One-Step Strip Style LH Urine Ovulation Test


One-Step LH Urine Ovulation 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 again. Please refer to the chart to determine when you should start testing. If your 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 the first day of your 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.

1. DO NOT use first morning urine samples as LH is synthesized in your body in the early morning. You may not get an accurate reading until later in the day.
2. The best time to collect your urine is between 10am - 8pm.
3. Collect the urine about the same time each day.
4. Reduce liquid intake about 2 hours before collecting your urine as a diluted urine sample can prevent the test from detecting LH surge.


1. Make sure the LH test strip is at room temperature.
2. Remove the LH test strip from the container.
3. Immerse the strip into the urine with the arrow end pointing towards the urine. DO NOT immerse past the "MARK" line. Take the strip out after 5 seconds and lay on a clean, dry, non-absorbant surface. (e.g.,mouth of urine collection container)
4. Wait for colored bands to appear. Depending on the concentration of LH in the test speciman, positive results may be observed in as short as 40 seconds. However, to confirm negative results, the complete reaction time (10 minutes) is required. DO NOT read results after 30 minutes


LH SURGE: If two color lines are visable and the test line is equal to or darker than the control line, you will probably ovulate within the next 12-48 hours.

NO LH SURGE: Only one color line appears on the control region or the test line is lighter than the control line. There is no LH surge.

Invalid: No visible line in the control region. Repeat test using a new test strip.
