The LH One Step Ovulation Test is a rapid immunoassay for determination of Luteinizing hormone (LH) in human urine to help women predict the time of ovulation and peak fertility.
Ovulation is the release of an egg from the ovary. The egg then passes into the fallopian tube where it is ready to be fertilized. Immediately prior to ovulation, the body produces a large amount of luteinizing hormone (LH) which triggers the release of a ripened egg from the ovary. The LH Ovulation Rapid Test detects the LH surge in urine, signaling that ovulation is likely to occur in the next 24-36 hours.
