PCR tests are accurate nearly 99% of the time. Antigen tests don't pick up all COVID-19 infections, but timing is also important.
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).
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.
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.
Public Health England reports that RT-PCR assays show a specificity of over 95%, meaning that up to 5% of cases are false positives. The impact of false positive results includes risk of overestimating the COVID-19 incidence, the demand on track and trace, and the extent of asymptomatic infection.
At-home tests are accurate about 80% of the time. While 80% sounds decent for a grade on an algebra test, it's not perfect for a COVID-19 test. It means that 20% of the time — or 1 in 5 times to drive the math home — when a person is infected with COVID-19, the test is not picking up evidence of the virus.
Could it be a false positive? A: In general, a positive COVID-19 test means the patient has or recently had a COVID-19 infection (CDC, 2023). At-home false-positive tests for COVID-19 are uncommon. If the patient or provider wants to confirm an at-home test result, a PCR test can be considered to confirm infection.
If you're tested too soon after you were exposed to COVID-19, there may not be enough virus in your body for an accurate result. If this is the case at the time of the test, your test may come back negative, even if you actually have the virus. This would be considered a 'false negative' test.
Negative test If you're tested too soon after you were exposed to COVID-19, there may not be enough virus in your body for an accurate result. If this is the case at the time of the test, your test may come back negative, even if you actually have the virus. This would be considered a 'false negative' test.
In particular, false-positive testing is exceedingly uncommon, though false negatives occur among asymptomatic persons — such cases tend to have high cycle threshold values, suggesting lower viral loads.
