What’s the use of a flocked nose swab？

Nasal swab detection is a kind of nucleic acid detection, which is used to detect the presence of viral nucleic acid in the body. So as to determine whether the human body infected with COVID-19.

Nasal swab detection requires collecting cells deep in the throat of the tested person and placing them in a Petri dish for observation. Because New Coronavirus is mainly transmitted through the respiratory tract,if the human body is infected with COVID-19, there will be a lot of viruses in the throat. Therefore, it is a more accurate way to detect the existence of COVID-19 by detecting the cells in the throat.

What is the method of mini nasal swab collection?

① Please keep the patient’s head still and remove the secretions on the surface of the anterior nostril;

② use a flocked swab or other tools to the distance from the nostril to the root of the ear and mark it with your fingers;

③ insert the swab gently and slowly through the nasal cavity;

④ swab until the finger mark or stay for several seconds after encountering resistance to absorb secretions; (generally stay for 15-30 seconds, and then rotate gently for 3 times);

⑤ gently rotate the swab and put it into the virus sampling tube (transport medium); Break the swab tail rod along the breaking point and place it completely in the tube. Tighten the pipe cover.

⑥ If you need to collect from two nostrils, you should use another swab.

⑦ Send to the inspection room for inspection as soon as possible.

⑧ Note the information of the collected person to avoid confusion.

Comparison of advantages of various testing methods of COVID-19

Posted on 2021年9月14日2021年9月15日 by Dr. Lee

advantages of various testing methods

The detection methods of COVID-19 mainly include nucleic acid detection, antibody detection and antigen detection. Due to the low detection rate of antigen, the SARS-CoV-2 detection mainly focuses on antibody and nucleic acid detection. Nucleic acid detection has the characteristics of early diagnosis, high sensitivity and specificity; However, antibody detection is convenient and rapid, which can be used as a supplementary means of nucleic acid diagnosis. Due to the limitations of “false positive” and “false negative” antibody detection, it is not suitable for general population screening such as returning to work, and school, nor for epidemiological investigation in low epidemic areas.

NAT Detection process

The detection procedure needs to go through five steps: sampling, sample retention, preservation, nucleic acid extraction and computer detection.

First, collect samples according to the instructions of the kit. The sample types include pharyngeal swab, nasal swab, sputum, bronchial lavage fluid, alveolar lavage fluid, etc.

Because RNA is easy to degrade, flocked swabs without RNase and storage tubes without RNase are used when collecting samples.

After obtaining the patient’s sample, it needs to be tested as soon as possible. If it cannot be tested immediately, it needs to be packaged at low temperature and sent to a special testing institution for testing.

After receiving the sample, the testing institution shall extract the nucleic acid from the sample. The nucleic acid extraction reagent shall use the nucleic acid extraction kit specified in the approved product manual.

Finally, fluorescence PCR nucleic acid detection, that is, machine detection. It takes 70-80 minutes to amplify the extract by fluorescence PCR.

Sample collection, oropharyngeal swab or nasopharyngeal swab

NAT Detection process Nucleic Acid Testing

Antibody detection

After the virus invades the human body, the human body will produce corresponding specific antibodies for defense.

According to different molecular structures and antigen specificity, scientists divide immunoglobulins into five categories: IgG, IgA, IgM, IgD and IgE.

After the antigen enters the human body for the first time, plasma cells secrete antibodies after a certain incubation period. IgM first appeared, but the antibody had short maintenance time, low concentration and low affinity. It lasted for several days to several weeks in the blood. It was a diagnostic index of acute infection; When IgM is about to disappear, the content of IgG reaches the peak. IgG appeared late, but its concentration was high, its maintenance time was long and its affinity was high. The positive serum IgG indicates the middle and late stage of infection or previous infection. But the antibody content increases rapidly in the short term, which may be several times to dozens of times higher than the original antibody content. It is mainly IgG, which lasts a long time in the body, and IgM rarely increases.

