With repeated epidemics, nucleic acid testing and throat swabs seem to have become part of our lives. We also all know where to go for nucleic acid testing, but what actually happens during a swab test? What are the tests for COVID-19? If you haven’t done nucleic acid testing, you may wish to read this article first. This article will popularize five things about Oral Swab testing.

On this page, you will learn:

What are the tests for COVID-19?

What are the tests for COVID-19?

Oral swabs and nasal swabs or saliva. In the experiments, oral flocked swabs were used to collect samples from the oral cavity for the oral examination.

This is different from a saliva test, which spits saliva into a small container.

COVID-19 Test, there are usually two main types of tests:

There are two main methods of nucleic acid detection: acid detection reagents and antibody detection. The first method is usually PCR detection through throat swabs, gene amplification, and then nucleic acid detection.

The antibody test is to choose blood, the method of blood draw to see the results, to observe whether the antibody titer increases.

How to do a mouth swab for COVID-19?

1. Rinse your mouth with water 30 minutes in advance (no toothpaste, especially breastfed babies need to drink a few mouthfuls of water, and no mouthwash);

2. Mark the envelope with a pen (eg: father, mother or child) and date of collection, name.

3. Hold the CellMedical flocked sampling cotton swab in one hand, put it into the left (right) inner buccal mucosa of the mouth and wipe it repeatedly for 15-20 times (rotate the genetic sampling cotton swab while wiping).

Take out the genetic sampling cotton swab, put it on the envelope or white paper, and dry it in the shade for more than ten minutes until the saliva is completely dry; (the specific location for wiping is the side of the cheek or the inside of the cheek and cheek – for example, the place where the adult pinches the child’s cheek, from the wipe in the mouth)

4. Collect the second cotton swab (the other side) in the same way, and extract three (six in total) genetic sampling cotton swabs from each side;

5. For gene sampling after drying in the shade, we should put the collection cotton swabs in a marked envelope and seal it (please do not use plastic bags or plastic wrap for the sampling cotton swabs)

6. Take the sample to the laboratory as soon as possible for PCR experiments, or you can choose to mail it to the laboratory or hospital.

How to Obtain an Oral Swab Specimen

If you have been in close contact with symptoms of COVID-19 (15 minutes or more in six minutes), you should get tested.

If you have recently been to someone in an area with a positive case, you should do a swab test;

You are a person who recently travelled or travelled for business, you should take the test;

If you and your family members have recently developed suspicious persons such as fever, dry cough, fatigue, sore throat, and decreased sense of smell (taste) during the self-health monitoring process, you should go for a test;

If you have recently held or participated in large-scale, crowded dinners, parties, conferences, training and other large-scale gatherings of people, you should go to the test.

You can talk to your healthcare provider, your local urgent care, or your state or local health department about where to go to get tested (CDC, 2020A).

What is the most reliable test for COVID-19?

You may have seen the rumour circulating that oral swab tests are not as reliable as nasal swabs. But how is this measured?

Expert research has shown that nasal swabs are easier to detect nucleic acid positive, and the sampling time stays longer in the nasopharynx. Larger doses of samples can be obtained, which is the reason for the higher positive rate of nasopharyngeal swabs reported in the literature.

1. Polymerase chain reaction: fluorescence quantitative PCR, which is suitable for a large number of samples and has a low cost;

2. Second-generation gene sequencing: the NGS method, which is more accurate and can read out which generation of nucleotides and viruses the data came from.

For example, the complete data of the nucleotide sequence of the delta virus is available in the database. We compare the resulting virus to the full data, and if we do, it’s a delta virus. There will be subtle differences in the process of virus transmission, even the first and second generations are different, and subtle differences can be found through comparison. Therefore, it is possible to find out who and where the first-generation patient, patient No. 1, came from during the outbreak of this virus in this local community. It is better to use the NGS method to trace the source of the virus.

Both methods have their own advantages and disadvantages, and both can very accurately reflect whether the nucleic acid test is positive or not, and both can achieve the purpose of detection. If we need traceability. We compare the collected viral nucleotides with viral databases in all databases to aid in diagnosis and guide treatment.

Still, the information on testing for the new coronavirus continues to evolve, to the point where you may feel like you need to become a medical professional or even know where to go first. If you’re wondering whether to get tested and how it works, we’re here to help. Here’s what you need to know about COVID-19 testing and other options.

