Ethylene Oxide Covid Test Sterile Swab

Posted on 2022年3月17日2022年3月30日 by Dr. Lee

EO sterilization refers to ethylene oxide sterilization.

Ethylene oxide (EO) is a highly efficient and broad-spectrum gaseous disinfectant.

It is by far the only most reliable and widely used sterilization method recognized worldwide.

The nasal sampling flocked swabs included in the COVID-19 test kits are sterilized by EO or gamma-ray sterilization.

Rest assured, the swab is safe to use. Including ethane is a gas use commonly used to sterilize different types of medical equipment, flocked swabs for test kits.

The time period for the entire process includes multiple heights and set-up phases, including post-swab removal of sterilized equipment to control ethane treatment.

Allows monitoring of residues in contact with humans (EO amount has been according to ISO 10939-7:2008) ).

Ethylene Oxide Covid Test Sterile flocked Swab Principle

What is the principle of ethylene oxide sterilization (EO sterilization)?

Ethylene oxide, also known as ethylene oxide, has the molecular formula C2H4O.

The boiling point is 10.4°C, it is soluble in water, and the explosion limit in air is 3% to 100% (volume).

Ethylene oxide is a highly volatile, explosive, flammable and toxic substance with ether smell when volatilized. It is a spectral sterilant.

Ethylene oxide can effectively kill various microorganisms, including bacterial propagules, spores, viruses and fungal spores, and is a broad-spectrum high-efficiency sterilant.

Ethylene oxide molecule can produce alkylation reaction with a carboxyl group, amino group, sulfhydryl hydrogen group and hydrogen group on gene proteins necessary for metabolism in bacterial cells.

Instead of the unstable hydrogen atoms on the above groups, form a hydroxyethyl group.

The rooting compound, because this compound destroys the necessary reactive groups in the important metabolic reactions of microorganisms, affects the action of bacterial enzymes, and causes the death of microorganisms.

Nasal swabs included in COVID-19 inspections are EO sterilized.

I heard that ethylene oxide sterilant is toxic and carcinogenic, but covid sterile swaps are all sterilized with ethylene oxide.

Is it safe for us to use a covid swab?

Is the risk of cancer caused by directly entering the respiratory tract greater?

The words “Clean and Sterile EO” on the product packaging of sterile flocked swabs. At this point there’s a crowd that’s saying “

Specimen Collection Swab Ethylene Oxide In Swabs

It’s completely dry here.

There’s no result. But once you put it in a person’s nose, it’s wet. Once you inhale it, it’s going to kill us. It’s really killing people.”

While it’s safe to say that direct exposure to ethylene oxide is actually linked to cancer (here), that doesn’t suggest that swabs sterilized with ethylene oxide definitely cause cancer cells.

Ethylene oxide is a valuable disinfecting gas because it is very good at inactivating bacteria.

It is used in factories in a very tightly controlled method to ensure that people working in manufacturing plants are not put at risk.

It is a common chemical used to sterilize clinical tools and leave a minimal amount of product behind.

In conclusion, EO is a gas commonly used to sterilize clinical equipment such as COVID-19 nasal swab tests.

Ethylene oxide (ethylene oxide) is a highly efficient and broad-spectrum gaseous disinfectant.

It is by far the only most reliable and widely used sterilization method recognized worldwide.

Although EO is carcinogenic, the use of this gas is safely regulated and has actually been used for decades.

Sterilization procedures are regulated to ensure minimal EO residues on medical tools.

What is Viral Transport Media

Posted on 2022年3月14日2022年3月30日 by Dr. Lee

What is VTM?

VTM is the acronym for Viral Transport Media, which contains nutrients that carry the virus and keep it active so that the sample can reach the laboratory for testing.

VTM virus preservation solution is suitable for the collection, preservation and transportation of common virus samples.

Such as new coronavirus, influenza virus, hand, foot and mouth virus. It can collect throat swabs, nasal swabs or tissue samples from specific parts.

And the stored samples can be used for subsequent nucleic acid extraction or Purification and other clinical experiments.

Virus Transport Medium (VTM) Definition

The virus transport medium sampling tube is a complete set of centrifuge tubes for sampling and transporting viruses.

