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.

Detection of viral nucleic acid sequence based on reverse transcription polymerase chain reaction (RT-PCR) is the main means for large-scale screening of new coronary pneumonia.

Generally, nucleic acid detection technology has the characteristics of early diagnosis, high sensitivity and specificity.

And it has the advantages of sample collection and preservation, personnel operation, nucleic acid extraction.

The performance of the kit is the cause of false negative or false positive test results.

Flocked swabs are the main samples for PCR. In the selection of raw materials, flocked glue plays a key role in the collection and release efficiency of swabs. Whether to use high-quality aqueous flocking glue is the main factor affecting the water absorption and hydrophilicity of fluff. The experiment is to compare the sample collection effects of swabs flocked with different glues.

What is a flocked tip swab？

The top of the flocking swab is a nylon fiber structure.

Nylon fibers are deposited on the surface of plastic rod in a certain direction by electrostatic field to form brush layer.

The layers are completely parallel and perpendicular to the inner rod surface.

Flocked tip swab brush head can effectively collect samples.

Flocked tip swab factory Product advantages.

The flocked swab can completely capture the cell sample through the directional friction effect of the brush fiber layer.

The capillary movement between the nylon fibers at the front end of the flocking swab can form a strong hydraulic pressure for absorbing liquid or cell line samples.

Cell samples can also be evenly and neatly concentrated on the near surface of brush fibers, so more than 95% of the samples can be released finally.

Virus preservation solution is a solution for virus sampling, preservation and detection. What kinds of virus preservation solution are added to the virus sampling tube?

virus transport medium

virus transport medium

There are two types of virus preservation transport Media: inactivated and non inactivated.

The following briefly introduces several principles for the selection of virus preservation solution.

Non inactivated virus transport medium:

The non inactivated type does not contain lysate.

On the basis of Hank’s, BSA (bovine serum albumin) amino acids, vitamins and other nutrients required by the virus are added, which can maintain the activity of the virus in a wide temperature range and maintain the originality of the sample to the greatest extent.

For nucleic acid extraction and detection of the virus, virus culture and separation.

Characteristics of non inactivated preservation solution:

COVID-19 Sample Collection and Transport kits Use process

COVID-19 Sample Collection and Transport kits Use process

1. It can maintain virus activity for detection or virus isolation;

2. It has no inhibitory effect on subsequent nucleic acid amplification;

3. stored in cold storage(at 2 ℃ ~ 8 ℃ ).

Inactivation virus transport medium:

Inactivation preservation solution can inactivate the virus in the sample by fully mixing the collected sample with virus lysate and virus nucleic acid preservation solution, and effectively ensure the integrity of virus nucleic acid in the sample.

About the preserved viral RNA samples: used in gene detection, enzyme-linked immunosorbent assay (ELISA), PCR detection and so on.

Inactivation preservation solution includes guanidine salt containing and guanidine salt free.

1. Guanidine salt

(1) Instantly cleaved and inactivated to reduce the risk of sampling;

(2) Stored stably at room temperature for 2 weeks;

Virus DNA / RNA sample preservation solution (inactivated or non)

I believe that my friends must be very curious when they first came into contact with this term. Virus DNA / RNA sample preservation solution, also known as cell preservation solution, virus transport medium or disposable virus sampling tube.

What is a virus transport medium?

First, the virus preservation solution is a liquid that immerses the sampling swab virus sample in the sampling tube and protects the detected substance (DND or RNA) of the virus.

It is mainly used for the collection, preservation and transportation of common virus samples such as New Coronavirus, hfmv, influenza virus and so on.

Researchers can use it to collect throat swabs, nasal swabs, or tissue samples from specific sites.

The samples are stored in a disposable virus sampling tube, which can be used for subsequent clinical experiments such as nucleic acid extraction or purification.

We divide virus transport media into two types, one is non inactivated and the other is inactivated.

The non inactivated type can protect virus protein and nucleic acid, preserve virus activity and facilitate culture and detection.

The inactivated type makes the virus no longer have physiological activity, lose infection and disease, and have fecundity, which can inactivate the virus.

Eliminate secondary infection and protect the safety of transportation and testing personnel.

Because the virus is a parasite, it cannot survive in vitro after sampling. If it cannot be detected in time, it needs to be stored in virus preservation solution.

In order to protect the security of virus detection environment and detection personnel, our virus inactivation preservation solution comes in handy.

Some friends may wonder if the inactivated type will inactivate the virus? How can we check it?

Don’t worry, the purpose of using inactivated preservation solution is to lyse nucleic acid.

Release nucleic acid and then detect nucleic acid through subsequent real-time fluorescent RT-PCR to judge whether the sample contains virus characteristic nucleic acid, that is, whether it is infected with virus.

The virus has a single structure and contains only one nucleic acid and protein. Therefore, the virus is detected when the characteristic nucleic acid is detected.

Then some friends will ask, since the detection is so simple, why do you need virus preservation solution? What role does it play?

Usually, after virus sampling, not all samples can be transported and stored at the sample collection place.

Therefore, we need to transport and retain the collected virus swab, otherwise the virus nucleic acid will degrade quickly and the nucleic acid cannot be detected.

Therefore, we need to add preservation solution to the sampling tube to prevent the virus nucleic acid from being degraded so quickly.

Cell Medical’s virus preservation solution allows viral DNA/RNA to be stored and transported at room temperature for 1 week without degradation.

