What elements should a good sampling swab meet？

2021-11-04

In the collection of virus samples, small sampling swabs are always ignored, and people often ignore the judgment of its quality. However, the sampling swab is the “vanguard” in the whole nucleic acid detection process. It is the first area to contact the virus. It can be said that it controls the “lifeblood” of the whole nucleic acid detection process.

sampling swab-flocked swab

Cell medical (Dongguan) believes that a good sampling swab should have three elements——

1: more samples. That is, the virus samples collected by the sampling swab should be as many as possible.

2: release more. That is, the virus samples collected by the sampling swab should be released into the sampling solution as much as possible.

3: excellent design. That is, the design of sampling swab shall not interfere with the nucleic acid detection in the last link.

It is well known that after large-scale nucleic acid screening, the previously commonly used winding swabs were eliminated, and flocking swabs that are easier to collect release samples were used.

However, it is not enough to unify the material.

The design of flocking swab is also very exquisite in structure.

Different nylon fiber arrangement and density determine the difference of sample collection and release.

A good swab can avoid missing inspection to a greater extent.

Whether nucleic acid detection or virus detection.

Universal Transport Medium (UTM) and NP Flocked Flexible Swab sampling swab play a great role.

NP Flocked Flexible Swab : Used to collect virus samples.Nasopharyngeal sample.

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 Universal Transport Medium are there? What are the functions and differences?

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

Inactivated Virus Transport Medium :Use to lyse and inactivate the virus.

It can protect the tester from the second infection of the virus.

Stored at room temperature for a relatively long time, saving the cost of virus samples and transportation.

The purpose of non inactivated virus preservation solution is to retain the protein shell of the virus and the nucleic acid DNA or RNA of the virus, so as to ensure the integrity of the nucleic acid of the virus sample in the process of submission for inspection.

Although there will be a certain infectious risk in case of misoperation, this preservation solution maintains the originality of the virus sample to the greatest extent and is a cultured virus transport medium.

Noted:long-term storage requires strict low-temperature storage after sampling.

Relatively speaking, the non inactivated virus preservation solution has higher requirements for the laboratory, higher sensitivity and more applications. But it is relatively easy to be infected.

As long as there are no problems in sampling and detection operations, there will be no risk problems.

How to select inactivated and non inactivated virus preservation solutions cannot be generalized, We should choose according to different needs, and the price determines the quality.

Don’t be greedy for small things and lose big ones.

The experimental results are as follows: the virus can be isolated within 48 hours when the virus is preserved with cell medical virus preservation solution at 2-8 ℃ or room temperature.

Principle of virus collection and precipitation with flocking swab?

The unique structure of the top of the flocking swab can almost completely extract and precipitate a small amount of DNA. Therefore, the flocking swab has more obvious advantages in micro DNA collection.

(1) Sample collection effect is good:

(1)Through the directional wiping effect of brush fiber layer.

(2) More than 95% sample release rate,near surface of the brush fiber is conducive to collecting samples.

(3) The capillary movement between the nylon fibers at the top of the flocking swab forms a strong hydraulic pressure. To absorb liquid or cell samples.

Nasal Swabs for Sample Collection

Posted on 2021年10月26日2022年3月22日 by Dr. Lee

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.

◆ flocked swab has obvious advantages in nasopharyngeal sampling and microbial sampling, especially in the collection effect of virus and DNA.

◆ 100000 class purified environment, strict production process conditions, and production under ISO13485 quality control and product CE requirements. No DNase and RNase, no endotoxin, no cell inhibitor.

How to do a Nasopharyngeal Swab

How to do a Nasopharyngeal Swab?

Nasopharyngeal Flocked Swab

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.

Nasopharyngeal swab price：Welcome to email:flockedswabs@gmail.com

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

swab test nasal swab

1. With the aid of tongue depressor, the collector opens his mouth and makes an “ah” sound. The palate is lifted up to expose the posterior pharyngeal wall. The swab crosses the root of the tongue to reach the pharyngeal stenosis lesion, and quickly wipe the palatal arch, pharyngeal and tonsil secretions on both sides.

2. The nasopharynx swab was put into the virus delivery medium, and the auxiliary tube cover broke the swab rod to make it completely placed in the tube.

3. Tighten the pipe cover, mark it, put it in a plastic bag and seal it.

4. Send the samples for examination in time.

Flocked swab definition

Flocked swabs meaning

Using spray dense planting nylon fiber technology; The volume of samples collected and released is 3 times higher than that of traditional swabs. Ensure the survival rate of cell samples, no residual fatty acids, and will not affect the test results.

Excellent sample collection / release ability, release rate > 90%.

Conventional flocked swab: the sample is intercepted by the gap in the fiber mass, that is, the sample is penetrated, diluted and intercepted in the fiber. The acquisition is slow and release is slower.

The sampling time of flocked swabs is 3-5 seconds, while the sampling time of cotton swab is 15-120 seconds or even longer, which causes the pressure of staff in the process of diagnosis.
