What diseases does the eight-item thyroid function test check for?

Thyroid function tests (eight-item panel) are used to diagnose thyroid disorders, such as hypothyroidism, hyperthyroidism, and chronic lymphocytic thyroiditis. The details are as follows:

Patients exhibiting obvious symptoms such as exophthalmos (protruding eyes) or an enlarged neck are advised to visit a hospital for the eight-item thyroid function test to determine the exact cause. The eight-item panel includes thyroid-stimulating hormone (TSH), anti-thyroid microsomal antibody, triiodothyronine (T3), thyroxine (T4), free thyroxine (FT4), thyroglobulin, anti-thyroglobulin antibody, and free triiodothyronine (FT3). These tests help evaluate thyroid function and identify potential thyroid-related diseases.

Prior to testing, patients should stop consuming iodine-rich foods and avoid high-fat and high-protein foods to prevent interference with test results. If abnormal results are detected, prompt medical consultation at a hospital is necessary, followed by treatment under a doctor's guidance.