In this epidemic, the researchers studied patients with covid-19 and found that after the virus invades the human body, IgM antibody takes about 5-7 days to produce and IgG antibody takes 10-15 days to produce.

Antibody detection kits-advantages of various testing methods

Comparison of advantages and disadvantages of two different detection methods

Compared with the serological detection of antibodies, Nucleic Acid Testing can detect patients in the window stage.

Early detection of infected persons is the “gold standard” for COVID-19 detection, but it requires higher detection equipment or platform.

The high sensitivity RT-PCR instrument is expensive, and the laboratory cleanliness and operator requirements are higher. In addition, nucleic acid detection takes a long time. Considering the sample transportation and sample backlog, the results can be reported as soon as 24 hours.

Compared with nucleic acid detection, blood samples detected by antibody serology are easier to obtain. If the RNA of the virus detected by nucleic acid is the direct evidence of the existence of the virus, the antibody detection is the antibody stimulated in the patient’s blood, which is indirect evidence and has a suggestive effect on the clinic.

When nucleic acid detection is negative, adding IgM and IgG antibody detection can make up for the shortcoming that nucleic acid detection is easy to cause missed diagnosis.

Is anal swab nucleic acid test more accurate than nasopharyngeal swab?

Posted on 2021年9月13日2021年9月13日 by Dr. Lee

Is anal swab nucleic acid test more accurate than nasopharyngeal swab?

Nucleic acid detection:generally carried out by sampling pharyngeal swabs in the nasal cavity and oral cavity.

Now began to increase the anal swab test, we are also curious about this test method. So, is anal swab nucleic acid detection more accurate than nasopharyngeal swab? How to sample for anal swab test?

Is the nucleic acid detection of anal swab more accurate than that of nasopharyngeal swab?

In the screening of New Coronavirus pneumonia, we mainly used the oropharyngeal swab nucleic acid test. Because the reason is convenient and quick, suitable for large-scale screening. The accuracy of nasopharynx swab for new crown nucleic acid detection is higher than that of oropharyngeal swab, but the human body feels uncomfortable.

In last year’s test, researchers found that many infected people had negative pharyngeal nucleic acid.But their anal swabs were still positive for longer.

The combination of the two in nucleic acid detection can improve the detection rate and reduce the proportion of missed diagnosis.

However, anal swab sampling is inconvenient and not suitable for large-scale screening and testing in the community.

For some asymptomatic or mild infections, the condition recovers quickly after infection. And the pharyngeal nucleic acid may not be detected in 3 to 5 days.

The researchers found that the duration of nucleic acid positive in feces or anal swabs of some infected people was longer than that in the upper respiratory tract.

Therefore, increasing anal swab nucleic acid detection can improve the detection rate of infected patients and reduce missed diagnosis.

Although nucleic acid detection has the advantages of high sensitivity and short detection cycle, it also has some disadvantages.

Different from the direct isolation of live virus from human body, nucleic acid detection adopts an indirect method, which may cause false negative.

Anal swab & test tubes

How to sample for anal swab test

1. Soak the swab in normal saline, insert it into the anus of 2-3 cm, wipe it from the folds around the anus, or rotate it gently in the anus. And then insert it into the test tube containing normal saline.

2. For fecal swab culture, all the above operations require the use of sterile equipment and the swab into a sterile test tube.

What is genetic testing?

Posted on 2021年9月9日2021年9月9日 by Dr. Lee

What is genetic testing?

Definition of gene

What we usually call genes is a collection of genes in human cells, called the genome.

Every cell in our body has a complete genome. Inherited from parents and passed on to children.

Genes make people different from animals, make families different from families, and brothers and sisters are similar but different.

These subtle differences often do not exceed 0.5% of genes.

But determine different appearance, personality, genetic characteristics, and our adaptation to the external environment.

Why genetic testing?

It must be noted that various human traits and diseases are the result of the joint action of genes and environment .

