Covid-19: Antigen Test Self-Test Swabs Must Be Sterilized?

Posted on 2022年4月15日2022年4月15日 by Dr. Lee

Covid-19 antigen test self-test swabs must be sterilized?

New crown antigen test self-test sampling swabs must be sterilized? Alcohol disinfection is required before “non-sterile sterilization”?

Yesterday, a colleague looked at the record, it was about the swab used for the self-testing agent for the covid-19 antigen.

One user found that the swabs were non-sterile flocked swab during use, while some communities received sterilized cotton swabs.

Therefore, it is recommended to sterilize the flocked swab with 75% alcohol before using it.

Experts and industry insiders say such concerns are unnecessary as long as qualified products from formal channels are used.

If citizens receive swabs that are suspected to be damaged or contaminated, please discard them directly according to relevant requirements.

Is it risky to use “non-sterile” and “unsterilized” sampling swabs?

Sterile flocked swabs specimen collection

Specifically, there are two main problems that netizens worry about:

First, they are worried that the sampling swabs will be “bacteria”, which will affect the results of antigen testing.

Such as “false positives” And so on;

The second is to worry about the “bacteria” of the sampling flocked swab.

During the sampling process, the “bacteria” will be brought into the human body, affecting health.

75% alcohol can indeed disinfect cotton swabs, but a flocked swab with 75% alcohol may denature the scraped viral proteins!

The antigen is no longer that antigen, so it may lead to missed detection!

You must know that the antigen test “looks” for the antibodies produced by the new coronavirus infected person.

The display window of the reagent strip contains a protein that can recognize the antibody, like a dam, which intercepts the colloidal gold combined with the virus antibody, which is displayed in the display window. is red.

Therefore, even if the sampling swab contains “bacteria”, the kit will “ignore” it and focus on “finding” the antibodies produced by the new coronavirus infected person.

Since the kit is not interfered with by “bacteria”, it will not affect the results of antigen detection.

For some people who think that “bacteria” sampling swabs will affect human health, experts say that this may be due to a lack of understanding of “sterile” products.

Sterile ones are the best.

Flocked Nasopharyngeal Swab Suppliers and Manufacturers

However, the use of sterile flocked swabs is not mandatory, and the use of non-sterile ones will not affect the detection effect.

For the EU CE self-test, it must be equipped with a sterile CE certified swab.

Non-sterile flocked swabs also have requirements for the number of colonies.

Non-sterile swabs are also sold in the EU (probably for professional use).

A group of friends also said: “I would rather not sterilize it. As it is now, if the epoxy desorption time is not enough, it will be sold. It is better not to sterilize it. Anyway, the oral and nasopharynx is not a sterile environment, so what are you afraid of?”

The expert replied: “Swabs are generally sterilized by irradiation, and less sterilized by ethylene oxide (EO). Even if sterilized by EO, they are packaged in dialysis paper. The general standard for ethylene oxide analysis is 14 days. If the heat is accelerated, it will usually be out in 3 days. Counting the storage and logistics time.

It is basically enough for 14 days, and it is safe for the testers.”

In summary:

The European self-test product is equipped with a sterilized swab, which seems to be a product below the European standard.

At the same time, non-sterile swabs can also be used, but they must meet quality inspection standards, such as colony count.

Finally, remind everyone, do not to use alcohol to disinfect swabs, which may cause missed inspections! Of course, the outer package of the reagent can be sterilized if it is conditional!

Viral Transport Medium With Swab

Posted on 2022年4月14日2022年4月14日 by Dr. Lee

Viral transport medium with swab

The COVID-19 outbreak is expected to have a significant impact on the tedious market for swabs and virus transport media owing to the increasing patient demand for infection diagnosis.

Flocked Swab and viral transport media are expected to grow due to intensive testing of COVID-19 in research institutions and laboratories.

Rising research and development activities to produce COVID-19 vaccines are expected to drive market growth during the pandemic.

The rising number of COVID-19 cases in the global population is expected to drive market growth.

The need to develop vaccines and early diagnostics to treat infections is expected to boost the market growth.

