Guide to Other Thyroid Tests
Some physicians believe a consistent low basal temperature could be a symptom of an underactive thyroid.
Hi, I’m Dr. Mary Ann Block, Physician, Author and Medical Director of The Block Center in Dallas/Fort Worth. I’m here for About.com. In this video, I’ll go over some unconventional thyroid tests. Besides regular clinical evaluations, blood tests and imaging -- practitioners sometimes use other procedures and tests to identify thyroid disease. Some of these tests are considered controversial to mainstream doctors, but are used often by alternative and holistic doctors.Let’s start with saliva testing, which is becoming more popular. Saliva sampling is a pretty comfortable and easy method of testing hormones. By either spitting or swabbing saliva, the free level of hormone can be evaluated. And unlike blood test, you can often do a saliva test at home. Then, there is urinary testing for thyroid function. This is not nearly as popular as blood tests. But sometimes, when patients receive a normal blood test - despite significant symptoms - a urinary test can be done to evaluate T3 and T4 levels further. T3 and T4 are the main hormones released by the thyroid. The Iodine Patch test is another test that’s sometimes being done to evaluate thyroid conditions. It’s a controversial test that involves the painting of pure iodine solution on the skin. Some alternative physicians claim that faster the stain disappears, the more likely you are to have a lack of iodine. And lastly, there’s basal body temperature tests. Your basal body temperature is measured in the early morning, before you wake up and move around. Some physicians believe a consistent low basal temperature could be a symptom of an underactive thyroid.For more on thyroid disease symptoms, visit health.about.com. Thanks for watching.
