The TSH test changed about a decade ago, making it much more sensitive. A number of studies have shown that the false negative rate is now at most a few percent, even with congenital hypoT. Of course, that doesn't guarantee that all doctors know how to interpret the results, especially when they are borderline, but there are other conditions that cause our symptoms besides hypoT. And, no, I don't believe that most Americans are deficient in iodine. The last CDC study (1995) showed that only about 12% in the U.S. were below the recommended dietary levels, at risk rather than deficient. While this is an increased percentage over the previous study, much can be explained by changing food processing and less use of iodized salt. Too many are using sea salt!! The World Health Organization standard for defining a deficient population is 20% below the dietary recommendation. WHO lists 130 countries as at risk, with an affected population of 2.2 billion. There is a map here, showing the places that are considered at risk due to the lack of iodized salt. http://www.iccidd.org/pages/iodine-deficiency/where-is-the-problem.php Chuck Quote Link to comment Share on other sites More sharing options...
