When I was in school late 70s or early 80s one of my teachers brought in finger prick & blood type kit. I learned then & it was confirmed when I was pregnant.
I remember doing that! There were a few circles on a card... Some kind of reagent drops or something? It's been a while.
If only schools would get back teaching instead of trying to change people.
