Influenza requires a throat swab test. Tests can be used to determine whether a patient is infected with the flu virus, and then targeted treatment can be given.

Influenza patients will have symptoms of dry cough, and they will also have dry cough symptoms after being infected with the new coronavirus, so throat swab tests should be performed for patients who have been in contact with people infected with the new coronavirus or who have been to the epidemic area. Patients infected with the new coronavirus generally do not need a throat swab test to determine whether they are infected with the new coronavirus.

Covid Test Throat Swab

Covid Test Flu Throat Swab

The throat swab detection process is as follows: the tested person needs to sit facing the sampler, raise his chin, and open his mouth wide. in special equipment.

These tests include reverse transcription-polymerase chain reaction (RT-PCR), viral culture, and immunofluorescence assays. All we require is that a health care provider swipe the inside of your nose or the back of your throat with a swab and then send the swab for testing. Results may take one to several hours.

Accuracy of throat swabs for influenza.

A throat flocked swab for influenza is more accurate, but there are no authoritative experimental statistics for its specific accuracy.

Throat swab testing for influenza is very fast, economical, and simple, but if the throat swab is negative.

It does not mean that there is no Influenza that may be caused by contamination of specimens, improper sampling of specimens, etc.

And comprehensive judgment should be made in combination with clinical symptoms, epidemiological history, and antigen testing.

When taking a throat swab for influenza, insert the swab completely into the throat from the oral cavity, and moderately wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall with the throat wall and the reddened part of the palatine tonsil as the centre. But avoid touching the tongue. Then remove the test strip. Insert the sampled swab into the solution in the sample extraction tube

So that the specimen is dissolved in the solution as much as possible, and the results can be observed within 15 to 20 minutes.

After more than 30 minutes, the displayed results are usually not clinically meaningful.

If there are two red lines or three red lines in the patient, it means that the throat swab test for influenza is positive.

And there are two red lines, which usually means that there is influenza A or B. If it is three red lines, it means that it is a mixed infection of influenza A and B.

If only one red line appears, the throat swab is negative.

If the reaction line does not appear, the test is invalid, and it is recommended to use a new test card to test again.

Is it a cold or the flu? How to distinguish?

1. Influenza: fast and furious,

If you feel like you’ve been hit by a truck, you might have the flu. Symptoms such as sore throat, fever, headache, muscle aches, congestion and cough can come on suddenly. Colds are usually less intense and include a runny or stuffy nose. The flu gets better in 2 to 5 days, but you may feel the discomfort for a week or more. Colds come on slowly and last up to 10 days.

2. Fever: Usually means the flu

While some people have a mild fever when they catch a cold, most do not. If you have the flu, your body temperature may reach 38-40°C. The flu tends to be higher in children, and children may also be more likely to develop a fever.

3. Flu: Fatigue can last for weeks

You may start to feel very tired and sore. Fatigue and weakness can last up to 3 weeks, and even longer in older people and people with long-term (chronic) illnesses or weakened immune systems. Colds are self-limiting and you usually get better within a few days, usually 1 week to 10 days.

4. Cold and flu: Both can cause headaches

Like other symptoms caused by a cold, headaches that accompany a cold are still milder than those caused by the flu.

5. Cough: Both colds and flu can cause

Colds and flu are respiratory illnesses that both affect your airways, so both can cause a cough.

Pneumonia is a lung infection that can be a complication of the flu. If you have a persistent cough, fever higher than 38°C, chills, difficulty breathing, shortness of breath or chest pain, please seek medical attention in time.

6. Earache: Maybe from a cold or the flu

Congestion from either disease can raise the pressure in your ears. This affects the Eustachian tube, where the larynx and middle ear communicate. It may cause dull ear pain, hearing loss, and a “popping” feeling in the ears. These symptoms will disappear as the disease improves.

If other symptoms get better and the earache persists or you experience sudden, intense pain, see your doctor. You may have an ear infection that needs treatment.

7. Colds: Usually starts with a sore throat

These early symptoms tend to last 1 to 2 days, and a runny nose and nasal congestion are also common. A sore throat also accompanies the flu, but if it’s the flu, you may feel tired and have other symptoms right away.

8. Stuffy nose: Could mean a cold

Simple nasal congestion without fever and general tiredness tends to lead to a cold, although many flu sufferers also say they have nasal congestion and sneezing.

