How do avoid damage to the nasal cavity through nasal swab sampling for nucleic acid detection and antigen detection? Rhinitis patients should pay attention to what?

Standardized collection methods for nasopharyngeal swabs :

Nasopharyngeal Swab

Nasopharyngeal Swab

1. The sampler lightly supports the head of the person to be collected with one hand, and sticks the swab into the nostril with the other hand.
And slowly penetrates backward along the bottom of the lower nasal passage. Because the nasal passage is curved, do not use excessive force to avoid traumatic bleeding.
2. When the top of the swab reaches the back wall of the nasopharyngeal cavity, gently rotate it for one week. (If you have a reflex cough, it should stay for a while). Then slowly take out the swab, and immerse the swab head in the matching test strip. In the sampling tube of the virus transport medium.
The nasopharyngeal collection method collects a sample from the nasopharynx, which is the upper part of the throat behind the nose.

Nasopharyngeal Swab Pcr Test

Nasopharyngeal Swab Pcr Test

In this test, a small pointed flocked swab is inserted into the nostril parallel to the chin until resistance is felt.

Inserted no deeper than half the distance between the nostril and the ear.

The swab is then swirled a few times while remaining in place, and then slowly removed while gently swirling.

If the flocked tip of the swab is completely saturated with the sample, it may not be necessary to collect samples from both nostrils.

This method is often less comfortable for the patient but is generally not considered painful.

This method is not recommended for self-testing and should only be performed by a healthcare practitioner.

Swabs for use in the nasopharynx are designed with a micro-tip made of ultra-fine flocked material and a thin, flexible handle usually made of polystyrene.

Standardized collection methods for nasal swabs (anterior nasal swabs):

Anterior Nasal Swab

Anterior Nasal Swab

1. The collected person first used toilet paper to remove the snot, and then tilted his head slightly.
2. The sampler lightly supports the head of the person to be collected with one hand, holds a swab with the other hand and sticks it into one nostril. And slowly goes back along the bottom of the lower nasal passage for 1-1.5 cm. And then sticks to the nasal cavity and rotates at least 4 times. (The residence time is not long. less than 15 seconds). Then repeat the same procedure in the other nasal cavity using the same swab.
3. After slowly taking out the flocked swab, immerse the swab head in the sampling container containing the preservation solution that comes with the test strip.
Precautions:

  • 1-1.5cm deep into the nasal cavity (about 1cm for children).
  • Rotate 4-5 times against the nasal cavity (time not less than 15 seconds).
  • Bilateral nasal collection from the same swab.

Standardized collection methods for oropharyngeal swabs (pharyngeal swabs):

When Taking An Oropharyngeal Swab

Oropharyngeal sampling swab

1. The head of the person being collected is slightly tilted, the mouth is wide open, and the mouth shape is “ah”, exposing the pharyngeal tonsils on both sides;
2. Pass the swab across the base of the tongue, and wipe the pharyngeal tonsils on both sides of the subject with slight force back and forth at least 3 times.
And then wipe the posterior pharyngeal wall up and down at least 3 times.
 And immerse the swab head in the preservation solution provided with the test strip. in the sampling container.

 Why do nucleic acid testing (PCR swab test), and what can be detected?

Nucleic acid testing is to find direct evidence of the presence of the virus.
A positive nucleic acid test for the new coronavirus pneumonia indicates that the subject has the virus in the body and may be infectious.
 If accompanied by fever, respiratory symptoms or other clinical characteristics of patients with new coronary pneumonia, combined with a positive nucleic acid test, a patient with new coronary pneumonia can be diagnosed; if there are no clinical symptoms and a positive nucleic acid test result, it can be determined as an asymptomatic infection. Therefore, nucleic acid detection is of great significance as a standard for diagnosing new coronary pneumonia.

Nasopharyngeal swab test and Anterior Nasal Swab test, which is better?

As we all know, nucleic acid detection generally takes throat swab detection, and throat swab detection is divided into nasopharyngeal swab detection, Anterior Nasal Swab, and oropharyngeal swab detection. The difference between them is that the sampling sites are different, but there is no essential difference. Most medical institutions use oropharyngeal swab testing because this testing method is less uncomfortable for the sample and more convenient for sample collection.
For the sampling of the new crown antigen professional version and home self-test version. Because this method is less invasive, and generally more comfortable for the patient.

Nasopharyngeal swabs are suitable for collecting and transporting virus specimens such as covid-19, clinical influenza, avian influenza, hand, foot and mouth disease, and measles, as well as specimens of chlamydia and mycoplasma.

In order to respond to this round of the epidemic, stop the spread of the virus and reduce the risk of infection.

At present, we have successively carried out multiple rounds of swab testing for the new coronavirus.

Why are oropharyngeal swabs and nasopharyngeal swabs performed in covid swab testing?

covid flocked swab

covid flocked swab

Nasopharyngeal swab refers to the collection of secretions from the throat or nose of a patient with a specialized sterile flocked swab.

We generally use nasopharyngeal swabs to detect viral nucleic acids, viral antigens, and bacterial cultures.

The collection site of the oropharyngeal swab should be the pharynx and tonsils.

The basic steps of collecting the pharyngeal swab are to tilt the patient’s head back, open the mouth wide, and remove the secretions on the surface of the nasal cavity.

