The outbreak of the novel coronavirus pneumonia in 2020 on a global scale has brought significant losses to human society. Viral nucleic acid detection plays a key role in epidemic prevention and control.

As the first step in viral nucleic acid detection, specimen collection is an indispensable link.

The amount of virus collected and released by sampling swabs is directly related to the positive rate of nucleic acid detection. As the gold standard, nucleic acid detection plays an important role in virus detection, and the role of swabs as a sample collection tool should not be underestimated. Among them, throat swabs and nasal swabs are most commonly used, and anal swabs are also used as auxiliary tests.

During the epidemic, researchers from various countries analysed and found that the efficiency of flocking nasal swab sampling and the acquisition of virus samples were the best.

At the same time, in order to solve the problem of the shortage of nasal swabs.

Nasal swabs

The researchers proposed a combined sampling method of oropharyngeal and nasal swabs to achieve the same effect as nasal swabs.

As the main tool for sampling, swabs have important applications in the fields of forensics, clinical medicine, and environmental testing.

Swabs of different materials, such as rayon, foam, polyurethane, polyester, flocked nylon, etc., will have different structures and performance differences and have different collection effects for different specimens such as protein and nucleic acid, which will affect the detection.

The selection of appropriate swabs according to different sampling samples and testing indicators is very important for testing, and the proper use of swabs is also very important for sample collection and the safety of medical staff.

ISO13485 quality management system for producing disposable sampling swabs, quality standards, and sterile swabs.

Nylon flocking swabs–small nylon fibres to a moulded plastic rod.

This production process significantly increases the surface area of the nylon swab, which is conducive to the adsorption of bacteria and easy release.

Oral Foam Swabs 104mm (with 22mm breakpoint)

The sponge swab is soft in texture and has numerous tiny pores. It has strong adsorption to liquid, can collect more target analytes, increase the number of samples collected, and can release a large number of samples without defibrillation.

How to elute, etc., which will affect the test results. Many factors can affect the swab sampling results.

The cotton swab used to poke the throat or nose during the nucleic acid test of the new crown should be called an aseptic sampling swab, also called a pharyngeal swab. According to different sampling sites, including nasopharyngeal swabs and oropharyngeal swabs.

The swab is in direct contact with the nasopharynx or oropharynx to absorb the secretion sample, then put the head with the secretion into the culture solution, break the handle through the breakpoint, seal the lid and send it for testing.

Nasopharyngeal Sampling Procedure

In this process, the swab involves two links: sampling and elution (release the collected sample into the culture medium). The choice of different materials will affect the efficiency of sampling and release, and also affect the correctness of PCR detection. There are certain requirements for the material of the sampling swab.

PCR TEST

According to different materials, common swabs can be divided into medical cotton swabs, foam swabs and flocking swabs.

Several reports have shown that the sensitivity of medical cotton swabs in collecting respiratory samples is low, and natural fibres such as cotton have strong adsorption to proteins, which is not conducive to the subsequent release in the culture medium.

Generally, cotton swabs also have wooden handles, which may adsorb proteins during storage and interfere with virus detection. In addition, the wooden handle is too hard to break, and can also cause safety problems when sampling.

The US CDC recommends that the swab head material— synthetic fibres. The use of calcium alginate swabs or swabs with wooden shafts may inactivate certain viruses and reduce Accurate substances.

Flocked Swabs For Sample Collection

Posted on 2022年6月10日2022年6月10日 by Dr. Lee

The nucleic acid test (PCR TEST) uses a flocked swab instead of a cotton swab.

Flocking is a craft, not a material

　　 Flocking is not the fluff of any plant, but a very common fabric treatment process.

Widely used in the textile industry, automobile manufacturing, printing industry, chemical industry and other fields.

　　 The flocking process means vertical fixing of some cut or milled short fibres to some kind of adhesive-coated surface. Short fibres are usually nylon, polyester, or other artificial fibers. The range of planting them is very wide, and surfaces such as cloth, plastic, wood, leather, paper, etc. can be flocked.

　　Flocking only needs three things, 1, short fibers; 2, adhesive, 3, some kind of surface

　　 Flocking is very common in everyone’s life, just usually without realizing it. For example, flocking fabrics can be found on clothes, curtains, carpets, and furniture. Usually, those surfaces that are fluffy and comfortable to the touch are brought by the flocking process.

