When
it comes to approaching which test to take further for yourself there are
usually two types of test PCR and rapid Covid-19 test.
PCR tests are also known as polymerase chain reactions. It is a type of test
used to detect viruses in an individual.
How
Does the PCR Test Work?
The
PCR test takes the sample of ribonucleic acid and helps with the identification
of the virus present in the DNA of the individual. With the help of RNA, even
the smallest traces of the virus can be traced. It is detected as a useful
parameter to detect the SARS Coronavirus. The best part about the PCR test is
that it does not alter your DNA and apart from getting results, your DNA cannot
be used for any other purpose.
Benefits of PCR Test
Getting
a PCR test is the most effective way of detecting COVID-19, the perfect
solution when you require a quick PCR test for travel,
but it is not always possible to get an accurate result. PCR tests are done by
medical professionals that don’t provide instant results which means that it
will take time for you to know whether you are positive or negative.
“PCR
tests are more reliable and accurate due to testing the specific genetic
material of the virus, eliminating the interference from other viruses,” said
Heather Seiko, a Laboratory Services manager for OSF HealthCare.
How
Does the Rapid COVID Test Work?
The
rapid COVID test, also known as the antigen test, is the process of detecting
the COVID virus by identifying the protein found in the outer zone of the
virus. It works with the same nasal swab technique but delivers faster results
as compared to the PCR test.
The
method of determining the presence of virus in the sample is that in an antigen
test the liquid molecules of the virus get attached to the swab and help in
detecting the virus. If a line appears then the result is positive and if not
then the result is negative.
Benefits
of Antigen Test (Rapid COVID Test)
●
Instant Results within 15 minutes
●
The antigen test comes in handy and the person
can do it by themselves.
●
It helps in the further spread of the virus by
moving to places to get yourself checked.
Drawbacks
of Antigen Test
PCR
test generates more accurate results in comparison with the rapid antigen test.
As in PCR test virus molecules are recognized while in Antigen test only small
amounts of virus are recognized and are more likely to generate false results
sometimes. It is very difficult to test a person with an antigen test who is
asymptomatic.
Which
One to Choose: PCR vs Rapid COVID Test?
Getting
yourself tested can be a task. While you might have gathered the courage to get
yourself tested, choosing which test to do can be brainstorming. Whenever you
are visiting a medical professional you may not be able to choose which test to
go for.
The
PCR test is helpful in scenarios where there is a low risk of getting a virus
but the patient wants to be assured that he doesn't have one. The PCR test
gives more accurate results as compared to the Antigen test.
An
antigen test should be chosen if there are high chances for patients to have
conceived the virus. As they deliver faster results the treatment can go over
smoothly.
Conclusion
Getting
yourself tested is an essential part of cutting the spread of the virus and
ensuring a safe environment amongst your surroundings.
Always
choose reliable centers such as Covid Travel Vancouver for
this type of test.
