Timing is critical to ensure you receive a valid and reliable test result. If you did not complete the steps to read and input your result into the app within the 5 minute countdown window, you receive an expired test notification, and the result is recorded as invalid. The stability of the result is not reliable after 5 minutes. Therefore, we enforce that the result is read and recorded during this time to ensure we provide you with the most reliable result reading. Please perform a new test with a new nasal swab sample and test strip and be sure to read your result within the 5 minute window.
