Nasopharyngeal swab sampling： A thin flocked swab into the nostril, from the lower nasal meatus to the posterior wall of the nasopharynx.

And then twisting the swab for sampling.

The depth of the sampling swab into the nasal cavity is approximately the distance from the tip of the nose to the earlobe.

How to collect a Nasopharyngeal (NP) swab

1. Keep your head still, to remove the secretion on the surface of the anterior nostril;

2. Measure the distance from the tip of the nose to the earlobe with a swab as well as mark it with your finger. Put the swab right into the nasal dental caries in the direction perpendicular to the nose (face), and also reach the posterior nasopharynx when it comes across resistance, to make sure that the swab stays in the nose for 10-15 s, gently rotate 3 to 5 times to secure the examination piece.

There is definitely no demand for the sampler to stand straight opposite the patient. The advantage of standing on the side is that if the patient has coughing, sneeze, etc, it can be avoided in time.

It is vertical to the coronal airplane of the head or the face and also permeates deeply from the inferior meatus to the posterior wall of the nasopharynx, as well as it is enough to feel the wall surface. The depth of the nasopharyngeal swab right into the nasal tooth cavity is about the range from the pointer of the nose to the earlobe (see picture).

Nasopharyngeal sampling

Nasopharyngeal sampling

3. The nasopharyngeal swab must be turned on the nasopharyngeal mucosa, maintained for 10-15 secs, and after that got rid of. The kid’s participation is poor. In practice, we typically obtain the swab in three to five secs after completely twisting it 2-3 times.

Nasopharyngeal swab vs nasal swab

A nasal swab (often called an anterior nose test): A sample taken by touching both sides of the nasal wall. The nasopharyngeal swab is to probe from the nose to the throat.

What is the nasal swab technique?

The nasal swab approach uses a swab to accumulate an analysis example from the nasal membrane. The nasal swab examination (frequently described as the former nasal test) involves putting the swab around 0.5-0.75 inches deep into the nostril as well as turning it in one nostril for 10-15 seconds while touching both sides of the nasal wall, then making use of the same cotton swab, Gather in the other nostril similarly. Since this approach is less invasive, it is usually extra comfortable for the patient – and is additionally the approach utilized when self-testing.

Nasopharyngeal swab

Impacted by elements such as age and also face structure development, there are private differences in the collection deepness of nasopharyngeal swabs.

We should pay attention to personal protection when collecting nasopharyngeal swabs, and clean the nasal cavity before collection.

If the patient has nasal septum curvature, the background of nasal surgery, rare coagulation characteristics, etc., the patient should inform the collection staff in advance to avoid damage to nasal caries.

During collection, the patient should tilt his head back to ensure smooth entry of the nasopharyngeal swab.

It might be accompanied by discomfort and discomfort in the nasal tooth cavity.

Furthermore, nasal bleeding might happen after nasopharyngeal swab collection.

A percentage of blood loss does not call for unique therapy. If the amount of blood loss is huge or lasts for a long time, you must go to the hospital for hemostasis therapy in time.

Additionally, clients with signs and symptoms such as edema as well as blood loss in the nasopharynx should stay clear of nasopharyngeal swab collection to avoid worsening the problem. Before the nasopharyngeal swab collection, you must avoid taking antibacterial and also antiviral drugs to stay clear of impacting the examination results.

Nasopharyngeal Swab Pcr Test

There are two broad categories of COVID-19 tests: viral diagnostic tests (which detect an active COVID-19 infection) and antibody tests (which detect past COVID-19 infections).

The PCR swab test is a qualitative oropharyngeal or nasopharyngeal collection used to detect the novel coronavirus, the virus that causes COVID-19. This test helps determine if you have been exposed to the virus. The COVID-19 PCR test is a molecular test that detects the genetic material of the virus.

The current more accurate test for COVID-19 is to use RT-PCR to assess the presence of SAR-CoV-2 RNA in collected samples. If anything, the subject was almost certainly infected with the virus.

What are the diagnostic tests for the COVID-19 virus?

With the development of testing for COVID-19, there are now four main forms of diagnostic testing for the virus:

Nasal Swab Test: A test involving a shallow nasal flocked swab.

Cell medical flcoekd swab

Cell medical flcoekd swab

Nasopharyngeal test: A test that involves a deeper nasal swab using PCR technology.

Saliva Test: A test involving a saliva sample and PCR technology.

Oral swab test: An innovation in COVID-19 testing that allows anyone to test quickly, non-invasively and easily. Use PCR technology.

The COVID nasal swab test, also known as the nasal swab test, is a medical test used to detect viruses in the nose that can cause respiratory infections.

 

How does Nasopharyngeal Swab detect coronavirus?

