Remember, with the exception of Dr. Justin Saya, Defy's medical director, none of us are physicians. To test, or not test, on the basis of what "we" can tell you, given only a snapshot of your labwork and a brief, general discussion of your symptoms, would be to put too much faith in the collective wisdom of the Forum. I'd urge you to pursue the question and test. You will have put your mind to rest.
Keep us posted.
