My doctor ordered some lab tests after I had been
complaining of being VERY tired for several months. He said my TSH was a 4 which was considered subclinical hypothyroidism, especially for my age.
After seeing this he ordered further blood tests to check T3 Free, T4 Free, TPO, and TGAB. Everything came back normal except for my TGAB which was 16.7 with a reference range of 0.0-5.9.
