- A person with a viral infection produces antibodies (IgM/IgG) against the virus in their body.
- This Rapid test will tests whether a person has this antibody protein in his blood or not.
- This antibody protein is seen in the blood, with the result of the test.
- But it takes a few days to produce or become an antibody protein.
- Therefore, the test results are effective only after 7 days after the virus has been infected.
- If the result of the test is positive, the person may have had a virus infection in the past or present. But by the time this antibody protein is visible in the blood, the virus may have been removed from the person (with no apparent outbreaks in the nasal cavity for 14 to 21 days after the virus is infected).
- The results of the test do not say that there is no COVID 19 virus infection, since antibodies may not be abundant even during the first 7 days of the virus infection.
