Study Notes
Thyroid Hormone and Function Summary
- The thyroid gland efficiently takes up iodide from the blood and converts it into thyroid hormones, which are regulated by TSH through a negative feedback mechanism.
- Euthyroid refers to normal thyroid hormone production, regulated by TRH, and influenced by environmental factors such as temperature changes.
- Thyroid hormones control cellular metabolic activity, with T3 being more potent than T4, influencing metabolic processes, cell replication, brain development, and growth.
- Calcitonin, secreted by the thyroid gland, regulates plasma calcium levels by increasing its deposition in bone.
- Congenital hypothyroidism leads to intellectual disability and stunted growth, while hypothyroidism in adults leads to lethargy, weight gain, and slow body functions.
- Hyperthyroidism results in an increased metabolic rate, with symptoms often linked to increased response to circulating catecholamines and an enlarged thyroid gland or goiter.
- Assessment measures for thyroid function include palpation, auscultation, laboratory tests, thyroid scanning, biopsy, and ultrasonography.
- Serum immunoassay for TSH and free T4 levels are widely used tests for thyroid function, with free T4 levels correlating with metabolic status.
- Diagnostic imaging techniques like ultrasound, CT, and MRI can be used to confirm the results of other diagnostic studies.
- Thyroid tests involving iodine should consider patient allergies to iodine or iodine-containing medications, as well as medication use affecting thyroid function.
- Patients' previous reactions to iodine and shellfish should be determined for thyroid tests, as well as their use of iodine-containing medications and other medications affecting thyroid function.
- Serum Thyroid-Stimulating Hormone Measurement is the primary screening test for thyroid function.
