Faint Pink Line on Pregnancy Test: Positive Result or Evaporation Line?

A faint pink line appearing within the test's read window (usually 3–10 minutes) on a sensitive test likely indicates early pregnancy (low hCG). However, an evaporation line—a colorless/gray streak appearing after the window as urine dries—can mimic a positive.

How to Distinguish

• True positive: Pink/blue (per test dye), appears within time limit, has thickness/color consistent with control line.
• Evaporation line: Colorless, thin, appears after recommended read time; no dye pigment.

Confirmatory Steps

1. Repeat with first-morning urine in 48 hours (hCG doubles ~48h early pregnancy).
2. Use a digital test ("Pregnant/Not Pregnant") or higher-sensitivity brand.
3. Quantitative serum β-hCG for definitive answer and viability tracking.

If prior miscarriage, consult provider for closer monitoring.
