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.

Ethylene Oxide Covid Test

Ethylene Oxide Covid Test Sterile Swab

Posted on by

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

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.

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

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;

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!

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.

This article
To talk to you in detail
Covid nucleic acid test!

But in the face of the “nucleic acid swab test”
This unfamiliar and familiar word
Do you have many questions?

Image source network

Do you want to do a nucleic acid test when you go back?

Will it be difficult to make an appointment for nucleic acid testing?

How long does it take to get the results of a nucleic acid test at the hospital?

Should I Swab My Throat or Nose for Rapid COVID-19 Tests?

To answer your questions.
Today.
I’m going to tell you.
Those things about nucleic acid testing.

01. What is nucleic acid detection?

At present, nucleic acid detection is the main method for laboratory diagnosis to determine whether a patient is infected with the new coronavirus. It can achieve early detection, early diagnosis, and early treatment. Real-time fluorescent PCR can be used to detect throat swabs, sputum or blood samples. to covid nucleic acid, or detected by viral next-generation gene sequencing.

simply put

Nucleic acid testing is done by

After collecting human secretions

Tested by the instrument

to see if we have the new coronavirus in our body

If so, the test result is positive

On the contrary, if it doesn’t, it’s negative.

02. How to test the COVID swab?

“Sir, oropharyngeal swab, nasopharyngeal swab, and anal swab, which one to choose?”

How do you do a nasopharyngeal swab?

Nasopharyngeal swabs must be performed with the patient sitting upright with the head in an upright position, as this allows for easy visualization and access to the nasal floor perpendicular to the central axis of the patient’s face.

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Insert the swab into the patient’s nose and align it parallel to the nose and the base of the septum. As long as there is no obstruction in the nasal cavity, the swab continues to move in this direction until it reaches the nasopharynx, at which point the tester feels resistance.

Once the swab reaches the nasopharynx, a gentle rotation and two complete 360-degree rotations are recommended to allow secretions from this area to be absorbed.

Once the swab is removed from the patient’s nose, it is immediately inserted into a viral sample containing a viral transport medium. The handle of the swab extending through the opening of the vial was broken off to allow the tube to be closed.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions
Let’s take a look at their respective advantages and disadvantages

The specific operation of the anal swab is as follows:

Soak a flocked swab in saline, insert it 2-3 cm into the anus, wipe from the folds around the anus, or rotate it gently inside the anus, and insert it into a test tube containing saline.

anal swabs

For fecal swab cultures, all of the above requires the use of sterile equipment and placing the swab in a sterile tube.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions.
Let’s take a look at their respective advantages and disadvantages.

Oropharyngeal swab: relatively simple to operate, less irritating, suitable for large-scale screening. Therefore, the nucleic acid test of oropharyngeal swabs is mainly used in the screening of new coronary pneumonia for the epidemic-related population, which is used in the routine nucleic acid test clinic of the First Affiliated Hospital of NTU.

Nasopharyngeal swab: The technical requirements are high, the human body does not feel comfortable, and the accuracy rate is higher than that of the oropharyngeal swab. However, for some asymptomatic or mildly infected people, the condition recovers quickly after infection, and the pharyngeal nucleic acid may not be detected in 3 to 5 days.

Anal swab: high accuracy, reduce missed diagnosis. The study found that the duration of nucleic acid-positive feces or anal swabs of some infected persons is longer than that of the upper respiratory tract. Therefore, anal swab tests will be carried out for key groups such as isolation points or some imported overseas.

In conclusion.
The three swabs have different lengths.
If you have to test an anal swab.
Don’t be shy.
Whatever the swab,
It is a good swab that can accurately identify the virus.

Nasopharyngeal Swab Sample (Nasal Swab)

The nasopharyngeal swab: A specimen collection tool used to collect cell samples from the nasopharynx (above the throat).

When a patient develops an upper respiratory tract infection, doctors can use the collected samples to detect it, especially when the patient still has a fever.

In the experiment, technicians can detect common sources of infection, including potential pathogens such as the new crown and swine flu.

How is the COVID-19 nasal swab test performed?

Such tests can be uncomfortable for patients, but can quickly identify serious respiratory illnesses, especially those that require isolation or infection prevention measures to protect other patients.

Doctors can use cell cultures to determine the type of current infection. Factory-produced nasopharyngeal swabs cannot use natural substances such as cotton, as they may contain some impurities that will affect the detection.

Nasopharyngeal Swab materials

The nasopharyngeal swabs produced and sold by Cell Medical Company are flocked materials. Learn more about flocked swabs.

flocked swab

flocked swab

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

In general, a caregiver can place a sealed package (safety bag) next to the patient, and the caregiver places a sample container next to the patient, which contains a culture medium that maintains cellular and microbial viability for evaluation. This is the viral transport medium.