Both colds and flu can cause sinus infections. In addition to a thick yellow or green snot, a sinus infection can also cause headaches and pain in the forehead, cheeks, and bridge of the nose. Sudden head movements or strains can make the pain worse.

9. Flu throat swabs can quickly identify the flu

ABOUT US

The quickest way to find out about your illness is to go to the hospital for a checkup.

A nasal or throat swab can usually tell you if you have the flu virus in 30 minutes or less. If a test shows you have the flu and your symptoms started within the past 48 hours, your doctor may recommend antiviral medication to help you recover faster.

10. Influenza: start antiviral drugs as soon as possible

These medications can give you relief and shorten your condition within 1 to 2 days, especially if you start taking them within 2 days of getting sick. Over-the-counter medications can also relieve symptoms such as coughing and congestion. Read labels and directions carefully so you know what the medicines do and how to use them.

11. Colds: Over-the-counter medications can ease symptoms

12. Hand washing is key

Washing your hands is very important to protect yourself and not spread the flu to others. Wash your hands with soap and warm water, preferably the six-step method. Alcohol-based hand sanitizers are also effective.

Wash your face frequently during cold and flu season, especially after coughing, sneezing, or having a runny nose. What if I can’t find a tissue? Face your elbow when sneezing or coughing instead of covering your mouth with your hand.

13. Get vaccinated

There is now a flu vaccine that protects against the flu, and it’s made from a protein from the previous year’s flu cases. It helps your body prepare to recognize and fight when you’re exposed to the virus again. Note: The flu shot won’t give you the flu!

The flu shot is very important for children over 6 months of age, pregnant women, adults 50 years and older, and people with long-term (chronic) illnesses or weakened immune systems.

 

COVID-19 Swab Test: What you should know

COVID-19 Swab Test: What You Should Know

Posted on by

An abrupt COVID-19 has brought flocking swabs, nasopharyngeal swabs, oropharyngeal swabs, nucleic acids, antigens, PCR and also other extremely professional terms right into the public eye. Today, CellMedical will certainly offer you preferred scientific research: those aspects of Coronavirus (COVID-19) screening.

What is a flocking swab, nasopharyngeal swab, or oropharyngeal swab?

When nations are executing a new round of nucleic acid screening, a report is spreading out in circles. The basic concept is “the cotton bud used for sampling have reagents on them, which are hazardous”. Some netizens also left a message to the CellMedical firm backstage, saying that after seeing the pertinent reports, the elderly at home shared that they did not want to take part in nucleic acid testing, and also really hoped that the younger generation would additionally attempt not to undertake nucleic acid testing as well as antigen testing.

“The covid test swab is not the same as the cotton swabs used in daily life, but it does not contain reagents, nor is it toxic”. ( Click here to learn more )

What is a flocked swab and why choose flocked oropharyngeal and nasopharyngeal swabs?

A flocked swab is used because it is more suitable for sampling and testing. The flocking swab(learn more) is made of nylon fiber flocking technology, and the front end is coated with nylon short fibers fixed in a vertical manner, so that there is no absorption hole in the entire collection area of ​​the collection swab. In this way, the collected sample is not dispersed and retained in the fiber, which facilitates faster and more efficient elution. Relevant data show that CellMedical flocked swabs can elute more than 95% of the sample collection volume; traditional cotton swabs, especially those made of absorbent cotton, cannot completely collect and elute samples.

Enlarged view of flocked swab

Enlarged view of flocked swab

Nasopharyngeal swabs – which require a swab inserted into the nose to collect samples from the back of the nose and throat – are the gold standard for collecting samples for diagnosis. But the process is technically difficult, often uncomfortable for patients, and requires personal protective equipment that may be in short supply.

Oropharyngeal swab – the oropharyngeal swab is a method of collecting oropharyngeal specimens by entering the sampling swab through the mouth – compared with a nasopharyngeal swab, it is less difficult, more acceptable to the public, and more universal. 

What exactly is PCR nucleic acid detection?

PCR (Polymerase Domino Effect, polymerase chain reaction) innovation is a wonderful creation, without the creation of PCR modern technology, there would be no modern-day molecular biology. Nucleic acid detection modern technology has likewise entirely transformed several techniques such as genetics, medication, and also forensics, allowing human beings to accomplish significant steps such as hereditary testing, viral infection identification, and also genetic testing.