　　 In addition to the decorative effect, the flocking technology has also been tried by scientists to make graphene lithium battery anode sheets; make special lipophilic and hydrophobic materials to absorb marine oil spills, etc.

The principle of flocking

　　 At present, the most commonly used flocking method is electrostatic flocking. After the fluff enters the high-voltage electric field, it contacts the negative electrode and is negatively charged.

　　 Don’t worry if some fibers fall to the side and don’t stick to the side. After they touch the positive electrode side, the negative charges on the surface are completely neutralized, and they will fall to the negative end due to the force of the electrostatic electric field. Repeat the above movement until they are all stuck.

Flocked swabs for nucleic acid testing

　　 The flocking swabs used for nucleic acid detection are mostly “planted” with nylon short fibers. The reason for choosing flocked nylon over cotton swabs is the functional need for sampling.

Flocked swab

Any material design is purposeful, and flocked swabs for nucleic acid detection need to meet the following characteristics:

　　 ② After the swab is put into the preservation solution, it has to “let go” to release the biological sample, and it cannot hold the sample firmly for a second or divide it. ③ It cannot react with biological samples and destroy the samples.

　　 Because cotton itself has superior hydrophilicity and adsorption, once it comes into contact with the sample, it is like the characters in Qiongyao play. In contrast, nylon flocked swabs are like a scumbag “can take it and put it down.

　　 Therefore, the collection and release volume of nylon flocking swabs is much larger than that of traditional winding cotton swabs. Experimental studies have shown that the collection and release volume of flocking swabs can reach 95% of the samples, while cotton swabs are only about 20%.

　　In fact, the ability of cotton swabs to grasp the sample is not bad, but after inserting the preservation solution, the flocked swab can quickly let go of the sample to be eluted, but the cotton swab will make the cells stuck in the fiber mass and cannot be separated.

　Otherwise, the nucleic acid will be degraded before the detection begins, and the correct result will definitely not be detected.

　　 Because of this, it is superfluous to worry that nylon is a synthetic fiber that is harmful to the human body. Flocked fibers have even been tried in regenerative medicine to help repair damaged bones and cartilage. By implanting the flocked fibrous scaffold, the properties of the extracellular matrix are modeled, allowing stem cells to adhere to it to proliferate and differentiate; and provide sufficient space for the newly synthesized matrix and capillaries to enter.

When it comes to flocking sampling swabs, many people may only know that they are used for sampling by name, but they may not know the specific details. So what are flocking sampling swabs usually used for?

Throat swab: Professional operation is required, because the throat is more prone to injury, flocking swabs are the first choice.

ISO13485 quality management system for the production of disposable sampling swabs, quality standards, sterile swabs, disposable oral swabs, DNA flocking swabs, flocking swabs, foam swabs, disposable sterile swabs, disposable DNA swabs, Disposable virus sampling tube, oral cotton swab, sponge cotton swab, cloth tip cotton swab, cotton swab, medical cotton swab flocking swab.

Our factory specializes in the production and operation of: medical equipment flocking cotton swabs. Flocking sampling swabs: (DNA sampling swabs, cleaning verification cotton swabs); DNA extraction reagents and other products. The company has the right to import and export, and has obtained the certificate of free sale of medical equipment. Products are exported to Europe, America, Southeast Asia, the Middle East, Japan and South Korea. Send the sample to the laboratory for analysis. High quality sampling swab wholesale factory.

1. What is a flocking swab?

Flocking refers to the process of applying multiple lengths of fibers to an adherent coated surface; if the tip of the swab is flocked, it is a flocked swab. It is a disposable sampling swab composed of nylon short fiber fluff head and abs plastic rod. For oral nasopharynx, sampling, cervicovaginal sampling, laboratory testing, etc.

Flocked sampling swab samples are easy to collect.

2. What are the advantages of flocking swabs for DNA collection?

Sample collection process: The unique structure of the flocked swab tip can greatly increase the number of samples collected

Sample extraction process: The brush-shaped layer structure can release approximately the entire collected sample.