How to Swab For Covid Test

Since the outbreak of novel coronavirus pneumonia, we must have experienced nucleic acid testing. Covid swab test Nucleic acid detection plays a very important role in the process of infection diagnosis of COVID-19. It can not only find asymptomatic patients in the incubation period as much as possible but also greatly reduce the risk of infection.

Nucleic acid detection is so important. Next, Dr Li will take you to have an in-depth understanding of the relevant principles of nucleic acid detection, the difference between mixed collection and single collection of nucleic acid detection, and the matters needing attention in nucleic acid detection, to help you better protect yourself while popularizing knowledge.

To understand nucleic acid detection, we must understand the detection principle. Let’s take a look at its detection principle first.

The doctor is testing the patient's nasopharynx swab

The doctor is testing the patient’s nasopharynx swab

What is the principle of nucleic acid detection?

Nucleic acid, the genetic factor of the virus, is a macromolecular chain composed of four nucleotides. Different molecules represent different nucleotides and form a long chain. Nucleic acid detection is through the detection of nucleic acid in the chain, and this segment of nucleic acid is COVID-19 specific, other viruses do not.

Pcr test nasal swab and an antigen test difference for covid 19

Pcr test nasal swab and an antigen test difference for covid 19

The substance detected by the nucleic acid is the nucleic acid of the virus. At present, the detection technology is mainly through PCR (polymerase chain reaction) technology to detect the nucleic acid of the virus. During the detection, the nucleic acid chain of COVID-19 was used as the detection target, and the target gene sequence was amplified by PCR Test, which was combined with a fluorescent labelled probe added in the test reagent to produce a fluorescence signal.

The three forms of nucleic acid detection have their advantages.

Nasal swab test

This test method is to insert the test swab vertically into the nostril. And gently rotate the swab, stay in the nasal cavity for about 15 seconds, to test.

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Compared with throat swabs, nasal swab testing is more accurate for inexperienced testing personnel. And the risk of exposure is lower. However, it is not suitable for some patients with nasal allergies, high blood pressure and people who take anticoagulation and antiplatelet for a long time.

Throat swab test

At present, the most widely used detection method is also a form that is often used by everyone. During the sampling process, the patient opened his mouth and made an “ah” sound, and the testing personnel used a sterilized cotton swab to gently and quickly wipe the pharyngeal lateral wall and posterior pharyngeal wall of the subject many times.

COVID-19 Testing:PCR swab test,antibody test, and antigen test difference

COVID-19 Testing: Throat swab test

Throat swab testing: Often used in the testing process because it is more convenient and fast to collect, and it is more acceptable to the public, but the risk of exposure is also greater.

Anal swab test

This test method is a method of inserting a test swab into the anus and taking a sample at the fold of the anus or taking a sample at 2 to 3 cm for a new coronavirus test.

Many patients reject anal swab testing, but anal swabs can improve the accuracy of testing for new coronavirus infections to a certain extent. Some patients indeed have negative throat swabs, but positive ones are detected by anal swabs. In some patients, the anal swab test was still positive after the other two tests turned negative.

Why do multiple nucleic acid tests need to be performed?

Multiple nucleic acid tests are necessary for epidemic prevention and control.
A negative nucleic acid test does not mean that the tested person is not at risk of infection. Any detection method has the possibility of errors, especially in high-risk areas. To ensure the accuracy of the inspection results and better prevent and control the spread of the epidemic, multiple rounds of inspections must be carried out. There are also the following reasons for taking multiple rounds of detection:

After virus infection, the human body has a certain value-added period. When testing, if the virus in the body does not reach a certain concentration, we may not detect the virus.

When the specimen was collected, due to the different sampling methods, no virus cells were collected. False-negative specimens can also lead to inaccurate collection results.

Errors in the transportation process and storage of samples for inspection will also affect the results of nucleic acid testing.

Therefore, for risk areas and special populations, multiple rounds of nucleic acid testing must be carried out to more accurately and effectively detect the virus source, so as to better and more accurately prevent and control and identify infected people, and cut off the source of the virus. No matter what kind of inspection process, attention must be paid.

