Evaporation Lines and Early Pregnancy Tests

Evaporation Lines and Early Pregnancy Tests

What are evaporation lines?

Evaporation lines. You might not have heard about them before, but they are quite common. 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. The line is usually colorless, and very faint, and can appear on any pregnancy test. Sometimes evaporation lines can appear in the result window where a positive or negative result is, which can be confusing for some women to interpret.

Taking a test too early

If you take a home pregnancy test too early, sometimes a very faint line can develop in the test window. If you see a faint colored line in the test window, that should not be confused with an evaporation line. An evaporation line will be colorless. If you do see a faint colored line, it could be that you may or may not be pregnant and that your body hasn’t had enough time to build up enough hCG in your body.

Waiting too long to read results

If you wait too long after the test period is over to read the results, your results may be misread due to an evaporation line. Evaporation lines can also look very similar to a positive pregnancy test result, so it is very easy to misread them. If you take a home pregnancy test, it is very important to make sure that you read the instructions very carefully to make sure that you read the results within the allotted time frame.

Chemical makeup of urine

Each person’s urine has a different unique chemical makeup. Some women’s urine will be more likely to develop an evaporation line than others. Some evaporation lines can show up almost immediately, some may take a few minutes or even hours to develop, and some may never even develop at all.

Test and retest

Evaporation lines can make it every difficult and confusing to read a home pregnancy test. If you think that you see a line on a home pregnancy test that could possibly be an evaporation line, your best bet is to get another test and retest. Also, make sure that you read the results within the allotted time frame.
