HOW DOES IT WORK? Unlike the traditional ovulation tests, in which the control test line differs in comparison to the test line each time -- quantitative test control lines normally will not change. This makes the test line that much easier and clearer to read. Women with PCOS, irregular cycles, multiple surges, and those with hard-to-recognize surges can benefit from the increased exactness of these tests and easily defined results. Instead of giving a positive or negative result, quantitative ovulation tests alone give a numerical LH level urine range from 2.5-80 mIU/mL. You can log the result manually or digitally scan and read results with the Premom app.
