I am a 42 year old female, and I have 8/9 symptoms for Hashimoto disease (don t notice much hair loss). I was tested for microsomal antibodies and the test showed 1.0, is that a negative test? My TG Antibody test was 564.1 which was flagged high, and my T4, T3, and other tests are all in the normal range. I keep hearing that I probably have autoimmune issues, which is a very vague statement, and I am not sure what that means. I have a mass in my right thyroid that is around 2.6 centimeters, and has had 3 biopsies, all negative, and they found 2 more on my left thyroid one .64 cent., and one 1.6 cent.., I just went to an endo Dr. On Monday, he ordered the microsomal test which just came back. If you could let me know if any microsomal antibodies on the test is positive or negative since is is 1.0, and any suggestions for my next step would be greatly appreciated!
