Started seeing a new doctor, I have been diagnosed with IBS-SIBO and mentioned to her my total exhaustion most days. Did a blood test for thyroid for the first time, results were:
TSH 1.440 uIU/mL (reference: 0.450-4.500, interpretation: normal)
Triiodothyronine, Free, Serum 2.8 pg/mL (reference: 2.0-4.4, interpretation:normal)
T4, Free (Direct) 1.45ng/dL (reference: 0.82-1.77, interpretation: normal)
TPO ab 12 IU/mL (reference: 0-34, interpretation: normal)
Thyroglobulin Antibody 1.3 IU/mL (reference: 0.0-0.9, interpretation: high)
Based on my thyroglobulin Antibody results, she recommended me start on a low dose of Levothyroxine (25 mcg tabs) I tried to do research online about my TG antibody levels, and even though the test results say high, it seems like according to other charts the are normal?