How to Collect a Throat Swab Specimen

Specimen collection swabs (collection swabs) are used to collect samples for medical testing. Such as swabs for collecting virus samples.

1. Prepare a clean work surface and gather supplies.
2. Perform hand hygiene.
3. If performing a throat culture on the asymptomatic person, consider wearing a surgical mask.
4. Wear clean gloves and loosen the swab collection container, if applicable.
5. Ask the person to tilt their head back slightly, open their mouth as wide as possible.
6. Depress the person’s tongue and ask them to say, “Ahh.”

COVID-19 is an infectious disease,a respiratory disease.

COVID-19 variants_Omicron

The new findings indicate that the new mutation of COVID-19, Omicron, spread earlier than everyone thought, and the scope is wider.

We must do a good job in vaccine injection and virus swab testing is the top priority.
According to the Associated Press, on Tuesday (November 30), the new findings have clearly shown that Omicron has entered many countries before the world has created its own protection system for Omicron.

The Spanish Institute of Public Health Service and Natural Environment (RIVM) detected Omicron in virus samples on November 19 and 23.

According to the World Health Organization, South Africa first reported this type of mutant virus on November 24.

At this stage, it is still not clear where this type of mutation first occurred, nor how infectious it is, but this has not prevented some countries from rushing to implement travel restrictions, especially for tourists from southern Africa.

This measure has been criticized by South Africa, and the WHO has also expressed its resistance, feeling that its actual effect is relatively limited.

The latest developments have also become increasingly clear that the travel ban cannot prevent the spread of new mutations.

The German government stated that they had seen Omicron in a man who had neither been to Africa nor had any knowledge of anyone who had contracted this type of virus.
The World Health Organization reminded on Monday that the risk of Omicron’s worldwide spread is “very high”, and initial direct evidence suggests that it is likely to be more infectious.

The COVID-19 pneumonia epidemic broke out for the first time nearly two years ago, and at this stage, the world’s response at many levels is similar to the disorder two years ago. Including random implementation of travel restrictions, and the lack of grasp of where there are risks and where there are risks.

Senior officials from all over the world try to clear everyone’s fears, saying that their vaccines are still a better way of defense. Be sure to continue to work hard to make vaccination spread all over the world. At the same time, do a virus swab test.

However, regarding the effectiveness of vaccines against Omicron mutations, although the President of the United States is also urging vaccination, the White House President’s medical consultant and the top infectious disease expert in the United States told the ABC TV program on Monday that the experts look forward to one or two in the future. Understand within a week.

What is the maintenance level of the current COVID-19 vaccine against this new mutation? Don’t know yet. But what we can do is to do a good job of virus swab testing and prevention. For example, go out less and party less.

COVID-19 symptoms;

The symptoms of COVID-19 are likely to include dysosmia, high fever, dry cough, dyspnea, chills, headache, muscle pain, sore throat, hematoma, or runny nose. At the same time, it is manifested as conscious fatigue, weakness, and weakness.
This situation may happen 2-14 days after you touch the virus that causes COVID-19.
Not all COVID-19 patients have all of these symptoms, and some people have no symptoms. That is an asymptomatic infection.
Even after recovering from COVID-19, some people are still likely to have unforgettable illnesses, such as fatigue, dry cough, or joint pain. The long-term physical and mental health hazards are unclear, but they may cause permanent damage to the cardiovascular system, lungs, or other human organs. This is more likely to occur in people with more serious illnesses, but it is more likely to occur even in people with milder illnesses.
If you have symptoms, please take a swab. If you have questions or concerns about a medical condition, please consult your health service provider.

How to obtain a nasopharyngeal swab specimen?

Overview.

Nasopharyngeal swab specimen collection of respiratory mucosal surface specimens is a method for the diagnosis of Covid-19 novel coronavirus in adults and children.

This operation can also detect patients with suspected respiratory infections caused by other viruses and bacteria.

There are no special contraindications for nasopharyngeal swab specimens. However, clinicians should treat the following conditions with caution: the recent history of nasal trauma or surgery, severe nasal septum deviation, chronic nasal obstruction, and severe coagulation.

Preparation for nasopharyngeal swab specimen sampling.

The nasopharyngeal swab is a special sampling tool, which consists of a sampling head made of soft plastic or flocked nylon. In addition to nasopharyngeal swabs, operators also need personal protective equipment (PPE) such as isolation gowns, non-sterile gloves, protective masks, and face shields.

