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.

Nasal Swabs for Sample Collection

I believe many people are very curious.

There is already a throat swab.

Why do you have to do a Nasal swab?

In the actual anti epidemic work scene, in fact, medical staff have a set of scientific judgment basis for collecting oropharyngeal swabs or nasopharyngeal swabs.

Because the nose swab only needs to expose the nose during the sampling process, the probability of exposure to the virus environment is low.

For high-risk people, such as asymptomatic infected persons, entry personnel or suspected people being isolated.

Nucleic acid detection with nasal swabs can reduce the infection risk of collectors, and the psychological acceptance of samplers.

That is, medical personnel, is also higher.

For the nucleic acid detection and screening carried out in the community, due to the more emphasis on rapid screening, the use of oropharyngeal swabs is more convenient and fast.

If discomfort or slight bleeding occurs during the collection of nasopharyngeal swabs, it is generally not treated.

After a period of time, the discomfort will disappear automatically.

If it is really uncomfortable, it can be properly cleaned with normal saline.

But do not wash too much, too much cleaning may bring more pollution.

Why is flocking swab used in nasal swab PCR test？

In order to improve the swab collection efficiency and meet the needs of end consumers for high-quality products.

Cell medical’s Flocked swab came into being.

Innovative jet implanted nylon fiber technology to maximize the sampling efficiency of the sampling swab.

The nylon fiber is vertically and evenly attached to the surface of the swab head, greatly increasing the collection and release efficiency of cell and virus samples.

Improve the analysis sensitivity, no sample residue, speed up the sample processing process, and the unique breakable design of ABS plastic rod.

It is applicable to the collection of cervical, nasopharynx, oral throat, forensic samples, virus, DNA and other samples.

◆ upright nylon fiber is like a soft brush, which can collect more specimens.

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.

◆ it has outstanding sample collection and release ability, can quickly adsorb micro samples, and has high release aging rate. The increase of the number of target cells is helpful to improve the sensitivity of rapid diagnostic test.

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.

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.
