What does it mean when a pregnancy test stick shows two lines?

This situation may indicate pregnancy. Pregnancy tests typically detect human chorionic gonadotropin (hCG) in urine to determine whether a woman is pregnant. A positive result is indicated by the appearance of two lines on the test strip, suggesting possible pregnancy. However, if one of the lines appears faint or unclear, this may represent a false-positive result, and retesting after three days is recommended. While home pregnancy tests can provide an initial assessment of pregnancy, a definitive diagnosis requires a clinical early-pregnancy evaluation at a healthcare facility.
