Of Those That Tested Positive During The Rapid Antigen Test, Researchers Confirmed That 462 Were False Positives.
If you have any doubt about your rapid antigen test result, it is recommended to discuss your results with a healthcare professional to determine next steps which may involve a confirmatory pcr. A test like a rapid covid test with a false positive rate of essentially zero has a specificity of 100 percent. Rapid tests are about 30% to 40% less sensitive than pcr tests, and they are more accurate in people with symptoms than without symptoms.

This represents 42 per cent of the positive test results in the study. The researchers explain that the false positives may have been from faulty issues. In total, 462 rapid test results, or 0.05 per cent of the 900,000 results, resulted in false positives.
Covid Rapid Antigen Tests Can Return False Negatives, But Experts Say They're Accurate When It Counts The Most.
The investigators were able to determine the rate of false positive. That said, if your rapid test gives a positive result, you should assume you probably have covid and isolate until you follow up with another type of test, like pcr. Less than one percent (1,322 tests) came back positive.
Rapid Coronavirus Antigen Tests May Give False Positives, Fda Warns The Agency Suggests Performing A Confirmatory Test Within 48 Hours Of A Positive Result
It's much higher — nearly 100 percent — when they're tested before that, though. Even a test with a very high 99% specificity (1% chance of false positives), when used to screen asymptomatic populations with a low background rate of actual infection, will yield high levels of false positives. However, a positive result is more likely to.
