The Usefulness of TSH

by Romeo Mariano, MD (July 24, 2010)

Effect of Exogenous Thyroid Hormone Intake on the Interpretation of Serum TSH Test Results: http://www.thyroidscience.com/ hypotheses/ warmingham.2010 /warmingham.intro.7.2010.htm Here is the free PDF: http://www.thyroidscience.com/ hypotheses/ warmingham.2010/ warmingham.7.18.10.pdf I prefer monitoring actual thyroid hormone levels in addition to TSH (Thyroid Stimulating Hormone) for assessment and treatment, rather than relying on TSH alone. One major factor is that there [...]

Reducing dietary sodium: the case for caution.

by Romeo Mariano, MD (February 21, 2010)
