Quick covid test |How does covid testing work?

Posted on 2021年11月10日2021年11月10日 by Dr. Lee

A new covid test at home has been authorized by the U.S. Food and Drug Administration (FDA) for emergency use (EUA).

Here’s what you need to know about testing at home.

How can I get quick covid test?

Cell medical’s covid test at home now has a prescription, which means Americans can get one from their health care provider.

If doctors suspect that their patient is infected with covid – 19 within the first six days of symptom onset, they can prescribe a rapid test.

How does testing work?

Rapid Antigen Test is a lateral flow test, a portable covid test that usually returns results faster than the widely used laboratory based PCR test.

It works by detecting nasal swab samples and provides positive or negative results within 10 minutes. The results appear on test strips exposed to nasal swab samples.

The FDA said flocked swab can be collected from people aged 8 and over, but if the tested children are less than 14 years old, it should be collected by adults.

How accurate is the test?

Cell medical claimed that the time when the positive results of the test matched the PCR test was 84.8%, and the negative results matched the PCR test were 99.1%.

FDA said that the negative test results of covid test do not necessarily exclude the possibility of covid – 19 infection.

“and should not be used as the only basis for treatment or patient management decisions, including infection control decisions.

“People who are negative and continue to experience COVID 19, have a fever, cough and / or shortness of breath, may still have SARS – CoV – 2 infection. Follow up care should be sought from doctors or medical staff. ”

Not all side flow tests require the use of prescriptions. On December 15, the FDA issued the EUA for the first outside counter flow covid test at home.

The covid – 19 family test also uses nasal swab samples to detect covid infection and works with people aged 2 years and older.

The FDA said that in the population with covid symptoms, the ellume test correctly identified 96% of positive samples and 100% of negative samples. In the population without symptoms, it collected 91% of positive samples and 96% of negative samples.

Similarly, the FDA said that the negative results of the test do not necessarily exclude the possibility of covid infection.

Broader prospects

According to CDC data, as of Monday, the United States had reported 47.5million cases of covid and 778,316 deaths.

The data also showed that 432 million people were vaccinated on Monday.

The covid test uses self collected swab samples.

But adults should take samples from children under the age of 14 and over the age of 8.

1. Sampling is more comfortable and convenient.

Our company uses the existing technology “spraying technology” to vertically attach millions of nylon flocked micro fibers to the head of medical grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of soft brush. Using this soft brush in the sampling process makes the user feel no foreign matter. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

For example, nasal swab, its upper end of the rod is thinner and softer, and its breaking point is longer.

Sterile Flocked Nylon Swab with 80mm Breakpoint.

2. Flocking swab samples release more.

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample remains on the surface to make elution easier. In the traditional cotton swab, most of the samples collected are still captured in the fiber matrix of the head, which is not easy to release or the release amount is small. Flocked swabs have been shown to release up to 95% of the sample, compared with 25% for standard fiber pointed swabs. If the sample size is particularly small, the use of flocking swabs is particularly important.

3. Flocking swab has biocompatibility and is an ideal choice for PCR.

In order to limit the damage to the sample and improve the accuracy of detection, disposable sampling swab is made of better quality nylon flocking swab.

This makes flocking swabs an ideal choice for PCR Swab Test. Therefore, for scientists using PCR technology, the new flocking swab is PCR compatible and does not contain RNase and DNase.

How are flocked swabs used for specimen collection swab?

Our flocked swabs feature perpendicular nylon fibers that optimize specimencollection and elution into transport media. The swabs also feature a moldedbreakpoint that allows you to safely and easily break off the swabstick, and severalbreakpoint options are available for different tubes.

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.

What are the advantages of flocking as a sampling swab?

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.

Advantages of flocked swab

Flocked Tip Swab,Cell medical (Dongguan) Co. ,Ltd.

·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.

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

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.

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.
