This panel was built specifically as a follow up panel to Dr. Amy’s Basic and or Thyroid plus panel. This panel offers is an excellent thyroid screening panel because it includes a TSH, Free T4 and Free T3 hormones.
After Dr. Amy has evaluated thyroid function with her basic panel or her plus panel, Dr. Amy recommends these tests for follow up testing. It is important to understand how important optimal thyroid function is for every cell and body system we have. Thyroid hormone production is regulated by a feedback loop between the hypothalamus, pituitary gland, and the thyroid gland. Hypothalamic thyrotropin-releasing hormone (TRH) stimulates pituitary thyrotropin (TSH) synthesis and secretion. In turn, TSH stimulates production and release of T4 and T3 from the thyroid gland. When enough T4 is produced, it signals to TRH and TSH that there is enough thyroid hormone in circulation and not to produce more. About 85% of the hormone produced by our thyroid gland is T4, which is an inactive form of the hormone. After T4 is made, a small amount of it is converted into T3, which is the active form of thyroid hormone. From years of clinical practice, Dr. Amy understands just how important each biochemical step of thyroid function and how best to evaluate it in order to help improve the health and well being of those she serves.
Test Preparation For Optimal Results:
- If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
- For optimal results, please fast for 10-12 hours prior to testing. Please be well hydrated, water only.
- Your test results should be finished processing in 7-14 business days.
- When your results have finished processing, a copy will be sent directly to you.
Your health care provider should evaluate a deviation from normal ranges.
