Nucleic acid detection is to collect Nasopharyngeal swabs, sputum or lower respiratory tract specimens, real-time fluorescence RT-PCR detection of New Coronavirus nucleic acid, if positive, can be diagnosed with New Coronavirus infection, which is the basis for the diagnosis of new type of pneumonia. In addition to detecting the nucleic acid of the virus, it can also detect whether the virus in the specimen is highly homologous with New Coronavirus. If so, it can be diagnosed as New Coronavirus pneumonia. The virus is highly infectious and has the characteristics of human to human transmission, but the virus is sensitive to temperature and sunlight and ultraviolet rays.

Nucleic acid detection and collection method:

(nucleic acid detection nasal swab)

1. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nostril. The collector can stand on the side of the collector to reduce occupational exposure caused by coughing and sneezing and relieve the collector’s pressure.

2. Measure the distance from nostril to ear root with a swab and mark it by hand.

3. Gently insert the swab into the nostril in the direction perpendicular to the nose (face) through the nasal cavity, with a sense of touching the wall 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 pipe cover, mark it, put it in a plastic bag and seal it.

6. Send the samples for examination in time

About flocked swab specimens

Nasopharyngeal sampling swabs are composed of nylon short fiber pile head and medical grade ABS plastic rod.

The nylon short fiber acts like a soft brush, which can effectively improve the collection of cellular material;

the capillary movement between the fibers forms a strong hydraulic pressure, thus ingesting the liquid sample;

at the same time, the sample clings to the surface of the swab and is easy to wash off.

Cell medical (Dongguan) Co., Ltd. Sterile flocked swabs collect and elute samples more effectively than any other disposable swabs on the market.

The high-quality fiber and swab physical manufacturing process produce sterile flocking swabs, which is an ideal choice for rapid diagnostic testing.

The rapid release of whole cells and the ability to better collect cells make these swabs the perfect specimen collection for any laboratory or research center.

The ideal collection device must be able to absorb and release samples and maintain their activity.

This is why flocking cotton swabs innovate sample collection equipment.

Sterile flocked swabs collect and retain sample vitality, provide better sample yield, and allow rapid release of samples into liquid media.

Attention

1.The insertion direction of the swab is perpendicular to the face of the subject, not along the nostril.

2.When there is resistance when the swab enters, it shall retreat slightly. Under the condition that the subject tolerates it, readjust the angle before continuing to insert, and do not insert violently.

Sterile Sampling Swab |Precautions for producing sterile sampling swabs

Disposable sterile sampling medical swab, referred to as sterile swab.

Usually, sterile swabs have a collection material on the stem or at the top of the stem, which can be natural or synthetic. Such as polyester, flocking, etc.

The sterile swab material produced and sold by cell medical (Dongguan) Co., Ltd. is flocking.

The proprietary flocked process optimizes collection and elution, and the breakpoint forming handle can better help break, which is in line with ergonomic design.

Usually, the user holds the stem and wipes the collected material on the surface to collect the sample.

Swabs are sterile to maintain the integrity of the sample.

Usually, there is a resealable sterile container or bag to preserve the integrity during processing and transportation to the laboratory.

Including Covid-19 sampling, sterile workers, food producers and crime scene investigators.

For virus collect samples.

The material, size and shape of the sterile swab head may be different, such as round or pointed.

Some users need to collect products aseptically.

They collect samples from people, animals, even plants and other organisms, while others collect samples from inert surfaces, including furniture such as crime scenes and food processing tables.

Many times, The type of sample required determines the type of sterile swab selected by the user.

Sterile swabs may contain sterile water, which is the only acceptable water for laboratory studies.

Sterile swab manufacturers provide dry and wet swabs.

Usually, they pack sterile swabs in sterile packaging, such as paper, plastic or plastic coated paper covers.

Many manufacturers provide packages that are gamma irradiated and sealed to protect the integrity of swabs.

