Flocked Swab

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.

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.

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?

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.

Nasal Swab Test

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.

The COVID-19 pandemic has actually added another layer of complexity to the flu season ahead of schedule. COVID and the flu share many similar signs and symptoms, which certainly makes diagnostic screening even more important this flu season.


What is a flu swab test?


Flu is the abbreviation of Influenza. This disease is not unfamiliar to us. It is an acute respiratory infection caused by influenza virus. 


Influenza is very contagious and spreads very quickly. Once you have flu symptoms, you must go to the hospital for relevant examinations in time to determine the type of flu before symptomatic treatment.


Every year when the seasons change, the virus will also increase due to changes in temperature. This period is also the time when we are most prone to getting sick. 


Among them, influenza is a very common epidemic infectious disease. Influenza is familiar to most people, but not very well known to a few people. 


Getting a quick, accurate diagnosis is of course critical to driving treatment decisions.


Influenza testing can be done with blood tests, nasopharyngeal swabs, etc.


How to Test for Flu with a Swab.


How Accurate Is The Nasal Swab
Which Swab Test is More Accurate?


Discovering the right flu test is critical to ensuring accurate results. Using high-quality items—including appropriate swabs, shipping media, and testing devices—can help to properly identify influenza and reduce the potential spread of infection. Influenza testing needs to detect the influenza virus.


 After infection with influenza, the influenza virus usually invades the nasopharynx first, which can be detected by a nasopharyngeal swab. 


Influenza virus can also enter the blood and can be detected by a blood test. Influenza is a relatively serious respiratory infectious disease.


 After the infection, the systemic symptoms are more obvious, such as high fever, general weakness, and sore limbs. 


The recovery of the disease is also relatively slow, and it takes about half a month. 


Each of the influenza tests listed above can be performed using a nasopharyngeal (NP) swab, throat swab, NP swab, nasal or endotracheal aspirate, or saliva test.


Covid Test Throat Swab
Covid Test Throat Swab


To perform an NP flu swab test, follow these steps: 


Choose a flocked swab with excellent absorption and elution, such as CellMedical’s Nasopharyngeal Swab CM-96000N 6″ Sterile Flocked Swab with Breakpoint 90mm. 


With the patient’s head tilted back, slowly insert the flocked swab into the nasal cavity. 


Place the swab directly into the nostril directly back (not up) and at the level of the nasopharynx to the distance determined on the swab handle. 


Rotate the swab approximately 3 to 5 times and hold in place for 5 to 10 seconds to obtain a sample. 


Remove the sampling swab and insert into a virus sampling tube containing 1 to 3 ml of virus transport medium. 


Break the flocked swab along the breakpoint. 


Label the vial with the appropriate customer information.


How long does a flu swab test take? 


Throat swab test belongs to a class of medical test methods. A medical sampling swab is used to take a small number of secretions from the pharynx of the human body, inoculate it in a special petri dish, and then put it into a temperature control device for cultivation. Throat swab test can understand the patient’s condition, oral mucosa and throat infection. As for how long the results will take, depending on the number of people tested, some hours, some a day, some a week.


How accurate is the flu swab test? 


The flu nasopharyngeal swab test is more accurate when the virus load is sufficient. 


This is used to determine whether the human body has the flu. 


But if the test comes back positive, that would require sampling and testing of those who came into contact with the patient. 


It can prevent the spread of influenza, and it is necessary for suspected patients to be properly isolated, placed separately, and tested.


Nasopharyngeal swabs are commonly used clinically to detect viruses. 


That is, take a sampling flocked swab and gently wipe the patient’s nasopharynx, and then take samples for testing.

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
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
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   by  				

			
		


					

				
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
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.


Flocked Nasopharyngeal Meaning Swab Test Sample Collection Vtm Kit
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.

If you are considering whether you should get a COVID-19 swab test, symptomatic or asymptomatic.


Under normal circumstances, the virus is spread through the air to our nose or mouth.


We have to wear masks to prevent the infection of the virus from the source.


Assuming we are unfortunate enough to carry the new crown, the virus will enter the throat through the nose and mouth, and then enter the alveoli through the trachea and bronchi.


At this time, we will use nasopharyngeal swabs and oropharyngeal swabs. The sample is collected from your nasal cavity or mouth when the nurse’s sister gives you a nucleic acid test.


At this time, we will use nasopharyngeal swabs and oropharyngeal swabs, which are the samples taken by the nurse sister from your nasal cavity or oral cavity when you are doing nucleic acid testing.


Due to the convenient operation and high accuracy, these two methods have been widely used. Now I will tell you about nasopharyngeal swabs and oropharyngeal swabs in detail.


What is a nasal swab test?


Specimen Collection Swab
Specimen Collection Swab


Our respiratory tract is divided into the upper respiratory tract and lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. In medicine, the cricoid cartilage is used as the boundary to distinguish.


The nasopharyngeal swab test is a medical test method. A medical cotton swab is used to wipe a little secretion from the nasopharynx of the human body, placing it in a special incubator, and placing it in a temperature-controlled device for cultivation. Can understand the patient’s condition, oral mucosa and pharyngeal infection.


Compared with oropharyngeal swabs, nasopharyngeal swab sampling has the following advantages:


1. When collecting oropharyngeal swab samples, the sampler can see the location of the pharynx to be sampled, and the irritation to the oropharyngeal mucosa may cause the sampled to cough, nausea, and even vomit.


2. When collecting nasopharyngeal flocked swab samples, the irritation to the nasopharyngeal mucosa is relatively small if the operation is standardized.


3. But the sampler cannot see the location of the pharynx for sampling, and mainly relies on the resistance felt by the hand to complete the sampling, so the technical requirements are higher, and the tools used are also more complicated.


4. It can stay in the pharynx for a longer time to obtain a sufficient amount of specimens, which is why the positive rate of the swabs reported in the literature is higher than that of oropharyngeal swabs.


5. The patient’s tolerance is good. After the skilled operation, sampling can be performed without anesthesia, but surface anesthesia and contraction of the nasal mucosa can be performed first for beginners.

Vtm Kit Uses


Sampling using a virus transport medium sampling includes throat swab sampling and nasal swab sampling.


Nasopharyngeal swab sampling:


The collector holds the patient's jaw with the left hand, measures the distance from the tip of the nose to the earlobe with a sampling swab. Marks it with a finger. Insert the sampling swab into the nasal cavity in the direction perpendicular to the nose (face).  The swab reaches the minimum distance.


It should reach half the length from the earlobe to the tip of the nose, let the swab stay in the nose for 15-30 seconds, gently rotate 3-5 times, and withdraw the swab. Wipe the other hole with another swab.


Immerse the swab head in the sampling solution, squeeze the swab head several times in the sampling solution. Break the tail of the swab forcefully, and discard the tail of the swab.


Throat swabs