Nasopharyngeal testing collects a sample from the back wall of the nasopharynx.

(1) Measure the distance from the nostril to the base of the ear with a swab and mark it with your finger.

(2) Let the patient’s head relax naturally, put the swab against the nostril wall and slowly rotate it into the patient’s first nostril to the nose and palate, and then slowly take it out while wiping. With the same swab, leave the swab in the nose for 15-30 seconds, then gently swirl 3 times. Wipe the other nostril in the same way;

(3) Put the flocked swab into the virus delivery medium, break the swab rod, and place it completely in the tube.

(4) Tighten the cap of the tube, make a mark, put it in a plastic bag and seal it

(5) If it is necessary to collect from both nostrils, a swab should be used separately.

(6) Store at 4°C (short-term storage).

What types of nasal swab sampling are available?

There are three types of sampling swabs used in the nasal cavity, namely nasopharyngeal swabs, nasal cavity swabs, and middle turbinate swabs.

nose structure

nose structure

Nasopharyngeal testing collects a sample from the back wall of the nasopharynx.

Sampling from the middle turbinate location is not as uncomfortable as the nasopharynx.

Anterior nasal swab/nasal swab:

Taking a sample in the anterior position of the nose does not cause discomfort and can be used by people with narrow nasal passages.
The sampling difficulty is low, and the patient can easily complete the anterior nose sampling by himself.

Although nasopharyngeal swabs, nasal swabs and turbinate swabs have different sampling methods, they can all be used to collect samples and then use PCR results to determine whether the owner of the sample has been infected with the new coronary pneumonia virus.

Do you feel any discomfort? Does it hurt!

Nasopharyngeal Swab Sample

Nasopharyngeal Swab Sample

Nasal swabs and throat swabs are the two most widely used sampling methods. Just use a flocked swab to gently wipe the throat mucosa or nasal mucosa, and it can be completed in 1 to 2 seconds, which is generally not uncomfortable. However, for some more sensitive people, irritating retching, nausea or choking may occur. At this time, it is best to use a tissue to cover the mouth and nose and try to hold it back to avoid vomit or sputum. create pollution.

How does nucleic acid testing relieve the discomfort of sampling?

Both nasopharyngeal swab sampling and oropharyngeal swab sampling will make the sampled person feel slightly uncomfortable, which can be relieved after a short rest. Therefore, during the sampling process, the sampled person should cooperate with the sampling personnel as much as possible, relax as much as possible, and do not move the head excessively to avoid scratching the mucous membrane with the sampling swab.

Is the nasal swab COVID test the best test?

What are the current testing methods for COVID-19?

There are two types of virus detection:

  • Nucleic acid amplification test (NAAT) (PCR test) and antigen test.
  • Antibody tests (also called serology tests) can show whether you have been infected in the past.

Mouth Swab vs Nasal Swab

HOW TO USE

HOW TO USE

Nasal swabs generally enter from the nasal cavity and take the secretions at the back of the nasopharynx, while pharyngeal swabs enter from the mouth to the throat and take local secretions for inspection, that is, the two enter in different ways.

The nasopharyngeal swab test does not produce painful symptoms, and some patients experience discomfort. This inspection is to use a medical flocked swab to enter the nasopharynx to take a small number of secretions and send them for inspection. The pathogenic bacteria can be isolated through bacterial culture. During the operation, the patient will experience mild nausea and discomfort, which is generally within the tolerable range. During the operation, the medical staff is gentle and skilled, so there will be no pain.

Activates unconscious, instinctive reflexes. Depending on the intensity of the body’s response, discomfort, tearing, pain, and other reactions can result. Some people gag, cough, sneeze – it’s all part of the same reflex. For people who are more prone to headaches, this can cause intense discomfort.

Swab testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

A nasal swab refers to a swab deep from the nasal cavity, all the way to the nasopharynx, and the secretion is taken for smearing.

Throat swabs are taken directly from the posterior pharyngeal wall of the oral cavity and the tonsillar fossa by opening the mouth. Nasal swabs are generally slightly more painful than throat swabs because they need to be passed through the nasal cavity. If there are structural abnormalities in the nasal cavity, such as a deviated nasal septum or hypertrophy of the turbinate, or there is hyperplasia in the nasal cavity, such as nasal polyps or the operator does not know much about the anatomical structure of the nose, it is possible that a cotton swab may not easily reach the nasopharynx through the nasal cavity. Partial or damaged nasal mucosa, causing local bleeding or pain and other discomforts.

Nasal swab and throat swab which is painful?

