If you've served on active duty within the last 15(?) years, your DNA is on file at the DoD Repository, regardless of any security clearance. They're supposed to ask if you want it destroyed when you separate or retire.
For real fun try a Polygraph!
Wow I didn't know they did that and I was never asked if I wanted it destroyed or if it could be held/used. Hmmmm better go look into this