"<yoastmark

Basically, PCR nucleic acid detection: To significantly magnify nucleic acid till it can be identified by equipment detection.  Yet if you increase the size of the nucleic acid, 1 ends up being 2, 2 comes to be 4, and also 4 ends up being 8. Consequently, PCR innovation is a method of amplifying nucleic acid.

After the covid-19 contaminates the human body, it will initially increase in the respiratory system. So it can be determined whether the body is infected by finding the viral nucleic acid in sputum and nasopharyngeal swabs. After a duration of infection, typically 7-10 days later, the body will certainly create specific antibodies versus the virus. IgM antibodies show up initially, adhered to by IgG antibodies. So immunological discovery approaches can identify these specific antibodies to identify whether the human body is carrying the virus.

Will the results from different nucleic acid testing institutions be consistent?

PCR nucleic acid detection has a strict standard procedure. It is the same SOP (Standard Operation Procedure). At the exact same time, all nucleic acid labs, regardless of dimension, must adhere to the same technological demands, and also the design and building of laboratories additionally have uniform specifications. Also, research laboratory screening staff have to go through standard technical training and also acquire a nationally identified task certification before they can work. It resembles KFC’s fried chicken all use the exact same dish. Whether it’s a fast window in the station, a sizable and comfortable dine-in in the town hall, or home delivery, you can constantly eat deep-fried chicken with the exact same preference, do not fret will certainly strike rumbling.

Therefore, no matter which institution we conduct nucleic acid testing, the outcomes need to coincide.

The collection of samplings from different components has different clinical importance. Along with the popular nasal swabs and throat swabs, sputum, blood as well as rectal swabs；

Nasal and throat swabs – upper respiratory tract specimens

Sputum – Lower Respiratory Tract Specimens ( Saliva Collection Kits )

Anal swab – digestive tract specimen

Blood – Antibody Test Specimen

What is the difference between nucleic acid testing and antibody testing?

The distinction between both is a positive nucleic acid shows the presence of viral nucleic acid in the sampling. Which suggests that the infected individual might be infectious. A favourable IgM antibody shows that the patient remains at the beginning of infection. IgG antibodies indicated that the patient had SARS-CoV-2. However, we were unable to determine whether it was transmissible. Compared with antibody detection, PCR nucleic acid discovery is much more sensitive and is additionally the “gold criterion” for laboratory detection.

Therefore, in recent cases, doctors discussed that the patient has symptoms of infection.

What factors may affect COVID-19 nucleic acid test results?

1. Viral load: In summary, when the viral lots are low. False negatives may occur.

2. The coronavirus may alter, which may further impact the accuracy of the test in the future.

3. Testing method: In the recently reported genuine tasting scene, several participants reported that the swab only revolved left and right in the mouth, and it really felt like it was only touching saliva.

However, did not reach the lingual and palatal arc, and the respondents did not have nausea and also reflexes. Sex-related security action, this type of tasting has a high possibility of not gathering exfoliated cells of the respiratory tract, so it is vulnerable to missed discovery, leading to false unfavourable results.

What is viral transport medium ?

What is viral transport medium ?

Posted on by

Viral transport medium is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling and is usually called virus preservation solution in China.

Usually, in nucleic acid testing (PCR swab test), we cannot perform nucleic acid PCR directly at the sample collection site.

We need to add virus preservation solution (VTM) to the samples collected by swab for transfer check.

What is a virus?

Viruses are microorganisms whose structure is very simple.

There is no way to complete the process of self-replication.

They need the help of host cells and the nutrition of the host to complete virus replication.

The virus can infect humans as well as many other animals.

Influenza viruses such as common infectious diseases are usually RNA viruses.

There are many common viruses that cause human infection, which can cause respiratory diseases, such as cold virus, influenza virus, HIV and influenza A virus.

Since it has no cellular structure of its own, the virus itself cannot replicate.

But invades the gene into the host cell and replicates the new virus with the help of the latter’s replication system.

In conclusion, viruses are diverse and can cause damage to multiple parts of the body. “

After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the sampling swab ( flocking swab ) will be put into the preservation solution ( viral transport media ) for preservation and transportation.

What is the viral transport medium used for?

pcr test

PCR test

The inactivated viral transport medium can perform protein denaturation on fresh clinical virus specimens to inactivate the virus. Prevent secondary infection and ensure the safety of transportation and testing personnel. The inactivated samples can be used with a variety of virus extraction kits.

