Over 99% accurate2, easy to use and easy to read

At Clearblue® we believe that when a woman suspects she might be pregnant she needs a result she can be confident in and act on. That is why all Clearblue® pregnancy tests deliver over 99% accuracy from the day of your expected period2 ; they are designed to be easy to use and read, and can be used up to 5 days sooner than waiting until you miss your period (which is 4 days before the day you expect your period)3.

No tests are more accurate – All Clearblue® pregnancy tests are over 99% accurate2

So sensitive you can test early – All Clearblue® pregnancy tests can be used up to 5 days before your missed period.


Which type of pregnancy test to choose?

We know how important it is for you to be confident using and reading a pregnancy test – and of course, to trust the result. That’s why every Clearblue® pregnancy test is designed to be easy to use, easy to read and over 99% accurate at detecting pregnancy from the day of the expected period2.

There are other tests out there that fall short. For example, a study of 111 consumers in the UK has shown that women find strips and cassettes difficult to use and hard to read4.


When to take a pregnancy test?

Clearblue® recommends you test from the day you expect your period to start, however, because levels of hCG rise rapidly in early pregnancy, Clearblue® pregnancy tests are so sensitive they may detect pregnancy up to four days before your expected period (which is 5 days sooner than waiting until you miss your period)3.

Not all pregnant women who test before the day of their expected period will get a 'Pregnant' (positive) result. This is because the hCG levels in their urine may not yet be enough for the pregnancy test to detect.

If you test early and get a 'Not Pregnant' (negative) result – but you still suspect you are pregnant – we recommend that you test again on or after the day you expect your period.

However, even if you test early, you can be confident in the accuracy of a 'Pregnant' (positive) result with any Clearblue® Pregnancy Test. Please read full package insert before use. If you suspect you are pregnant, you should seek qualified prenatal care.

How pregnancy tests work?

All home pregnancy tests work by detecting the pregnancy hormone hCG (human chorionic gonadotrophin) in urine. HCG first appears in the urine around the time the fertilized egg implants into the uterus and is thought to be involved in the implantation process. Levels of hCG rise rapidly from the earliest stages of pregnancy (doubling approximately every 24 hours) and reach a peak around 8 – 10 weeks.

Clearblue® Pregnancy Tests detect very small amounts of hCG in your urine and are more than 99% accurate from the day of your expected period2.