3. Why use flocking sampling swabs? You will know after reading the comparison below.

Conventional fiber swab: The sample is trapped by the gaps in the fiber mass, that is, the sample is penetrated, diluted, and trapped in the fiber. The acquisition is slow, the release is even slower.

Nylon flocked swabs: Superior sample collection/release capability, >80% release rate

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.

3. Why are flocking swabs more advantageous for micro DNA collection?

Due to the internal structure of traditional cotton swabs, which are entangled with cotton fibers at the top, the sample will be dispersed by its fiber clusters and remain in the fibers during sampling, resulting in lower precipitation efficiency of DNA with low content, and even causing false negatives in the test. result.

The unique structure of the top of the flocking swab can almost completely extract and separate out a very small amount of DNA, so the flocking swab has a more obvious advantage in the collection of trace DNA.

3, ethylene oxide sterilization, independent packaging;

sampling step

Flocked Swabs and Custom Swab Manufacturing

Swab Step 1: Hold the handle and gently insert the sampling swab into the mouth.

Step 2: Gently rotate the sampling swab for 3-5 turns, then slowly take it out

Step 3: Put the extracted sample into the sample collection tube, break the handle, and seal it immediately to complete the sampling.

The newly developed sampling swab nylon flocked sampling swab head has soft flocking hair, and the absorption and release force is 3 times greater than that of trapping microorganisms in traditional sampling swabs, and it will not cause epithelial damage to patients.

The short nylon fibre acts like a soft brush, which can effectively improve the collection of cellular material; the capillary movement between the fibers forms a strong hydraulic pressure, thereby ingesting the liquid sample; at the same time, the sample is close to the surface of the swab and is easy to elute.

Influenza requires a throat swab test. Tests can be used to determine whether a patient is infected with the flu virus, and then targeted treatment can be given.

Influenza patients will have symptoms of dry cough, and they will also have dry cough symptoms after being infected with the new coronavirus, so throat swab tests should be performed for patients who have been in contact with people infected with the new coronavirus or who have been to the epidemic area. Patients infected with the new coronavirus generally do not need a throat swab test to determine whether they are infected with the new coronavirus.

Covid Test Flu Throat Swab

The throat swab detection process is as follows: the tested person needs to sit facing the sampler, raise his chin, and open his mouth wide. in special equipment.

These tests include reverse transcription-polymerase chain reaction (RT-PCR), viral culture, and immunofluorescence assays. All we require is that a health care provider swipe the inside of your nose or the back of your throat with a swab and then send the swab for testing. Results may take one to several hours.

Accuracy of throat swabs for influenza.

A throat flocked swab for influenza is more accurate, but there are no authoritative experimental statistics for its specific accuracy.

Throat swab testing for influenza is very fast, economical, and simple, but if the throat swab is negative.

It does not mean that there is no Influenza that may be caused by contamination of specimens, improper sampling of specimens, etc.

And comprehensive judgment should be made in combination with clinical symptoms, epidemiological history, and antigen testing.

When taking a throat swab for influenza, insert the swab completely into the throat from the oral cavity, and moderately wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall with the throat wall and the reddened part of the palatine tonsil as the centre. But avoid touching the tongue. Then remove the test strip. Insert the sampled swab into the solution in the sample extraction tube

So that the specimen is dissolved in the solution as much as possible, and the results can be observed within 15 to 20 minutes.

After more than 30 minutes, the displayed results are usually not clinically meaningful.

If there are two red lines or three red lines in the patient, it means that the throat swab test for influenza is positive.

And there are two red lines, which usually means that there is influenza A or B. If it is three red lines, it means that it is a mixed infection of influenza A and B.

If only one red line appears, the throat swab is negative.

If the reaction line does not appear, the test is invalid, and it is recommended to use a new test card to test again.

Is it a cold or the flu? How to distinguish?

1. Influenza: fast and furious,

If you feel like you’ve been hit by a truck, you might have the flu. Symptoms such as sore throat, fever, headache, muscle aches, congestion and cough can come on suddenly. Colds are usually less intense and include a runny or stuffy nose. The flu gets better in 2 to 5 days, but you may feel the discomfort for a week or more. Colds come on slowly and last up to 10 days.

2. Fever: Usually means the flu

While some people have a mild fever when they catch a cold, most do not. If you have the flu, your body temperature may reach 38-40°C. The flu tends to be higher in children, and children may also be more likely to develop a fever.

