I'm nothing if not determined to prove I have LPR reflux, as I simply cannot return to a normal lifestyle/diet without suffering through and through. Any evidence at all would go a long way for me to get LINK surgery! JustPassingThrough's Facebook page mentions an Exhaled Breath Condensate test for reflux, but I'm not sure of the details and searching it makes me more confused..! According to the staff at Peptest, it probably wouldn't find anything different from my spit tests and impedance. Is that true? If not, is there anyone in the UK who does this test?