The sampler fixed the tongue with a tongue depressor and used polyester or calcium alginate test paper to cross the base of the tongue.

Wiped the posterior pharyngeal wall and the lateral wall of the tonsillar recess 3-to 5 times to collect mucosal cells.

Remove the swab gently, avoiding contact with the tongue, uvula, oral mucosa, and saliva, and insert the swab back into the sampling device or a suitable transport device.

Nasopharynx swab vs oropharyngeal swab

Nasopharynx swab vs oropharyngeal swab

The main difference between the two lies in the sampling method and sampling location.

The detection rate and accuracy of nasopharyngeal swabs are higher than those of oropharyngeal swabs.

Still, nasopharyngeal swabs are more complicated and difficult to operate, and people with nasal diseases。

Such as rhinitis and nasal polyps will not easily adapt, Bleeding may occur during the collection process, so the collection speed is slow.

Compared with nasopharyngeal swabs, oropharyngeal swabs are fast, simple and easy to collect.

And the detection rate can meet the requirements.

Therefore, oropharyngeal swabs are often used in large-scale screening.

For key groups or middle- and high-risk groups.

Required to collect nasopharyngeal swabs, or even stool and blood samples.

In addition to nasopharyngeal swabs and oropharyngeal swabs.

There are also detection methods such as serum, anal swabs, deep cough sputum, nasopharyngeal or respiratory tract extracts, and bronchial lavage fluid.

In general, the method of sample collection will be determined according to different populations and different needs.

Nasal Swab Covid Test

Some people need to be tested for COVID-19 with a quick swab.

The pros are sure: If it is possible for you to test both the nose and the throat at the same time.

Officially, the FDA follows inspection guidelines. Simply put, observe the subtests consistently during this period.

COVID19 test flocked swabs to exteriors.

What is a nasal swab?

COVID Swab test

COVID Swab test

A nasal swab is a test that checks for viruses in the nasal cavity, and the result is a test that checks the nasal cavity by a method.

Because of rhinitis in the nasal cavity, sinusitis, sinusitis, nasal cavity in the nasal cavity and other problems.

There are several respiratory infections, including the flu, COVID-19. A nasal swab can help your doctor determine the type of infection you have and which treatment is definitely best for you.

The test can be done by taking a sample of cells from your nostrils or nasopharynx.

A nasopharyngeal flocked swab is the uppermost part of the nose and throat.

Other names: Anterior nostril examination, turbinate swab, NMT swab, nasopharyngeal culture, nasopharyngeal swab

Why do I need a nasal swab?

01The positive detection rate of nasal swabs is higher.

When using a throat swab to detect the new coronavirus, the base of the tongue will instinctively prevent the cotton swab from going deep, and the cotton swab is not easy to reach the back wall of the pharynx. . The nasal swab is easier to reach the tested site and can stay in the nasopharynx for a long time, and the test results are more accurate. Students returning to school from the north and south of the river and by various means of transportation require us to improve the accuracy of testing in a responsible attitude to everyone’s health.

02Nasal swabs are safer for nucleic acid collection personnel.

During the nasal swab test, the tested person needs to wear a mask with only the nostrils exposed; while for the throat swab test, the tested person needs to open his mouth wide, and the exposed area is large. If the tested person coughs and retches, the nucleic acid tester may face a greater risk of infection. Once the testers are infected, the risk may spread to a wider range of people.

03 Throat swabs may be more uncomfortable than nasal swabs.

Throat swabs are collected across the base of the tongue to the posterior pharyngeal wall, tonsillar recesses, sidewalls, etc., and repeatedly wiped 3 to 5 times to collect mucosal cells. In response, nasal swabs were relatively less irritating to the mucosa.

The entire nasopharyngeal swab process:

What to do before swab test

nasopharyngeal swab

You will throw your head back.
Your healthcare provider will insert the swab directly into your nostril until it reaches your nasopharynx (the top of your throat).
Your supplier will rotate the swab and remove it.
Do I need to do any preparation for the exam?
For nasal swabs, you don’t need any kind of special preparation.

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.

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.

Cell medical nasal swab adopts jet nylon fiber implantation technology, which is first-class in the domestic and foreign markets. Such material can absorb more samples.

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.

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.

The benefits of flocked swabs for COVID-19 viral collection.

1. Sample collection process: The unique structure of the front end of the flocking swab can greatly increase the number of samples collected.

2. Sample dissolution process: The brush-like layer structure can release almost all collected samples. There are more advantages for the collection of trace DNA.

3. According to different analysis items, the corresponding soft or brush texture swabs have reached the maximum collection.

4. Disposable sterile sampling swab rod with breaking point.Learn more

5. Flocked swab technology improves the adsorption/release of samples and the sensitivity of the analysis.

6. The front flocked swab sampling is more precise and suitable for extracting more cells from the nasopharynx.

7. Packed in a transparent plastic tube to avoid biological pollution.

In short, the upright nylon fibre is like a soft brush, which can collect more cell samples. The capillary action between nylon fibers enhances the load of aqueous samples, and the samples are concentrated on the surface of the swab, which is easier to elute. Nylon flocking swab can absorb and release more samples.
