Thyroid #3 Extreme Blood Test Panel
The Thyroid #3 Extreme Blood Test Panel includes a Thyroid Profile with TSH, Tri-iodothyronine (T3) Free Serum, Thyroxine (T4) Free Direct Serum plus Thyroid Peroxidase (TPO) Antibodies, Thyroid Antithyroglobulin Antibody (TAA).
Thyroid #3 Extreme 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.
Thyroid Peroxidase (TPO) Antibodies - antibodies to thyroid microsomes (thyroid peroxidase) are present in 70% to 90% of patients with chronic thyroiditis. They are also present in smaller percentages of patients of other thyroid diseases. Antibody production may be confined to lymphocytes within the thyroid, and serum may be negative. Small numbers (3%) of people with no evidence of disease may have antibody. This is more frequent in females and increases with age.
Thyroid Antithyroglobulin Antibody - This test may be ordered to investigate the cause of an enlarged thyroid gland (goiter) and/or performed as a follow-up when other thyroid test results (such as T3, T4, and/or TSH) show signs of thyroid dysfunction. One or more thyroid antibody tests also may be ordered if a person with a known non-thyroid-related autoimmune condition, such as rheumatoid arthritis, systemic lupus erythematosus, or pernicious anemia, develops symptoms that suggest thyroid involvement. Such involvement may occur at any time during the course of the other condition(s).