3. Flu: Fatigue can last for weeks

You may start to feel very tired and sore. Fatigue and weakness can last up to 3 weeks, and even longer in older people and people with long-term (chronic) illnesses or weakened immune systems. Colds are self-limiting and you usually get better within a few days, usually 1 week to 10 days.

4. Cold and flu: Both can cause headaches

Like other symptoms caused by a cold, headaches that accompany a cold are still milder than those caused by the flu.

5. Cough: Both colds and flu can cause

Colds and flu are respiratory illnesses that both affect your airways, so both can cause a cough.

Pneumonia is a lung infection that can be a complication of the flu. If you have a persistent cough, fever higher than 38°C, chills, difficulty breathing, shortness of breath or chest pain, please seek medical attention in time.

6. Earache: Maybe from a cold or the flu

Congestion from either disease can raise the pressure in your ears. This affects the Eustachian tube, where the larynx and middle ear communicate. It may cause dull ear pain, hearing loss, and a “popping” feeling in the ears. These symptoms will disappear as the disease improves.

If other symptoms get better and the earache persists or you experience sudden, intense pain, see your doctor. You may have an ear infection that needs treatment.

7. Colds: Usually starts with a sore throat

These early symptoms tend to last 1 to 2 days, and a runny nose and nasal congestion are also common. A sore throat also accompanies the flu, but if it’s the flu, you may feel tired and have other symptoms right away.

8. Stuffy nose: Could mean a cold

Simple nasal congestion without fever and general tiredness tends to lead to a cold, although many flu sufferers also say they have nasal congestion and sneezing.

Both colds and flu can cause sinus infections. In addition to a thick yellow or green snot, a sinus infection can also cause headaches and pain in the forehead, cheeks, and bridge of the nose. Sudden head movements or strains can make the pain worse.

9. Flu throat swabs can quickly identify the flu

Flu Test Throat Swab China Factory And Manufacturers

ABOUT US

The quickest way to find out about your illness is to go to the hospital for a checkup.

A nasal or throat swab can usually tell you if you have the flu virus in 30 minutes or less. If a test shows you have the flu and your symptoms started within the past 48 hours, your doctor may recommend antiviral medication to help you recover faster.

10. Influenza: start antiviral drugs as soon as possible

These medications can give you relief and shorten your condition within 1 to 2 days, especially if you start taking them within 2 days of getting sick. Over-the-counter medications can also relieve symptoms such as coughing and congestion. Read labels and directions carefully so you know what the medicines do and how to use them.

11. Colds: Over-the-counter medications can ease symptoms

12. Hand washing is key

Washing your hands is very important to protect yourself and not spread the flu to others. Wash your hands with soap and warm water, preferably the six-step method. Alcohol-based hand sanitizers are also effective.

Wash your face frequently during cold and flu season, especially after coughing, sneezing, or having a runny nose. What if I can’t find a tissue? Face your elbow when sneezing or coughing instead of covering your mouth with your hand.

13. Get vaccinated

There is now a flu vaccine that protects against the flu, and it’s made from a protein from the previous year’s flu cases. It helps your body prepare to recognize and fight when you’re exposed to the virus again. Note: The flu shot won’t give you the flu!

The flu shot is very important for children over 6 months of age, pregnant women, adults 50 years and older, and people with long-term (chronic) illnesses or weakened immune systems.

Monkeypox Virus Outbreaks Are Containable

Posted on 2022年5月24日2022年5月24日 by Dr. Lee

Monkeypox Virus Outbreaks Are Containable, WHO said available details indicated that human-to-human transmission was occurring among people who had close physical contact with symptomatic cases. The patient’s symptoms were similar to those observed in smallpox patients in the past but were less clinically severe.

These confirmed and suspected cases are mainly from the United Kingdom, Spain and Portugal, with the rest in Australia, Belgium, Canada, France, Germany, Italy, the Netherlands, Sweden and the United States.

The incubation period for monkeypox is usually 6 to 13 days, but it can be between 5 and 21 days.

However, Nick Finn, deputy director of England’s National Infectious Service, stressed that monkeypox does not spread easily from person to person and that the overall risk to the public is low.