Manufacturing of Viral Transport Medium

Virus sampling tubes are medical device products. The virus sampling tube consists of a sampling flocking swab, virus transport medium and outer packaging. Since there is no unified national standard or industry standard, the products of various manufacturers vary greatly.

CellMedical manufactures viral transport media (VTM) following WHO and CDC recommendations, with or without swabs.

Flocked swab+tube with Viral transport medium

1. Sampling swab:

Virus sample collection flocked swab

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

　　Synthetic fibres such as PE synthetic fibers, polyester fibres, polypropylene fibers, and rayon fibres should be used for the manufacture of sampling swab tips.

　　(1) Natural fibers such as cotton are not recommended

　　Because the fiber of cotton has strong adsorption of protein, it is not easy to be eluted into the subsequent preservation solution;

　　(2) Nylon fibers are also not recommended

　　Because nylon fibers (similar to toothbrush heads) have poor water absorption, the sampling volume is insufficient and the detection rate is affected.

　(3) Do not use calcium alginate sponges or wooden stick swabs (including bamboo sticks) for the head of the sampling swab.

　　Because the broken wooden sticks or bamboo sticks containing calcium alginate and wooden components will also adsorb proteins after being soaked in the preservation solution, and even have an inhibitory effect on the subsequent PCR reaction.

Features of CellMedical Flocked Swabs:

1. Has extraordinary adsorption energy.

2. It has a release rate of more than 95% for the collected specimens, thus ensuring a high degree of reliability of the results;

3. There is a unique breakable design on the plastic rod, which is convenient for specimen transportation;

4. Sterilized by ethylene oxide or irradiation, individually packaged;

Nasopharyngeal and oropharyngeal swabs. learn more

2. Virus preservation solution (virus transport medium): There are mainly two kinds of virus preservation solutions widely used in the market, one is a virus maintenance solution improved based on the transport medium, and the other is an improved nucleic acid extraction lysate. Preservation solution.

3. Virus sampling tube: The material of the storage tube should be selected carefully. Some data suggest that polypropylene (Polypropylene) is related to the adsorption of nucleic acids, especially at high tension ion concentration, polyethylene plastic (Polyethylene) than polypropylene (Polypropylene) Easier to grab 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 and contaminating when the swab is broken.

Virus Sampling Tube

4. Water for production of preservation solution: Ultrapure water used for the production of preservation solution should be filtered by an ultrafiltration membrane with a molecular weight of 13,000 to ensure the removal of biologically derived polymer impurities, such as RNase, DNase and endotoxin, and ordinary purification is not recommended. water or distilled water.

About the use of virus sampling tubes

Sampling using virus sampling tubes is mainly divided into oropharyngeal sampling and nasopharyngeal sampling:

1. Oropharyngeal swab sampling:

first press the tongue with a tongue depressor, then insert the head of the sampling swab into the throat to wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall, and wipe the posterior pharyngeal wall with mild force, avoiding touching the tongue department.

2. Nasopharyngeal swab sampling:

measure the distance from the tip of the nose to the earlobe with a swab and mark it with your fingers, insert the sampling swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be inserted at least half the length from the earlobe to the tip of the nose. Leave the swab in the nose for 15-30 seconds, swirl gently 3-5 times, and withdraw the swab.

It is not difficult to see from the method of use, whether it is an oropharyngeal swab or a nasopharyngeal swab, sampling is a technical task, which is difficult and easy to contaminate. The quality of the collected samples is directly related to the subsequent testing. If the viral load of the collected samples Low, easy to cause false negatives, difficult to diagnose.

Most of the samples recommended by the kits currently on the market are oropharyngeal swabs or nasopharyngeal swabs and bronchoalveolar lavage fluid. This can greatly reduce the difficulty of the samplers’ work. After all, it is not difficult to collect venous blood samples, and like the detection of hepatitis C RNA, about 5 ml of EDTA anticoagulated blood samples are separated into plasma, and the extracted and purified RNA can fully meet the needs of PCR detection.

Preservation solution features:

Our independent research and development and production, unique cell preservation technology, can be stored at room temperature for more than 3 years after sampling! No need to refrigerate, store and transport at room temperature.

