How Pregnancy Tests Work to Accurately Determine hCG

When you become pregnant your body starts to produce the pregnancy hormone, human Chorionic Gonadotrophin(hCG). The amount of hCG in your body doubles approximately every 2 to 3 days, and reaches a maximum at around 7 to 12 weeks into the pregnancy. Clearblue® Easy Pregnancy Tests work by detecting the presence of hCG in your urine.