An expert from China’s disease control system also told Caijing·Great Health that the spread of monkeypox between people can be said to be very limited, mainly through secretions and other transmissions, and the risk of causing an epidemic is very limited.

How serious is a monkeypox infection?

Before the current outbreak, monkeypox cases scattered in the tropical rainforests of central and western Africa.

Monkeypox Virus VTM Kits

There are two distinct clades of monkeypox viruses, the Congo Basin clade and the West African clade. Monkeypox, caused by the Congo Basin clade virus, has reported a mortality rate of up to 10.6%; while the West African clade virus, which usually causes less severe disease, has a case fatality rate of 3.6%.

In this outbreak, all cases with samples confirmed by polymerase chain reaction (PCR) testing were determined to be infected with the West African branch, meaning relatively low mortality.

The genome sequence of a swab sample from a confirmed case in Portugal showed that the monkeypox virus responsible for the current outbreak closely matched cases exported from Nigeria to the UK, Israel and Singapore in 2018 and 2019.

Initial symptoms of monkeypox infection include fever, headache, swelling, back pain, muscle aches and general weakness. Infected individuals initially have generalized erythema or rash, which then develops into papules on the trunk, face, palms, and soles, which then develop into cysts, which form pus scars and scabs. Sometimes a bit like chickenpox, the infection lasts 14 to 21 days and usually goes away on its own.

The virus can enter the body through broken skin, the respiratory tract, or through the eyes, nose, or mouth. Evidence suggests that the highest risk of infection is in people who have had close physical contact with a symptomatic monkeypox patient.

Of the first nine cases of monkeypox confirmed in the UK, six had had sex with men.

To date, severe cases are more common in children and immunocompromised people, especially those with HIV, and are related to the degree of exposure to the virus, the patient’s health status, and the severity of complications.

Hans Kruger, WHO Regional Director for Europe, also said: “Monkeypox is usually a self-limiting disease and most infected people recover within a few weeks without treatment.

How to get out of Africa and into Europe?

Confusingly, monkeypox occurs primarily in the rainforest regions of central and western Africa. For example, the US recorded two cases of monkeypox in 2021 and the UK reported seven cases, all imported to and from Nigeria. travel history.
However, in this outbreak, it is unusual for confirmed and suspected cases reported in several countries without any travel history to monkeypox-endemic areas.
Australia, Canada and the United States are also among the non-endemic countries reporting monkeypox cases. Health authorities in New York City, home of the United Nations, are also investigating a possible case. A patient at a hospital tested positive on May 19, local time.
These cases are atypical, Hans Krueger said. All but one were not related to travel to monkeypox-endemic countries.
WHO believes that there is an urgent need to raise awareness of monkeypox and implement comprehensive measures to detect and isolate cases, trace contacts, and provide supportive care to limit further spread.

How to stop the spread.

“China has not reported any cases of monkeypox, nor has the virus been found in animal hosts. The current focus is on preventing imported cases,” Tan Wenjie, a researcher at the Chinese Center for Disease Control and Prevention’s Institute for Viral Disease Prevention and Control, said in an interview with the media. (Transport medium )

According to the above-mentioned experts of China’s CDC, at present, the measures to prevent the importation of the monkeypox virus are very strict. Import squirrels, rabbits and other rodents. The possibility of monkeypox being introduced by animals brought by inbound passengers is unlikely and the public need not worry.

Specifically, researchers don’t yet know the animal reservoir of the monkeypox virus.

Since 1970, the monkeypox virus has had sporadic outbreaks in 10 African countries. This is a DNA virus in the genus Orthopoxvirus of the Poxviridae family. In 1958, a group of captive monkeys transported from Africa to Copenhagen, Denmark for scientific research developed the vesicular disease. European scientists isolated the monkeypox virus from monkeys in the laboratory, hence the name “monkeypox virus”.

In 2017, Nigeria experienced its largest outbreak on record. At that time, there were 172 suspected cases, and 75% of the patients were men, aged 21-40. Since then, Nigeria has continued to report monkeypox cases.

Of these, 241 were confirmed cases, including 8 deaths (case fatality rate 3.3%). From 1 January to 30 April 2022, 46 suspected cases were reported and no deaths were recorded.

