Test to detect coronavirus structure: How it works

Until now, there are no vaccines or medications against the new coronavirus structure(COVID-19).

According to scientists, it can take up to 18 to 24 months before an appropriate vaccine can be developed;

  1. To check its side effects at all stages of the test
  2. Approve by health authorities
  3. Produce them in large quantities
  4. To distribute all around the world

Additionally, people will also have to undergo vaccinations.

Therefore, in the coming months, reliable testing is the most sensible measure to at least slow down the spread of the virus.

With the help of rapid tests, infected people, and possible infection, “hot spots” can be identified.

It is the only way to quarantine infected people, either in a medical facility or, in milder cases, at home.

However, even in developed countries like Italy and China, medical facilities and laboratories quickly reach their capacity limits during an acute wave of infection.

For this reason, limited rapid tests carried to suspicious cases; a general test for each person is neither possible nor useful.

Who needs to test against the coronavirus?

Based on current assessments, merely staying in a risk zone is not enough to warrant testing.

Not everyone with a cough or cold gets COVID-19 infected right away.

However, anyone who shows signs of pneumonia related to an “uncertain source” virus, with obvious symptoms such as;

  • Cough
  • Fever
  • Difficulty breathing
  • Who has also had contact with an infected person
  • Who remained in a particularly risky region affected is a justified suspicious case.

Ultimately, it is up to the physician’s discretion whether or not to perform a coronavirus structure test.

How is the test conduct?

In many cases, the test involves taking a sample from the patient’s throat or nose with a swab.

Several research institutes recommend that, in case of justified suspicion, samples from the upper and lower airways are essential. 

What about the samples?

The samples analyzed for the presence of coronavirus structure in diagnostic laboratories.

The procedure is based on the so-called Polymerase Chain Reaction (PCR).

These tests last about five hours and have become standard laboratory procedures.

Using these tests, we can detect inherited diseases or determine paternity.

In PCR, a specially selected piece of DNA is copy and multiplied in a thermocycler to search for specific parts of DNA, for example, a coronavirus.

The method then shows how many pathogens are present in the body.

In viral infections, this refers to a “viral load.

How coronavirus affected people informed?

The actual test lasts about five hours, plus the transport time to the test laboratory.


Results are usually available after a day or two before the doctor can inform the relevant patients.

If the test results yield positive, the patient and the corresponding health authority are immediately informed.

If necessary, this follows by a hospital admission with specially designed isolation rooms and protective measures.

In the event of a slight progression of the disease, patients may also remain in isolation at home.

Hence, provided that it ensures that they cannot infect third parties.

Is the evidence conclusive?

Hence, even a negative test does not completely exclude a possible coronavirus infection.

This can happen due to samples were;

  • Taken or transported incorrectly
  • Taken at the wrong time

This is another reason why allegedly infected patients get examined multiple times.

Are there any more comfortable and faster testing options?

Highly specialized laboratory equipment and highly skilled technicians required for this polymerase chain reaction diagnosis.

Even in China, the capacity of the laboratories quickly reached its limit due to a large number of cases.

In Europe and the United States, there is also this problem in the delivery of evidence.

So, since the tragic Ebola and Zika crises, researchers want to develop a portable version of these molecular diagnostic devices.

The main idea was to test people in less-equipped, or even decentralized, clinics in their home country or even in the home.

Research is ongoing around the world, and the first promising exercises for a simplified, rapid test, similar to a blood sugar test, are now available.

Nevertheless, the quick test presented by the Chinese National Health Commission will be able to detect immunoglobulins.

It is the antibodies that the human body produces first in the event of a new infection like coronavirus.



  1. For me these tests need to carried in other countries too. You have given a good points that I really love about. Thanks for this article. I’m following you now.
