FDA (Food and Drug Administration) gives the latest tool- Antigen tests as the emergency use authorisation Trusted Source for the prevention of the Corona virus transmission. But it acts same to that of the strep or rapid flu tests.

It is designed in such a way so that it is able to identify the traces of tiny protein in the collected nose or throat swab sample which forms due to the COVID- 19 (Novel Corona virus). For this, your nasal cavity sample will be taken by using a swab and send to the laboratory for extensive review.

For performing antigen test, rapid test kit (developed by Quidel Corporation in San Diego) is provided to the patient, which will deliver the result in 15 minutes. Although at present only 1 antigen test is approved for a person, it will be evaluated by FDA and accordingly authorisation will be given to more of these tests later.

As per FDA the biggest advantage of this test is its incredible speed. It will incorporate in knowing the current situation of the area (especially person’s health- whether there is an exposure of virus or not). Accordingly the economy will be reopened and people will be allowed to set back to their work following all the safety norms.

In contrary to other diagnostic tests, it is much affordable and is bearable easily by the people across the country. However, for health experts still there are some downlines which must be considered for administering this test. Let’s read this blog and know about it in an explicit manner.

Other tests are more accurate than Antigen tests

At present only PCR (Polymerase Chain Reaction) tests are available as diagnostic test for detecting Corona virus. It is done so by collecting the swab sample of an individual’s nasal cavity. It has the ability to identify the genetic material of the virus and determine whether the person is infected with Novel Corona virus (COVID-19).

PCR tests offer accurate report due to its sensitivity for detecting the genetic material presence in the nasal cavity’s swab sample of the person. For detecting so, it consumes some time for the processing before final interpretation of the report in the laboratory.

On the other hand, antigen test is performed by collecting the swab sample of nasal cavity for identifying the antigens (tiny protein fragments) which generally produced due to the triggering in the immune response after one gets subjected to the virus. As per the medical expert, basically it hunts of the tissue parts of the virus to confirm the presence of the infection in the individual’s body.

However it is lightening fast in delivering the report within a few minutes yet with a space full of errors. Being faster than ever it is not as much sensitive as PCR tests. For them, it neglects certain aspects which limit its value very low.

As in most cases it offers false negatives if the report in antigen test comes positive there is high probability that you are actually infected with COVID- 19 or Novel Corona virus. FDA reveals that a number of active infections are avoided by the antigen tests to deliver the fast result which is why it often ends up with false negatives.

Also known as Quidel’s test, Antigen test can only deliver 85% accurate positive cases. But it is a serious matter of concern because there are about thousands of tiniest virus particles for available for detection. Only RNA tests can detect each one of them individually and perfectly.

Even FDA suggests that Covid-19 PCR Test in London is a must for the verification of false negatives of antigen tests. Even medical experts don’t want people roaming around freely in the streets considering that they are free from this infection when in reality they aren’t!

How antigen test must be used?

As per the top medical expert, it is concluded that PCR tests are specific and most sensitive exam for the accurate determination of the COVID-19-infected persons. On the basis of the diagnostic testing purpose for accurate detection and transmission prevention antigen tests proved to be inefficient and possess certain limitations as well.

In case the test report is needed for any purpose such as for travel, set back to work and commutation then PCR Covid-19 Test in London is the best option for detecting the trace of its genetic materials in the body. But if you need the result for checking whether you are free from this gnarly virus or not then you may go antigen test.

However, you should validate it with PCR test to check whether you need to stay in home-quarantine or not! As it is not accurate in delivering the report stating the health condition of the individual yet it can at least assist in managing this ongoing pandemic to some extent.

FDA authorised the Antigen tests as the emergency usage tool for combating against this new Coronavirus. Although the test performs much identical to that of the strep or rapid flu tests yet it is meticulously designed for detecting the tiny protein pieces of the virus rapidly. It is done so with the collected swab sample of nasal cavity of the person.

It is efficient it generating quick reports at affordable price but most of the time it comes with false negatives. That’s why it is recommended that this test report should be verified with a PCR (Polymerase Chain Reaction) test.

Even only with Fit to Fly certified PCR Covid-19 Test report you will be allowed to travel abroad for your business or work purposes. Contact a clinic offering this test, and schedule an appointment today to get tested and fly freely.
