What does one line and a faded line mean on a pregnancy test?

In a pregnancy test, one line typically indicates a negative result, meaning that no pregnancy hormones were detected. A faded line may suggest a weak positive result, which could occur if the test is taken too early or if the hormone levels are low. It's important to follow the test instructions carefully and consider retesting after a few days for more accurate results. If there are uncertainties, consulting a healthcare professional is advisable.
