Question

How do pregnancy tests work?

Answer 1

There are different kind of pregnancy test but I assume you are asking about the common urine test. The urine test kit basically detects a chemical called as Human chorionic gonadotropin Hormone or commonly called as HCG in urine which is synthesised during pregnancy.

Answer 2

Answer 4

but in those tests they use antibodies against HCG with an enzyme, that's why it's possible to see it ;). http://webphysics.iupui.edu/webscience/bio_archive/images/gfpregtest2.gif
