Hi Ryan,
I'm no expert on the subject but I'd suggest getting another test done (making sure you haven't exercised beforehand). Tell the Doc you're on a supplement or something & want to see if it's working. If the results come back the same as the first, then you can rule out the exercise theory & concentrate on looking for reasons down another avenue.
Someone here may have a better understanding of your problem & hopefully you can get a more direct answer.
