False Positive and False Negative in Covid-19 Tests
What does False Positive & Negative Actually Means in Covid-19 Tests?
False Positive – A positive result means that you have antibodies to COVID-19 in your blood, which indicates that you were infected with the virus in the past. It is possible to test positive even if you have never had COVID-19 symptoms. There may be a false positive result. Perhaps the test detected antibodies to a coronavirus closely related to the COVID-19 virus or the quality of the test may have been flawed.
False Negative – A negative result means that you do not have antibodies to COVID-19, so you probably have not been infected with the COVID-19 virus in the past. Since it takes time to develop the antibodies, the false negative test result can occur if the blood sample is taken too soon after the start of the infection. In some cases, the test may be flawed.
