Thanks, Cristina. I have been GF for 7 years. During the last 2 years, I have not been TRUE GF and am suffering the consequences. (Which is what prompted further testing and the MTHFR finding and possible Hashimoto’s diagnosis.) My husband nor I have been genetically tested for gluten sensitivity. I know my husband will not do the testing. I feel better when I am TRUE GF and do not want my son to suffer as I have. Is the HLA-DQ accurate/reliable for children (my son is 1 year).