In 2003, there was an outbreak in the United States, the first time the disease had emerged outside of Africa. The patient was infected due to close contact with marmots. Marmots were infected by various small mammals imported into the United States. There were 81 cases at the time, but there were no deaths.

The cases of monkeypox infection have emerged in multiple countries, and researchers suspect that transmission may have continued for some time because all but one of these cases were not related to travel to monkeypox-endemic countries and were geographically dispersed in Europe and elsewhere.

Matthew Kavanagh, acting deputy executive director of WHO’s AIDS agency, stressed on May 22 that leaders urgently need to strengthen their pandemic preparedness. Including building stronger community-led capacity and human rights infrastructure to Support an effective and de-stigmatizing response to the outbreak.

The above-mentioned experts in the disease control system explained to Caijing.

However, the “early detection” of the monkeypox virus is difficult. The above-mentioned experts in the disease control system said that it takes a certain period of time for monkeypox infection to have clinical symptoms and thus be discovered, which is different from the emergence of viral symptoms in respiratory infections.

The nylon has stuck vertically and uniformly to the surface of the swab pointer, which can boost the effectiveness of accumulating as well as releasing cells as well as liquid samples. Improve analytical level of sensitivity, No sampling recurring, and can speed up the specimen therapy. PS sticker label is very easy to break short. Adjusted to cervix wombs, nasopharynx, oral cavity, Forensic Purchase System as well as DNA accumulating, etc. Private stuffed.

Features

1. Flocked swabs provide the best sampling effect. Groups of swabs are the best choice for rapid diagnostic testing because they can better collect cells or organisms at the collection point and quickly release intact cells.

2. Enhance the sensitivity of diagnosis. The patented flocking technology turns each strand of fibre into a velvet brush, resulting in hundreds of thousands of contact points, which can better collect and release samples. The increase in the number of target cells (compared with non-flocking swabs) helps to improve the sensitivity of rapid diagnostic tests.

3. The flocking swab with rapid elution of CellMedical is closely combined with the handle and does not contain the internal fabric or other inner cores that absorb the samples, which can collect and retain more samples. This can not only provide a better sample size but also make the sample released into the liquid medium more quickly and completely.

4. Proprietary long flocking fibre flocking swab the proprietary long flocking fibre forms a network structure, which can collect and retain more specimens than traditional cotton, polyester or man-made fibre swabs. The inner core of an ordinary cotton swab will easily lock the sample, making it difficult to elute and pour it into the medium.

5. Convenient handling and transportation. Most oral, oropharyngeal and nasopharyngeal flocking swabs have prefabricated breaking points, so you can easily break the handle before putting the swab into the vial. Sterile flocking cotton swabs will also be equipped with dry transport tubes and media filling transport tubes and other transport materials. After sampling, the storage and transportation can be completed conveniently.

In a word, a flocked swab can better meet the sample collection needs of laboratories, hospitals and other institutions. It is the preferred tool for sample collection and elution.

COVID-19 Swab Test: What You Should Know

Posted on 2022年5月13日2022年5月13日 by Dr. Lee

An abrupt COVID-19 has brought flocking swabs, nasopharyngeal swabs, oropharyngeal swabs, nucleic acids, antigens, PCR and also other extremely professional terms right into the public eye. Today, CellMedical will certainly offer you preferred scientific research: those aspects of Coronavirus (COVID-19) screening.

What is a flocking swab, nasopharyngeal swab, or oropharyngeal swab?

When nations are executing a new round of nucleic acid screening, a report is spreading out in circles. The basic concept is “the cotton bud used for sampling have reagents on them, which are hazardous”. Some netizens also left a message to the CellMedical firm backstage, saying that after seeing the pertinent reports, the elderly at home shared that they did not want to take part in nucleic acid testing, and also really hoped that the younger generation would additionally attempt not to undertake nucleic acid testing as well as antigen testing.

“The covid test swab is not the same as the cotton swabs used in daily life, but it does not contain reagents, nor is it toxic”. ( Click here to learn more )

What is a flocked swab and why choose flocked oropharyngeal and nasopharyngeal swabs?

