They reserve the right to sequence your DNA in the fine print last time I went to give blood over a year ago.
Presumably it's for medical research but that doesn't mean it similarly gets bought/sold for another purpose, sooner or later and possibly in bankruptcy like 23andme as mentioned by the parent poster who cared enough that I figured I'd warn them about less intuitive similar risks.
I think I have started to see similar language at doctors office paperwork recently but maybe I am misremembering. If you care about not getting sequenced, you have to read the fine print nowdays.
