:

Bordetella pertussis, the bacterium that causes whooping cough Meningococcus meningitidis.

The bacterium that causes meningococcal meningitis is Staphylococcus aureus, the bacterium that causes staph infections Methicillin-resistant Staphylococcus aureus virus infection.

For example, influenza or respiratory syncytial virus cultures can be used to help determine which antibiotic is appropriate to treat infections caused by bacteria.

Normal Results The presence of common organisms in the nasopharynx is normal.

What an abnormal result means The presence of any disease-causing viruses, bacteria or fungi means that these organisms may be causing your infection.

Sometimes, organisms like Staphylococcus aureus can exist without causing disease.

The test can help identify resistant strains of the organism (methicillin-resistant Staphylococcus aureus, or MRSA) so that people can be quarantined if necessary.

Risks There are no risks to this test

Viral transport media for COVID-19 testing

Viral transport media for COVID-19 testing

At present, medical technology needs to promote positive energy!

The current epidemic has come and gone.

In particular, important medical materials such as disposable virus sampling tubes (virus transport media) play a key role.

At present, the quality of the products of various manufacturers on the market is also uneven, and there is also a risk of affecting the accuracy of the experimental results.

Make products with a realistic and rigorous scientific attitude;

Let the front-line medical staff have no worries, and provide them with a steady stream of “cannonballs”.

Below we will define the virus delivery medium and explain typical components and options for use.

What is a virus transport medium?

UTM Tube with NP Flocked Flexible Swab

UTM Tube with NP Flocked Flexible Swab

1. Virus sampling tube;

Some data suggest that polypropylene (Polypropylene) is related to the adsorption of nucleic acids, especially at high tension ion concentration, polyethylene plastic (Polyethylene) is easier than polypropylene (Polypropylene) to grasp DNA/ RNA.

In addition, when using breakable swabs, the storage tube should try to choose a container with a height of more than 8 cm to prevent the contents from splashing.

Some tubes may be formulated to contain buffered proteins and antibiotics to inhibit the growth of potentially contaminating bacteria and fungi.

2. Virus Transport Media;

VTM consists of Hanks Balanced Salt, Foetal Bovine Product, anti-bacterial prescription antibiotics, anti-fungal anti-biotics as well as Phenol Red as an indication for real-time surveillance of pH security of the service.

3. Collection of flocked swab;

The sampling swab directly contacts the sampling site, and the material of the sampling head is closely related to the subsequent detection.

Sampling swab tips should be made of Polyester (PE) synthetic fibers or Rayon (man-made fibers).

Prohibit calcium alginate sponges or wooden stick swabs (including bamboo sticks).

For example, the material of the swab tip cannot be cotton.

Products, because cotton fibers have strong adsorption of protein.

It is not easy to be eluted into the subsequent preservation solution.

 Our flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability.

Viral transport media applications

The virus sampling tube is a complete set of centrifuge tubes for sampling and transporting viruses such as influenza virus, hand, foot and mouth virus, covid test, etc. in the microbial sampling transport tube, also known as the specimen transport tube.

In the current epidemic, virus sampling is also an important part. Generally, viruses exist in large quantities in the nasopharynx of the human body.

The pharyngeal tester collects virus samples from the nasopharynx and puts them in a virus sampling tube.
