Thyroid #2 Essential Blood Test Panel includes:
Thyroid Panel with Thyroid-Stimulating Hormone (TSH) - Thyroid function is crtical to your metabolism and affects your energy level, heart rate, weight control, and more. The thyroid-stimulating hormone is produced in the pituitary gland and stimulates the production of thyroid hormones. The TSH helps identify an underactive or overactive thyroid state. This comprehensive evaluation of your thyroid hormone levels includes: T-3 Uptake, T4, Free Thyroxine Index (T7), and Thyroid-Stimulating Hormone (TSH).
Free T3: Test for evaluating thyroid function and assessing abnormal binding protein disorders.
Free T4: Free T4 may be indicated when binding globulin (TBG) problems are perceived, or when conventional test results appear to be inconsistent with clinical observations. It is normal in those with high thyroxine-binding globulin hormone binding who are euthyroid (i.e., free thyroxin should be normal in nonthyroidal diseases). It should also be normal in familial dysalbuminemic hyperthyroxinemia.
