The 7 items of thyroid function should be judged according to the results and compared with the normal reference value, the results and reference range may vary according to different hospitals and equipments, if they are all within the reference value range, they are considered normal. Abnormal values should be consulted with the attending physician.
The 7 items of thyroid function generally include TSH (thyrotropin), FT4 (free thyroid hormone), FT3 (free triiodothyronine), TT4 (total thyroxine), TT3 (total triiodothyronine), TgAb (thyroglobulin antibody), TPOAb (antithyroid peroxidase antibody).
In general, if TSH is significantly lower and FT4 and FT3 are significantly higher, and the patient has symptoms such as excessive sweating, irritability, and lethargy, it may suggest the presence of hyperthyroidism. If TSH is significantly elevated and FT4 and FT3 are significantly lowered, accompanied by symptoms such as emotional indifference, facial edema, and weight gain, it may indicate the presence of hypothyroidism.
TgAb and TPOAb are important indicators for the diagnosis of autoimmune thyroiditis, and TgAb is important for the evaluation of recurrence of differentiated thyroid cancer.
Interpretation of the 7-item Thyroid Function Test should be done under the supervision of a doctor, and a doctor should be consulted if abnormal values are found in the test results.