What is Viral Transport Media

Such as new coronavirus, influenza virus, hand, foot and mouth virus in the microbial sampling transport tube.

Also known as the specimen transport tube. commoditized products.

A nutrient is used to carry and maintain the viability of test specimens (viruses) for the identification and further processing of samples in laboratories.

Viral Transmission Media Principles (VTM)

Since there is no cellular structure. Viruses cannot replicate themselves, but instead, invade genes into host cells and replicate new viruses with the help of the latter’s replication system.

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 will be put into the transportation medium for storage and transportation.

Transportation medium composition and inspection principle:

1. The combination of various antibiotics has broad-spectrum antibacterial and antifungal effects.

2. As a protein stabilizer, bovine serum albumin (BSA) can form a protective film on the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus

3. The neutral environment constructed by Hank’s buffer helps to increase the survival time and infection stability of the virus.

4. Phenol red is an acid-base indicator, the discoloration area is 6.6 (yellow)-8.0 (red), and it is red at 7.2-7.4.

Vtm Kit

The most stable pH value of the viral outer layer protein is 7.2-7.4, which is also the pH value range of Hank’s buffer. If contaminating molds or bacteria are not inhibited by antibiotics, they can multiply, releasing carbon dioxide and lowering the pH.

At this time, the appearance of the sampling solution will change from red to yellow.

Notes:

To produce an isotonic solution containing proteins to protect viral structures, antibiotics to control microbial contamination, and one or more buffers to control pH.
Use the concept of assays such as nucleic acid amplification assays (NaAt) to prepare viral delivery media while preventing samples such as drying.

Composition of viral transport media (VTM Kits)

There are mainly the following parts:

1. Sampling swab with disposable sterile plastic rod/rayon head;

2. Sterile sampling tube containing 3ml of virus maintenance solution;

In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc.

Viral delivery media typically have protective protein components, antimicrobial agents to prevent the potential for contamination, and buffers to maintain the pH of the solution.

Some VTMs also have additional ions and minerals that help keep such samples viable.

How to use Virus Transfer Media?

Liquid transfer media are primarily used to transfer the swab or material from the collection swab into the media.

It facilitates the collection and transport of samples in areas where it is not available.

Precautions for use:

1. Before sampling, indicate the sample information on the label of the cryopreservation tube;

2. According to different experimental purposes, use sampling swabs to sample at the corresponding parts (the most commonly used are nasopharyngeal swabs, pharyngeal swabs are the oral swabs in the product);

3. Immediately after sampling, put the swab into the sampling tube containing the virus transport medium, break it at the breaking point, and tighten the tube cover;

4. The specific sampling methods are as follows:

a) Nasal swab: Gently insert the flocked swab head into the nasal palate, stay for a while and then slowly turn to exit. Swab the other nostril with another swab, immerse the swab head in the sampling solution, break it at the breaking point, and discard it.

b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a flocked swab, and also immerse the swab head in the sampling solution and discard it.

Why Choose Anal Swab Covid Tests

A friendly netizen said,

“The anal test first asks you to take off your pants and lie on the bed,

The paramedic then stabs (anus) twice with an anal swab,

shallow once deep

In addition to the endless shyness in the whole process,

Nothing else feels like it! ”

A shy handsome man

Xiaolee will tell you why you need to do anal swabs.

Currently screening for COVID-19,

Mainly use an oropharyngeal swab and nasopharyngeal swab nucleic acid detection,

Because of its convenience and speed, it is suitable for large-scale screening;

Nasopharyngeal Swab Sample

However, some asymptomatic or mildly infected people,

The disease recovered quickly after infection,

Nucleic acids in the respiratory tract and pharynx are undetectable within 3-5 days.

longer duration of nucleic acid-positive stool or anal swab,

Therefore, adding anal swabs can improve the detection rate,

Effectively reduce the probability of false negatives,

Reduce missed diagnoses!

One of the anal swab samplings poses

Friends who have done nucleic acid swab tests have experience,

In previous tests,

The most uncomfortable part should be the part of the nasopharyngeal swab,

To poke the nose is to poke deep into the soul.