The nucleic acid extraction instrument can quickly extract nucleic acids.

At the same time, with the respiratory pathogen PCR detection kit (VTM Kits) to achieve rapid detection. The specificity and sensitivity are not affected.

Virus preservation solution has many functions:

1. The operation is simple, and the liquid contains ingredients that can denature proteins, thereby inactivating the virus;

2. Contains inhibitors to protect the stability of viral nucleic acid to a greater extent and greatly improve the nucleic acid extraction rate;

3. Stored at room temperature for 12 months before sampling.

The airtightness is good, which is convenient for storage and transportation and saves transportation costs.

Cell medical (Dongguan) Co., Ltd.

Viral transport media include inactivated and non-inactivated viral transport media.

Contains Hank‘s Liquid, Potassium Chloride, Magnesium Chloride, Calcium Chloride, BSA, etc. The combination of various antibiotics has antibacterial and antifungal effects.  Bovine serum albumin (BSA), as a protein stabilizer, can form a protective film on the protein shell of the virus. Making it difficult to decompose and ensuring the integrity of the virus; Hank’s buffer The neutral environment constructed by the agent helps to increase the survival time and infection stability of the virus.

2. To transport nasopharyngeal flocked swab specimens or tissue specimens from specific parts from the sampling site to the testing laboratory for PCR extraction and detection.
3. Preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture.
Flocked Sterile Swabs

Disposable sampling swabs, We believe you are familiar with them in the past two years because most of the testing tools used for nucleic acid testing (PCR tests) are disposable sampling swabs.

Usually, we see most nasal swabs and throat swabs, and the sampling swabs we commonly use are flocking swabs.

The flocking swab is a disposable sampling swab composed of a nylon short fibre fluff head and abs plastic rod.

Recently, there have been many concerns about rapid antigen detection on the Internet.

One of them is that if the “single-use sample collection swab” (sampling flocked swab) used in the antigen test is “non-sterile” and “non-sterile”. Bacteria” products. There are risks when using it.

Citizens disinfect the sampling swab with alcohol before conducting antigen testing at home?  ( Alcohol disinfection is not advisable)

Experts and industry insiders say such concerns are unnecessary as long as qualified products are available through formal channels.

Discard damaged or contaminated swabs.

Specimen collection sterile flocked swab

Specimen collection sterile flocked swab

Are there risks to using “non-sterile” “non-sterile” Specimen collection swabs?

There are two main issues that netizens worry about:

One is to worry about the “bacteria” of the sampling swab, which will affect the results of the antigen test, such as “false positives”;

The second is to worry about the “bacteria” of the sampling swab. During the sampling process, “bacteria” will enter the human body with the sampling swab and affect health.

Nasopharyngeal swab test

Nasopharyngeal swab test

Regarding the effect of “bacteria” sampling swabs on antigen test results, experts said that this is a misunderstanding caused by confusing bacteria and viruses.

You know, the antigen test “looks” for the antibodies produced by people infected with the new coronavirus.

The display window of the reagent strip contains a protein that recognizes the antibody, like a dam, blocking the colloidal gold that binds the antibody to the virus. So it appears red in the display window.

Therefore, even if the sampling swab contains “bacteria”, the kit will “ignore” it and focus on “finding” the antibodies produced by the new coronavirus infected person.

Since the kit is not interfered with by “bacteria”, it will not affect the results of antigen detection.

For some people who think that “bacteria” sampling swabs will affect human health, experts say that this may be due to a lack of understanding of “sterile” products.

Sterile

The single-use Specimen collection swab can currently be applied for registration as a second-class medical device, and can also be registered as a first-class medical device (the third-class is the highest level) in the regulatory department.

If it is a Class II medical device, it must meet the sterility requirements when it leaves the factory. While a Class I medical device has no relevant requirements and can be listed in the state of “non-sterile” and “unsterilized”.

Experts said that “sterility” refers to the state of no viable microorganisms. All medical devices must meet certain hygienic requirements, such as strict control of the number of microorganisms before they can be qualified for the market.

Flocked Sterile Swabs

Flocked swabs are mainly used for oral and nasopharyngeal sampling, cervicovaginal sampling, and laboratory testing.

