Clearblue is known for its early detection pregnancy tests. Clearblue provides a test which can detect pregnancy from as early as 6 days before your missed period day. The term “missed period day” is known for the day after you’re expecting your period. The Clearblue Early Detection Pregnancy Test can be used up to 5 days before the day you’re expecting your period also. If you are testing before your expected period, you are recommended to use the first urine of the day.
So What is The Detection Success Rate?
It has been proven that 79% of pregnancies have been detected using the Clearblue Early Detection Pregnancy Test. This number then increases to >99% from up to 4 days before your missed period day. It is important to remember when testing for pregnancy early, even if you read a negative result, you may still be pregnant.
The Human Chorionic Gonadotropin Hormone and Why it's Important.
Both at home pregnancy tests and blood tests detect the presence of a hormone known as Human Chorionic Gonadotropin (HCG). Once the embryo attaches to the lining of the uterus, HCG is produced, and the levels will rise rapidly throughout the first few days of pregnancy.
So, if you do a test and it is negative, it could be too early as your HCG levels may not be high enough to detect. You may have taken the test too early or have taken the test wrong. Each pregnancy test can vary on how soon they are able to detect the HCG in your urine, Clearblue being one of the earliest.