According to the description of the anal swab recipient,

“The whole process was lying in bed and the medical staff helped.

Insert the tip of the sampling cotton swab into the anus and turn it a few times.

Twice in total, each for about 10 seconds.

Although a little surprised and a little embarrassed,

But understandable and bearable,

After all, this rule is for everyone’s sake. ”

Many Chinese friends who have returned to China for quarantine

I have also experienced the subtle taste of it.

Covid Sampling Flocked Swab

Flocked refers to the process of applying multiple lengths of fibers to the surface of the adhesive coating.

It is basically the same as the cotton swab except for the material.

It can also be said that the flocking adheres to the head of the flocked swab. It is a flocking swab, but it is different from cotton swabs in that it is a disposable sampling swab composed of nylon short fiber fluff head + ABS plastic rod.

How does a Covid Mouth Swab Test work?

Posted on 2021年12月24日2022年3月22日 by Dr. Lee

How does a Covid Mouth Swab Test work?

I went for a swab test for the new coronavirus the day before yesterday, and the result came out yesterday and it was negative. Some friends asked me, is the throat swab test painful? How to do it? What are the types of COVID-19 tests? What COVID-19 test is more accurate? Today, Dr Lee came to give everyone a popular science.

You can use a variety of tests to determine whether you have COVID-19. Some tests are collected by mouth swabs, and some are collected by nasal swabs or saliva. In the experiment, an oral flocked swab was used to collect samples from the oral cavity for oral inspection. This is different from a saliva test, which spits out saliva into a small container.

What is a mouth swab? Painful?

The COVID-19 test is the most important way to diagnose the new coronavirus. Nucleic acid is the genetic material RNA of the new coronavirus. The nucleic acid test is to check a certain segment of RNA. If it is positive, it means that you are infected with the new coronavirus.
According to different sampling sites, nucleic acid detection can be divided into many types, such as throat swabs, anal swabs, tracheal secretions, alveolar lavage fluid, and so on.
Among them, throat swabs are the most commonly used, and oropharyngeal or nasopharyngeal secretions are taken for laboratory tests.

Oropharyngeal swab, the inspection process is very fast, no more than 10 seconds, only needs to open the mouth, and the staff uses a cotton swab to take a sample in the oropharynx.

Covid Mouth Swab Test work

When sampling, there will be a slight pain, and when the throat is stimulated, there will be a feeling of vomiting.

But the feeling is not strong, and it will be fine for a while.

According to British colleagues, the nasopharyngeal swab is more uncomfortable, and the pain will be greater because the nasopharyngeal swab needs to be completely pricked into the nose. Learn more about nasal swabs Please click here

How to interpret the results of the Oral swab test?

Nucleic acid(COVID-19) testing usually produces results within 24 hours. If you check today, the results will be known the next day. The results are nothing more than two cases, negative or positive.

Does negative mean there is no infection?

It is not 100% certain, because nucleic acid testing has a certain probability of false negatives. For example, in the early stage of the disease, the virus content is very low, and it may not be detected, or the sampling is not taken properly, and the sensitivity of the detection reagents, operation Whether it is standardized or not, etc., are affected by many factors.

How to do a mouth swab COVID-19 test

How to use mouth swab

There are different ways to do a COVID-19 mouth swab:

1. The patient needs to sit with his head back, open the mouth, and then remove the nasal cavity and the secretions on the oral surface.
2. The collector uses a special tongue depressor to fix the patient’s tongue, and then cross the throat with the collecting tool, and the tonsils directly to the position where the specimen is taken.
3. After repeated wiping of the collection table, mucosal cells can be directly extracted.
4. Take out the collected throat swabs. Be careful not to touch the oral mucosa, tongue and saliva secreted by the oral cavity during this process to prevent inaccurate test results.
5. Put the extracted throat swab into a special device and transport it to the laboratory for examination.

You may need to take specific steps before the test so that the results are as accurate as possible. If you need to book an appointment, ask if there’s anything you should avoid on the day of your test. Some types of tests that use saliva require that you don’t eat, drink, smoke, brush your teeth, or chew gum 30 minutes before the test (FDA, 2020).

What are the types of COVID-19 tests?

