Nylon Flocked Swab

Posted on 2022年10月17日2022年10月17日 by Dr. Lee

93050 Throat sampling swab, ABS rod + nylon fluff head, used for sampling, the release rate is as high as 90%.

The nylon flocked swab is a honeycomb swab best suited for specimen collection. The nylon flocking technology has greatly improved the collection ability and elution ability of a sampling swab. And the flocking swab also marks the latest development of single-use specimen collection equipment. Flocking, which refers to the vertical attachment of long fibres to an adhesive-coated swab shaft, has a distinct advantage when collecting samples.

Features of flocked sampling swabs:

1. Swabs using jet-dense nylon fiber technology.

2. According to different analysis items, there are soft or brush texture swabs, and the collection volume has reached the limit.

3. Disposable sterile injection-moulded swab rod with breakpoint.

4. The flocking swab technology improves the adsorption/release of the specimen and improves the sensitivity of the analysis.

5. No sample retention, indicating faster and less sample transfer.

Used in the medical industry, such as collecting liquid microorganisms.

such as human mouth, nose, throat, cervix, DNA, viruses, bacteria, etc. Medical nylon flocking swabs are the best for sample collection.

As a professional sampling swab manufacturer, many people will ask us why we use flocked sampling swabs? You will know by looking at the comparison below.

Nylon flocked swabs: maximum sample collection/release capacity, release rate >80%

The acquisition is slow, the release is even slower.

The time for flocking swabs to collect samples is 3-5 seconds, while the time for cotton swabs is 15-120 seconds, or even longer, which causes pressure on staff during the diagnosis process. Only faster sample extraction can complete the collection and analysis more efficiently.

The sampling flocking swab is 3 times higher than the traditional wrapping swab to collect and release the sample, and it does not cause damage to the cell sample. It will not cause harm to the human body.

In short, the upright nylon fibers act like a soft brush to collect more cell samples. The capillary action between nylon fibers enhances the loading of aqueous samples, and the samples are concentrated on the surface of the swab for easier elution. Nylon flocked swabs can absorb and release more samples.

The nylon flocked swab is a honeycomb swab best suited for specimen collection. The nylon flocking technology greatly improves the collection and elution capacity of a single sampling swab. Flocked swabs also mark the latest development in single-use specimen collection devices. Flocking, which refers to the vertical attachment of long fibers to an adhesive-coated swab shaft, has a distinct advantage when collecting samples.

Combined Throat And Nose Swab

Posted on 2022年5月10日2022年5月10日 by Dr. Lee

What is the difference between a nasal (Nose) swab and a throat swab for nucleic acid testing

The sampling method and location are different. The accuracy rates of the nucleic acid test ( PCR Test ) nasal swabs and throat swabs are usually similar, and the main difference lies in the sampling method and sampling site. For nasal swabs, nasopharyngeal swabs (flocking swabs) are mainly used to test the secretions from the inside of the nasal cavity and the surface of the nasal mucosa through the nasal cavity;

Throat swabs: Health care workers collect samples in the mouth with oropharyngeal swabs. Health care workers take throat samples for testing to determine whether a patient has the new coronavirus.

Are both throat swabs and nasal(Nose) swabs required?

Let’s talk about throat swabs first.
The “oral sampling” and “nasal sampling” mentioned above are actually test methods in which medical staff use medical swabs to collect samples from the pharynx in nucleic acid testing (PCR).

COVID-19: Will The Pandemic End in 2022?

It is very important to continue swab testing while the pandemic is still ongoing

Whether entering from the nasal cavity or the mouth, the specimens we need to collect are pharyngeal secretions, including sputum. Compared with the oral route, nasal sampling can provide better safety protection for the sampling person. Because oral sampling requires subjects to open their mouths wide, this increases the risk of virus transmission by droplets. However, if it is collected through the nasal cavity, the environment is relatively stable, and the medical staff who operate it will be safer.

What is the difference between a throat swab and a nasopharyngeal swab, which is more accurate?

The main difference between nasal swabs and throat swabs lies in the location and material of the specimens, which are usually as accurate. The throat swab is in the pharynx, and the nasal swab needs to go into the nasal cavity, not the external nasal cavity. It needs to use a longer swab and slowly rotate it to the deep part of the nasal cavity, so the parts of the material are different. Nasal swabs are special, and the material is relatively soft, which is convenient for reaching the deep nasal cavity through the nasal cavity. The process of taking it may take longer than that of throat swabs.

Compared with nasopharyngeal swabs, oropharyngeal swab sampling is sometimes difficult to meet the normative sampling requirements due to irritating reactions, and the actions of eating, drinking and swallowing will reduce the oropharyngeal to a certain extent. The virus enrichment of 2000 may affect the positive detection rate of oropharyngeal swabs.

Which is better, nasal(Nose) swab or throat swab?

No matter which one is adopted, the key lies in the depth of the collection, whether the collection is in place and the length of contact time with the deep mucosa.

From the personal experience of the testing population, throat swabs will be less irritating and uncomfortable than nasal swabs.

Sterile Flocked Swab

Oropharyngeal swab

　　• The operation is relatively simple and less irritating, suitable for large-scale screening.

　　• The sampling staff will guide the subject to open the mouth, and then use a sterile long cotton swab to gently scrape the subject’s throat to collect secretions from both palatine arches, pharynx, and tonsils.

Nasopharyngeal swab

　　• The technical requirements are high, the human body does not feel very comfortable, and the accuracy is higher than that of oropharyngeal swabs. For key groups such as isolation points.

　　• The sampling staff will insert a long sterile cotton swab into the nostril of the subject, and reach the mucous membrane deep in the nasopharyngeal cavity, stay for a few seconds to soak the secretion, and then take it out.

Who is not suitable for nasal swab

What is A Covid-19 NP Swab?

When collecting nasal swab specimens, the flocked swab ( learn more ) will enter the nasal cavity.

f the medical staff operates in a standardized manner, it will reduce the irritation to the mucous membranes.

But because we can’t see the sampling position of the pharynx.

It mainly relies on the hands of medical staff to feel the resistance, so the technical requirements of the operator are very high, and the tools used are also more complicated.
The improper operation will cause certain irritation to the nasal mucosa, so it is not recommended for patients with sinusitis and allergic rhinitis to do nasal swabs to avoid damage to the nasal cavity.

How to overcome the discomfort of throat swab

When collecting throat swab specimens, the oropharyngeal flocked swab will cause certain irritation to the pharynx. For some people with the sensitive pharynx, nausea and vomiting may occur.

Recommended to relax before collecting specimens.

Don’t get too nervous. If you feel discomfort in your throat after collection, you need to eat less spicy, irritating and greasy food, drink more water, eat more vegetables and fruits, and arrange rest appropriately. Generally speaking, it does not take long to return to normal.

Experts said that the study found that the nucleic acid-positive duration of feces or anal swabs of some infected people is longer than that of the upper respiratory tract. Increasing anal swab sampling can improve the detection rate and reduce missed diagnosis; but anal swab sampling is not convenient enough, and currently only for isolation. Points and other key groups to use.

What Is Specimen Collection ?

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?

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.

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) ).

Our GMP Factory Flocked Swab Ethylene Oxide Covid Test

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;
