DNA can tell you a lot about you.

DNA sample collection DNA is collected from an individual (or individuals) using sterile swabs while following appropriate collection techniques.

A DNA test can do this by looking at your DNA to determine the DNA “function” it exposes in your genetic code.

This is the “feature” that some tests can provide for health and life.

The reason for the method information.

Under the license of numerous DNA companies, some will sequence your DNA through your clients to help you understand your family tree, the migration patterns of your ancestors.

Proper DNA sample collection techniques are an essential skill for forensic scientists, crime scene investigators, and medical examiners. We can collect DNA samples from many different sources.

Products found at a criminal crime scene that may not actually involve a true crime may provide DNA evidence.

What is a DNA test and how is it done?

Use your doctor’s genetic sample to test you or be asked to spit in a test tube , or be asked to flocked swab in a tube in your mouth.

If you have frequent dry mouth, you need to do a cheek test. Another could be a lemon bite, the taste of a lemon, and then a bite of the lemon. When to get those drools back. Besides, you can also learn a little more but about DNA testing things!

DNA sample collection method

: generally choose routine: bloodstain, oral test, long sample;

Swab collection method:

  • Rinse your mouth with water to make sure there is no food residue in your mouth.
  • Open the DNA storage solution tube. Turn the cap down and the spout up.
  • Unwrap you and stick your fingers around the probe. It is important not to probe with a profiler of a profiler, as this can affect the profiler results.
  • Insert a medical DNA swab into the mouth and rub 30 times on the cheeks.
  • Take a cotton swab and dry the swab in the shade; use the same method to collect three DNA subs.

Exactly how to prevent DNA evidence contamination

When managing all organic evidence for DNA screening, it is imperative for investigators and laboratory staff to wear the correct personal safety equipment, use tidy instruments, and avoid interactions with various other objects to reduce the threat of compromise of any evidence.

Improper storage space, direct exposure to direct sunlight, or simply being comfortable can all cause damage to DNA. To avoid damage, keep accumulated evidence in a dry and cool place and send it to the laboratory immediately.

What is the source of DNA you can wipe?

You can easily wipe down many common DNA sources. These include blood, feces, urine, semen, saliva, hair, teeth, bones, and cells. DNA can also accumulate from selected surfaces and materials.

Where can DNA samples be obtained?

DNA samples can be extracted from drinking glasses, cigarette butts, food with bite marks, bite marks on the skin, etc. You can also wipe down frequently touched surfaces such as computer keyboards, doorknobs, steering wheels, glasses, and countertops.

Verifying shipping systems from several suppliers has come to be a common practice in research laboratories around the globe, not just to ensure sustainable supply, but likewise to compare item top quality and expense.

Dog DNA Tests

Dog DNA Tests_The owner is isolated and the pet needs swab test!

Posted on by

A few days ago, a patient in the USA, was diagnosed with a COVID-19 infection. Due to the quarantine, no one at home is taking care of the pet dog. So she turned the dog over to the US Animal Protection Service.

The site is responsible for monitoring animal welfare and controlling animal and plant infectious diseases, such as foot-and-mouth disease, bird flu and other animal diseases.

The staff suddenly wondered if the dog also carried the new coronavirus-19. Therefore, the staff took swabs (secretions and feces) samples from the dog’s mouth, nose and anus for the new coronavirus nucleic acid test.

The new test results were unexpected: the oral and nasal swabs of the new coronavirus-19 were weakly positive in the swab test, and the anal swab test was negative.

However, the symptoms of COVID-19, such as fever and cough, look very lively and healthy.

The transmission of COVID-19 to pets has been the focus of discussion in the scientific community.

Currently, the Society’s Animal Residence has only tested this dog. Not sure if other animals have the same problem.

Subsequently, staff stepped up protective measures for the animal shelter and disinfected its facilities, walls and floors. Out of an abundance of caution, staff also isolate the dogs and observe them closely.

The person in charge of the animal protection station said that the dogs will be re-examined after that.

Although the pet dog had no symptoms of Covid-19 infection, the discovery of suspicious evidence of Covid-19 infection for the first time really took the world by surprise.

The swab test for COVID-19 was weakly positive, with both false positives and positives.

If the dog’s new coronary pneumonia swab test is finally positive, there are two possibilities: one possibility is that the dog is also infected with new coronary pneumonia; the other possibility is that the dog brought the virus into the mouth or Nasal, i.e. mechanical carry.

A dog’s mouth, nose and ground compared to a human. Surfaces with closer contact and smell habits are more likely to inhale some pathogens, including COVID-19 that may be present in the environment.

