New Delhi. Recently, two cases of corona related to Melbourne have now been put in the category of False Positive. It has been omitted from official statistics. RT-PCR test is the most efficient way to test corona ie SARS-CoV-2. If someone does not have corona infection, then there is every possibility that the report will come negative.

There are two types of tests to check for corona infection – RT-PCR and antigen test. Doctors across the world consider RT-PCR to be the best. RT-PCR stands for Real Time Reverse Transcription Polymerase Chain Reaction. In this test, a sample (swab) is taken from the nose or throat. After taking a swab from the patient’s nose or throat, it is sent to the lab for testing.
What is the reason for false positive report?
The main reason for this is laboratories error and off-target reaction. That is, the test is to cross-react with something that is not SARS-CoV-2. Clerical error in the lab. Wrong sample test. Apart from this, a person who has had COVID-19 and has recovered can also show a false positive report result.
How common is a false positive report?
For a false positive report, we have to see what percentage of such reports are coming. A study has shown that the rate of false positive is 0-16.7 percent.
