I was diagnosed with Idiopathic Cerebellar Ataxia in 2018 and had all the usual tests which proved negative . My neurologist in Aberdeen recently managed to arrange a TG6 blood test in Sheffield . The result was 4.2 U/ML , and a result >4 is positive.I have none of the usual symptoms of celiac disease or gluten intolerance . I am aware that it is important that a gluten free diet must be very strict, and as I am at the beginning of this journey I would be very interested to hear from other people who have had a positive TG6 test and their experience of undertaking a gluten free diet either positive or negative
