TSH is a hormone produced by the anterior (frontal portion) pituitary gland, in response to low levels of circulating thyroid hormone (T4 and T3), as it stimulates the thyroid to produce additional T4 (which is converted to T3).
Dr. Morse has found TSH, T4 and T3 to be sometimes highly inaccurate indicators of thyroid function. TSH by itself, however, can be useful as an indicator of pituitary gland function.
For maximal accuracy, combine this test with:
- Basal body temperature test.
- Checking for signs and symptoms of multiple glandular weaknesses.
- In both irides: Check for chronic bowels or radii solaris in the 11 o’clock to 1 o’clock region.
Indicator(s):
If experiencing symptoms of thyroid weakness, and TSH is low, consider pituitary gland weakness.
If experiencing symptoms of thyroid weakness, and TSH is normal or high, consider thyroid weakness without pituitary involvement.
If TSH is high, consider hyperactive pituitary gland.
