When you become pregnant, your body produces the pregnancy hormone, human Chorionic Gonadotrophin(hCG). The amount of hCG in your body doubles approximately every 2 – 3 days, and reaches a maximum at around 7 – 12 weeks into the pregnancy. It stays at a higher than normal level for the rest of the pregnancy, and for up to 3 weeks after giving birth. The level of hCG can be elevated above normal levels for up to 9 weeks if you have had a miscarriage or a termination.

The Clearblue Digital Pregnancy Test works by detecting the pregnancy hormone in your urine and is over 99% accurate when used from the day your period is due1. You can use it up to 4 days before your expected period2 but if you get a ‘Not Pregnant’ result, you should test again when your period is due. The levels of pregnancy hormone in your urine may not be high enough to be detected yet.
With a Clearblue Digital Pregnancy Test, an optical reader encased in the Test Stick interprets the result for you and shows your result in words: ‘Pregnant’ or ‘Not Pregnant’.
Pregnancy Test is quick and easy to use, and produces a result within 3 minutes.
