Evaporation Line Clear Blue Pregnancy Test


What Is An Evaporation Line on a Clear Blue Pregnancy Test?

The Evaporation Line on a Clear Blue Pregnancy Test is an indication of hCG present in the body. The hCG hormone is produced when a fertilized egg is implanted into the uterus. It is the same hormone that pregnancy tests measure to determine whether the woman is pregnant. When a woman takes a Clear Blue Pregnancy Test, the test will indicate any presence of hCG by producing a line. This line indicates the presence of hCG; but, this line will eventually evaporate, leaving an indication or ‘evaporation line’ that does not indicate a positive pregnancy test result.

How To Spot an Evaporation Line on a Clear Blue Pregnancy Test

– Check the test within the manufacturer’s suggested time frame (5-10 minutes)
– Look for a faint line
– Compare the current test with a new one
– Evaluate the line’s color

When looking for an evaporation line on a Clear Blue Pregnancy Test, it’s important to consider the age of the test, as well as the color of the line. To be reliable, the line must be faint (not prominent) and the same color as the test results control line. The change in intensity of the ‘evaporation line’ indicates the presence of the hCG hormone.

What to do if there is an Evaporation Line on a Clear Blue Pregnancy Test?

If you have a faint or evaporation line present on your Clear Blue Pregnancy Test, it is important to take another test to confirm the results. The best approach is to wait a few days and retest with a new test. Be sure to read and follow the manufacturer’s instructions carefully and use first morning urine for best results.

If a positive result shows up on the second test, it is likely that you are pregnant. However, if both tests indicate that the line has faded, then it is probably an evaporation line, and not a positive pregnancy test result. In this case, you should consult with your physician to ensure you receive the care that you need.

Remember, an Evaporation Line on a Clear Blue Pregnancy test is a sign of the detecting hCG in the urine. Fading of the line is normal, but a new test should be taken to confirm the result.
