Customer Reviews

TTC
These tests do work. I've had a confusing time with these tests. The tests state that if you read them after 5 minutes you can get a false positive. I had assumed I was getting a false positive because I was reading the tests after 5 min & getting a very weak positive.

I figured these were just cheap tests when I got my period any way, but it turns out I had a very early miscarriage that I was only aware of b/c we were trying to get pregnant.

I did an experiment after I knew I was no longer pregnant & read the test after 5, 15, & 45 minutes...no "false" positives this time as the directions state you may get. So if you are TTC these tests are worth the price & the LH ovulation tests this company makes work to. So I have to change this to 5 stars not 3.

cheap, work as well as my other pregnancy test strips
These work well and they're cheap. They're great just to have on hand whether you're trying to conceive or not. I bought some other pregnancy test strips that go down to 10mIU and these work just as well. You can use the package they come in as a "cup" (note: these are strips that need to be dipped, they aren't midstream pregnancy tests).

Evaporation Line = Postive
These tests do work. Like the previous reviewer stated, an early positive result will take longer than 5 minutes to show up and the line will be faint. I've never gotten an evaporation line while using these tests. Like other pregnancy tests, the positive line will get darker as the HCG levels increase.
