What is a Medical Swab

Posted on 2022年1月5日2022年3月22日 by Dr. Lee

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.

Cell Medical swab

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

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

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

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

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.

Virus Test For COVID-19

In this article：

COVID-19 variants_Omicron;

symptoms;

Swab Test;

COVID-19 is an infectious disease,a respiratory disease.

COVID-19 variants_Omicron

The new findings indicate that the new mutation of COVID-19, Omicron, spread earlier than everyone thought, and the scope is wider.

We must do a good job in vaccine injection and virus swab testing is the top priority.
According to the Associated Press, on Tuesday (November 30), the new findings have clearly shown that Omicron has entered many countries before the world has created its own protection system for Omicron.

The Spanish Institute of Public Health Service and Natural Environment (RIVM) detected Omicron in virus samples on November 19 and 23.

According to the World Health Organization, South Africa first reported this type of mutant virus on November 24.

At this stage, it is still not clear where this type of mutation first occurred, nor how infectious it is, but this has not prevented some countries from rushing to implement travel restrictions, especially for tourists from southern Africa.

This measure has been criticized by South Africa, and the WHO has also expressed its resistance, feeling that its actual effect is relatively limited.

The latest developments have also become increasingly clear that the travel ban cannot prevent the spread of new mutations.

The German government stated that they had seen Omicron in a man who had neither been to Africa nor had any knowledge of anyone who had contracted this type of virus.
The World Health Organization reminded on Monday that the risk of Omicron’s worldwide spread is “very high”, and initial direct evidence suggests that it is likely to be more infectious.

The COVID-19 pneumonia epidemic broke out for the first time nearly two years ago, and at this stage, the world’s response at many levels is similar to the disorder two years ago. Including random implementation of travel restrictions, and the lack of grasp of where there are risks and where there are risks.

Senior officials from all over the world try to clear everyone’s fears, saying that their vaccines are still a better way of defense. Be sure to continue to work hard to make vaccination spread all over the world. At the same time, do a virus swab test.

However, regarding the effectiveness of vaccines against Omicron mutations, although the President of the United States is also urging vaccination, the White House President’s medical consultant and the top infectious disease expert in the United States told the ABC TV program on Monday that the experts look forward to one or two in the future. Understand within a week.

What is the maintenance level of the current COVID-19 vaccine against this new mutation? Don’t know yet. But what we can do is to do a good job of virus swab testing and prevention. For example, go out less and party less.

COVID-19 symptoms;

The symptoms of COVID-19 are likely to include dysosmia, high fever, dry cough, dyspnea, chills, headache, muscle pain, sore throat, hematoma, or runny nose. At the same time, it is manifested as conscious fatigue, weakness, and weakness.
This situation may happen 2-14 days after you touch the virus that causes COVID-19.
Not all COVID-19 patients have all of these symptoms, and some people have no symptoms. That is an asymptomatic infection.
Even after recovering from COVID-19, some people are still likely to have unforgettable illnesses, such as fatigue, dry cough, or joint pain. The long-term physical and mental health hazards are unclear, but they may cause permanent damage to the cardiovascular system, lungs, or other human organs. This is more likely to occur in people with more serious illnesses, but it is more likely to occur even in people with milder illnesses.
If you have symptoms, please take a swab. If you have questions or concerns about a medical condition, please consult your health service provider.

Hot sale product Cell Flocked Swabs

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.

Hot sale product Cell Flocked Swab

What is flocking swab?

Flocked swab refers to the process of applying multiple fibers on the surface of adhesive coating; If the cotton swab is a Flocking material, it is a flocking swab.

It is a one-time sampling cotton swab composed of nylon short fiber velveteen wool head and ABS plastic rod.

It is suitable for oronasopharynx samples, cervix, vagina samples, laboratory tests, etc.

So, what is the difference between flocked cotton and traditional cotton?

Because it does not have the Du cushion core structure of the traditional sampling bed, the sample setting out is difficult, which affects the integrity of sampling.

Compared with cotton swab, the whole sample is adsorbed near the surface of the sampling head and can be released quickly and completely.

The nylon fiber in the vertical direction can improve the cell collection effect as a soft brush. Under the strong hydraulic pressure, the liquid sample is adsorbed on the surface close to the sampling head by nylon fiber bundle, so it is easy to release.

Why is a flocking Swab better than a traditional cotton swab?

Compared with traditional samples, flocking swabs have the following differences.
1. The Cell medical flocking sample sampling swab does not have mutually absorbed nuclei and cannot disperse and collect samples.
2. The flocking cotton swab can be collected quickly, so that the whole sample can adhere to the villus surface and elute fully.
3. The vertical nylon fiber is like a soft bristle brush, which can improve the effect of collecting cell samples.
4. The capillary action between fiber bundles promotes the strong hydraulic absorption of liquid samples and makes the samples close to its surface easy to elute.
5. Flocking cotton swab is an ideal method to collect a large number of cells. It can not only elute quickly, but also release these cells into the delivery medium quickly.

Nasal Swab Pcr Test

Nasal Swab Pcr Test

To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.

This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.

Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.

For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:

1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.

2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.

3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.

4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.

5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.

In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

Quick covid test |How does covid testing work?

Posted on 2021年11月10日2021年11月10日 by Dr. Lee

A new covid test at home has been authorized by the U.S. Food and Drug Administration (FDA) for emergency use (EUA).

Here’s what you need to know about testing at home.

How can I get quick covid test?

Cell medical’s covid test at home now has a prescription, which means Americans can get one from their health care provider.

If doctors suspect that their patient is infected with covid – 19 within the first six days of symptom onset, they can prescribe a rapid test.

Quick covid test Rapid Antigen Test Kit Nasal Saliva Test at home

How much does it cost?

Please contact us for more details.

E-mail：flockedswabs@gmail.com

How does testing work?

Rapid Antigen Test is a lateral flow test, a portable covid test that usually returns results faster than the widely used laboratory based PCR test.

It works by detecting nasal swab samples and provides positive or negative results within 10 minutes. The results appear on test strips exposed to nasal swab samples.

The FDA said flocked swab can be collected from people aged 8 and over, but if the tested children are less than 14 years old, it should be collected by adults.

How accurate is the test?

Cell medical claimed that the time when the positive results of the test matched the PCR test was 84.8%, and the negative results matched the PCR test were 99.1%.

FDA said that the negative test results of covid test do not necessarily exclude the possibility of covid – 19 infection.

“and should not be used as the only basis for treatment or patient management decisions, including infection control decisions.

“People who are negative and continue to experience COVID 19, have a fever, cough and / or shortness of breath, may still have SARS – CoV – 2 infection. Follow up care should be sought from doctors or medical staff. ”

Not all side flow tests require the use of prescriptions. On December 15, the FDA issued the EUA for the first outside counter flow covid test at home.

The covid – 19 family test also uses nasal swab samples to detect covid infection and works with people aged 2 years and older.

The FDA said that in the population with covid symptoms, the ellume test correctly identified 96% of positive samples and 100% of negative samples. In the population without symptoms, it collected 91% of positive samples and 96% of negative samples.

Similarly, the FDA said that the negative results of the test do not necessarily exclude the possibility of covid infection.

Broader prospects

According to CDC data, as of Monday, the United States had reported 47.5million cases of covid and 778,316 deaths.

The data also showed that 432 million people were vaccinated on Monday.

A stock photo shows a schoolgirl receiving a nasal swab sample.

The covid test uses self collected swab samples.

But adults should take samples from children under the age of 14 and over the age of 8.
