Anybody born before at least the 2000's had a Guthrie ("heel prick") test performed and the blood spot card filed away. These have been used for DNA tests by authorities already, and I wouldn't mind betting there are moves to digitise all of them at some point if they haven't started already.
Blood tests can reveal all sorts of chromosomal abnormalities.