In the UK, when diagnosing COVID-19, there are usually two main types of tests:

Molecular biology tests, such as PCR (polymerase chain reaction), are used to find viral genetic material.

Look for the antigen detection of the virus shell.

Either test can be done with a nasal swab or a mouth swab. Saliva can also be used for PCR detection (FDA, 2021a). Although saliva and oral swab tests may sound the same thing, they are actually slightly different. The saliva test requires you to spit into the tube, while the oral swab test is to wipe a sample in the mouth with a cotton swab.

Nasal mucosal secretions follow the same rules, but the difference is that you or a health care professional collect the sample from your nose instead of your mouth.

Another type of test is antibody testing (also called serological testing). These two data can’t tell you whether you are infected now but can tell you whether you have been infected before or if you have been vaccinated before. Antibody testing usually requires a blood sample.

What COVID-19 test is more accurate?

How to interpret the swab test results

Nucleic acid testing usually produces results within 24 hours. If you check today, the results will be known the next day. The results are nothing more than two cases, negative or positive.

Does negative mean there is no infection?

It is not 100% certain, because nucleic acid testing has a certain probability of false negatives.

For example, in the early stage of the disease, the virus content is very low, and it may not be detected, or the sampling is not taken properly, and the sensitivity of the detection reagents, operation Whether it is standardized or not, etc., are affected by many factors.

With the continuous optimization of detection methods and the continuous updating of reagents, the sensitivity of detection is now higher, and the probability of false negatives is lower than before.

If it is negative, there is a high probability that it has not been infected with the new coronavirus.

For some high-risk groups, close contacts, and suspected clinically highly suspected cases, one negative may not be enough, and two, three, or even multiple tests may be required.

Notice

Even if you have been tested before, COVID-19 testing is difficult to cope with. But the test should be able to relieve stress and not cause stress.
In any case, the knowledge of COVID detection technology is constantly changing. If you want to know if you want to be tested and how it works, we will help you at any time. Here is some information about oral swab COVID testing and other information to determine whether COVID-19 is COVID-19, you need to know.

1. Sampling is more comfortable and convenient.

Our company uses the existing technology “spraying technology” to vertically attach millions of nylon flocked micro fibers to the head of medical grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of soft brush. Using this soft brush in the sampling process makes the user feel no foreign matter. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

For example, nasal swab, its upper end of the rod is thinner and softer, and its breaking point is longer.

Sterile Flocked Nylon Swab with 80mm Breakpoint.

2. Flocking swab samples release more.

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample remains on the surface to make elution easier. In the traditional cotton swab, most of the samples collected are still captured in the fiber matrix of the head, which is not easy to release or the release amount is small. Flocked swabs have been shown to release up to 95% of the sample, compared with 25% for standard fiber pointed swabs. If the sample size is particularly small, the use of flocking swabs is particularly important.

3. Flocking swab has biocompatibility and is an ideal choice for PCR.

In order to limit the damage to the sample and improve the accuracy of detection, disposable sampling swab is made of better quality nylon flocking swab.

This makes flocking swabs an ideal choice for PCR Swab Test. Therefore, for scientists using PCR technology, the new flocking swab is PCR compatible and does not contain RNase and DNase.

How are flocked swabs used for specimen collection swab?

Our flocked swabs feature perpendicular nylon fibers that optimize specimencollection and elution into transport media. The swabs also feature a moldedbreakpoint that allows you to safely and easily break off the swabstick, and severalbreakpoint options are available for different tubes.

Oral Swab Stick

Posted on 2021年9月28日2022年3月22日 by Dr. Lee

Oral Swab Stick-Oropharyngeal sampling swab.

COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.

Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.

Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.

The results of COVID-19 nucleic acid test are also useful.

What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?

Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.

For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.

What is the difference between Oral Swab Stick and Nasal Swab?

Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.

What are the advantages of nasopharyngeal swabs?

It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.

Can a positive oral swab stick confirm COVID-19?

The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.

After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.

Patients with positive nucleic acid test of new crown must be isolated and treated.

Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.

How to sample oropharyngeal swabs?

First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.

The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.

According to the personal experience of colleagues: slightly disgusting, but completely acceptable

The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.
