Science Milestone: The science behind modern pregnancy tests

Key advances in antigen detection technology and antibody specificity allowed early at home pregnancy detection.

The first pregnancy tests required injecting a woman’s urine into rodents or frogs and waiting for the animals to ovulate to confirm a positive result. The advent of antigen detection technology and rapid antibody production eliminated animal-dependent testing and made it possible for women to test for pregnancy early and at home.
