Nasal Swab Pcr Test

To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.

This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.

Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.

For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:

1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.

2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.

3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.

4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.

5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.

In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

How much do you know about COVID-19 antigen detection technology?

In late spring and summer of 2020, the COVID-19 epidemic was initially resurgent beyond all expectations, and unexpectedly came back with a strong attitude.

“COVID-19” On August 26, 2020, in order to control the spread of the epidemic.Abbottswab.

In addition, the federal government will spend $760 million to buy 150 million copies of reagents and transport them to nursing homes and schools in about a month.

Antigen detection.

By the end of October 2020, with more similar tests under way and waiting for emergency approval.

Three more antigen test kits have obtained the emergency use authorization (EUA) of the US Food and Drug Administration (US FDA), and the total number has reached 7.

In addition, although the World Health Organization was unwilling to do so at first.

It also approved the use of two antigen detection kits following the emergency authorization of the U.S. Food and Drug Administration in September and October 2020.

In the invention and transformation caused by covid-19 pandemic, detection technology has become a hot spot of biotechnology and engineering innovation.

In addition, more extensive measures such as wearing masks, maintaining social distance, isolating and tracking contacts.

And faster and cheaper screening tests provided by Cell medical provide hope for people’s urgent need to combat this infectious disease and make progress.

Many places in the world that seemed to have controlled the epidemic in the early stage broke out again.

Which shocked public health experts and called on everyone to carry out rapid and frequent testing.

What is a flocked swab？

NYLON FLOCKED SWABS FEATURES:

*Ergonomics and anatomical design:

Patient comfort and cell sample collection efficiency improved at the same time.

nylon flocked nasopharyngeal swab

nylon flocked nasopharyngeal swab

*High-quality sample elution:

Unlike traditional swabs, when the sample does not come out of the mattress core.

Nylon Flocked Swab has an open fiber structure that can immediately transfer the sample cells to the liquid medium.

*Rapid absorption (the improved sample collection)

The static electricity is sprayed on the fibre and fixed evenly and vertically on the top of the coater.

This powerful capillary effect quickly absorbs cell samples.

*Increase analysis sensitivity:

Nylon flocked cotton swab can quickly elute more than 95% of the original sample,

so it is easy to improve the analytical sensitivity.

*Just collect, capture and transport:

Peel off the pouch, collect cell samples,

and clip the applicator shaft into the provided delivery medium or cuvette tube.

*Quantitative volume transfer:

Measurable and consistent absorption and transfer from the patient to the test tube,

without an internal mattress core,

disperses and holds precious samples like traditional fiber swabs.

In contrast, the entire sample remains close to the surface for rapid and complete elution.

*Vertical nylon fiber:

Such as a soft brush, can improve the collection of cell samples.

The capillary interaction between nylon fiber bundles not only facilitates the strong water absorption of cell samples

but also keeps the cells close to the surface, which is more convenient for elution.

*Certified without inhibitors and interferences:

Swabs collected are certified DNase, RNase free, and human DNA free.

They also do not contain any PCR inhibitors.

Certificate of analysis for each batch.

*Ideal for automation:

Compared with the traditional fiber wound swab, the 4n6 DNA swab only released a small amount of fibre during the extraction process.

This avoids the risk of clogging the pipettes and probes used by the liquid handling robot.

1. Sampling is more comfortable and convenient.

Our company uses the existing technology “spraying technology” to vertically attach millions of nylon flocked micro fibers to the head of medical grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of soft brush. Using this soft brush in the sampling process makes the user feel no foreign matter. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

For example, nasal swab, its upper end of the rod is thinner and softer, and its breaking point is longer.

Sterile Flocked Nylon Swab with 80mm Breakpoint.

2. Flocking swab samples release more.

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample remains on the surface to make elution easier. In the traditional cotton swab, most of the samples collected are still captured in the fiber matrix of the head, which is not easy to release or the release amount is small. Flocked swabs have been shown to release up to 95% of the sample, compared with 25% for standard fiber pointed swabs. If the sample size is particularly small, the use of flocking swabs is particularly important.

3. Flocking swab has biocompatibility and is an ideal choice for PCR.

In order to limit the damage to the sample and improve the accuracy of detection, disposable sampling swab is made of better quality nylon flocking swab.

This makes flocking swabs an ideal choice for PCR Swab Test. Therefore, for scientists using PCR technology, the new flocking swab is PCR compatible and does not contain RNase and DNase.

advantages of flocking as a sampling swab

When it comes to sexual sampling swabs, I believe you don’t feel strange at this time.

Because most of the detection tools used for nucleic acid detection are disposable sampling swabs.

Sampling swabs directly contact our human organs, such as nasal swabs and pharyngeal swabs for nucleic acid detection.

So the material selection of sampling head is very important, and the material of sampling head is closely related to subsequent detection. The sampling swab shall ensure the sampling amount and release amount, and the selected material shall not have substances that affect the subsequent detection.

·Compared with the traditional winding swab, the amount of samples collected and released by flocked swab is three times higher, and it will not cause harm to human body.

·The sampling time of flocking swab is 3-5 seconds, which is fast and convenient to improve work efficiency.

