Dye Run on a Pregnancy Test: What It Means and When to Retest
A dye run can smear the result window and make the test hard to interpret. Here's what to do.
What a dye run looks like
A dye run often looks like smudging, streaking, or uneven color bleeding through the result area, instead of crisp lines. This can happen for multiple reasons (test handling, too much urine, manufacturing variability).
Treat smeared tests as inconclusive
When the result window isn't clear, the safest approach is to treat it as uncertain and retest with a new strip. Follow the instructions closely to avoid invalid results.
Photo enhancement can't fix a broken test
Your app can help document what happened, but it shouldn't be used to 'decode' a severely smeared window. The best move is usually a clean retest.
Retesting plan
If you're early, retest in 48 hours. If your period is late or symptoms are significant, seek confirmation from a healthcare professional.
