Do evaporation lines have color on pregnancy tests?
An evaporation line is a slight streak that appears where the positive line on a pregnancy test should be. Evaporation lines are colorless streaks, not faint lines. They typically appear if a person waits for longer than the suggested time to read the test result.
What is an indent on a pregnancy test?
An evaporation line is a faint line that appears after a negative pregnancy test has dried. Tests that show two line results have what are known as ‘indent’ lines where the ink pools. One line is for the control line and one is for the positive result (if there is one).
Are evaporation lines Blue?
Furthermore, an evaporation line is more easily confused with a positive on a blue test, since its dull grayish imprint is similar to that of a light blue line. Determining whether a test line is truly positive or the result of evaporation can cause distress.
What is an EVAP line pregnancy test?
An evaporation line, also commonly known as an “evap line,” is a term that describes any test line that appears after the time limit is up on a pregnancy test.
Will an evaporation line disappear?
Evaporation lines are lines on a home pregnancy test that are caused by evaporating urine in the pregnancy test window. When the urine on a home pregnancy test evaporates and begins to disappear and dry up, it can leave a very faint line.
How common are evaporation lines?
Evaporation lines are common and can occur with any pregnancy test. An evaporation line is a line that appears in the results window of a pregnancy test as the urine dries. It can leave a faint, colorless line. If you’re not familiar with evaporation lines, you might see this line and think you’re pregnant.
Can EVAP lines have color?
Evaporation lines are typically more on the grey side, yet they can collect some of the color (whether it be blue, pink, etc.) The best way to know if it is an evaporation line or a true faint positive is to keep track of when you looked at the test.