Sterile Flocked Nasopharyngeal Swab is a 100% nylon flocked swab that provides exceptional absorption quality with a flexible handle engineered to reach remote areas of the nasopharynx for specimen collection.

According to different uses, it can also include nasopharyngeal swabs, throat swabs, oral swabs, DNA swabs, and cervical swabs.

It is similar to the above classification, but it is slightly different.

For laboratory testing centres and hospitals.

What are the advantages of flocked Sterile swabs?

Using nylon fibre flocking technology. The front end of the swab has nylon staple fibres fixed vertically. By making the entire collection area of ​​the swab free of absorbent holes. The sample does not scatter and become trapped in the fibres, facilitating faster and more efficient elution.

This makes flocked swabs ideal for PCR work, as flocked swabs are biocompatible and ideal for PCR work.

Combination features of our single-use virus sampling tube kits (vtm swab kits):

Disposable virus sampling tubes include sampling swabs and sampling tubes (vtm kits).

Flocked Nasopharyngeal Meaning Swab Test Sample Collection Vtm Kit

Test Sample Collection Vtm Kit

1. Sampling flocking swab: our company uses a nylon flocking swab (vtm swab). Because nylon flocking has no toxic effect on microorganisms and viruses and does not contain RNase and DNase.

It can maximize the collection and release of virus samples and ensure the accuracy of PCR test results.

The flocked swab rod: ABS material, with a unique breakpoint design.

Convenient to put into the sampling tube without contamination.

2. Virus sampling tube: The tube body and tube cover are made of polypropylene, which will not deform at high temperature and high pressure (121°C, 15min).  And will not become brittle at low temperatures (-196°C).

Resistant to static extrusion and dynamic impact.

The bottom cone design is resistant to centrifugation and shock.

They are packed with a transport medium (inactivated type, preserved type) for the release and preservation of samples to prevent leakage.

The sampling tube has built-in magnetic beads, which are convenient for elution and facilitate the release of more viruses into the virus transport medium.

Before the higher positive rate of PCR detection, the storage solution in the virus sampling tube was Hank’s solution.

Now, the virus sampling tube preservation solution has been upgraded to CellMedical virus preservation solution.

(that is, UTM, recommended by the World Health Organization and the National Influenza Center of China.)

Based on hank’s solution, BSA, HEPES, amino acids, glycerin and other ingredients. A high PCR test is positive.

What is A Covid-19 NP Swab?

What is A Covid-19 NP Swab?

The COVID-19 Swab test is an important part of the anti-epidemic work, and it is extremely important to standardize the operation of sampling techniques.

All sampling operations must be standardized. In order to provide a strong guarantee for the accurate reporting of subsequent nucleic acid testing.

Nasopharyngeal (NP) swabs are the primary sample type for respiratory molecular pathogen testing.

During the 2019 novel coronavirus infectious disease (COVID) pandemic, NP swabs became central to the detection of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2).

Unfortunately, NP swab collection can be very uncomfortable for some patients.

Because when collecting nasal swabs, a relatively long flocked swab, is directly inserted into the nasal cavity of the person being collected.

However, nasal swabs will not cause pain if the operator is appropriate, but some people with sensitive noses or diseases may experience mild discomfort.

Np swab covid test meaning?

Np swab is the nasopharyngeal swab test, which refers to a relatively conventional method for detecting viruses.

Nasal swab testing mainly involves inserting a relatively long sterile flocked swab into the patient’s nasal cavity.

It was then collecting secretions from the nasopharynx through the nasal cavity.

And then testing these secretions in various aspects, such as bacterial culture And drug sensitivity test to determine the source of infection and the type of microorganisms.

Symptomatic treatment according to the test results, and a drug sensitivity test can also be used to determine which drug is more sensitive.

Use the more sensitive drug for treatment.

What should medical staff pay attention to when collecting nasopharyngeal swabs?

All healthcare professionals performing nasopharyngeal swab tests must wear the recommended personal protective equipment (PPE), which should include N95 masks, disposable caps, goggles, protective clothing, latex gloves, and shoe covers.

Nasopharyngeal flocked swabs: performed with the patient sitting upright with the head in an upright position.

What is A Covid-19 NP Swab?

What is A Covid-19 NP Swab?

The subject needs to tilt his head back.

Nasopharyngeal swabs are not along the nostrils, but perpendicular to the face, entering from the nasal passages.

When collecting, do not enter violently when encountering resistance or the subject feels obvious pain.

