Just remembered that the missus and I had to give blood for testing when we got married here. Still haven't a clue why and what they do with the results....no idea many years later if it's still compulsory or not.
Does anyone know if other countries make you go through the same procedure when you get married? Not that I was bothered at the time as I have my blood tested once a year at least anyway seen as OSDE pays for it anyway.
