Evaporation lines

Of all tests recorded using this brand, 1.3% were reported as evaporation lines. This mean around 1 in every 77 test results was an evaporation line. This is considered medium 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 vertical scraping from processing on the window makes it quite hard to see early positives on this test.

Small testing window that is well below plastic cover. This makes light reflect and difficult to see faint lines. I've used two of these tests, and both had fluff in the test window. I had to pop out the cover to see the window. Confirm (Australian version).
