Covid-19, the deadly disease, not only crippled the economy but took away lives. The excessive destruction of human lives pushed people into fear. This led them to undergo rapid testing to make sure they were free from the virus.
During this uncertainty period, the need for a reliable testing method increased. And PCR testing came into existence.
What is PCR?
The covid-19 PCR (Polymerase chain reaction) tests were used to find out early symptoms in the body before even the individual fell ill. This means the viral RNA is screened before the formation of antibodies. Later, DNA polymerase is added to the samples.
This substance makes copies of the viral RNA in the body. During this process, these substances attach themselves to the genetic codes of the virus. And this indicates the presence of pathogens in the body.
With a lot of refinements in the process, PCR testing is becoming a trusted source.
If you suspect you or a loved one to be infected, you can take a PCR Test at home or get in touch with a covid-19 PCR testing service in the UAE.
How does it work?
The respiratory sample collection is done using a swab. This swab is sealed in a tube and sent to the testing center. In the laboratory, a process called extraction takes place. Later, special chemicals and a PCR machine are used to determine the presence of the virus.
Variations
The PCR tests use a variation known as the RT-PCR test. RT stands for Reverse Transcription. In this method, the RNA is reversed to DNA for accurate results. However, many people refer to both testing methods as ‘PCR’.
Why should you test?
In difficult times like this, being on the safer side helps you and your loved ones. If you identify any symptoms, immediately opt for a PCR test. By far, the PCR tests have been known to be accurate.
- Detects specific pathogens that are hard to identify in normal tests
- Rapid diagnosis of pathogens
- Quicker and more accurate