When taking nasopharyngeal sampling, the operator can stand behind the subject and does not need to look directly at the nasal cavity.

In addition, there is basically no gag reflex, the tolerance is good, and the risk of exposure is relatively low.

After sampling, the individual tested may have a sneeze reflex, immediately use an elbow or a tissue.

A small number of subjects may have a little nosebleed after sampling, which can usually be stopped on their own.

When taking a nasopharyngeal swab, it can stay in the nasopharynx for a longer time in order to obtain a more adequate sample.

Studies have shown that the positive rate of nasal swab samples is higher than that of throat swab samples, that is, the efficiency of nasal swabs for virus swab detection is higher than that of throat swabs.

What can a nasopharyngeal swab detect?

Used for nasopharyngeal sampling for respiratory viruses such as influenza, swine flu, bird flu, and hand, foot and mouth.

Nasal Swab Test

A nasopharyngeal culture

The reasons for false negatives

1. Patient: The virus content may be too low. The nucleic acid swab detection reagent has certain requirements for the virus presence in the infected person. If the virus is too low, existing methods may not detect it.

The onset of new coronary pneumonia patients will go through a process from asymptomatic after infection, to mild symptoms, to severe symptoms.

2. Collection of specimens: false negatives cannot be completely avoided.

Many experts have concluded from practical work that the positive rate of sputum and bronchoalveolar lavage fluid samples collected from the lower respiratory tract is higher than that of oro-nasopharyngeal swabs from the upper respiratory tract; the positive rate of nasopharyngeal swab samples is higher than the Oropharyngeal swab.

Improper collection site, for example, when collecting oropharyngeal swabs, the depth of the collection is not enough;

Nasopharyngeal swabs are not enough deep into the nasal cavity, etc., and most of the collected cells may not contain viruses, which may cause false negatives.

3. Detection reagents: At present, the quality of the reagents on the market may vary.

4. In addition to the test reagents themselves, laboratory specifications will also have an important impact on the test results. Specimen transportation and storage conditions, standardized operations in clinical laboratories, result interpretation and quality control are all key factors to ensure the accuracy and reliability of test results.

Prevent false negatives

Incorrectly performed nasopharyngeal swabs may lead to a greater likelihood of patients receiving false-negative test results.

False-negative results are an important issue to address, as these results can cause patients who are positive for some diseases to unknowingly transmit highly contagious diseases, especially COVID-19, too many others.

Therefore, adequate training of testers on how to perform nasopharyngeal swab tests reliably is critical. Use high-quality detection reagents. learn more.

How To Properly Administer A Covid Swab Test To Your Baby

COVID-19 still plagues all parts of the world, and it will become more serious in spring, so there are still many people who need to do nucleic acid tests.

Do many parents have many questions about nucleic acid testing for children, especially babies, such as how to do nucleic acid testing for 10-month-old babies?

How do nucleic acid swabs test for children?

The nucleic acid test method for 10-month-old infants and adults is the same.

The method of throat swab is used. The throat is sampled.

When sampling, you only need to tilt your head slightly, open your mouth wide, and wait for the medical staff to use a flocked swab.

The swab stick can be sampled.

You may feel a little nauseous during sampling, but it is not particularly uncomfortable in general.

This kind of discomfort is acceptable to basic children, and the sampling process is relatively fast, so parents don’t need to worry too much.

Of course, it is not ruled out that some children do not cooperate. In this case, older children can communicate well, explain the situation, and parents can show the children how to carry out nucleic acid testing; if it is a child who is too young to communicate, then you have to grab it forcibly for sampling.

It should be noted that before going to the hospital for examination, you must make an appointment first, otherwise, it will be a waste of time.

Since different hospitals or testing centres generally have different methods for ordering nucleic acid testing.

It is important to understand the hospital nucleic acid testing process before officially performing nucleic acid testing.

In addition, it is not recommended to eat about two hours before the nucleic acid test.

If you are nauseous during the sampling, you may vomit or spit milk, but this is rare.

Baby swab tests

Baby swab tests

 

  • You bring your child’s safety to a stable place (a blanket on the floor, a changing table, another adult’s arms).
  • Consider wrapping them in a warm blanket to relax and prevent their elbows from helping you.
  • Show them a pacifier (make sure you can adjust their nostrils) if the pacifier will soothe them.

In general, bring the kids to a convenient place where you know them best.

