For pregnant women, this brand starts to give positive results for more than 80% by 12 days past ovulation. This means that at least 4 out of 5 pregnant women will get a positive result on 12 dpo or later.


By 13 days past ovulation this brand gives a 'standard' test result. Which means the test result is easily distinguished as a positive result (usually nearly as dark or as dark as the control line)

Evaporation lines

Of all tests recorded using this brand, 2.1% were reported as evaporation lines. This mean around 1 in every 48 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.

Unfortunately I get a shadow line 8/10 times with this test. It’s gotten my hopes up too many times. I wouldn’t use for early testing. Very misleading. 2 start because blue dye is 1 star.. even worse!

Very faint bfp at 9dpo. Faint at 10dpo with an hcg of 14.7mIU/mL. LOVE these tests.

This test gave me my first faint line at 9dpo. Even when a first response was negative!!! Next day I got a darker line with a positive clearblue digital as well.
