what is a flocked swab?

The cell medical company flocking swab is made of nylon fiber flocking technology. The front end of the flocking swab rod is coated with nylon short fiber fixed vertically so that there is no absorption hole in the whole collection swab collection area. Learn more

The sample will not disperse and remain in the fiber, which is conducive to faster and more efficient elution.

To limit the damage to the sample and improve the accuracy of detection, the cotton swab is made of completely inert parts.

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

what are flocked swabs used for?

Flocked swabs are specimen collection devices that are ideal for use in diagnostic testing.

They are capable of efficiently collecting organisms and cells at the collection site and have the ability to rapidly release cells.

If the swab head is flocking, it is a flocking swab.

1. Sample collection and transportation.

The outbreak of the new crown epidemic, no matter where we are. We may have been exposed to nucleic acid testing, and most of the sampling swabs used by medical staff are flocked materials.

The nasopharyngeal sampling swab is composed of a nylon short fiber fluff head and medical-grade ABS plastic rod. The role of nylon short fiber is like a soft brush, which can effectively improve the collection of cell material; the capillary movement between the fibers forms a strong hydraulic pressure, thereby taking in the liquid sample; at the same time, the sample is close to the surface of the swab and is easy to wash.

What Makes Flocked Swabs Different than Traditional Swabs?

We all know cotton swabs, but we may not know flocking sampling swabs.
XiaoLee will discuss with you what flocking swabs are and what are the advantages of flocking swabs over cotton swabs.

Our company uses the existing technology “spraying technology” to vertically attach millions of nylon microfibers to the head of a medical-grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of a 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 thicknesses to make the softness different.

Traditional cotton swabs cannot 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.

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

Our flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability. Learn more

    Cell medical Confirm COVID-19 Diagnostics Cover Omicron Variant

    Cell medical Corporation has announced that its established CE-IVD marked Iclean® SARS-CoV-2 flocked swab real-time multiplexed PCR assay reliably detects all SARS-CoV-2 variants.

    And in addition, is expected to also provide a clear indication of Omicron (B.1.1.529), recently declared a ‘variant of concern’ by the WHO.

    Iclean® SARS-CoV-2 flocked swab is a multiplexed CE-IVD marked PCR assay for the detection and quantification of all major SARS-CoV-2 variants, based on Cell medical´s proprietary technology.

    In addition, the assay simultaneously detects the S-gene mutations Del69-70 and N501Y, which are expected to be clear indications that the variant is Omicron (B.1.1.529).

    The new Omicron variant shares these mutations with the Alpha variant (B.1.1.7), but the Alpha variant is meanwhile of low epidemiological interest and only gets detected sporadically.

    Accordingly, by identifying Del69-70 and N501Y, the laboratory has an indication that the sample most probably is the SARS-CoV-2 Omicron variant.

    This can subsequently be confirmed by genomic sequencing, as is standard practice.

    The Iclean® SARS-CoV-2 flocked swab also provides a viral load result according to WHO standard (IU/ml), as well as CP values and easy interpretation of mutations.

    The test is validated for use with nasopharyngeal and oropharyngeal swabs and contains reagents for 96 reactions.

    Sample extraction, amplification, and PCR results are available in under 3-4 hours.

    Using the Iclean® SARS-CoV-2 flocked swab assay allows the user to run a screening tool for detecting SARS-CoV-2, viral load, and an early indication of the Omicron variant.

    Moreover, Cell medical is pleased to confirm that their full range of other Iclean® SARS-CoV-2 assays is also expected to reliably detect the Omicron variant (B.1.1.529). These assays include:

    * Not for Sale in the USA
    ** Not for use in clinical diagnostics procedures

    All our SARS-CoV-2 assays are CE-IVD-labeled according to the European IVD Directive 98/79/EC.

    And mainly sold into European Markets.

    Iclean® SARS-CoV-2 plus is also registered and sold in some African markets including South Africa.

      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.
      For other information, please visit WTO: COVID-19 symptoms.

      Nasal Swab VS Oral Swab

      Nasal Swab VS Oral Swab

      Nasal Swab VS Oral Swab

      Some customers inquire:

      Are nucleic acid tests all about poking the throat?

      Will you poke your nose?

      “Poke the nose” through the Internet is more accurate,

      is that true?

      Don’t panic, let’s learn about it with Xiao Liu from Cell medical!

       

      When doing nucleic acid testing,
      There is a very important project,
      Just do a throat swab
      There are two types of throat swabs-nasopharyngeal swab and oropharyngeal swab sampling.

      Currently
      Most hospitals use
      Oropharyngeal flocked swab
      Because-it is the most convenient to collect samples and less painful.

      But there are rumors,
      The detection rate of nasopharyngeal swabs is higher,
      is that true?
      Yes! Yes! Yes!
      Studies have shown that the poison load of nasopharyngeal swabs in patients infected with the new coronavirus is much greater than that of oropharyngeal swabs.

      Focus on:
      Wear a mask when you go out!
      Wear a mask when you go out!
      Wear a mask when you go out!

      The important thing is said three times!

