Are evaporation lines blue on clear blue?
On a blue dye test, the line can appear as gray or even a lighter shade of blue. (Note: For some reason, anecdotally, many mamas find that blue dye tests are more prone to evaporation lines.) Sometimes, though, the evaporation line appears as a colorless streak, almost like an indentation.
Do Clear Blue pregnancy tests have evaporation lines?
Just wanted to put that out there – evap lines definitely DO happen and they CAN be blue and look very much like a positive, but it's not actually a positive. Good luck everyone!
How common are evaporation lines?
An evaporation line on a pregnancy test is basically a false positive. While true false positives and false negatives are fairly rare,1 the evaporation line is the closest most women will come to having an error on their pregnancy tests.
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. If you are not confident with the pregnancy test result, it's highly recommended that you take another test, taking care to follow the instructions properly, to avoid a false positive pregnancy test result.
Can a pregnancy test change to positive after 10 mins?

Sometimes this line appears in the test window, making it look like a faint positive result. Evaporation lines are colorless streaks, not actual lines.
When do EVAP lines show up?
Evaporation lines are common on pregnancy tests, but they don't appear every time. It depends on the chemical makeup of each woman's urine. One of the best ways to avoid any confusion when using a home pregnancy test is to check your results within the reaction time.
How long do evaporation lines stay on the test?

Can an evaporation line be 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.
Do all pregnancy tests turn positive after 10 minutes?
If you check your results within the recommended time frame and see a faint positive line, you're most likely pregnant. On the other hand, if you miss the window for checking the results and you don't check the test until 10 minutes later, a faint line may be an evaporation line, which means you're not pregnant.

Can a pregnancy test turn positive after an hour?
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.
Will a pregnancy test turn positive after sitting?
If you let the test sit too long the the test may show a false positive result. A false positive is when the tests shows you are pregnant when you actually are not. Pregnancy tests work by detecting a hormone called human chorionic gonadotropin, HCG.
