One other factor: a few days before my first test on 4/26, I did my annual blood work. I got the results back yesterday after I got my 5/3 test results showing the 1.07 equivocal index reading. The annual blood work showed that the presence of Thyroglobulin Antibodies were highly abnormal. This occurred on my last blood test, although the numbers weren’t high. My doctor believes it might be Hashimoto’s (sp?) Disease or or some other autoimmune disease.
