How do you know if an evaporation line is faint or positive?
It's also important to note that while an evaporation line appears faint, a faint test line on a pregnancy test doesn't automatically suggest an evaporation line. A faint positive test line can also appear if you take a pregnancy test shortly after implantation when your hCG level is low, or if your urine is diluted.
Can a pregnancy test turn positive after 30 minutes?
This usually ranges between a couple of minutes up until 10 minutes later. If you see a positive result beyond this time frame, you may be left second-guessing the results. However, the false-positive reading, in this case, is due to something called an evaporation line.
Do evaporation lines disappear with water?
Unfortunately, evaporation lines will not disappear, even when you try to remove them with water.

Why did my pregnancy test turn positive hours later?

As a result, the test may start to display a positive line. After the allotted time has passed, you should discard the pregnancy test to avoid confusion.
How does an EVAP line look like?
An evaporation line on a pregnancy test is a faint line (or rather, mark) caused by a test reaction that occurs when the urine evaporates, or when the test gets wet.

Determining whether a test line is truly positive or the result of evaporation can cause distress.