Before starting to use, please make sure that all virus sampling tubes are labeled, and the analysis application form is filled incorrectly.

Nasal Swab Sampling Steps

We recommended that patients with suspected Covid-19 type coronavirus infection wear masks.

The patient took off the mask and blew his nose with a paper towel to remove excessive secretions from the nasal passages.

Take out the tissue. Slightly lift the patient’s head so that it can wipe into the nasal passage. Ask the patient to close his eyes to alleviate the slight discomfort caused by the operation.

Along the nasal septum, gently push the swab above the bottom of the nasal passage forward until you feel a sense of resistance indicating that the swab has reached the nasopharynx.
Insert the swab in the nostril parallel to the upper jaw.

If resistance is encountered during pushing the flocked swab, the scraper should be withdrawn, try to adjust the angle and then push again, at the same time closer to the bottom of the nasal passage.

The depth of the nose insertion should be equal to the distance from the nostril to the opening of the external auditory meatus. CDC recommends keeping the sampling head for a few seconds after it reaches the nasopharynx, allowing the sampling head to absorb the secretions, and then slowly rotating the swab to discharge it slowly (people who have done nasopharyngeal swabs will appreciate which kind of sourness Cool feeling). Your institution may also recommend sampling for a few weeks after exiting the spin. Ask the patient to wear a mask.

Nasopharyngeal swab specimen processing.

Open the sampling tube with virus transport medium, put in the flocking swab, fold out the sample tube in the groove, and discard the tail. Tighten the label sampling tube cover, and wipe the sampling tube with a sterile wipe.

Then place the sampling tube in the biohazard bag opened by the assistant. Some departments may require you to put the samples back in their original packaging and then send them for inspection. According to CDC guidelines, process the swab sample directly, or put the sample in a preservation solution or store it at room temperature.

Winter is coming, the cold current is coming, the goose feather like snow is flying all over the sky, and the whole world is wearing a white coat.

Many customers once again throw this “soul question” to us. “Can your Viral Transport Kits adapt to the cold environment?”

He answer is yes. Let’s follow Cell medical Dr. Li for experimental verification!

Experimental purpose

Verify that the Viral Transport Medium of cell medical (Dongguan) Co., Ltd. has no significant impact on its service performance after low-temperature freezing and thawing.

Experimental scheme

Simulate the process of low-temperature freezing during transportation, place the sampling tube in a low-temperature environment for 24 hours, and then melt at room temperature. The sampling tube products stored normally without freezing and thawing were used as the control. Each group was added with virus mixture, stored at 4 ℃ for 24 hours, and then bathed in water at 56 ℃ for 30 minutes for nucleic acid extraction and nucleic acid detection. Set 2 repetitions for each group.

1. Low temperature icing simulation: set two low temperature gradients and place the sampling tube in two low temperature environments of – 20 ℃ and – 80 ℃ respectively.

2. Mixing of virus solution: We used two different concentrations of virus solutions, representing high and low concentration gradients respectively. The copy numbers of virus solution were 106 copies / ml and 104 copies / ml, respectively. Simulate the actual sampling process, add the virus solution in the volume ratio of 1:10 to the sampling solution, and the virus solution is 100 μ 50. 1ml of sampling solution and add 100 ml to it μ L of oral liquid.

3. After mixing each group, place it in 4 ℃ environment for 24 hours and inactivate it in 56 ℃ water bath for 30 minutes.

4. Extract the nucleic acid of each group of virus, and detect the virus content of each group by RT qPCR. The CT value is used as the basis for result evaluation. The higher the CT value, the higher the detected concentration.

5. The experimental groups are as follows:

Main experimental materials

  •   Sampling solution: virus preservation solution produced by cell medical (Dongguan) Co., Ltd.
  •  virus diluent: the virus isolation serum-free medium of Cell medical was used for gradient dilution.
  •   virus for verification: porcine epidemic diarrhea virus. Its structure and genome size are similar to those of New Coronavirus.
  •   nucleic acid extraction reagent: non cleavage nucleic acid extraction reagent (magnetic bead method).

All about the Nasal Swab

Nasal Swab:nasopharyngeal np swab.

