The benefits of flocked swabs for COVID-19 viral collection.

1. Sample collection process: The unique structure of the front end of the flocking swab can greatly increase the number of samples collected.

2. Sample dissolution process: The brush-like layer structure can release almost all collected samples. There are more advantages for the collection of trace DNA.

3. According to different analysis items, the corresponding soft or brush texture swabs have reached the maximum collection.

4. Disposable sterile sampling swab rod with breaking point.Learn more

5. Flocked swab technology improves the adsorption/release of samples and the sensitivity of the analysis.

6. The front flocked swab sampling is more precise and suitable for extracting more cells from the nasopharynx.

7. Packed in a transparent plastic tube to avoid biological pollution.

In short, the upright nylon fibre is like a soft brush, which can collect more cell samples. The capillary action between nylon fibers enhances the load of aqueous samples, and the samples are concentrated on the surface of the swab, which is easier to elute. Nylon flocking swab can absorb and release more samples.

COVID-19 Pooled Sample Testing:Improve sampling rate and reduce cost.

With the advent of autumn and winter, the possibility of a new outbreak of COVID-19 is increasing.

COVID-19’s large-scale community screening is the main means to cope with the recent outbreak of small-scale epidemics at home and abroad.

At present, New Coronavirus’s mixed sample nucleic acid detection has become a routine method to effectively enhance the screening and detection of nucleic acid in community population.

The pooled sample test of covid-19 increase the sampling rate and meet the growing needs of low-risk populations.

Virus transport medium,disposable virus sampling tube

What is a Pooled Sample Test?

“mixed detection”, that is, nucleic acid test of Pooled Sample.

On the one hand,it is a method to sample several people, such as 3 or 5 or even 10, and then put them into the same virus sampling tube.

On the other hand,pooled Sample means combining the same type of specimen from several people and conducting one NAAT laboratory test on the combined pool of specimens to detect SARS-CoV-2.

What is the significance of nucleic acid test in Pooled Sample?

COVID-19 Pooled Sample Testing Advantages

Because a virus sampling tube only puts one person’s sample, the cost will be very high, and the detection time is long, which is not suitable for large-scale nucleic acid detection.

In principle, the single sample sampling mode is only applicable to high-risk areas and key populations.

In order to improve sampling efficiency, shorten sampling time and reduce sampling cost. Multi Country selection of Pooled sample test scheme.

For example, when 5-in-1 mixed sampling test is used, the result is negative, which means that all five people are negative.

On the contrary, once positive or weak positive is found, it will be traced immediately.

Re collect single tube swabs for review, and then determine which of the 5 people is positive.

Therefore, the cost of 5-in-1 mixed mining is relatively low.

This also caused the 5-in-1 mixed sampling mode to be five times faster than the previous mode of using a virus sampling tube for a human sample.

One of the biggest disadvantages of sample merging is the decrease of associated test sensitivity.

Analyzing multiple samples in a single reaction effectively improves the flux, but it also dilutes a single sample and may reduce the weak positive signal from outside the detection limit.

In short, pooled sample testing is mainly used for large-scale screening to check asymptomatic coronavirus infected persons. It is suitable for large-scale testing projects such as schools, factories, units and urban areas. It has the advantages of efficient screening and resource saving.

Although reduced detection sensitivity is acceptable for screening services in asymptomatic populations.

However, When providing diagnosis for high-risk or symptomatic patients, we must give priority to the accuracy of the results.

The special preservation tube for Pooled Sample test uses medical grade PP as raw material, unique structural design and manufacturing process to prevent liquid leakage. And has the characteristics of high temperature resistance, high pressure resistance and high-speed centrifugation resistance.

Cell medical (Dongguan) Co., Ltd. produces virus sampling tubes of various specifications, both inactivated and non inactivated, disposable virus sampling tubes, pooled sample sampling tubes.
such as 1ml, 2ml, 3ml, 5ml, 10ml and other specifications.

Nasal swab for flu,Rapid antigen nasal or throat swab

Posted on 2021年9月8日2022年3月22日 by Dr. Lee

Nasal swab for flu_Rapid antigen (nasal or throat swab) test

Influenza is common in winter and spring. The clinical manifestations are mainly systemic poisoning symptoms such as high fever, fatigue, headache, cough and systemic muscle pain, while the respiratory symptoms are mild.

