In modern medicine, an evaporation line appears when urine dries on a pregnancy test, often causing a faint, colorless streak. It can be mistaken for a positive result, but unlike a true positive, it lacks clear color. Always read the test within the recommended time to avoid confusion.
From an Ayurvedic perspective, reliance is placed more on bodily symptoms than test strips. However, Ayurveda encourages patience, observation, and using natural indicators of pregnancy like missed periods and subtle energy changes before confirming through modern tests.
