Evaporation lines

Of all tests recorded using this brand, 3.5% were reported as evaporation lines. This mean around 1 in every 29 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.

Got a negative reault but when I looked again a couple of hours later there was a faint positive. This was definitely an evap as when I re-tested 2 days later it was still negative. Discard and don't look again after 30mins or you may get your hopes up!
