This website will help you a lot, from the Mayo Clinic:

The page also mentions how TB can affect the adrenals.  Just as an aside, seems like I recall they're using some newer drugs to help with Parkinson's.

Sadly every lab in every country differs so it would have to be on the lab slip.

There is no way I can guess.
