Clearblue Digital Ovulation Test with Dual Hormone Indicator detects oestrogen and luteinising hormone (LH) in urine. A surge in LH occurs just before ovulation and indicates you are at your most fertile time (Peak Fertility). A rise in oestrogen occurs a few days before this and indicates you are at High Fertility.
Unique & Effective: It is the only Ovulation Test that typically identifies 4 fertile days. The number of peak and high fertility days will vary from woman to woman. Using this test to identify your most fertile days can help you get pregnant faster than not using any method.
Accurate: Over 99% accurate in detecting the LH surge. Hormones are a more accurate predictor of ovulation than basal body temperature which only rises after ovulation.
