The One Step LH Ovulation Urine Test is fast and easy to use. It is a qualitative test that can predict when there is a LH (luteinizing hormone) surge, and in turn, when you are likely to ovulate.

 First, you must determine the length of your menstrual cycle. This is the number of days from the first day of your menstrual bleeding to the day before your next bleeding begins. Please refer to the chart to determine when you should start testing. If you cycle is shorter than 21 days or longer than 38 days, consult your doctor. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days. Perform 1 test each day over a 5 day period, or until the LH surge has been detected.

No LH Surge: Only one color band appears on the control C line or  the T line is lighter than the C line. There is no LH surge.

LH Surge: If two color bands are visable and the T band is equal to or darker than the C band, one will probably ovulate in the next 24-48 hours. If one wants to be pregnant, the best time to have intercourse is after 24 but before 48 hours.

Invalid: No visible band at all. or  only a test band appears without a control band, the test should be repeat using a new test.
