A home ovulation testing kit, Clearplan, that detects the urinary luteinizing hormone (LH) surge was compared with basal body temperature (BBT) charts and cervical scoring as a method of ovulation prediction in 54 consecutive patients. The accuracy of all these methods was evaluated using daily serum LH measurements. Clearplan was shown to be significantly more accurate at timing ovulation than were BBT charts ( P < 0.0001) and cervical scoring ( P < 0.025). In 82%‐88% of cases the kit predicted ovulation within one day and in 89%‐96% of cases within two days of the serum LH surge. The kits were found to be easy to use and their potential place in clinical practice is discussed; home ovulation testing may ultimately replace serum LH assays as the method of choice in timing ovulation.