Influenza viruses are prone to mutation, infectious, susceptible to population and high incidence rate. They have caused many outbreaks in the world, and are important public health issues worldwide.

Why should we detect and prevent influenza?

According to the World Health Organization (WHO), seasonal influenza can cause 3-5 million severe cases and 290000-650000 deaths worldwide every year.

The researchers believe that children under the age of 5 are at high risk of severe influenza, but children under the age of 2 are at the highest risk, and infants under 6 months have the highest hospitalization rate and mortality.

Pregnant women, infants, the elderly, patients with chronic basic diseases and other high-risk groups have a higher risk of serious diseases and death after suffering from influenza.

Nasal swab for flu : common influenza test method

Nasopharyngeal sample collection

Influenza is an acute inflammation of the respiratory tract caused by the patient’s infection with influenza virus. The patient can have a series of symptoms such as cough, expectoration, fever, sore throat, stuffy nose, runny nose and general fatigue. In case of influenza, we should conduct relevant examinations in time to further clarify the diagnosis, including the following tests:

First, blood routine test, patients with influenza can promote the increase of lymphocytes. If combined with bacterial infection, there can be the increase of leukocytes and so on.

Second, scientists can culture throat swabs of influenza viruses. In throat swab culture, researchers can detect the related virus.

Third, influenza patients can do second-generation sequencing, including sputum second-generation sequencing, which can determine the type of virus infected.

Fourth, influenza patients can do the detection of respiratory pathogens to further clarify the pathogens of infection.

At present, the two most common influenza tests are rapid antigen diagnostic test and influenza virus cell culture test. Both tests rely on Nasopharyngeal swabs, pharyngeal swabs, etc. for virus sampling. The most commonly used sampling swab is nylon flocking swab.

Nasal swab for flu:Application

It is suitable for the detection and sampling of COVID-19, influenza virus , hand foot mouth disease virus, COVID-19, measles rubella and other types of viruses.

About nasal swab sampling

Why use flocked nylon swabs?

flocked swabs_Cell medical (Dongguan) Co., Ltd.

Flocked nylon swab: excellent sample collection / release ability, release rate > 90%.

Conventional fiber swab: the sample is intercepted by the gap in the fiber mass. That is, the sample is penetrated, diluted and intercepted in the fiber. Acquisition is slow and release is slower.

The sampling time of flocked swab is 3-5 seconds, while that of traditional swab is 15-120 seconds or even longer.

This caused pressure on the staff during the diagnosis process. Only by extracting samples faster can we complete the collection and analysis more efficiently.

Precautions for patients with nasopharyngeal swab:

① Please do not take antibiotics a few days before making nasal swabs;

② Do not use disinfectant mouthwash or smear the focus a few hours before nasal swab.

③ Do not eat, smoke or drink a few hours before doing nose swab.

Precautions for Sampler:

① . the sampler shall stand on the side of the patient for sampling.

② The patient is required to pull down the mask to expose only his nostrils. In case of sneezing reflex, the patient can cover it with elbows or paper towels.

If the sampler is not directly in front of the patient, the exposure risk will be lower.

③ If the patient’s turbinate is hypertrophic, the nasal tract is narrow, and the insertion of the nasal swab feels resistance. Try to change one side of the nasal cavity or directly change to oropharyngeal swab collection.

④ Those with nasal allergy symptoms are easy to induce sneezing. It is recommended to take oropharyngeal swab samples.

⑤ Remember to wear a protective mask / screen. For individuals who are highly suspected or basically diagnosed, or who have severe cough and hiccup, they should put on protective clothing.

⑥ After sampling, replace gloves, disinfect hands, and spray disinfectant where patients have touched.

Finally, we should pay attention to nasal swab for flu in special times. Remember to wear masks and personal hygiene when going out. Once you find the virus, please isolate it to avoid re transmission.

Nasal swab pcr test

Posted on 2021年9月7日2021年12月21日 by Dr. Lee

Nasal swab pcr test COVID-19 Antigen Rapid Test Kit

Detection of COVID-19 by nasal swab PCR is an accurate and reliable method. Positive detection means you may have SARS-CoV-2. Negative detection means you may not have SARS-CoV-2 when testing.