It is worth noting that the current medical institutions pay more attention to the diagnosis and treatment of infected patients; the CDC pays more attention to the source of the new coronavirus-19 infection and adopts various prevention and control measures. Few institutions test animals that are closely related to people, such as pet dogs, domestic cats, livestock, and even domesticated birds.

Whether these closely related animals carry the new coronavirus disease as a vector of infection or transmission; or whether dogs can be infected with the new coronavirus is unclear.

Dogs themselves can also be infected with coronaviruses, but the common coronaviruses that dogs contract cannot infect humans;

why?

The cat is being made a swab test

The cat is being made a swab test

Generally speaking, a virus needs to enter an animal or human cell in order to infect, replicate, and cause disease.

First, the virus must recognize receptors on the surface of the cell it wants to invade.

For example, SARS-CoV-2 needs to bind to a receptor called angiotensin-converting enzyme 2 (ACE2) to infect humans and cause disease, which is the equivalent of a key to a lock.

The virus then binds to a receptor expressed by the cell, the virus integrates into the cell, and infects the cell.

The ultimate determinant is its genetic material and genes (the material basis is DNA).

Obviously, the DNA of animals and humans is different, and the proteins expressed on the cell membrane are also different. Sometimes it looks the same. As long as

several amino acids are related, the profile of the protein is different and the virus cannot bind to it.

However, this is not absolute, as the virus is constantly mutating and adapting to the environment.

If the new coronary pneumonia can be directly transmitted across species, it can indicate that this virus infection is a zoonotic disease, which is obviously very bad.

A warm reminder from Dr Lee:

We found weak nucleic acid positive for New Coronavirus disease in pet dogs.

This message tells us:

1. In addition to guarding against infection by infected persons, it is also necessary to avoid close contact with active animals, including pets living together for a long time;
2. If you accidentally touch these animals, you must wash your hands afterwards;
3. Wear a mask and do a good job of protection before touching animals as a last resort;
4. During the epidemic, we suggest taking good care of pets and do not take pets for a walk outdoors.

During an outbreak, everyone should be familiar with sampling swabs. When doing nucleic acid, touching the nose and throat is directly touching the sampling site of human organs, that is, directly touching our human organs. Therefore, the material of the sampling head will affect our comfort and is closely related to the subsequent detection.

On This Page

What is a Nylon flocked swab?

About sampling swab material.

What are the types of swab tests?

Nylon flock swab

Sampling swabs should be polyester, nylon and other non-cotton, non-calcium alginate swabs, and the handle should be non-wood. The breakpoint is located about 3cm from the top of the swab head, which is easy to break.

NASAL FLOCKED SWAB

NASAL FLOCKED SWAB

Moreover, the experimental analysis shows that the extraction efficiency of nylon flocked swabs is the highest. In contrast, the recovery efficiency of nylon flocking swabs is also higher than that of other material swabs.

Nylon fibre flocking technology. The front end is coated with vertically fixed nylon short fibers, so that the entire sampling area of ​​the sampling swab has no absorption holes, and the sampling sample will not be scattered in the fibers, which is conducive to faster and more efficient sampling!

Compared with traditional winding swabs, nylon flocking swabs collect and release 3 times the number of samples, do not damage cell samples, ensure the survival rate of cell samples, do not leave fatty acids, do not affect the test and detection results, not to mention Said to cause harm to the human body.

What materials cannot be used for sampling swabs?

As we all know, the materials of medical swabs have always attracted much attention. After all, medical swabs come into direct contact with the skin. People who touch the skin can first touch alcohol for disinfection, that’s fine, but what about those who have direct contact with organs? For example, the throat swab we are most familiar with during the epidemic.

The throat swab is in direct contact with the sampling site, and the material of the sampling head is closely related to subsequent testing. The sampling swab head should be made of nylon flocked swabs or rayon, and calcium alginate sponges or wooden stick swabs (including bamboo sticks) should not be used.

Cotton products should not be used for the swab head, because the cotton fiber has strong adsorption to protein and is not easy to clean into the subsequent storage solution; wooden.

What are the types of swab tests?

There are two different types of COVID tests – Swab tests and antibody tests.

1. Swab tests can show if you have an active coronavirus infection and should take steps to isolate or isolate yourself from others. There are currently two types of diagnostic tests – molecular (RT-PCR) tests that detect the genetic material of the virus, and antigenic tests that detect specific proteins on the surface of the virus. Samples are usually collected with a nasal or throat swab, or saliva spits into a test tube.

