Its Smart Dual Sensor not only tells you in words if you are 'Pregnant' or 'Not Pregnant', it also tells you how far along you are. It's like 2 tests in 1. It first detects if the pregnancy hormone is present with over 99% accuracy from the day of your expected period and if you are pregnant, it also indicates how many weeks since conception occurred 1-2 weeks, 2-3 weeks or more than 3 weeks (3+). The Weeks Indicator is 93% accurate in detecting when you conceived. So sensitive you can test up to 5 days before your missed period. Within 3 minutes your 'Pregnant' or 'Not Pregnant' result in words will appear on the screen.
The Clearblue Pregnancy Test with Weeks Indicator is the first and only test that is as accurate as an ultrasound scan at dating pregnancy.
Please always read the instruction leaflet carefully before doing a Clearblue Pregnancy Test with Weeks Indicator.
