The Clearblue Digital Ovulation Test detects the rise of the ovulation hormone LH (luteinizing hormone) 24-36 hours prior to ovulation and identifies the 2 best days to conceive in a given cycle. It’s more accurate than calendar and temperature methods and gives you unmistakably clear results on a digital display. The simple urine ovulation test is over 99% accurate at detecting the luteinizing hormone (LH) surge.