Genes only play a partial role in traits, and whether gene expression is also greatly affected by the internal and external environment.

Therefore, gene test reports can not be directly used as the basis for clinical treatment, and it is not advisable to judge the role of genes without individual environment.

On this premise, the gene test report still has a certain reference significance for understanding various characteristics of the human body.

Understand that they carry hereditary pathogenic genes

We can know whether we carry pathogenic genes through genetic testing. For example, people with a family history of genetic diseases, cancer and hypertension. According to the test results, adjust dietary health care and living habits to avoid the occurrence of diseases. If both pregnant couples carry the pathogenic gene of recessive disease at the same time. They can pay attention and conduct further investigation when preparing for delivery.

Select drugs correctly to avoid drug waste and adverse drug reactions

Due to genetic differences, individuals will respond differently to drugs. When taking the same kind of drugs, some people will feel very effective, while others will not only be ineffective, but also have toxic and side effects. When some people use certain drugs, they may also have drug allergy. Through gene testing, we can know everyone’s gene situation, which may play a guiding role in drug use to a certain extent. Again, the drug test report can not be directly used in clinic. The drug selection and use in the treatment of diseases need to follow the doctor’s advice.

Provide scientific health management

Many adverse environmental factors and bad living habits will make the human body more prone to diseases. People can understand the occurrence tendency of individuals in different diseases through genetic testing, and make corresponding life adjustment or intervention in order to reduce the risk and delay the occurrence of diseases.

What is the principle of gene testing?

To understand the principle of gene detection, we need to understand the following questions:

Reasons for gene testing

Each person’s human nucleus has 23 pairs of chromosomes, which are composed of DNA and ribosomal proteins. All chromosomes have 3.16 billion base pairs.

When the same base pair position changes (this situation is generally called single nucleotide polymorphism, or SNP), which has a certain impact on human genetics and health, this SNP is the locus in the gene report. At present, there are nearly more than 100 million known or named SNPs. Most of the differences between human DNA are SNP differences, which is about 0.5% of the total base pairs of human DNA. A large part of gene detection is based on SNP.

Samples for genetic testing

Normal human samples required for gene testing include saliva sampling and blood sampling. For different examination items, excreta sampling and cell slice sampling are also included.

Methods of gene testing

There are several ways to measure related base pair differences (SNPs): PCR, chip, exon, and genome-wide. The number of SNPs detected is dozens, hundreds of thousands, tens of thousands, and all SNPs.

Disposable DNA sampling flocked swab

2. It can quickly absorb a small amount of samples and has high release aging rate.

3. The front end is sharp enough to extract cells from the victim or suspect’s fingernails.

4. The swab has a breakpoint, which is convenient for the automatic extraction workstation to extract samples.

5. The whole swab is packed in a transparent plastic tube to avoid biological pollution.

Who can do genetic testing?

① People with family disease history;

② People with bad living habits;

③ People exposed to chemical pollution, heavy metal pollution, nuclear pollution and toxic and harmful substances for a long time;

④ Friends who pay attention to health;

Hello!

When many diseases are diagnosed, it’s too late. Do a good job in disease prevention to make us healthy for a longer time!

COVID-19 Testing: Method of collecting virus swab samples

Posted on 2021年9月9日2021年9月17日 by Dr. Lee

COVID-19 Testing: virus swab

According to New Coronavirus’s pneumonia diagnosis and treatment plan (trial version fourth), to diagnose suspected cases of New Coronavirus pneumonia, we need one of the following etiological evidence:

1. Respiratory tract specimens or blood samples were detected by real-time fluorescence RT-PCR for New Coronavirus nucleic acid positive.

2. Novel coronavirus is highly homologous to respiratory tract specimens or blood samples.

Therefore, novel coronavirus pneumonia is an indispensable part of the specimen collection. So, where to collect specimens? How to collect specimens? How can medical staff protect themselves during collection? What should I do after collection?

How to obtain a virus swab specimen?

