All about the Nasal Swab

Nasal Swab:nasopharyngeal np swab.

The specimens collected from nucleic acid samples are mainly pharyngeal swabs, which are divided into “nasopharyngeal swabs” and “oropharyngeal swabs“.

Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth, and nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

How to do a nasopharyngeal swab?

Nasopharyngeal swab sampling method.

Hold a swab close to the nostril to enter, and slowly go deep along the bottom of the lower nasal tract.

Since the nasal tract is curved, do not use too much force to avoid trauma and bleeding.

When the top of the swab reaches the posterior wall of the nasopharyngeal cavity, rotate it gently for one week (stay for a moment in case of reflex cough), then slowly take out the swab and immerse the swab head into a tube containing 2 ~ 3ml virus preservation solution.

About Nasal swab sample collection.

How to take a swab sample?

Ask the patient to take off the mask and blow his nose with a paper towel to remove excess secretions from the nasal cavity. Remove the swab from the package.

Tilt the patient’s head back slightly to make the nasal passage easier to pass through. Ask the patient to close their eyes to reduce the mild discomfort of the operation.

Gently insert the swab over the bottom of the nasal canal along the nasal septum until the nasopharynx stops when resistance is felt.

Insert the cotton swab parallel to the upper jaw into the nostril.

If you feel resistance when passing, step back and try to reinsert it at another angle to bring it closer to the bottom of the nasal canal.

The depth of the swab should be equal to the distance from the nostril to the opening outside the ear.

CDC recommends placing the swab for a few seconds to absorb enough secretions, and then slowly removing it while rotating the swab.

Some organizations may also recommend rotating the cotton swab several times before taking it out.

After removal, ask the patient to put on the mask again.

Specimen processing

Open the virus transport medium and insert the swab into the collection tube.

Break the swab at the groove and discard the remaining part. Seal the labeled collection tube and place it in the biohazard garbage bag.

According to convention, you can return the sample to its original packaging for disposal.

Follow CDC instructions for direct treatment of swab specimens or place swabs in medium with or without refrigeration.

Quick covid test

Quick covid test |How does covid testing work?

Posted on by

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 much does it cost?

Please contact us for more details.

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.

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 swb

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.

We made a comparative experiment according to the effects of temperature and storage time on the preservation of virus.

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.

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.

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

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.
