We can all agree that this particular pandemic caught us off guard. That is the main reason why we still cannot live in real-time and understand the importance of detecting the symptoms beforehand.
Some countries are testing as many people as they can, while others choose to do it only to people with some symptoms.
In both cases, the general statement from the World Health Organization and WHO is that the best way to fight against this invisible enemy is by being proactive.
We can differentiate different reasons why each country should implement mass testing; however, some countries would break down with the high number of positive patients.

That is why they choose to help people with problematic symptoms because their health systems cannot handle a large number of positive patients at once.
Let us see the most commonly used tests for detecting this horrible pathogen.
The most popular and commonly used screening method for coronavirus is NAAT or Nucleic Acid Amplification Test. A practical solution will help you detect this particular virus, which is responsible for the pandemic that surrounds us.
The process requires using a specimen from the upper respiratory tract througha nasopharyngeal swab technique. It requires a sample from the throat behind the nose that features a combination of saliva and mucous for further efficiency.
Generally, it requires approximately up to four hours for detection, which is an important consideration when compared with other screenings used nowadays.
Everything happens in the specialized laboratory that tests specimen in real-time by conducting a reverse-transcription polymerase chain reaction assay. Remember that this particular method is particularly useful for detecting specific genetic marketsfrom this virus.

According to reputable labs, this specific screening method is highly reliable, especially when compared with others.
The technique is perfect, but it is not widely available, which makes it inconvenient, especially during the pandemic, in which everyone is trying to get it as much as it exists.
We have mentioned above NAAT is one of the fastest methods that require approximately up to four hours for the testing process. At the same time, patients will be able to get the results in a few days depending on the number of people tested simultaneously.
Remember that this particular screening type can easily detect the number of antibodies within the blood serum. During the immunity reaction, white blood cells produce proteins with an idea to fight against the foreign bodies that we know as antigens.
According to most researchers, this particular screening method will check the serum that includes specific antibodies known as antigens that are trying to fight the foreign bodies as part of the immune response.
Most researchers state that this particular test is an effective way to detect the current infection rate as well as the ability to determine the overall mortality rate afterward. It is also an efficient way to identify people that already developed particular antibodies to this virus.
In further studies, they can act as donors to help other people that are infected. Finally, this is the first step towards creating a vaccine that will help people from all across the globe. It is a game-changer, but generally, it is useful only if an individual develops antigens.
Some cases have stated that we lack immune response when coronavirus enters our system, which means that we require the proper number of antibodies that may help determine the current infection rate and help others as well.
Who Should Be Tested?
The standard perspective when it comes to priorities is that countries are choosing to test only people that have shown symptoms that are common with coronavirus. At the same time, people with mild symptoms would have to wait for their turn, because the testing kits are scarce.
According to the World Health Organization, if you are positive, the first thing you should do is determine the people you were in close contact in the last seven days. They also require screening, especially if they show common symptoms.
In most countries, the screening process takes place in specialized medical facilities, such as clinics and hospitals.
Have in mind that in some countries such as UAE, Canada, and Germany, they opened testing centers outside the hospital settings with an idea to increase the number of tested people.
For instance, South Korea is the leader in the number of tested residents, and they started authorizing roadside tests. That way, they think that they will lower the chances of getting sick or expanding the number of affected people in the future.
The overall process requires ten minutes. It uses the bottleneck-sampling process, which means that staff is wearing protecting suites and take samples from people with typical symptoms.
