The term RT-PCR stands for Reverse Transcription Polymerase Chain Reaction Test for the detection of nucleic acid from SARS-CoV-2 in respiratory tract specimens collected from individuals suspected of Covid-19 virus. It is performed using oral or nasal swabs taken from the person. The procedure of the RT-PCR test involves extraction of RNA’s genetic material. The best part of RT-PCR is that it is very reasonable to afford.
As per government information collected and verified, RT-PCR tests are accurate compared to any other covid tests.
Experts generally agree that RT-PCR is more accurate than rapid antigen test and antibody tests, which are better uses for confirmatory tools. However, sometimes test reports cannot be considered as completely perfect because of certain factors. Like, not properly administered and that gives false results.It properly analyzes the SARS-COV-2 virus that is why the accurate rate remains high.
Major reasons behind the high demand of the RT-PCR test is that there are no side -effects. Even though tests with no side effects, there remains a chance of false-positive or false-negative reports that confuse further treatments.
Yes, the RT-PCR test is safe for both kids and senior citizens.In fact, it is a simple process of genetic material. That’s why RT-PCR is the most widely used testing technique to detect the presence of Covid virus.
Now RT-PCR in India is the recommended method for covid testing. The medium of collection is Nasopharyngeal (Nasal) and Oropharyngeal (Oral) swab is collected by taking precautions.
If the person has symptoms of COVID-19 or have been exposed to people who have symptoms or have tested positive, you may get tested.
The RT-PCR test is to detect genetic material (RNA) that is specific to the virus. Whereas, the Rapid Antigen Test is to detect protein fragments specific to the coronavirus.
The samples that are collected for RT-PCR test are nasal swab, throat swab, saliva swab. In Rapid Antigen Testing samples are taken from nasal swabs. The result of RT-PCR may be available from 24hrs to 48 hrs whereas, result of the Rapid Antigen Test will be declared much faster within 15-30 minutes. Accuracy result of RT-PCR is more than the Rapid Antigen Test. Most of the doctors may advise for RT-PCR test after Rapid Antigen Test to confirm the result.
