This Ovulation Test allows you to predict when you will ovulate – the time you're most likely to become pregnant! This is a home-use test kit to measure Luteinizing Hormone (LH) in your urine. This helps detect the LH surge that happens in the middle of your menstrual cycle, about 24-36 hours before ovulation. LH is the hormone that facilitates ovulation (the release of the egg). When you detect your LH surge with an ovulation test, you know you are fertile. Our Ovulation Test is extremely easy to use and a very cost effective way of giving you and your partner the best chance of getting pregnant. What comes with the test?

Each test is individually packaged in a sterile, foil pouch with the expiration date clearly displayed and contains a desiccant to protect against moisture. All tests have a long expiry date. How accurate is the test? This Ovulation Test has been fully tested to 99% accuracy and hold full CE marking and are extremely accurate. For best results follow the instructions carefully.
