Pregnancy test results can fade over time but they do not typically disappear. The initial reading should be taken within the time frame specified in the test instructions, usually within a few minutes. Fading can occur due to the evaporation of urine, which can lead to an evaporation line that may be mistaken for a result. For accurate results, always read the test within the recommended time.
