How to Tell the Difference Between a Positive Pregnancy Test & An Evap Line

How to distinguish a faint positive pregnancy test from an evap

Now that you are aware of the signs of a false pregnancy test, let’s move on. But how do you know it’s really a positive pregnancy test if you see a thin line on a pregnancy test within the allotted time frame?

  • Don’t test too early. The earlier you test, the lowest your hCG levels will be. If you have a real squinter, test again in a day or two. As hCG rises, a true positive test will darken.
  • Take a more sensitive test. Different test types and brands have different hCG thresholds in order to display a positive result. (Our guide to the best pregnancy tests includes hCG thresholds by test brand.) Keep in mind that the downside of testing early is that you are more likely to find out if you have a chemical pregnancy. These very early miscarriages are quite common, they usually do not signify any kind of underlying fertility problem, and before the advent of highly sensitive pregnancy tests, women might have had chemical pregnancies without even realizing it.
  • Don’t over-hydrate. If you have been drinking a lot of water and/or urinating frequently, your urine may be too dilute for an accurate reading. It’s best to avoid drinking fluids for two or three hours to ensure that your urine is not too diluted. First morning urine is usually more concentrated than urine from random hours during the day.

    • What is an evap line and how is it different from a positive pregnancy test?

    A thin line known as an evap line (evaporation line) can be seen after a negative test has dried. The tests are still damp when they are read because they are typically meant to be read three to five minutes after they are taken. The urine in the test dries after this amount of time has passed.

    The outcome is shown as the ink moves across the screen. On occasion, a small amount of ink will unintentionally get caught in the indent line as it moves across the screen. This caught ink is drawn to the surface and darkens as the test dries and the urine evaporates.

    The results are only accurate in the time frame specified in the instructions, which is why the most crucial rule for getting a true positive pregnancy test is to not read them after the allotted time.
