Evap is the line that comes up past the time frame. As shown below. They will be clear or colorless. This will show up after the urine is dried. Which are false positives.

This here is showing a FAINT line. Which means you either tested too early or a possible chemical pregnancy. It will pop up in the 3-5 min time frame while the urine is still wet. But it DOES mean pregnant. It will also have color.

Now i keep seeing people call evap lines indents but that is not the same thing.

INDENTS are the lines that pop up when taking a test.