Which is more accurate between nasal swab and throat swab? Essentially, if the operation is standardized, there is basically no difference between the two sampling methods, but we usually eat and drink water, etc., which will reduce the virus accumulation in the oropharynx to a certain extent. , In practice, the positive detection rate of nasal swabs is slightly higher than that of throat swabs. In general, oropharyngeal swabs are suitable for most people and are convenient and fast, while nasopharyngeal swabs are slightly more accurate, but the human body does not feel comfortable.

Precautions before nasal swab testing?

1. Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting;

2. During the inspection, reduce swallowing and do not do throat clearing (such as expectoration and spitting).

3. Pay attention to maintaining a distance of more than 1 meter between people and minimize conversations;

4. Do not drink beverages (including water), smoke, drink, chew gum, etc. 30 minutes before sampling;

5. The tested person should be informed Whether the collection personnel have a relevant past medical history (such as the history of nasal surgery, deviated nasal septum, blood disease, throat disease, etc.);

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab. I see a lot of netizens saying that the nasal swab is very painful and sour, this is because your posture is not correct! !!

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab, their purpose is to let the cotton swab sample from the inner wall of the throat. Nasal swabs are not meant to poke your heavenly lid!

Therefore, you should tilt your head as far back as possible to allow the flocked swab to go in horizontally. That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds. But if you keep your head upright, the cotton swab can only be stabbed from the bottom to the top, which will definitely stab the upper part of the nasal cavity. That position is very sensitive, and it hurts when stabbed. And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

Flu Swab Test

Flu Swab Test

Posted on by
Influenza, commonly known as influenza, is an acute respiratory disease caused by influenza A, B, and C viruses, and belongs to Class C infectious diseases. Influenza is an illness that spreads relatively easily from person to person and can infect large numbers of people. While most people recover quickly from the flu, some, such as older adults, are at risk of serious illness and even death.

Flu Swab Test

Influenza viruses come in many different forms. A flu swab is a method of taking a sample from a person. Medical staff check patients for flu. If so, what kind of flu virus can be spread by inhalation through the nose and throat of an infected person.
When the flu virus infects a person, it spreads through the respiratory tract. The nose and throat are where the virus lives and grows, causing symptoms such as a runny nose, sore throat and cough. These places are also the easiest places for doctors to obtain samples. As a result, doctors can often use flu swabs to determine whether a patient has the flu, which often spreads quickly in a population.
Due to public health, some government medical agencies may wish to track the spread of the disease. Since influenza viruses also mutate rapidly, new influenza viruses are produced regularly. The type of flu a person has can also be important information for the public health system.
Finally, a doctor may need to determine whether a person has the flu so an appropriate treatment plan can be instituted. There are several ways a doctor can use a swab to determine if a patient has the flu virus. An area of ​​medical professionals, usually to test for microbes. (Nasal swab for flu)

How to do Nasal Swabbing for COVID

How to Swab for the Flu?

They usually have a long swab stick with a soft swab tip at the end, made of cotton material, polyester, polyester or rayon tip, nylon flocked swabs. is sterile, so the test only analyzes the microbes in the sampled area. During the flu swab procedure, doctors usually insert the end of the swab into the patient’s nose and spin the flu swab to collect as much mucus as possible.
A doctor can take a sample by inserting a swab into the top of the throat through the nose. If the virus grows heavily in the area, the flu can cause dizziness.
Doctors have several different ways to test a cotton swab for the flu virus. The test that takes a few days to a week to complete is a viral culture, in which viral particles are grown in human cells.
Rapid tests include tests that analyze the sample for the presence of genetic material or antigens from the flu virus. An antigen is a special molecule in a virus. Some commercial tests contain antibodies, and the presence of antigens can be recognized by their linkage to the antigens.
These tests are less than an hour, but may not be as accurate as viral cultures. A runny nose and sore throat can be symptoms of the flu.

How do I know if I have the flu?

If you have a fever, cough, sore throat, runny or stuffy nose, body aches, headache, cold and/or fatigue, your respiratory illness may be the flu (flu). Some people may experience vomiting and diarrhea, although this is more common in children. People can get the flu without having a fever. Influenza viruses usually cause the most illness during the colder months of the year. However, the flu can also occur outside of a typical flu season. In addition, other viruses can cause flu-like respiratory illnesses. Therefore, it is not possible to tell if you have the flu based on symptoms alone. If your doctor needs to determine if you have the flu, you can do laboratory tests.

Can I get the flu and COVID-19 at the same time?

Yes. Co-infection with influenza and other respiratory illnesses, including COVID-19, is possible. Health experts are still studying how common the condition is.

The flu is similar to some of the symptoms of COVID-19, so it’s hard to tell them apart based on symptoms alone. The swab diagnostic test helps determine if you have the flu, COVID-19 or other respiratory infections.

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.
