Evap Lines

Know your facts first before responding to someone's post.

An evaporation line is a slight streak that appears where the positive line on a pregnancy test should be. Evaporation lines are colorless streaks, not faint lines. They typically appear if a person waits for longer than the suggested time to read the test result. An evaporation line can also appear if the test gets wet. An evaporation line does not indicate that a woman is pregnant. These lines often occur when a person has checked the result too late or taken the test incorrectly.
