"Your urine’s too dark." He only knew that from the medical course Harry had taken a few years ago. Harry used to fill Tony in on random pieces from his lessons that were interesting. Many of their friends had asked why Harry was taking courses when he wasn’t going for a full degree, especially a course that discussed both magical and non-magical health issues. Harry’s response was because of curiosity. He didn’t want to be a healer or Auror Medic, but he figured that knowing some things would be useful considering Tony’s new job in no-maj law enforcement. It helped that once he was no longer under Snape and given time to learn the basics that Harry was rather good at potions. They rarely purchased potions now, Harry would rent out space at the local MACUSA office and brew them.
