Free Thyroxine (Free T4): May be normal in early stages or subclinical hypothyroidism, but often low when hypothyroidism develops. Triiodothyronine (Free T3): Less commonly affected but may be low in overt hypothyroidism. Specific Lab Tests - Autoimmune Markers Anti-Thyroid Peroxidase Antibodies (Anti-TPO): Elevated in over 90% of patients. Anti-Thyroglobulin Antibodies (Anti-Tg): These are also commonly elevated in Hashimoto’s but are less specific and sensitive than Anti-TPO. Thyrotropin Receptor Antibodies (TRAb): Usually negative in Hashimoto's but are tested if there’s suspicion of overlapping Graves’ disease. Additional Lab Tests: Erythrocyte Sedimentation Rate (ESR): May be elevated due to inflammation. C-Reactive Protein (CRP): Typically normal but may rise with active inflammation. Normal Thyroid Measurements: Isthmus Depth: Less than 0.5 cm (approximately) AP Length (Lobe): Less than 2 cm (approximately) Length (Lobe): 4-7 cm (approximately) Width: 2.5 cm (approximately) Acute Diffuse Hashimoto Thyroiditis: Diffuse enlargement of thyroid gland Heterogeneous appearance of entire gland Numerous hypoechoic nodules (Giraffe Pattern) Diffuse hypervascularity on color doppler (Thyroid Inferno) Hyperechoic linear strands Chronic Diffuse Hashimoto Thyroiditis Small atrophic thyroid gland Heterogeneous appearance of entire gland Hyperechoic linear strands
