Before the 1980s, it took a visit to the GP for most women to confirm their pregnancy. Only laboratory assays could check for an increase in the hCG hormone indicating pregnancy, leaving women beholden to family doctors to find out if they were to have a baby.
The effect of this was to take control of their pregnancy out of the woman’s hands and put it in the hands of a (potentially unsympathetic) third party.
At-home pregnancy tests did exist, but were unpopular because they comprised several steps, took two hours to find out the result, were delicate to perform.
The invention of the first one-step pregnancy test, by a team including Mologic co-founder Paul Davis, can fairly be described as a revolution in women’s health.
