Clear Blue Pregnancy Plus Test-2 tests is as accurate as a doctor's urine test. It's over 99% accurate from the day your period is due. It's the NO.1 brand most recommended by doctors in UK research. Clearblue recommends that you test from the day your period is due. However, the pregnancy hormone increase rapidly in early pregnancy & Clearblue PLUS can be used to test up to 4 days before your period is due. In clinical testing with early pregnancy samples Clearblue PLUS gave the following results:-1 day before period is due
- 98% of samples from pregnant women giving a 'pregnant' result. 2 day before period is due
- 97% of samples from pregnant women giving a 'pregnant' result. 3 day before period is due
- 88% of samples from pregnant women giving a 'pregnant' result. 4 day before period is due
- 56% of samples from pregnant women giving a 'pregnant' result. If you test early & get a 'not pregnant' result it is possible that the level of pregnancy hormone may not yet be high enough to be detected. You should test again when your period is due.