To save RNA/DNA:
Used to store total RNA and DNA, including viral RNA and DNA, at room temperature.

Sample Type:
Used to collect a variety of sample types, including nose, mouth, throat, and skin samples.

Flocked Swab

Nylon flocked swab

Made of nylon fibre flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner.

Increasing the efficiency of collection and release of cellular and fluid samples.

So that there is no absorption hole in the entire collection area of the swab.

The collected sample does not disperse and remains in the fibre, facilitating faster and more efficient elution.

Traditional spun cotton swabs cannot completely collect and elute the sample, while flocked swabs can elute more than 95 per cent of the sample collected.

So the use of flocked swabs has great advantages for a variety of sample collection applications.

Because most of the testing tools used for nucleic acid testing are disposable sampling swabs, we usually see more nasal swabs and throat swabs.

Improve analytical sensitivity, no sample residue, and speed up sample processing.

PS stickers come off easily. Suitable for cervical, nasopharyngeal, oral, forensic collection systems and DNA collection, etc. Individually packaged.

Flocked swabs are biocompatible and ideal for PCR work.

PCR is compatible, free of RNase and DNase, so the new flocked swabs are ideal and a good choice for scientists working with PCR technology.

Flocked swab sampling is more comfortable and easier to use;

CellMedical’s flocked swabs use the existing technology “spraying technology”, which is to vertically attach millions of nylon fibres to the head of the medical swab shaft through electrostatic charges in the flocking hair.

Flocked Nasopharyngeal Swab Suppliers and Manufacturers

The vertical nylon fibres resemble a soft brush.

During sampling, the user will have no foreign body sensation.

In addition, different parts have different breaking points of the flocking swabs used, and the thickness of the swab rod is also different.

So there is a big difference in softness.

For example, for nasal swabs, the upper end of the swab rod is thin and soft, and the breaking point is also relatively back.

What is A Covid-19 NP Swab?

Posted on 2022年4月12日2022年4月12日 by Dr. Lee

The COVID-19 Swab test is an important part of the anti-epidemic work, and it is extremely important to standardize the operation of sampling techniques.

All sampling operations must be standardized. In order to provide a strong guarantee for the accurate reporting of subsequent nucleic acid testing.

Nasopharyngeal (NP) swabs are the primary sample type for respiratory molecular pathogen testing.

During the 2019 novel coronavirus infectious disease (COVID) pandemic, NP swabs became central to the detection of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2).

Unfortunately, NP swab collection can be very uncomfortable for some patients.

Because when collecting nasal swabs, a relatively long flocked swab, is directly inserted into the nasal cavity of the person being collected.

However, nasal swabs will not cause pain if the operator is appropriate, but some people with sensitive noses or diseases may experience mild discomfort.

Np swab covid test meaning?

Np swab is the nasopharyngeal swab test, which refers to a relatively conventional method for detecting viruses.

Nasal swab testing mainly involves inserting a relatively long sterile flocked swab into the patient’s nasal cavity.

It was then collecting secretions from the nasopharynx through the nasal cavity.

And then testing these secretions in various aspects, such as bacterial culture And drug sensitivity test to determine the source of infection and the type of microorganisms.

Symptomatic treatment according to the test results, and a drug sensitivity test can also be used to determine which drug is more sensitive.

Use the more sensitive drug for treatment.

What should medical staff pay attention to when collecting nasopharyngeal swabs?

All healthcare professionals performing nasopharyngeal swab tests must wear the recommended personal protective equipment (PPE), which should include N95 masks, disposable caps, goggles, protective clothing, latex gloves, and shoe covers.

Nasopharyngeal flocked swabs: performed with the patient sitting upright with the head in an upright position.

What is A Covid-19 NP Swab?

The subject needs to tilt his head back.

Nasopharyngeal swabs are not along the nostrils, but perpendicular to the face, entering from the nasal passages.

When collecting, do not enter violently when encountering resistance or the subject feels obvious pain.

