Ovulation test and conception targeting The LH Rapid Test (Urine) Ovulation Test Stick is a rapid chromatographic immunoassay for the qualitative detection of luteinizing hormone (LH) in urine to aid in the detection of ovulation. Ovulation is the release of an egg from the ovary. Just before ovulation, the body produces a large amount of luteinizing hormone (LH) that triggers the release of a mature egg from the ovary. This LH surge usually occurs in the middle of the menstrual cycle. The LH test can help predict the timing of ovulation and peak fertility. During this fertile period, pregnancy is more likely to occur. Advantages: Quick results Easy to read User friendly No equipment required High accuracy >99.9% Result in 3 minutes
