Flu Test Throat Swab China Factory And Manufacturers

Posted on 2022年5月26日2022年5月26日 by Dr. Lee

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

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.

Sampling for COVID-19 Testing: Introduction to Nasal Swabs, Pharyngeal Swabs, Nasopharyngeal Swabs

1. Material introduction:

1. Flocked swab: It is made of nylon fibre crowding modern technology, and also the front end is coated with nylon brief fibres repaired in a vertical manner so that there is no absorption hole in the whole tasting area of the tasting swab. As well as the sampling example, will certainly not be scattered as well as preserved in the fibers. Which promotes much faster and also a lot more efficient elution. Traditional cotton swabs can not entirely collect and also elute samples, while flocked swabs can elute 95% of examples. widely used.

Flocked Respiratory Collection Iclean Nylon Tip Swab Test

2. Cotton Swab: The cotton bud is made from sterilized cotton wrapped around a wooden stick or a plastic pole. Because the all-natural product of cotton has a reduced release rate to the example, and also several of the natural fatty acids in it will harm microbes, the, even more, are much less as well as much less used for sample collection.

3. Rayon Head Swab: Rayon is a synthetic fiber made from wood pulp. Although categorized as an artificial fibre, it is basically a natural material. It is often the standard for diagnostic testing.

4. Polyester Fibre Head Swab: The head product of the polyester fiber swab is made from polyester long fiber winding, which was very first presented in the field of medical screening by DuPont. Polyester fibres for microbial collection, rapid diagnostics, and also PCR screening. Swabs have a high launch price yet are extra expensive than cotton and also rayon swabs.

5. Foam Tip Swabs: Swabs made of medical quality polyurethane are superb materials for diagnosis, especially for cell sampling. This product has great absorption of hydrophilic substances and inadequate absorption of hydrophobic compounds. For some circumstances that need resistance to chemical rust, and also for DNA as well as microbial testing.

2. Introduction of sampling site:

Nasal Swab: Sampling of the nasal cavity.

Throat swab: Sampling of the throat area.

Nasopharyngeal swab: Sampling from the nasal cavity to the throat.

3. Safety factor and material:

Ordinary people can operate it. The new crown self-test products on the market generally use nasal swabs, and Foam Tip fibre heads are the first choice.

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

Professionals must operate it, and it needs to be very careful from the nose to the throat. Generally, Westerners are easier to accept, while Orientals are less acceptable.

Viral Transport Media Kit

Innovative jet embedded nylon modern technology can improve the effectiveness of the example collection from the client to the largest degree. 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.

Enlarged view of flocked swab

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.

Combined Throat And Nose Swab

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

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

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

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

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

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

COVID-19: Will The Pandemic End in 2022?

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

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

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

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

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

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

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

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

Sterile Flocked Swab

Oropharyngeal swab

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

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

Nasopharyngeal swab

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

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

Who is not suitable for nasal swab

What is A Covid-19 NP Swab?

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

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

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

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

How to overcome the discomfort of throat swab

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

Recommended to relax before collecting specimens.

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

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

Flocked Swab With Vtm Kits Leading China Manufacturer

What are flocked swabs used for?

Flocked swabs are widely used in Covid Test bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic-based tests, and forensic identification. Both are ideal.

For throat sampling of respiratory viruses such as influenza, swine flu, bird flu, hand, foot and mouth.

Vtm Kits are used for the collection, transportation and storage of influenza, avian influenza, coronavirus and other virus samples for subsequent extraction and PCR amplification.

After samplers collect virus samples, they usually do not conduct PCR testing at the sample collection site in time.

So the collected virus flocking swab samples need to be transported. The virus itself will rapidly decompose in vitro, affecting subsequent detection. During transport, we need to add a virus preservation solution (virus transport medium).

For different detection purposes, we need to use different virus preservation solutions.

At present, it mainly includes inactivated type and non-inactivated type. In order to meet different detection requirements and different laboratory conditions for virus detection, it is very necessary to use different preservation solutions.

Sterile Flocked Nasopharyngeal Swab, 100% nylon flocked swab that provides exceptional absorption quality.

The principle of flocking swab precipitation.

1. Through the directional friction effect of the fiber layer of the flocked swab, the laboratory operator can complete the cell sample.

The unique structure of the top of this swab can greatly increase the number of samples collected

2. Flocked Swab is ideal for collecting large amounts of cells & rapid elution of the specimens instantly released into the transport medium.

More than 95% sample release rate. Very easy to elute.

3. The capillary movement between the nylon fibres at the top of the flocking swab forms a strong hydraulic pressure for absorbing liquid or cell-like samples.

Why flocked swabs are more beneficial for micro DNA collection.

1. The top of the traditional cotton swab, may even lead to false-negative results of the test.

2. The top of the flocking swab has a unique structure, which can almost completely extract and separate trace DNA, so the flocking swab has more obvious advantages in collecting trace DNA.

Made of non-inhibitory DNA amplification materials. It has been verified that it can be directly amplified by PCR, eliminating the need for extraction steps.

About viral transport media

At present, it mainly includes two types: inactivated and non-inactivated.

Flocked Swab With Vtm Kits Leading China Manufacturer

Inactivated preservation solution:

It can lyse and inactivate the virus in the sample so that the virus loses its infectious activity.

It can effectively prevent the secondary infection of operators.

But it also contains inhibitors, which can protect the viral nucleic acid from degradation.

Therefore, the experimenter can perform follow-up detection by NT-PCR.

Stored at room temperature for a long time, saving the storage and transportation costs of virus samples.

Non-inactivated preservation solution:

The non-inactivated preservation solution of the present invention can maintain the in vitro activity of the virus and the integrity of the antigen and nucleic acid, protect the viral protein shell, and maintain the originality of the virus sample to a large extent.

Not only for nucleic acid extraction and detection (PCR test) but also for virus culture and isolation.