A flocked swab is used because it is more suitable for sampling and testing. The flocking swab(learn more) is made of nylon fiber flocking technology, and the front end is coated with nylon short fibers fixed in a vertical manner, so that there is no absorption hole in the entire collection area of the collection swab. In this way, the collected sample is not dispersed and retained in the fiber, which facilitates faster and more efficient elution. Relevant data show that CellMedical flocked swabs can elute more than 95% of the sample collection volume; traditional cotton swabs, especially those made of absorbent cotton, cannot completely collect and elute samples.

Nasopharyngeal swabs – which require a swab inserted into the nose to collect samples from the back of the nose and throat – are the gold standard for collecting samples for diagnosis. But the process is technically difficult, often uncomfortable for patients, and requires personal protective equipment that may be in short supply.

Oropharyngeal swab – the oropharyngeal swab is a method of collecting oropharyngeal specimens by entering the sampling swab through the mouth – compared with a nasopharyngeal swab, it is less difficult, more acceptable to the public, and more universal.

What exactly is PCR nucleic acid detection?

PCR (Polymerase Domino Effect, polymerase chain reaction) innovation is a wonderful creation, without the creation of PCR modern technology, there would be no modern-day molecular biology. Nucleic acid detection modern technology has likewise entirely transformed several techniques such as genetics, medication, and also forensics, allowing human beings to accomplish significant steps such as hereditary testing, viral infection identification, and also genetic testing.

Basically, PCR nucleic acid detection: To significantly magnify nucleic acid till it can be identified by equipment detection. Yet if you increase the size of the nucleic acid, 1 ends up being 2, 2 comes to be 4, and also 4 ends up being 8. Consequently, PCR innovation is a method of amplifying nucleic acid.

After the covid-19 contaminates the human body, it will initially increase in the respiratory system. So it can be determined whether the body is infected by finding the viral nucleic acid in sputum and nasopharyngeal swabs. After a duration of infection, typically 7-10 days later, the body will certainly create specific antibodies versus the virus. IgM antibodies show up initially, adhered to by IgG antibodies. So immunological discovery approaches can identify these specific antibodies to identify whether the human body is carrying the virus.

Will the results from different nucleic acid testing institutions be consistent?

PCR nucleic acid detection has a strict standard procedure. It is the same SOP (Standard Operation Procedure). At the exact same time, all nucleic acid labs, regardless of dimension, must adhere to the same technological demands, and also the design and building of laboratories additionally have uniform specifications. Also, research laboratory screening staff have to go through standard technical training and also acquire a nationally identified task certification before they can work. It resembles KFC’s fried chicken all use the exact same dish. Whether it’s a fast window in the station, a sizable and comfortable dine-in in the town hall, or home delivery, you can constantly eat deep-fried chicken with the exact same preference, do not fret will certainly strike rumbling.

Therefore, no matter which institution we conduct nucleic acid testing, the outcomes need to coincide.

The collection of samplings from different components has different clinical importance. Along with the popular nasal swabs and throat swabs, sputum, blood as well as rectal swabs；

Nasal and throat swabs – upper respiratory tract specimens

Sputum – Lower Respiratory Tract Specimens ( Saliva Collection Kits )

Anal swab – digestive tract specimen

Blood – Antibody Test Specimen

The distinction between both is a positive nucleic acid shows the presence of viral nucleic acid in the sampling. Which suggests that the infected individual might be infectious. A favourable IgM antibody shows that the patient remains at the beginning of infection. IgG antibodies indicated that the patient had SARS-CoV-2. However, we were unable to determine whether it was transmissible. Compared with antibody detection, PCR nucleic acid discovery is much more sensitive and is additionally the “gold criterion” for laboratory detection.

Therefore, in recent cases, doctors discussed that the patient has symptoms of infection.

What factors may affect COVID-19 nucleic acid test results?

1. Viral load: In summary, when the viral lots are low. False negatives may occur.

2. The coronavirus may alter, which may further impact the accuracy of the test in the future.

3. Testing method: In the recently reported genuine tasting scene, several participants reported that the swab only revolved left and right in the mouth, and it really felt like it was only touching saliva.

However, did not reach the lingual and palatal arc, and the respondents did not have nausea and also reflexes. Sex-related security action, this type of tasting has a high possibility of not gathering exfoliated cells of the respiratory tract, so it is vulnerable to missed discovery, leading to false unfavourable results.