In order to ensure your safety, if you have symptoms of COVID-19. Or people who have been exposed to the virus and tested positive should be tested.

What is the symptom of COVID-19?

If you have the following symptoms,if you have the following symptoms, please buy covid-19 antigen rapid test kit immediately or go to a nearby hospital for PCR test.

1.Fever;

2.General fatigue;

3.cough;

4.Dyspnea or even respiratory failure；

5.Nausea;

6.vomiting;

7.abdominal pain;

8.diarrhea;

Symptoms of New Coronavirus pneumonia are not necessarily typical, and some patients may not have clinical manifestations at the early stage of New Coronavirus infection. Then clinical manifestations will appear, that is, “asymptomatic infection” in incubation period.

In other words, try to avoid activities in places with crowd gathering, closed space and poor ventilation.

What is nasal swab PCR test？

Polymerase chain reaction (PCR) uses a piece of DNA as a template. Then, with the participation of DNA polymerase and nucleotide substrate, the DNA was amplified to a sufficient number for structural and functional analysis.

Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate until COVID-19(if present) is detected.

What should we pay attention to before doing nucleic acid test？

1.Try not to eat 2 hours before sampling to avoid vomiting.

2. Do not smoke, drink, drink water or chew gum 30 minutes before sampling.

3. The tester needs to wear a mask correctly and remove the mask before testing;

4. Wear it immediately after testing, and prepare a spare mask for easy replacement at any time after pollution.

5.When you feel sour and itchy in your nose or sneeze, you can immediately cover it with a paper towel or elbow.

Before collecting nasopharyngeal swabs and before being tested, the collection personnel shall be informed whether they have relevant past medical history. For example, history of nasal surgery, history of deviation of nasal septum, blood diseases, throat diseases, etc

How long will we know the pcr test results？

The test results of sampling in the morning are generally available from 18:00 to 19:00.

The detection results of afternoon sampling can generally be queried around 22:00.

What’s the difference between the PCR and antigen tests for COVID-19?

Polymerase chain reaction (PCR): PCR is the most reliable and accurate method to detect active infection. PCR tests usually give results in a few hours.

Antigen detection: detect protein fragments on the surface of covid-19. Antigen detection usually takes only 15 to 30 minutes.

How can we prevent COVID-19?

Firstly, keep good personal hygiene habits, wear masks when going out, wash hands frequently, clean the room, and wipe the floor and other furniture with disinfectant. Second, disinfect your hands with 75% alcohol every time you go out and go home, reduce the number of times you go out, and wear qualified masks. And the diet should also be light, do a good job of physical exercise and enhance personal physique.

Most importantly, if our conditions permit, we should vaccinate and conduct multiple nucleic acid tests.

If our Nasal swab pcr test results are positive,what should we do?

If our test results are positive, don’t be afraid. We should wear masks and go to the nearby Hospital for follow-up in time.

Repeat the nucleic acid test.Don’t be afraid and hide the test results. Timely medical treatment is the best choice.

Flocked swab using spray dense planting nylon fiber technology;The volume of samples collected and released is 3 times higher than that of traditional swabs. Ensure the survival rate of cell samples, no residual fatty acids, and will not affect the test results.

Picture of sampling flocking swab

Why use flocked swabs？

COVID-19 is New Coronavirus’s variant coronavirus, which can cause pneumonia after human infection. It belongs to an acute respiratory infectious disease, which is highly infectious and generally susceptible to people. It is easy to replicate in the upper respiratory tract of human body. In general, new crown nucleic acids are detected rapidly within 96 hours after infection. Testers can find viruses in the human upper respiratory tract. Experiments show that flocking swab can quickly elute > 95% of the original samples, and easily improve the detection sensitivity.

Application of sampling flocked swabs.

The upper respiratory tract of the human body includes the nasal cavity, pharynx and throat. That is to say, if a person is infected with COVID-19, he can extract the nucleic acid of the virus in the nasal cavity, pharynx and larynx in 96 hours. Therefore, we generally sample these locations when we carry out the rapid detection of new crown nucleic acid.

we distinguish swabs by different sampling positions. For nasal sampling, we become nasopharyngeal flocked swabs; For oral sampling, we become oropharyngeal flocked swabs.