2. Antibody tests look for antibodies that the immune system produces in response to a threat, such as a specific virus. Antibodies can help fight infection. Antibodies can take days or weeks to develop after infection and may remain in the blood for several weeks after recovery.

Therefore, antibody tests should not be used to diagnose active coronavirus infection.

Right now, researchers don’t know whether the presence of antibodies means you’ll be immune to the coronavirus in the future. While there is a lot of uncertainty surrounding this new virus, the widespread availability of antibody testing and clinical follow-up over time also has the potential to provide the medical community with more information about whether and how long a person has recovered from the virus of people have a reduced risk of infection if they are re-exposed to the virus.

How to Swab For Covid Test

Since the outbreak of novel coronavirus pneumonia, we must have experienced nucleic acid testing. Covid swab test Nucleic acid detection plays a very important role in the process of infection diagnosis of COVID-19. It can not only find asymptomatic patients in the incubation period as much as possible but also greatly reduce the risk of infection.

Nucleic acid detection is so important. Next, Dr Li will take you to have an in-depth understanding of the relevant principles of nucleic acid detection, the difference between mixed collection and single collection of nucleic acid detection, and the matters needing attention in nucleic acid detection, to help you better protect yourself while popularizing knowledge.

To understand nucleic acid detection, we must understand the detection principle. Let’s take a look at its detection principle first.

The doctor is testing the patient's nasopharynx swab

The doctor is testing the patient’s nasopharynx swab

What is the principle of nucleic acid detection?

Nucleic acid, the genetic factor of the virus, is a macromolecular chain composed of four nucleotides. Different molecules represent different nucleotides and form a long chain. Nucleic acid detection is through the detection of nucleic acid in the chain, and this segment of nucleic acid is COVID-19 specific, other viruses do not.

Pcr test nasal swab and an antigen test difference for covid 19

Pcr test nasal swab and an antigen test difference for covid 19

The substance detected by the nucleic acid is the nucleic acid of the virus. At present, the detection technology is mainly through PCR (polymerase chain reaction) technology to detect the nucleic acid of the virus. During the detection, the nucleic acid chain of COVID-19 was used as the detection target, and the target gene sequence was amplified by PCR Test, which was combined with a fluorescent labelled probe added in the test reagent to produce a fluorescence signal.

The three forms of nucleic acid detection have their advantages.

Nasal swab test

This test method is to insert the test swab vertically into the nostril. And gently rotate the swab, stay in the nasal cavity for about 15 seconds, to test.

Compared with throat swabs, nasal swab testing is more accurate for inexperienced testing personnel. And the risk of exposure is lower. However, it is not suitable for some patients with nasal allergies, high blood pressure and people who take anticoagulation and antiplatelet for a long time.

Throat swab test

At present, the most widely used detection method is also a form that is often used by everyone. During the sampling process, the patient opened his mouth and made an “ah” sound, and the testing personnel used a sterilized cotton swab to gently and quickly wipe the pharyngeal lateral wall and posterior pharyngeal wall of the subject many times.

COVID-19 Testing:PCR swab test,antibody test, and antigen test difference

COVID-19 Testing: Throat swab test

Throat swab testing: Often used in the testing process because it is more convenient and fast to collect, and it is more acceptable to the public, but the risk of exposure is also greater.

Anal swab test

This test method is a method of inserting a test swab into the anus and taking a sample at the fold of the anus or taking a sample at 2 to 3 cm for a new coronavirus test.

Many patients reject anal swab testing, but anal swabs can improve the accuracy of testing for new coronavirus infections to a certain extent. Some patients indeed have negative throat swabs, but positive ones are detected by anal swabs. In some patients, the anal swab test was still positive after the other two tests turned negative.

Anal swab

Anal swab

Why do multiple nucleic acid tests need to be performed?

Multiple nucleic acid tests are necessary for epidemic prevention and control.
A negative nucleic acid test does not mean that the tested person is not at risk of infection. Any detection method has the possibility of errors, especially in high-risk areas. To ensure the accuracy of the inspection results and better prevent and control the spread of the epidemic, multiple rounds of inspections must be carried out. There are also the following reasons for taking multiple rounds of detection:

After virus infection, the human body has a certain value-added period. When testing, if the virus in the body does not reach a certain concentration, we may not detect the virus.

When the specimen was collected, due to the different sampling methods, no virus cells were collected. False-negative specimens can also lead to inaccurate collection results.

