The LH One Step Ovulation Test Device (Urine) has been tested with commonly known drugs and hormones including FSH (1,000 mIU/mL), TSH (1,000 µIU/mL), and hCG (10,000 mIU/mL). At the levels tested, none of these substances interfered with the expected test results. About Ovulation Ovulation is the release of an egg from the ovary. The egg passes into the fallopian tube where it is ready to be fertilized. In order for pregnancy to occur, the egg must be fertilized by sperm within 24 hours after its release. Immediately prior to ovulation, the body produces a large amount of luteinizing hormone (LH). This is known as the “LH surge” and usually takes place in the middle of the menstrual cycle. LH triggers the release of an egg from the ovary. The LH One Step Ovulation Test Device (Urine) is a complete system to help you predict the time of ovulation and peak fertility. It is during this fertile time that pregnancy is most likely to occur. The LH Ovulation Test Device (Urine) detects the LH surge in urine, signaling that ovulation is likely to occur in the next 24-36 hours. Important: The LH surge and ovulation may not occur in all cycles. A positive result means your urine contains the level of LH that would indicate you are beginning to ovulate. You can assume that you will ovulate within 24-36 hours. A negative result means that no LH surge has been detected and you should continue daily testing. Not every woman ovulates mid-cycle; therefore, you may not see a positive result during the first 5 days of testing. Continue testing with the LH One Step Ovulation Test Device (Urine).