After extraction using most commercial kits, the obtained DNA/RNA is of high quality and high yield, and can be used for various gene testing and analysis experiments, such as PCR and qPCR, while saving transportation costs.

Cell Medical’s inactivated virus storage fluid uses a small volume storage fluid compared to the large volume storage fluid of a traditional virus sampling tube, which avoids excessive dilution of the collected samples and increases detection sensitivity.

And our inactivated virus storage solution is so easy to use that you can take samples at home.

Moreover, our inactivated virus preservation solution is simple and convenient to operate. You can take samples at home.

Well, if you have anything you don’t understand or want to consult, please leave us a message.

We will have a professional doctor and my little brother will let you answer.

COVID-19 Testing: Method of collecting virus swab samples

COVID-19 Testing: Method of collecting virus swab samples

Posted on by

COVID-19 Testing: virus swab

According to New Coronavirus’s pneumonia diagnosis and treatment plan (trial version fourth), to diagnose suspected cases of New Coronavirus pneumonia, we need one of the following etiological evidence:

1. Respiratory tract specimens or blood samples were detected by real-time fluorescence RT-PCR for New Coronavirus nucleic acid positive.

2. Novel coronavirus is highly homologous to respiratory tract specimens or blood samples.

Therefore, novel coronavirus pneumonia is an indispensable part of the specimen collection. So, where to collect specimens? How to collect specimens? How can medical staff protect themselves during collection? What should I do after collection?

How to obtain a virus swab specimen?

We all know that the collection method of virus swab specimen is basically to use the swab to sample the infected place or part of the virus, and then put it into the virus sampling tube containing preservation solution without touching other places, so as to conduct virus detection later.

Specimen type:

1. Upper respiratory tract specimens: including pharyngeal swab, nasal swab, nasopharyngeal extract, etc.

2. Lower respiratory tract specimens: including deep expectoration fluid, respiratory tract extract, bronchial lavage fluid, alveolar lavage fluid and lung tissue biopsy specimens.

3. Blood samples: try to collect anticoagulants in the acute stage within 7 days after onset. The collection volume is 5 ml, preferably fasting blood.

4. Serum samples: try to collect double serum in acute stage and recovery stage.

5. Conjunctival specimens: conjunctival swab specimens shall be collected for cases with ocular infection symptoms.

6. Stool samples: Patients with diarrhea symptoms need to collect stool samples.

COVID-19 Testing: Common virus swab sampling methods

Methods of throat swab collection

Inform the patient of the purpose of examination, collection method and collection time. It is best to collect specimens before using antibiotics.

Objective: To study the clinical effect of the method

Secretions were collected from pharynx or tonsil for bacterial culture or virus isolation to assist in clinical diagnosis and treatment.

Prepare sampling supplies:

Disposable sampling swab, virus sampling tube, tongue depressor and biological bag

Operation method:

(1) Ask the patient to sit down, tilt his head back, open his mouth and make a “ah ~” sound

(2) The sampling personnel shall fix the patient’s tongue with a tongue depressor, and use a disposable pharyngeal swab to pass through the root of the tongue to the posterior pharyngeal wall, tonsil recess and lateral wall;

(3) Repeatedly wipe 3-5 times to collect mucous membrane cells or sputum

(4) . gently remove the swab to avoid touching the tongue, the suspension, the oral mucosa and saliva

(5) Put the swab into the virus sampling tube gently and vertically. The sampling personnel shall disconnect the tail of the flocking swab and leave the tail of the swab completely in the tube.Be careful that the swab does not touch the wall of the tube.

(6) . tighten the cap, mark it, and seal it in the biosafety bag.

(7) The sampling personnel shall send the samples to the laboratory for testing in time. If the sampling personnel cannot send the samples for inspection in time, they shall store them at low temperature

Methods: nasal swabs were collected

Nasopharyngeal swab_COVID-19 Testing: Method of collecting virus swab samples

Nasopharyngeal swab_COVID-19 Testing: Method of collecting virus swab samples

(1) Ask the patient to sit down with his head slightly back and remove the secretion from the front nostril first;

(2)measure the distance from nostril to ear base with swab and mark with finger

(3)gently insert the swab into the nostril until it is marked or stopped when there is obstruction. Let the swab stay in the nose for 15-30 seconds, and then rotate it gently three times.

(4) slowly pull out the nasal swab and quickly put it into the virus sampling tube. Then break the swab, leave its tail and place it completely in the tube.

(5) tighten the cap, mark it, and seal it in the biosafety bag.

(6) If we need to collect from both nostrils, we should use a swab.

(7) It should be sent to the laboratory for testing in time. If it can not be sent for inspection in time, it should be stored at low temperature.

Generally speaking, COVID-19 testing: the main methods of collecting virus swabs are nasopharyngeal sampling and oropharyngeal sampling.

 

Is COVID-19 pneumonia more infectious than SARS?

The effectiveness of infectious disease transmission depends on its basic regeneration index. Novel coronavirus pneumonia is more infectious than SARS at present, with a basic regeneration index of SARS higher than that of SARS.

The novel coronavirus pneumonia is a new disease, and the population is generally immune. Everyone is susceptible and susceptible to infection. The incubation period of COVID-19 also has the ability to transmit, and it has longer infection time. The novel coronavirus pneumonia novel coronavirus pneumonia is also typical of the clinical symptoms, and asymptomatic infections are also contagious, so the infection of new crown pneumonia is higher than SARS.
