Evaporation lines

Of all tests recorded using this brand, 12.5% were reported as evaporation lines. This mean around 1 in every 8 test results was an evaporation line. This is considered high risk.

Only pregnancy test results reported by pregnant women are included. Therefore any negative results are false negatives.

A false negative result is when a pregnancy test indicates that you are not pregnant but you actually are. False negatives usually occur because there is not enough hCG in your system to be picked up by the pregnancy test. This can be caused by the test being taken too early, test sensitivity, diluted urine or failure to follow test instructions. To avoid inaccurate results you should try to wait as long as possible before testing.

What women think of this brand.

Got an evaporation line that I thought could be a positive result on the second test I used of Crystal clear. All other tests using different brands the following day said BFN. Disappointing!

got negative results on 10 other tests and blood but got positive on crystal clear with a faint blue line which appeared in the first minutes.

Got a faint false positive (DH saw it too!) and ran out to buy a more reliable brand. BFN. Found out with an OPK that I was ovulating and therefore couldn't possibly have hcg in my system. Definitely an evap line, not a light BFP. STAY AWAY! They're horrible!
