Understanding Your Pregnancy Test
What is a faint line?
A faint line - even barely visible - usually means pregnancy hormones (hCG) were detected. Any colored line counts as a positive result.
Evaporation lines
A colorless gray mark appearing after the reading window is an evaporation line - not a positive. Learn how to tell the difference.
Testing too early
A negative result before your missed period is often not reliable. hCG levels need time to rise to detectable levels.
