The Clearblue Digital Ovulation Test has been shown in extensive laboratory trials to be over 99% accurate in detecting the LH surge prior to ovulation. The sensitivity of the Clearblue Digital Ovulation Test is 40mIU/ml.

The number of Test Sticks in a Clearblue Digital Ovulation Test pack is sufficient for most women with regular cycles to detect their LH surge. If your cycle length varies by more than 3 days then it is possible that you may need to start a new pack to detect your LH surge. Some women do not ovulate each cycle and therefore will not see an LH surge in such cycles. If you are concerned about your results please see your doctor.

a. Always read the manufacturers’ instructions for any medication that you are taking before conducting a test.
b. Certain medical conditions and medications can adversely affect the performance of the Test: for example if you are actually pregnant, have recently been pregnant, have reached the menopause or have polycystic ovarian syndrome you may get a misleading result. This may also be true if you are taking fertility drugs containing Luteinising Hormone or human Chorionic Gonadotrophin. Please check with your doctor.

No, it will not affect your results. However your natural hormone pattern is disrupted by hormonal contraception and if you have recently stopped using it your cycles can be irregular and may take some time to stabilise. You may wish to wait until you have had two natural menstrual cycles, and note the length of these cycles, before using Clearblue Digital Ovulation Test.

It can take many months to become pregnant. There are many reasons why you may not become pregnant even if you’ve been able to have sex at your most fertile time. If after several months you’ve had no success, you should consult your doctor.