What is the difference between nasopharyngeal swabs and oropharyngeal flocked swabs?

Nasopharyngeal swabs and oropharyngeal swabs differ in material hardness in addition to the differences in sampling sites. The nasopharyngeal swab is generally slender and soft, and can change its shape along the nasal cavity, which is convenient for the sampling personnel to probe into the upper respiratory tract along the nasal cavity. The oropharyngeal swab will be thick and hard.

In terms of comfort, there are also great differences between the two. Since gas exchange is often carried out in the nasal cavity, the swab shall be fully extended to the end of the nasal cavity during sampling to ensure that sufficient concentration of samples are collected. This usually brings very uncomfortable feeling to the subject, and sometimes even leads to epistaxis.The oropharyngeal swab only needs to collect the pharyngeal sample, and only needs the person to open his mouth for collection. Although it occasionally causes a temporary feeling of nausea, the discomfort will not last too long.

There are also obvious differences between the two in drug loading. Studies have shown that in patients infected with the new crown virus, the amount of drug carried on the nasopharyngeal swab is significantly higher than that on the oropharyngeal swab. In other words, the detection amount of nasopharyngeal swabs is generally higher than that of oropharyngeal swabs.

In addition to nasopharyngeal flocked swabs and oropharyngeal swabs, there are anal swabs. As the name suggests, anal swab is a kind of test for patients with gastrointestinal symptoms. It can effectively improve the detection rate, but it is not widely used because of the inconvenience of sampling.

Attention

After sampling the flocking swab, we should immediately put the swab into the storage tube to avoid polluting the sample. Then, the subsequent rapid detection process of new crown nucleic acid was carried out. No matter what kind of swab is used, the process of rapid detection of new crown nucleic acid is the same. The rapid detection of new crown nucleic acid was completed in four independent areas of the laboratory, and the test results were obtained.

how to collect nasopharyngeal swab?

After several times of nucleic acid sampling and testing, citizens wondered: why do some people require nasopharynx swabs and some people can collect oropharyngeal swabs? Today, experts from cell medical will explain to you.

What is a sampling swab?

At present, except for special diseases, COVID-19’s nasopharyngeal swabs and oropharyngeal swabs are the most common ways of collecting.

Studies have shown that nasopharyngeal swabs have higher detection rate of COVID-19 nucleic acids than oropharyngeal swabs. Because the nasopharyngeal cavity is relatively closed and the virus is easier to accumulate. However, whether it is oropharyngeal swab or nasopharyngeal swab, the key is that the collection action must be standardized, in place and meet the standards. As long as the acquisition is standardized, both methods can achieve the expected detection purpose.

How to collect a nasopharyngeal swab?

nasal swab collection method_How to collect a nasopharyngeal swab？

1. The patient’s head tilts back (about 70 degrees) and persists. 2. Use a swab to estimate the interval from the ear root to the nostril. 3. Insert from the nostril pen to the face. The deepening interval should be at least half of the length from the earlobe to the tip of the nose. Reach the posterior nasopharynx after encountering resistance, stay for several seconds to absorb secretions (generally 15 ~ 30s), and rotate the swab for 3 ~ 5 times. 4. The swab should be gently rotated and taken out, and the swab head should be immersed in a collection tube containing 2ml lysate or cell preservation solution containing RNase inhibitor. 5. Break the sterile swab rod at the top, discard the tail, tighten the tube cover and close it with sealing film.

oropharyngeal swab collection

collection method of oral swabs

1. Ask the patient to gargle with normal saline or clear water first.

2. Wet the flocked swab in sterile normal saline.

3. The patient sat down with his head tilted back and his mouth open, accompanied by an “ah” sound.

4. Fix the tongue with a tongue depressor, and the swab jumps over the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.

5. The bilateral pharyngeal tonsils should be swabbed back and forth with moderate force for at least 3 times, and then the posterior pharyngeal wall should be swabbed for at least 3 times, 3 ~ 5 times.

6. Remove the swab to prevent touching the tongue, pituitary, oral mucosa and saliva.

7. Immerse the swab head into the preservation solution containing 2 ~ 3ml virus.

8. Break the sterile swab rod near the top, discard the tail, tighten the tube cover and close it with sealing film.