Laboratory technicians can detect the source of infection through nasopharyngeal swabs, and they should wear gloves and masks when collecting nasopharyngeal swabs.

Face protection is an effective measure to prevent patients from contracting respiratory diseases.

Nasopharyngeal swab collection

When taking the sample, gently insert the swab into the nose by hand, pushing it all the way to the nasopharynx. Patients often experience discomfort, convulsions, or spasms; for this, they sometimes need to suppress this response by leaning their heads against a wall or pillow.

When the nasopharyngeal swab is fully in, the caregiver can briefly swirl to collect the cell mixture, remove it, and place it in the specimen collection container. (Virus sampling tube)

After the sampler obtains the sample, he should immediately send it to the laboratory for PCR testing.

Waiting or not storing at low temperature may kill microorganisms that may be present in the sample, resulting in false-negative test results.

Patients usually get results within a day or two.

Inspection is capable of scanning for many common microorganisms.

When infectious diseases appear in epidemic areas, nasopharyngeal swabs and other microorganisms can be labelled to detect new crowns, swine flu and other microorganisms.

The doctor can try the test results to guide the patient’s treatment.

They can also help epidemiologists track the movement of diseases in the community, which is very useful for controlling disease outbreaks.

What is a Medical Swab


In the COVID-19 sampling, medical flocked swabs are the most commonly used testing method.


Application: oral mucosal cells, oral microorganisms, virus sampling and transportation, DNA/RNA collection, throat sampling, cervical sampling, nasopharyngeal sampling and other fields.


In addition, we can also use medical cotton swabs for the collection and transportation of DNA for paternity testing.


As well as the collection, preservation and transportation of flu specimens.


According to the material, medical swabs can be divided into cotton swabs, foam swabs, non-woven swabs, flocked swabs and other products. Among them, the market share of cotton swabs is higher, reaching 76%.


According to the application field, medical swabs include gynecological, cervical and vagina sampling swabs; oral, nose, and pharynx sampling swabs; laboratory test sampling swabs; virus and bacteria sampling; disposable sampling swabs; sterile cell sampling And other products.


However, due to the influence of new coronary pneumonia and the popularization of nucleic acid testing, the proportion of medical swabs used for specimen sampling is increasing.


With the continuous improvement of medical conditions in developing countries around the world, the application demand for medical swabs is on the rise.


In 2020, the global medical swab market will reach 400 million U.S. dollars, with an output of about 38.4 billion pieces.


Moreover, due to the development of the world economy, the price of medical cotton swabs has shown an upward trend.

Choose the right medical swab


Swabs are one of the most commonly used disposable devices in the medical industry. But how do you know which application to choose? We have put together a brief overview on how to choose the right medical swab for your specific needs.


Cotton swab


The tip of American pharmaceutical-grade spun cotton fiber has become the standard for applicators for all applications from basic patient care to crime scene investigation.


With strong water absorption capacity, softness, low cost and safety, the performance of the cotton swab is consistent and reliable.


However, it is generally not recommended to use cotton swabs for specimen collection.


why? The characteristics of this natural material prevent the sample from being effectively released, and the naturally occurring fatty acids in this material interfere with the processes used in microbiology and DNA extraction and have proven harmful to organisms.


Rayon cotton swab


"<yoastmark


Rayon is a synthetic fiber made from wood pulp.


Although classified as synthetic fiber, it is actually a natural material.


Unlike cotton, artificial fiber removes materials that may sample or react to samples for transportation and processing during the production process, so it is usually used to sample for diagnostic tests.


Polyester fiber swab


"<yoastmark


Swab head material adopts polyester filament winding.


Polyester fiber is used for microbial collection, rapid diagnosis and PCR detection.


The polyester scraper has a higher release rate, but its cost is higher than cotton swab and rayon swab.


Foam tip swab:


Foam swab
Foam swab


The swab made of medical polyurethane is a very good diagnostic material, especially suitable for cell sampling.


The number of holes on the surface is generally 100 PPI (holes per inch).


This material has good hydrophilicity and poor absorption of hydrophobic substances.


Used in occasions where resistance to chemical corrosion is required, and it is also used for DNA and microbial sampling.


Synthetic swabs (rayon and polyester) are used to collect bacterial culture specimens, rather than cotton swabs that may contain inhibitory or toxic substances.


Flocked swab:


flocked swabs
flocked swabs


First developed flocking technology for cosmetics and industrial production.


Because of the planting process and the use of multi-head bifurcated polyester fiber materials.


The flocked swab has a very high absorption and release rate, and it is also effective for molecular sampling and absorption.


Some institutions designate to conduct research on nucleic acid sampling and certain genome analyses.