We all know that the collection method of virus swab specimen is basically to use the swab to sample the infected place or part of the virus, and then put it into the virus sampling tube containing preservation solution without touching other places, so as to conduct virus detection later.

Specimen type:

1. Upper respiratory tract specimens: including pharyngeal swab, nasal swab, nasopharyngeal extract, etc.

2. Lower respiratory tract specimens: including deep expectoration fluid, respiratory tract extract, bronchial lavage fluid, alveolar lavage fluid and lung tissue biopsy specimens.

3. Blood samples: try to collect anticoagulants in the acute stage within 7 days after onset. The collection volume is 5 ml, preferably fasting blood.

4. Serum samples: try to collect double serum in acute stage and recovery stage.

5. Conjunctival specimens: conjunctival swab specimens shall be collected for cases with ocular infection symptoms.

6. Stool samples: Patients with diarrhea symptoms need to collect stool samples.

COVID-19 Testing: Common virus swab sampling methods

Methods of throat swab collection

Inform the patient of the purpose of examination, collection method and collection time. It is best to collect specimens before using antibiotics.

Objective: To study the clinical effect of the method

Secretions were collected from pharynx or tonsil for bacterial culture or virus isolation to assist in clinical diagnosis and treatment.

Prepare sampling supplies:

Disposable sampling swab, virus sampling tube, tongue depressor and biological bag

Operation method:

(1) Ask the patient to sit down, tilt his head back, open his mouth and make a “ah ~” sound

(2) The sampling personnel shall fix the patient’s tongue with a tongue depressor, and use a disposable pharyngeal swab to pass through the root of the tongue to the posterior pharyngeal wall, tonsil recess and lateral wall;

(3) Repeatedly wipe 3-5 times to collect mucous membrane cells or sputum

(4) . gently remove the swab to avoid touching the tongue, the suspension, the oral mucosa and saliva

(5) Put the swab into the virus sampling tube gently and vertically. The sampling personnel shall disconnect the tail of the flocking swab and leave the tail of the swab completely in the tube.Be careful that the swab does not touch the wall of the tube.

(6) . tighten the cap, mark it, and seal it in the biosafety bag.

(7) The sampling personnel shall send the samples to the laboratory for testing in time. If the sampling personnel cannot send the samples for inspection in time, they shall store them at low temperature

Methods: nasal swabs were collected

Nasopharyngeal swab_COVID-19 Testing: Method of collecting virus swab samples

(1) Ask the patient to sit down with his head slightly back and remove the secretion from the front nostril first;

(2)measure the distance from nostril to ear base with swab and mark with finger

(3)gently insert the swab into the nostril until it is marked or stopped when there is obstruction. Let the swab stay in the nose for 15-30 seconds, and then rotate it gently three times.

(4) slowly pull out the nasal swab and quickly put it into the virus sampling tube. Then break the swab, leave its tail and place it completely in the tube.

(5) tighten the cap, mark it, and seal it in the biosafety bag.

(6) If we need to collect from both nostrils, we should use a swab.

(7) It should be sent to the laboratory for testing in time. If it can not be sent for inspection in time, it should be stored at low temperature.

Generally speaking, COVID-19 testing: the main methods of collecting virus swabs are nasopharyngeal sampling and oropharyngeal sampling.

Is COVID-19 pneumonia more infectious than SARS?

The effectiveness of infectious disease transmission depends on its basic regeneration index. Novel coronavirus pneumonia is more infectious than SARS at present, with a basic regeneration index of SARS higher than that of SARS.

The novel coronavirus pneumonia is a new disease, and the population is generally immune. Everyone is susceptible and susceptible to infection. The incubation period of COVID-19 also has the ability to transmit, and it has longer infection time. The novel coronavirus pneumonia novel coronavirus pneumonia is also typical of the clinical symptoms, and asymptomatic infections are also contagious, so the infection of new crown pneumonia is higher than SARS.

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.

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.
