What do drug test results look like?

My parents are getting divorced (I'm 14, my brother is 16), and my dad may be on drugs. he says he took the drug tests, and he showed the results to my brother, but not my mom (he says "She isn't entitled to his files anymore") or me (b/c I've been giving him the silent treatment b/c I hate him). Couldn't he just type it up himself, b/c he knows my brother doesn't know if it's official or not? What should he have looked for?
