How do pregnancy tests work for beginners?

How does a pregnancy test work? All pregnancy tests detect the hormone human chorionic gonadotrophin (hCG), which starts to be produced around 6 days after fertilisation. Most pregnancy tests come in a box that contains 1 or 2 long sticks. You pee on the stick and the result appears on the stick after a few minutes. Pregnancy tests work by detecting the presence of the hormone, human chorionic gonadotropin (hCG). hCG is a hormone produced by cells in the placenta. Its production starts from the point at which the developing embryo attaches to the uterus, 6-12 days after conception.