At present, the development of swabs not only reflects the changes in the materials of sampling swabs, but new demands in the fields of nursing, testing, and scientific research have led to the multi-dimensional development of swabs.

Flocked swabs for sample collection


The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod.


The brush head can be used for Virus cell collection.


It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

Why flocked swabs?


The flocking swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod. The brush head can be used for DNA collection. It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.


So that there is no absorption hole in the sampling area of the whole sampling swab.


And the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.


Traditional cotton swabs can not completely collect and elute samples, while flocking swabs can elute 95% of samples.


Therefore, the use of flocking swabs has great advantages for various sample collection applications.


Nasopharyngeal flocked swab;


Flocked swabs have some advantages;


1. Sampling is comfortable and easy to use;


Flocking swabs now basically use “spray technology”, which vertically attaches millions of nylon fibers to the head of medical ABS swab rod through the flocking process of electrostatic charge.


The function of the vertical nylon fiber is similar to that of a soft brush. The use of this soft brush in the sampling process makes the user feel free of foreign objects. 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, the nose swab is thinner and softer at the upper end of the rod, and the breaking point is longer, which fully conforms to ergonomics.


2. Flocked swab samples release more;


The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is kept on the surface to make elution easier. It is much larger than the traditional winding cotton swab. The experimental research shows that the collection and release of flocking swab can reach 95% of the sample, while the cotton swab is only about 20%.


Because most of the samples collected by the cotton swab are easy to be intercepted in the fiber matrix layer of the head during release, it is not easy to release or release a small amount.


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, while the flocking swab is PCR compatible and does not contain RNase and DNase.


Operation method of flocked nylon swab:


Take the sampling method of oropharyngeal swab as an example;


1. First, ask the patient to sit down, then let the patient tilt his head back, open his mouth, and make an “ah ~” sound.


2. The sampler fixed the patient’s tongue with a tongue depressor, and used a flocking swab to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.


3. Wipe repeatedly for 3 ~ 5 times to collect mucosal cells.


4. Slowly take the swab out of the mouth, vertically put it into the virus preservation solution, break the tail of the swab, and tighten the sampling tube to avoid leakage.


5. Send to the laboratory for testing as soon as possible.


Swab flocked matters needing attention:


1. The swab shall be placed vertically in the sampling tube, and shall not be wiped to the bottle mouth to avoid pollution.Viral Transport Medium.flocked swab copan.


2. It is best to send it or send it to the laboratory for inspection on the day of sampling.


3. Before submission for examination, it must be verified that the specimen is consistent with the submission form. The appearance of the sampling tube must clearly write the patient’s name and basic information.


4. The submitted samples must submit (or submit the electronic version in advance) screening information form, inspection form and other materials.

All about the Nasal Swab


Nasal Swab:nasopharyngeal np swab.


The specimens collected from nucleic acid samples are mainly pharyngeal swabs, which are divided into “nasopharyngeal swabs” and “oropharyngeal swabs“.


Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth, and nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.


How to do a nasopharyngeal swab?


A man was doing a nasopharyngeal swab sample
A man was doing a nasopharyngeal swab sample


Nasopharyngeal swab sampling method.


Hold a swab close to the nostril to enter, and slowly go deep along the bottom of the lower nasal tract.


Since the nasal tract is curved, do not use too much force to avoid trauma and bleeding.


When the top of the swab reaches the posterior wall of the nasopharyngeal cavity, rotate it gently for one week (stay for a moment in case of reflex cough), then slowly take out the swab and immerse the swab head into a tube containing 2 ~ 3ml virus preservation solution.


About Nasal swab sample collection.


How to take a swab sample?


Ask the patient to take off the mask and blow his nose with a paper towel to remove excess secretions from the nasal cavity. Remove the swab from the package.


Tilt the patient’s head back slightly to make the nasal passage easier to pass through. Ask the patient to close their eyes to reduce the mild discomfort of the operation.


Gently insert the swab over the bottom of the nasal canal along the nasal septum until the nasopharynx stops when resistance is felt.


Insert the cotton swab parallel to the upper jaw into the nostril.


If you feel resistance when passing, step back and try to reinsert it at another angle to bring it closer to the bottom of the nasal canal.


The depth of the swab should be equal to the distance from the nostril to the opening outside the ear.


CDC recommends placing the swab for a few seconds to absorb enough secretions, and then slowly removing it while rotating the swab.


Some organizations may also recommend rotating the cotton swab several times before taking it out.


After removal, ask the patient to put on the mask again.


Specimen processing


Open the virus transport medium and insert the swab into the collection tube.


Break the swab at the groove and discard the remaining part. Seal the labeled collection tube and place it in the biohazard garbage bag.


According to convention, you can return the sample to its original packaging for disposal.


Follow CDC instructions for direct treatment of swab specimens or place swabs in medium with or without refrigeration.