Some swabs are tubular and may contain liquids such as sterile water, sterile saline, or sodium chloride.

The user should check with the laboratory preparing to process the sample to know what type of swab or solution to use. For many applications, maintaining sample integrity is as important as using sterile swabs.

Many places use sterile swabs to monitor the environment or work area, control infection and its transmission, and monitor health management plans.

These include hospitals and medical institutions, food and drug processing facilities, and animal care facilities, such as veterinary clinics and zoos.

Materials for nasopharyngeal sampling swabs – manufacture

During the sampling process of the COVID-19, the pharyngeal swab is in direct contact with the sampling site, and the material of the sampling head is closely related to the subsequent detection.

The sampling swab head: made of flocked swab or artificial fiber.

Prohibited :calcium alginate sponge swab (including bamboo swab) .

Cotton products can not be used for the head of the swab, because the cotton fiber has strong adsorption on protein and is not easy to elute into the subsequent preservation solution;

The broken wooden stick or bamboo stick containing calcium alginate and wooden components will also adsorb protein and even inhibit the subsequent PCR reaction.

Recommended:PE fiber, polyester fiber, polypropylene fiber and other synthetic fibers  as the materials for manufacturing the swab head.

It is not recommended to use natural fibers such as cotton or nylon fibers, because nylon fibers (similar to toothbrush heads) have poor water absorption, which will lead to insufficient sampling and affect the initial inspection rate.

Pharyngeal swab material: prohibited! calcium alginate sponge.

Viral Transport Medium Tube

Whether nucleic acid detection or virus detection, Viral Transport Medium Tube and Sampling Swab play a great role.

Sampling swab is used to collect virus samples, while virus preservation solution plays the role of preserving these virus samples.

Which not only ensures the integrity of nucleic acid virus, but also facilitates the later detection accuracy.

How many virus preservation solutions are there? What are the functions and differences?

At present, there are two kinds of virus preservation solutions on the market, namely inactivated virus preservation solution and non inactivated Viral Transport Medium.

Non-inactivated  Viral Transport Medium can protect the protein and nucleic acid of the virus.

Inactivated Viral Transport Medium usually contains the cleavage salt of inactivated virus to cleave the protein and protect the nucleic acid.

Specific uses of virus sampling tube:

1. The virus sampling tube is generally used for nucleic acid extraction and later virus isolation of influenza virus, hand, foot and mouth virus and rubella virus in clinical patients. The amount of liquid required is usually 35m or 5m. (with nucleic acid detection kit and spore culture medium)

2. For the collection and short-term transportation of avian influenza virus in the external environment. The amount of liquid required is usually 6ml.

3.  For daily monitoring and sampling of poultry, pigs and other animals. The amount of liquid required is usually 15m.

4. For short-term preservation of virus samples. (2-8 ℃ for 48 hours) for necessary cell culture.

5. Used for long-term preservation of virus samples (- 70 ℃ – 196 ℃ for one year) for necessary cell culture.

6. To collect clinical respiratory virus rapid detection kit.

7. To collect clinical samples of mycoplasma, chlamydia and Ureaplasma.

8. To transport tissue samples from the sampling site to the detection laboratory for necessary cell culture.

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

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.

Oral Swab Stick

Oral Swab Stick

Posted on by

Oral Swab Stick-Oropharyngeal sampling swab.

COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.

Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.

Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.

The results of COVID-19 nucleic acid test are also useful.

What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?

Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.

For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.

What is the difference between Oral Swab Stick and Nasal Swab?

Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.

What are the advantages of nasopharyngeal swabs?

It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.

Can a positive oral swab stick confirm COVID-19?

The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.

After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.

Patients with positive nucleic acid test of new crown must be isolated and treated.

Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.

How to sample oropharyngeal swabs?

First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.

The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.

According to the personal experience of colleagues: slightly disgusting, but completely acceptable

The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.
