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.
We found positive percent agreement was 43.3% (95% CI 34.6%–52.4%), negative percent agreement 100% (95% CI 99.4%–100%), positive predictive value 100% (95% CI 93.5%–100%), and negative predictive value 89.9% (95% CI 87.5%–92.0%).
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. This is known as a false negative result.
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. Laboratory error is also a possible cause of false negative test results. Conversely, false positive reports are less common.
If you were exposed to someone who has COVID-19 and you do not have symptoms, wait at least 5 full days after your exposure before testing. If you test too early, you may have an inaccurate result. If you are in certain high-risk settings, you may need to test as part of a screening testing program.
There is a very small chance that this test can give a positive result that is wrong (a false positive result). A negative test result indicates that the virus that causes COVID-19 was not detected in your sample. A negative result is presumptive, meaning it is not certain that you do not have COVID-19.
A fainter line might indicate that you're less contagious, but no test can tell you whether or not you're contagious. Changing safety precautions depending on the faintness or darkness of a line is not recommended due to the range of variability in time and strategies with which people test themselves at home.
Test specificity was high for all RATs (97.9–100%). Conclusions: The risk of false negative results when using COVID‐19 RATs for self‐testing may be considerably higher than apparent in manufacturer reports on the TGA website, with implications for the reliability of these tests for ruling out infection.
Amphetamine and methamphetamine are the most commonly reported false positive drugs. More complex drugs can also show up incorrectly on drug screen results: methadone, opioids, phencyclidine, barbiturates, cannabinoids, as well as benzodiazepines were also reported in patients taking commonly used medications.
Simply ask if you can take another test. Many will have no problems accommodating your request. It helps to present evidence as to why you tested positive the first time. As already mentioned, a letter from a doctor or pharmacist regarding a prescription medication will help.
