How Long is a COVID-19 Test Result Valid?
A COVID-19 test result does not have a fixed validity period. It only indicates whether the virus was detected at the time of testing, so a negative result does not guarantee that you won't develop an infection later. If you have COVID-like symptoms but your rapid antigen test is negative, the infection may still be in its early stages. In such cases, repeat the test after 48 hours. A positive result generally indicates a COVID-19 infection. If symptoms persist despite negative test results, consult a doctor to rule out COVID-19 or other infections.
