Like other pregnancy tests that work through urinalysis, the Clearblue Easy Pregnancy Test detects the presence of human Chorionic Gonadotrophin (hCG), which is produced by the placenta during pregnancy. Levels of this hormone are highest in the morning, so home pregnancy tests are most accurate early in the day.
