A false positive Covid-19 test result can happen, but it’s rare, says Brian Labus, Ph.D., M.P.H., assistant professor at the University of Nevada Las Vegas School of Public Health.
Test errors can be false positives (the test is positive, but the virus is not present) or false negatives, (the test is negative, but the virus is present). [179] In a study of over 900,000 rapid antigen tests, false positives were found to occur at a rate of 0.05% or 1 in 2000.
Retroviral diseases (HIV, HTLV-1, and HTLV-II) often include mutations from guanine to adenine in their genome. Mutations such as these are what allow PCR tests to detect the diseases but Taq polymerase’s relatively low fidelity rate makes the same G-to-A mutation occur and possibly yield a false positive test result. [26]
The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate.