Errors in the transportation process and storage of samples for inspection will also affect the results of nucleic acid testing.

Therefore, for risk areas and special populations, multiple rounds of nucleic acid testing must be carried out to more accurately and effectively detect the virus source, so as to better and more accurately prevent and control and identify infected people, and cut off the source of the virus. No matter what kind of inspection process, attention must be paid.

How accurate are saliva swab DNA tests?

Posted on by

Is the DNA test of the saliva swab accurate?

Many people doubt the accuracy of the saliva swab test.

However, you can rest assured, because the accuracy of oral saliva swab testing is as accurate as other DNA testing methods.

Moreover, this is not the same as a finger puncture or a blood test, it is not painful at all.

In recent years, DNA testing has become more and more popular.

Whether you want to confirm your parental relationship, understand where your genes come from or want to optimize your exercise.

We are currently working on direct-to-consumer DNA testing of saliva swabs.

You have decided to use DNA testing to better understand your body and optimize your training.

However, before you take the first step and buy a set of home DNA testing kits, you should have some concerns.

Although most of the feedback and research has been confirmed to be positive, we are here to learn more about this and help you make an informed decision.

How much saliva is needed for a DNA test?

Saliva Sample Collection Kit :Disposable saliva DNA RNA sampling tube

Saliva Sample Collection Kit: Disposable saliva DNA RNA sampling tube

2ml-4ml.

The saliva collection components are easy to use, and each set has detailed instructions.

You can provide samples for different health conditions, including common medications used during pregnancy, colds or flu (including medications for acid reflux or heartburn).

But if you want to use drugs to reduce the white blood cell count, such as chemotherapy, you’d better wait two weeks or wait until the white blood cell count returns to normal.

After mixing with DNA stabilizing buffer, the temperature range of your saliva sample (-4oF to 122oF) is stable.

Please send the collected samples to the laboratory as soon as possible.

Is the DNA test at home accurate?

Yes, DNA testing at home is very accurate.

You will only encounter errors when the genetic sample is damaged (for example, you have eaten before the sample is collected) or the laboratory quality is poor.

Therefore, it is necessary to choose a well-known DNA testing supplier for testing.

An accurate genetic test report can know in advance whether the body is in danger of disease.

By improving the living environment and behaviour habits, avoiding or delaying the occurrence of the disease, or determining whether there is a specific drug in the case of malignant disease.

Target, so as to more accurately select the treatment method.

The results in each report are derived from at least three peer-reviewed research papers.

It just repeats the genes that have an impact on health, health and nutrition.

This means that you can change the way of real-life based on the genetic variants you carry.

Through strict internal and external procedures, we have passed ISO27001 certification to identify risks, evaluate all control systems, improve our reliability and security, and comply with international data security standards, so as to ensure that our customers and business partners can trust us.

What can you do to ensure that your DNA test results are accurate?

In order to ensure that your DNA test results are accurate, you need to follow the instructions at the back of the box.

Before starting, please read the instructions carefully:

Before wiping dry, make sure you have nothing to eat or drink.

-The best time to take the exam is to brush your teeth in the morning and the first thing before drinking the first cup of tea.
Before taking the test, it is best to open the sealed mouth swab to ensure that it will not be affected.

After removing the cotton swab, open your mouth and use a pointed tip (cotton swab, slightly larger) to gently wipe your cheeks.

Try not to scrub vigorously, because the important part of the sample is saliva.

Be sure not to put paper towels in the plastic container provided.

Take care to break the pole where it is needed.

Fill out the attachments, sign and seal the enclosed envelope, and then send it to the laboratory for inspection.

Bear with patience and watch your test. This process will start with the receipt of samples in the laboratory and will take 10-14 days.

Is the accuracy of mouth swab detection relative to other DNA collection methods?

Because the saliva swab is noninvasive, many people question its accuracy.

However, you can rest assured that the accuracy of oral swab detection is as accurate as other DNA detection methods. And, unlike finger punctures or blood tests, it doesn’t hurt at all.

Whether you are building a cabinet in IKEA, pressing a map or doing DNA testing, you can get accurate results as long as you follow the instructions.

Remember, DNA testing is wrong only if your test results are wrong or you don’t follow the instructions.

Cost is an important factor in performing such tests, so it must be studied.

Often, you don’t just pay for the test suite. You also have to pay a test fee to analyze your results. If the test you selected does not belong to the laboratory, please choose a supplier with a good reputation and excellent laboratory.

Every laboratory we use will conduct regular spot checks to ensure that your samples have been tested correctly and your results are 100%.