As an adult helper, you can take the kids on their laps.

We recommend keeping your back against the patient’s reason and facing toward the person holding the flocked swab.

Then you can start!

 

The nucleic acid test method for children is the same as that for adults.

The throat swab is to extract the secretions of the respiratory tract for testing.

Because the baby has a problem with cooperation, it is best not to feed the child 2 hours before the nucleic acid test.

During the nucleic acid detection process, children may not cooperate.

If they have just finished eating food, they will vomit, which will affect the nucleic acid detection results.

Nucleic acid testing uses a long throat swab to smear on the back wall of the pharynx.

The medical staff are more skilled and will not cause much impact on the child.

Instructions for use, specimen collection

Note Sterile gloves, protective clothing and goggles should be worn when collecting and handling microbial specimens;

Open the peel bag and remove the flocked swab.

The COVID-19 pandemic has actually added another layer of complexity to the flu season ahead of schedule. COVID and the flu share many similar signs and symptoms, which certainly makes diagnostic screening even more important this flu season.


What is a flu swab test?


Flu is the abbreviation of Influenza. This disease is not unfamiliar to us. It is an acute respiratory infection caused by influenza virus. 


Influenza is very contagious and spreads very quickly. Once you have flu symptoms, you must go to the hospital for relevant examinations in time to determine the type of flu before symptomatic treatment.


Every year when the seasons change, the virus will also increase due to changes in temperature. This period is also the time when we are most prone to getting sick. 


Among them, influenza is a very common epidemic infectious disease. Influenza is familiar to most people, but not very well known to a few people. 


Getting a quick, accurate diagnosis is of course critical to driving treatment decisions.


Influenza testing can be done with blood tests, nasopharyngeal swabs, etc.


How to Test for Flu with a Swab.


How Accurate Is The Nasal Swab
Which Swab Test is More Accurate?


Discovering the right flu test is critical to ensuring accurate results. Using high-quality items—including appropriate swabs, shipping media, and testing devices—can help to properly identify influenza and reduce the potential spread of infection. Influenza testing needs to detect the influenza virus.


 After infection with influenza, the influenza virus usually invades the nasopharynx first, which can be detected by a nasopharyngeal swab. 


Influenza virus can also enter the blood and can be detected by a blood test. Influenza is a relatively serious respiratory infectious disease.


 After the infection, the systemic symptoms are more obvious, such as high fever, general weakness, and sore limbs. 


The recovery of the disease is also relatively slow, and it takes about half a month. 


Each of the influenza tests listed above can be performed using a nasopharyngeal (NP) swab, throat swab, NP swab, nasal or endotracheal aspirate, or saliva test.


Covid Test Throat Swab

To perform an NP flu swab test, follow these steps: 


Choose a flocked swab with excellent absorption and elution, such as CellMedical’s Nasopharyngeal Swab CM-96000N 6″ Sterile Flocked Swab with Breakpoint 90mm. 


With the patient’s head tilted back, slowly insert the flocked swab into the nasal cavity. 


Place the swab directly into the nostril directly back (not up) and at the level of the nasopharynx to the distance determined on the swab handle. 


Rotate the swab approximately 3 to 5 times and hold in place for 5 to 10 seconds to obtain a sample. 


Remove the sampling swab and insert into a virus sampling tube containing 1 to 3 ml of virus transport medium. 


Break the flocked swab along the breakpoint. 


Label the vial with the appropriate customer information.


How long does a flu swab test take? 


Throat swab test belongs to a class of medical test methods. A medical sampling swab is used to take a small number of secretions from the pharynx of the human body, inoculate it in a special petri dish, and then put it into a temperature control device for cultivation. Throat swab test can understand the patient’s condition, oral mucosa and throat infection. As for how long the results will take, depending on the number of people tested, some hours, some a day, some a week.


How accurate is the flu swab test? 


The flu nasopharyngeal swab test is more accurate when the virus load is sufficient. 


This is used to determine whether the human body has the flu. 


But if the test comes back positive, that would require sampling and testing of those who came into contact with the patient. 


It can prevent the spread of influenza, and it is necessary for suspected patients to be properly isolated, placed separately, and tested.


Nasopharyngeal swabs are commonly used clinically to detect viruses. 


That is, take a sampling flocked swab and gently wipe the patient’s nasopharynx, and then take samples for testing.
