Clearblue Rapid Detection Pregnancy Test is designed to be the easiest to use home pregnancy test, with wide, colour-changing tip and ergonomic shaped handle. With the accuracy you expect from Clearblue, you can get a result as fast as 1 minute - a 'pregnant' result may appear in 1 minute when testing from the day of your missed period. You should wait 3 minutes to confirm a 'not pregnant' result. It's over 99% accurate from the day of your expected period and can be used from 5 days before your missed period (which is 4 days before your expected period).
In lab testing, pregnancy detection rates were: 98% one day before the expected period, 97% 2 days before, 88% 3 days before, and 56% 4 days before the expected period. In a UK study, over 9 in 10 women said they would pay more for plus than a strip test (based on 111 women using and reading different test types).
