Thyroid function measurements are important in order to evaluate thyroid disorders, mainly to check hormone levels. It is used to screen for hyperthyroidism, hypothyroidism, and thyroid disorders such as Hashimoto’s thyroiditis.
The main thyroid-related hormones include: triiodothyronine (TT3), thyroxine (TT4), supersensitivity thyroid stimulating hormone (TSH), free T3 (FT3), free T4 (FT4), thyroid peroxidase antibodies (TPO-Ab), and thyroglobulin antibodies (TG-Ab). However, the items checked in the labs are not exactly the same for each hospital and each doctor when screening for thyroid disease in different patients, but they are generally within these seven hormones.
