Evaporation lines

Of all tests recorded using this brand, 5.9% were reported as evaporation lines. This mean around 1 in every 17 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.

The first time I used these tests, it gave me clear negatives, but this last time both tests showed up faintly positive. But I know they wear false positives because my period showed up. I will never buy this brand again!

Used this pregnancy test and got what seemed to be a positive (blue light/thin plus sign, within the time limit) but all other tests showed negative. Blood test confirmed I was never pregnant. False positive.
