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

Sterile Sampling Swab |Precautions for producing sterile sampling swabs

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.

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

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

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.

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.

Novel coronavirus pneumonia and influenza were the most frequent period of communication in winter and spring. The most important way to control the epidemic is to select new patients with new crown pneumonia from many respiratory patients.

About viral transport medium with swab.

Swabs and virus transport media are a transport and collection system for long-term freezing, transport and collection of clinical specimens containing viruses.

The main species of organisms usually transported through this medium include chlamydia, urea plasma organisms and mycoplasma.

With the outbreak of COVID-19 pandemic, swabs and virus transport mediums were used to freeze and collect SARS-CoV-19 virus samples.

Rub a swab on the skin or vesicles to collect virus samples. The collected samples are then sent to the laboratory with transport media.

Why do swabs need virus transport media

After virus collection, the traditional method can not be detected by PCR immediately. The virus itself will quickly dissolve in vitro and affect subsequent tests.

what is the flocked swab?

Flocked Swab Meaning

Since the outbreak of COVID-19, the word “nasopharyngeal swab” has become a high-frequency word we talk about every day.

In recent months, the new crown pneumonia epidemic broke out again in countries all over the world. It’s worrying to watch the data released by WHO every day!!!

Flocked swab material

The flocked swab is made of nylon fiber flocking technology, and the front end is coated with nylon short fiber fixed vertically so that there is no absorption hole in the sampling area of the whole sampling swab, and the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.

Traditional cotton swabs can not completely collect and elute samples while flocking swabs can elute 95% of samples. Therefore, the use of flocking swabs has great advantages for various sample collection applications.

The flocked swab is to deposit nylon fibres on the surface of the medical ABS rod in a certain direction through an electrostatic field to form a brush layer.

What is the purpose of flocked swabs?

Flocking swabs are the best choice for nucleic acid detection because they can better collect cell or biological samples at the collection site and release samples quickly.

Application: forensic medicine, DNA, microorganism, virus sampling, Oral swab, nasal swab etc.

What are flocked swabs used for in COVID-19?

The autumn and winter communication season is a period of the high incidence of common cold and influenza, and the most important means to control the epidemic situation is to select real patients with new crown pneumonia from a large number of respiratory tract patients.

At present, the most effective and widely used new crown sampling methods are nasopharyngeal swab and oropharyngeal swab sampling.

The upper respiratory tract of human body includes nasal cavity, pharynx and throat.

That is to say, if people are infected with COVID-19, they can extract the nucleic acid of the virus in the nasal cavity, pharynx and larynx in 96 hours.

Therefore, we usually sample these locations in the rapid detection of new crown nucleic acids.

How to collect a nasopharyngeal swab?

Nasal swab sampling process

The first step is to collect secretions.

First, the medical staff will use a pharyngeal swab to wipe the subject’s nasal cavity or throat tonsils to collect salivary secretions.

The second step is to reserve samples.

After collecting the sample, immerse the nasopharyngeal swab in the preservation solution and screw on the tube cover to retain the sample.

The third step is to send samples for inspection.

Then, put the samples into clean sealed bags and send them to relevant parts for testing.

The fourth step is nucleic acid extraction.

Relevant departments will send the samples to the designated laboratory for nucleic acid extraction experiment.

Step 5: fluorescent PCR nasopharyngeal swab.

After collecting nasal samples, the experimenter uses fluorescent PCR to detect whether there is amplification reaction.

That is, to judge whether it is negative or positive.

Step 6:Finally, Receive test report.

Finally, according to the fluorescent PCR reaction results of nucleic acid detection, the nucleic acid detection vehicle inspection report is obtained, and I can query the results.

Sampling swab material

The sampling swab used for nasopharynx collection consists of a narrow rod made of a short plastic rod, one end of which is covered with an absorbent material. Such as cotton, polyester or flocked nylon.

The swab used for virus sampling should directly contact the sampling part.

The material of the sampling head is closely related to subsequent detection.

And the material requirements of virus sampling swab will be very high.

The virus sampling swab head shall be made of polyester (PE) synthetic fiber or artificial fiber.

Forbidden to use calcium alginate sponge or wooden swab (including bamboo stick).

However, calcium alginate and wood components can also absorb proteins after immersion in the preservation solution, and even inhibit the subsequent PCR reaction.

What are the advantages of using flocked sampling Nasopharyngeal swabs?

1. Flocked swabs provide better sampling.

Flocking swabs are a good choice for rapid diagnostic tests because they can better collect cells or organisms at the collection site and ensure the rapid release of the whole cell.

2. Enhanced diagnostic sensitivity.

Professional flocked technology turns each fiber into a velvet like swab, thus creating hundreds of thousands of contact points to better collect and release the collected samples.

Compared with non aggregated swabs, the increase in the number of target cells helps to improve the sensitivity of rapid diagnostic tests.

3. Rapid elution.

Their stable and reliable performance and excellent absorption and elution ability.

4. Easy handling and transportation.

sterilized and packaged separately, and the sterile swabs.
