The Clearblue Rapid Detection Pregnancy Test is over 99% accurate (from the day you expect your period). Results in 1 minute: A "Pregnant" result can be seen in 1 minute when you test from the day you are late. Wait 3 minutes to confirm a "Not Pregnant" result. Features a colour-changing tip: The wide tip turns pink for easy targeting. How it works: When you are pregnant, your body produces the pregnancy hormone hCG (human chorionic gonadotropin). The level of hCG approximately doubles every 24 hours in the first few weeks, peaking at around 7 to 12 weeks of pregnancy. Clearblue Pregnancy Tests work by detecting tiny amounts of the pregnancy hormone in your urine and are over 99% accurate from the expected start date of your period.