Only by extracting samples faster can we complete the collection and analysis more efficiently.

·Moreover, through the directional friction effect of the brush fiber layer,effective collection of samples.

Therefore, the flocking swab is particularly conducive to the collection of trace DNA.

·A large number of clinical experiments show that compared with ordinary sterile cotton swabs, flocking swabs have a better effect on the collection and transportation of clinical microbial samples. This is especially true for those specimens that cannot be submitted for examination in time and placed for too long.

COVID-19 Swab Test |One Minute to Learn about Nucleic Acid Test

So far, the number of confirmed cases of the global epidemic has exceeded 237 million, followed by the recurrence of the epidemic. We must do a good job in COVID-19 testing and strive to defeat the virus at an early date.

1. Why a nucleic acid test? What does it test for?

Nucleic acid swab detection is the direct evidence to find the existence of virus. The novel coronavirus pneumonia virus nucleic acid test positive, indicating that the presence of virus in the subjects, may be infectious.

If the patient has fever, respiratory symptoms or other clinical features of NCP, the patient can be diagnosed as NCP when combined with positive nucleic acid test; if there are no clinical symptoms, the nucleic acid test result is positive, can be judged as asymptomatic infection.

Novel coronavirus pneumonia is a diagnostic standard for new crown pneumonia.

2. Nasopharyngeal swab test and oropharyngeal swab test, which test method is better?

As we all know, nucleic acid detection generally adopts pharyngeal swab detection. Pharyngeal swab testing includes nasopharyngeal swab testing and oropharyngeal swab testing. The difference between the two lies in the different sampling positions, but there is no essential difference. Most medical institutions use oropharyngeal swab detection, because this detection method has less discomfort and is more convenient for sample collection.

3 .what are the precautions before and after COVID-19 Swab Test?

Before testing;

Get your ID card ready before you go out!

Wear masks correctly without fasting;

Try to avoid eating in the first 2 hours to avoid vomiting and other discomfort;

Try not to drink water, drink, smoke, drink or chew gum in the first 30 minutes;

When sampling, reduce swallowing action, swallow less saliva and don’t clear throat;

We should inform the testing personnel in advance whether they have a history of nasal surgery, bending of nasal septum, blood diseases, throat diseases or taking anticoagulants;

Before testing, remove the mask after the medical personnel give a signal, wear it immediately after sampling, and prepare a spare mask for easy replacement at any time after pollution.

Testing;

Consciously queue up and keep a distance of more than one meter;

When collecting oropharyngeal swabs, tilt your head back, relax as much as possible, breathe deeply, and open your mouth to make an “ah” sound, which is helpful to complete the sampling quickly;

The nose may be itchy during the collection of nasopharyngeal swabs. If you sneeze, cover your mouth and nose with paper towels or elbows immediately;

During the detection, try not to touch the detection platform and other articles, and do not touch the protective clothing of the collection personnel.

After detection

Leave the site immediately after sampling, and do not spit or throw garbage at the collection point and surrounding areas;

The inspectors shall pay attention to hand hygiene before and after the test. They can wipe their hands with hands-free disinfectant, hands-free alcohol, disinfection cotton, etc.

4 How can nucleic acid detection alleviate the discomfort of sampling?

Nasopharynx 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 shall cooperate with the sampling personnel as much as possible, relax as much as possible, and do not over move the head to avoid scratching the mucosa with the sampling swab.

Mouth Swab VS Nasal Swab

Mouth Swab VS Nasal Swab

Mouth Swab VS Nasal Swab

Recently, COVID-19 is prevalent worldwide.

It is one of the most serious public health problems in the world.

The diagnosis of COVID-19 requires the combination of epidemiological history, clinical manifestations and laboratory examination, especially the examination of pathogenic pathogens.

It is an important basis for the diagnosis of New Coronavirus disease.

The diagnosis of COVID-19 needs to be checked by nucleic acid. If we can detect the virus, we can diagnose the disease.

The new crown vaccine is mainly used for the examination of the secretion. The most common method is to check the nasal swabs and mouth swabs.

The secretion of nasopharynx is used for nucleic acid detection. If there are positive findings, we can diagnose the disease.

There are certain differences between Mouth Swab VS Nasal Swab.

First, there are certain differences in the methods and parts adopted. 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.

Secondly, there are certain differences in the impact of nasal swabs and pharyngeal swabs on patients. Relatively speaking, nasal swabs are not easy to be accepted by patients. After entering the nasal cavity, they often need to enter a certain depth before they can effectively take samples. For patients, it may cause local discomfort. Pharyngeal swabs enter from the mouth and take secretions from the throat, It may also cause irritation such as nausea.

In addition, the positive rate of samples taken from pharyngeal swabs and nasal swabs is generally not much different, but for pharyngeal swabs, there may be some differences due to the influence of some oral factors.

However, at present, pharyngeal swabs are more widely used in clinic, and even some samples need to be collected together with pharyngeal swabs and nasal swabs, There is a certain possibility to improve the positive rate.