       

      Nucleic acid detection, antibody detection

      confuse?

      After the new coronavirus infects the human body, it will first reproduce in the respiratory system. Therefore, it can be determined whether the human body is infected with the virus by detecting the viral nucleic acid in the sputum and nasopharyngeal swabs.
      To
      After a period of infection, usually 7-10 days, the human body will produce specific antibodies against the virus. IgM antibodies will appear first, and then IgG antibodies will appear. Therefore, detecting these specific antibodies can determine whether the human body has been infected with the virus. ,

      If allowed,

      You can, according to your own tolerance,

      Choose whether to do a nasopharyngeal swab or an oropharyngeal swab.

      in addition,

      The serum antibody test is to draw venous blood,

      No need to fast!

      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.

      Flocked Swabs for Sample Collection

      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.

      flocked swabs for sample collection

      flocked swabs for sample collection

      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.

      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.

      About Nylon Flocked Nasal Swab

      Cell medical produces a special flocking swab for coronavirus collection, which has excellent sample collection and release ability, can quickly adsorb micro samples, and has a high release timeliness rate. The increase of the number of targets is helpful to improve the sensitivity of rapid diagnostic test.

      COVID-19 nucleic acid detection is one of the criteria for the diagnosis of cases. It is the key to early detection, early diagnosis, early isolation and early treatment, as well as the basis for isolation treatment of infectious source and medical observation of close contacts.

      Nasal Swab Virus Sampling Kits.

      Nasal swabs PCR test process

      At present, most virus nucleic acid detection kits use fluorescence quantitative PCR to determine whether the sample contains virus nucleic acid by detecting the accumulation of fluorescence signal. So, what steps do nucleic acid detection need to go through? To sum up, there are five steps: sampling, sample retention, preservation, nucleic acid extraction and computer detection.

      sampling

      Collect human secretions. Wipe the nasal cavity or posterior pharyngeal wall and bilateral tonsils with nasopharyngeal swab or pharyngeal swab

      Sample retention

      Immerse the swab head into the cell preservation solution, and tighten the tube cover immediately after breaking the tail

      preservation

      Put the sample tube into a sealed bag, keep it and send it for inspection in time

      nucleic acid extraction

      Send the sample to the laboratory for nucleic acid extraction

      On machine detection

      Good news, recently, Health Canada approved covid-19 rapid test equipment. From now on, this equipment can be used for virus testing all over Canada, and the results can be obtained in 15 minutes at the fastest!

      The number of outbreaks in Canada has soared, and the pressure of virus testing has also soared! Ontario and other places once had to queue up for more than 4 hours to wait for virus testing.

      This will help alleviate the increasing number of confirmed cases and the need for virus testing. Best of all, the rapid test device can be managed by trained professionals in pharmacies and other places, without having to test the results through the laboratory.

      At present, most covid virus tests in Canada are carried out in public health clinics, and then the samples are sent to the laboratory for analysis.

      This process may take several days.

      Bcause some cities are facing the situation that testing centers queue up for hours.

      How much do you know about COVID-19 antigen detection technology?

      In late spring and summer of 2020, the COVID-19 epidemic was initially resurgent beyond all expectations, and unexpectedly came back with a strong attitude.

      “COVID-19” On August 26, 2020, in order to control the spread of the epidemic.Abbottswab.

      In addition, the federal government will spend $760 million to buy 150 million copies of reagents and transport them to nursing homes and schools in about a month.

      Antigen detection.

      By the end of October 2020, with more similar tests under way and waiting for emergency approval.

      Three more antigen test kits have obtained the emergency use authorization (EUA) of the US Food and Drug Administration (US FDA), and the total number has reached 7.

      In addition, although the World Health Organization was unwilling to do so at first.

      It also approved the use of two antigen detection kits following the emergency authorization of the U.S. Food and Drug Administration in September and October 2020.

      In the invention and transformation caused by covid-19 pandemic, detection technology has become a hot spot of biotechnology and engineering innovation.

      In addition, more extensive measures such as wearing masks, maintaining social distance, isolating and tracking contacts.

      And faster and cheaper screening tests provided by Cell medical provide hope for people’s urgent need to combat this infectious disease and make progress.

      Many places in the world that seemed to have controlled the epidemic in the early stage broke out again.

      Which shocked public health experts and called on everyone to carry out rapid and frequent testing.

      Covid 19 self test rapid antigen test.

      According to a report recently released by the Rockefeller Foundation.

      If only to meet the testing needs of primary and secondary schools and nursing homes.

      The United States should complete 200 million rapid tests per month by January 2021.

      Although people tend to detect with higher accuracy, antigen detection with accuracy of only 70% .

      People can also find infected persons omitted from previous tests through frequent detection. And provide sufficient accuracy for continuous screening.

      According to Mara g. Aspinall, a practical professor and medical diagnostic expert at Arizona State University (ASU) in Tempe.

      The co-author of the report, the number of tests required to screen the entire U.S. population may be twice that required by schools.

      “Now it’s time,” Aspinall said. “We have an agreement and testing reagents. I hope the community can reduce the spread of the virus and control the epidemic again.”
