Iodine Patch Tests
This is a test that involves painting a patch of a pure iodine solution on the skin, and determining how quickly the stain on the skin disappears. This test is reported to be a measure of iodine deficiency, and rapid absorption of the iodine is supposed to indicate iodine deficiency. This test is used by some alternative practitioners. It’s generally considered quite controversial, however. Physician David Derry, M.D., Ph.D. has talked about this test here at the About.com Thyroid site.

Basal Body Temperature Testing
Typically, basal body temperature (BBT) testing involves measuring the early morning temperature, before movement, over time. In Hypothyroidism: The Unsuspected Illness , Dr. Broda Barnes’ groundbreaking book on thyroid disease, Barnes advocated use of this test as a diagnostic tool. According to Dr. Barnes, a basal temperatures consistently below 97.8 was a possible indicator of low thyroid function. A small percentage of alternative practitioners rely on basal body temperature results as their primary means of diagnosis. Other alternative practitioners feel that it may be one criterion among several to consider in diagnosis. Most conventional practitioners do not consider the test useful in thyroid diagnosis.