How to Obtain a Nasopharyngeal Swab Specimen

As a non-invasive operation, nasopharyngeal swab sampling is the first choice for diagnosis, monitoring and differential diagnosis of New Coronavirus pneumonia. Its sampling randomness is high. However, the sampling personnel may have false-negative test results due to the different location, strength and time of scraping samples, which may have an adverse impact on the epidemic prevention and control. During the operation, the patient choked and splashed to produce an aerosol, which is very easy for medical staff to have occupational exposure.

This paper mainly explains in detail the protection of medical staff when collecting nasopharyngeal swabs, the collection, packaging and transportation of nasopharyngeal swabs, as well as the patient’s body position, operation methods, collection parts and precautions during specimen collection.

Effective communication and nurse-patient cooperation help the successful collection of nasopharyngeal swabs.

Before the operation, the degree of cooperation of patients should be effectively evaluated. Inform the patient of the collection purpose and precautions in advance.

Clinicians should be cautious if the patient has recent nasal trauma or surgery, a significant deviation of the nasal septum, or a history of chronic obstructive nasal patency or severe coagulation disease.

Standard protection is the foundation of successful nasopharyngeal swab collection

Operator preparation: first, wear protective clothing, wash hands with soap and water (or alcohol), and wear a pair of non-sterile gloves. Then, according to the recommendations of the Centers for Disease Control and prevention, wear an N95 or higher protective mask. Finally, wear a face mask to protect your face and eyes.

Swab Nasal Covid Sampling preparation: operating platform; Sampling materials, including nasopharyngeal test swab, VTM kits, inspection sheet and bar code, transport bag and hand disinfectant, to ensure the sterilization effect and validity period.

Obtain a Nasopharyngeal Flocked Swab Specimen

Nasal swab specimen collection method.

(1) Wet the flocked swab in normal saline.

(2) Measure the distance from nostril to ear root with a swab and mark with your fingers.

(3) Insert the swab into the nostril in the direction perpendicular to the nose (face) until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then rotate it gently for 3 times.

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

(5) Tighten the tube cover, mark it, put it into the specimen bag and seal it.

(6) If it is necessary to collect from two nostrils, one swab should be used respectively.

(7) Store at 4 C or on ice (short term storage).

CDC recommends that all patients suspected of infection with COVID-19 use masks.

Ask the patient to take off the mask and wipe the nose with a paper towel to remove excessive secretions from the nasal cavity.

Remove the cotton swab from the package. Tilt the patient’s head back slightly so that the nasal tract is more accessible.

Let the patient close his eyes to reduce the slight discomfort caused by the operation.

Gently insert the swab into the nasopharynx along the nasal septum until resistance is felt.

Tips for nasopharyngeal swab sample collection.

The nasopharynx swab is inserted quickly. Do not hesitate. Some patients are intolerant to the operation of probing the nasopharyngeal swab into the nasal cavity, resulting in tears, foreign body feeling, etc. before the operation, ask the patients to inhale deeply in order to avoid choking and coughing.

When the cotton swab reaches the expected depth, do not continue to go deep, so as not to cause nasal mucosal damage and bleeding. During the stay, use finger strokes with the patient to read the seconds. It can distract attention, eliminate tension and motivate patients to ensure successful collection.

Never allow the patient to fully raise his head and bend the swab, which will lead to incorrect retention position of nasopharyngeal swab head and ultimately affect the accuracy of specimen collection results.

The operator can select the left / right side of the operator according to his left and right hands, and stand on the patient’s head and shoulder for operation. The patient’s head does not need to be biased to the opposite side. It is difficult to control the entry angle of the flocked swab when facing the side head, which may cause mucosal irritation. For patients with excessive tension, the operator can hold the patient’s hand and give comfort.

Detection of viral nucleic acid sequence based on reverse transcription polymerase chain reaction (RT-PCR) is the main means for large-scale screening of new coronary pneumonia.

Generally, nucleic acid detection technology has the characteristics of early diagnosis, high sensitivity and specificity.

And it has the advantages of sample collection and preservation, personnel operation, nucleic acid extraction.

The performance of the kit is the cause of false negative or false positive test results.

Flocked swabs are the main samples for PCR. In the selection of raw materials, flocked glue plays a key role in the collection and release efficiency of swabs. Whether to use high-quality aqueous flocking glue is the main factor affecting the water absorption and hydrophilicity of fluff. The experiment is to compare the sample collection effects of swabs flocked with different glues.

What is a flocked tip swab？

The top of the flocking swab is a nylon fiber structure.

Nylon fibers are deposited on the surface of plastic rod in a certain direction by electrostatic field to form brush layer.

The layers are completely parallel and perpendicular to the inner rod surface.

Flocked tip swab brush head can effectively collect samples.

Flocked tip swab factory Product advantages.

The flocked swab can completely capture the cell sample through the directional friction effect of the brush fiber layer.

The capillary movement between the nylon fibers at the front end of the flocking swab can form a strong hydraulic pressure for absorbing liquid or cell line samples.

Cell samples can also be evenly and neatly concentrated on the near surface of brush fibers, so more than 95% of the samples can be released finally.

Cell Medical (Dongguan) Co., Ltd.  has many years of experience in medical application molding and flocking treatment heads and swabs.

Our flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability.