The specimens collected from nucleic acid samples are mainly pharyngeal swabs, which are divided into “nasopharyngeal swabs” and “oropharyngeal swabs“.

Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth, and nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

How to do a nasopharyngeal swab?

A man was doing a nasopharyngeal swab sample

A man was doing a nasopharyngeal swab sample

Nasopharyngeal swab sampling method.

Hold a swab close to the nostril to enter, and slowly go deep along the bottom of the lower nasal tract.

Since the nasal tract is curved, do not use too much force to avoid trauma and bleeding.

When the top of the swab reaches the posterior wall of the nasopharyngeal cavity, rotate it gently for one week (stay for a moment in case of reflex cough), then slowly take out the swab and immerse the swab head into a tube containing 2 ~ 3ml virus preservation solution.

About Nasal swab sample collection.

How to take a swab sample?

Ask the patient to take off the mask and blow his nose with a paper towel to remove excess secretions from the nasal cavity. Remove the swab from the package.

Tilt the patient’s head back slightly to make the nasal passage easier to pass through. Ask the patient to close their eyes to reduce the mild discomfort of the operation.

Gently insert the swab over the bottom of the nasal canal along the nasal septum until the nasopharynx stops when resistance is felt.

Insert the cotton swab parallel to the upper jaw into the nostril.

If you feel resistance when passing, step back and try to reinsert it at another angle to bring it closer to the bottom of the nasal canal.

The depth of the swab should be equal to the distance from the nostril to the opening outside the ear.

CDC recommends placing the swab for a few seconds to absorb enough secretions, and then slowly removing it while rotating the swab.

Some organizations may also recommend rotating the cotton swab several times before taking it out.

After removal, ask the patient to put on the mask again.

Specimen processing

Open the virus transport medium and insert the swab into the collection tube.

Break the swab at the groove and discard the remaining part. Seal the labeled collection tube and place it in the biohazard garbage bag.

According to convention, you can return the sample to its original packaging for disposal.

Follow CDC instructions for direct treatment of swab specimens or place swabs in medium with or without refrigeration.

Quick covid test

Quick covid test |How does covid testing work?

Posted on by

A new covid test at home has been authorized by the U.S. Food and Drug Administration (FDA) for emergency use (EUA).

Here’s what you need to know about testing at home.

How can I get quick covid test?

Cell medical’s covid test at home now has a prescription, which means Americans can get one from their health care provider.

If doctors suspect that their patient is infected with covid – 19 within the first six days of symptom onset, they can prescribe a rapid test.

Quick covid test Rapid Antigen Test Kit Nasal Saliva Test at home

How much does it cost?

Please contact us for more details.

How does testing work?

Rapid Antigen Test is a lateral flow test, a portable covid test that usually returns results faster than the widely used laboratory based PCR test.

It works by detecting nasal swab samples and provides positive or negative results within 10 minutes. The results appear on test strips exposed to nasal swab samples.

The FDA said flocked swab can be collected from people aged 8 and over, but if the tested children are less than 14 years old, it should be collected by adults.

How accurate is the test?

Cell medical claimed that the time when the positive results of the test matched the PCR test was 84.8%, and the negative results matched the PCR test were 99.1%.

FDA said that the negative test results of covid test do not necessarily exclude the possibility of covid – 19 infection.

“and should not be used as the only basis for treatment or patient management decisions, including infection control decisions.

“People who are negative and continue to experience COVID 19, have a fever, cough and / or shortness of breath, may still have SARS – CoV – 2 infection. Follow up care should be sought from doctors or medical staff. ”

Not all side flow tests require the use of prescriptions. On December 15, the FDA issued the EUA for the first outside counter flow covid test at home.

The covid – 19 family test also uses nasal swab samples to detect covid infection and works with people aged 2 years and older.

The FDA said that in the population with covid symptoms, the ellume test correctly identified 96% of positive samples and 100% of negative samples. In the population without symptoms, it collected 91% of positive samples and 96% of negative samples.

Similarly, the FDA said that the negative results of the test do not necessarily exclude the possibility of covid infection.

Broader prospects

According to CDC data, as of Monday, the United States had reported 47.5million cases of covid and 778,316 deaths.

The data also showed that 432 million people were vaccinated on Monday.

A stock photo shows a schoolgirl receiving a nasal swab sample.
