"TB diagnosis now in doubt"

Treated for TB for 4 years and now it appears it might not be. When I say might every test has come back negative but as there are false positives and false negatives how is anyone supposed to know it's not maths surely when two negatives equals a positive. Well in my case it could be. Completely disillusioned with the all the medical staff. Answers very hard too come by and they are quite happy for me to have TB on my records. The doctor was quite happy discharging me when a secret interferon gamma essay test ( to everyone else that's a quantiferon gold test) came back negative . Upto now I'm still being investigated and are no where nearer finding out what it is. All I can confirm is no biopsy's were cultured yet with granulomas confirmed, no investigations into type of gramuloma I was treated for TB twice and over a 4 year period. I would then hence a warning for anyone attending North Manchester infectious disease to be extremely vigilant , don't take diagnosis likely, ask questions, ask for proof. We didn't but if we did we wouldn't be where we are now. My life has been ruined by this.
