Dear frieds,
I have read a fair amount about thyroid issues and there is one school of thought, and a credible one, that current thyroid tests do not pick-up hypo-thyroidism at a sub-clinical level although; that sub-clinical level may have just as profound effects as one with a clinical diagnosis. What I mean by sub-clinical is a thyroid function that is sub-normal BUT is not measuerable with current testing methods; think of it as a tumor too small to be detected with a mamograph.
I have attached an article on testing for sub-clinical thyroid preformance:

Although this article is on a supplier's website, I believe it has merit.
