Rapid antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are effective tools for the diagnosis of acute infection, particularly when used serially. The percentage of rapid antigen tests with false positive results is reported to be less than 1%.
Before you use a COVID-19 antigen test: COVID-19 antigen tests may not detect the SARS-CoV-2 virus early in an infection, meaning testing soon after you were exposed to someone with COVID-19 could lead to a false-negative result, especially if you don't have symptoms. This is the reason why repeat testing is important.
Xie et al. 1 similarly considered 167 infected patients of whom, five (3%) tested negative by RT-PCR at initial presentation. Fang et al. 3 found that RT-PCR was only able to identify 36/51 (71%) of SARS-CoV-2 infected patients when using swabs taken 0–6 days after symptom onset.
A negative COVID-19 test means the test did not detect the virus, but this doesn't rule out that you could have an infection. If you used an antigen test, follow FDA recommendations for repeat testing. If you have symptoms: You may have COVID-19 but tested before the virus was detectable.
For existing COVID-19 tests in the U.S., there have been reports of false negative tests in some patients. False negative tests can occur if a specimen was not properly obtained or if a patient was tested too early or too late in their infection.
The false positive rate (single gene low level positive) in this period was 0.5% (26/5110), giving a specificity of 99.5% (5,079/5,105). Over the same period, the true positive rate was 16% (5/31).
Most people no longer need to take a coronavirus test. You can still access testing if you have a health condition which means you're eligible for coronavirus treatments. To prevent the spread of infection, you should stay at home and avoid contact with other people if you're unwell.
Risks. A COVID-19 diagnostic test can have a false-negative result. This means that the test didn't show you have the virus even though you do. You risk spreading the virus to others if you don't take care, such as wearing a face mask, when you're near other people.
