Study Notes
Indications for Screening
- Neonates for congenital hypothyroidism
- Patients with autoimmune disease
- Individuals with strong family history of thyroid diseases
- Patients with suspected hyperthyroidism/hypothyroidism
- Conditions linked to thyroid disease, such as atrial fibrillation or anxiety disorder
Thyroid Function Tests
- Used to assess true metabolic status
- Most important test to assess function and monitor thyroid hormone replacement therapy
- Increased TSH indicates thyroid failure, characterized by decreased T3 and T4 levels
- Primary hypothyroidism is an example of thyroid failure
Surveillance
- Women with a history of postpartum thyroiditis
- Post-neck irradiation
- Post-destructive treatment (radioiodine or surgical) for thyrotoxicosis
Monitoring
- Monitoring treatment of hyperthyroidism with antithyroid drugs
- Patients with primary hypothyroidism taking thyroxine hormone replacement therapy
Serum Thyroid Hormones
- Thyroid Stimulating Hormone (TSH)
- Secreted by the anterior pituitary gland
- Increases production and release of thyroxine (T3 and T4) from the thyroid
- Its secretion is inhibited by high levels of thyroxine