When taking nasopharyngeal sampling, the operator can stand behind the subject and does not need to look directly at the nasal cavity.

In addition, there is basically no gag reflex, the tolerance is good, and the risk of exposure is relatively low.

After sampling, the individual tested may have a sneeze reflex, immediately use an elbow or a tissue.

A small number of subjects may have a little nosebleed after sampling, which can usually be stopped on their own.

When taking a nasopharyngeal swab, it can stay in the nasopharynx for a longer time in order to obtain a more adequate sample.

Studies have shown that the positive rate of nasal swab samples is higher than that of throat swab samples, that is, the efficiency of nasal swabs for virus swab detection is higher than that of throat swabs.

What can a nasopharyngeal swab detect?

Used for nasopharyngeal sampling for respiratory viruses such as influenza, swine flu, bird flu, and hand, foot and mouth.

A nasopharyngeal culture

The reasons for false negatives

1. Patient: The virus content may be too low. The nucleic acid swab detection reagent has certain requirements for the virus presence in the infected person. If the virus is too low, existing methods may not detect it.

The onset of new coronary pneumonia patients will go through a process from asymptomatic after infection, to mild symptoms, to severe symptoms.

2. Collection of specimens: false negatives cannot be completely avoided.

Many experts have concluded from practical work that the positive rate of sputum and bronchoalveolar lavage fluid samples collected from the lower respiratory tract is higher than that of oro-nasopharyngeal swabs from the upper respiratory tract; the positive rate of nasopharyngeal swab samples is higher than the Oropharyngeal swab.

Improper collection site, for example, when collecting oropharyngeal swabs, the depth of the collection is not enough;

Nasopharyngeal swabs are not enough deep into the nasal cavity, etc., and most of the collected cells may not contain viruses, which may cause false negatives.

3. Detection reagents: At present, the quality of the reagents on the market may vary.

4. In addition to the test reagents themselves, laboratory specifications will also have an important impact on the test results. Specimen transportation and storage conditions, standardized operations in clinical laboratories, result interpretation and quality control are all key factors to ensure the accuracy and reliability of test results.

Prevent false negatives

Incorrectly performed nasopharyngeal swabs may lead to a greater likelihood of patients receiving false-negative test results.

False-negative results are an important issue to address, as these results can cause patients who are positive for some diseases to unknowingly transmit highly contagious diseases, especially COVID-19, too many others.

Therefore, adequate training of testers on how to perform nasopharyngeal swab tests reliably is critical. Use high-quality detection reagents. learn more.

Covid Swab Test To Your Baby

Posted on 2022年4月11日2022年4月12日 by Dr. Lee

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

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

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.

CellMedical Specimen Collection Swabs manufacturers

Determine the age of the child, the button clips are on the appropriate upper lube), make sure the swab is not too deep;
To collect samples, the observer (observer) should only be at the necessary distance.
Know the internal program processor of the laboratory. Or use a cotton swab to test the transport tube.
Send the sample to the lab for immediate testing.
In the laboratory, when taking clinical samples, wear protective gloves and protective equipment related to general precautions.
The conditions, timing, and volume of samples collected for clinical research are variables for obtaining reliable results. Follow recommended sample collection guidelines.
CellMedical swabs should only be used by personnel.

Swab manufacturers & suppliers

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

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

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

Posted on 2022年4月3日2022年4月3日 by Dr. Lee

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:

Remove the nasal swab.
Measure about 2 cm with a swab and mark with your finger.
Insert a cotton swab about 2 cm (about 3/4 inch) into one nostril.
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. .
Using the same swab, repeat for the other nostril.
Place the swab back into the virus delivery medium.
Place the end of the swab firmly so that the tip of the swab is in contact with the wet swab.
Tighten the cap of the tube, mark it well, and put it in a plastic bag and seal it.

Covid-19 antigen test self-test swabs must be sterilized?

Is it risky to use “non-sterile” and “unsterilized” sampling swabs?

First, they are worried that the sampling swabs will be “bacteria”, which will affect the results of antigen testing.

The second is to worry about the “bacteria” of the sampling flocked swab.

Sterile ones are the best.
