No. Can't imagine where that idea could have come from.
Thank you for the answer, but I meant does a person's age affect the outcome of a thyroid test. I have heard that age can cause a test to be incorrect because of the squed(sp.) effect of the curve which gives the result.
Yes it does. This is a quote from a good review of hormones in general.
"Hormones are the most powerful molecules in our bodies, controlling the function, growth reproduction, metabolism, and repair of every cell. Our bodies require optimal hormone levels, just as they require optimal levels of essential vitanutrients: vitamins, fats, amino acids, and minerals. Our hormone levels are generally optimal in our youthful years--our early twenties--but many begin to fall soon afterwards and continue to decline with increasing age. Hormone levels decline because our glands and the parts of our brain that control our glands deteriorate with age. This age-related hormone loss is natural, but it is not adaptive. It is destructive. It is one of the mechanisms of aging--our euphemism for the disease by which Nature causes our deterioration and death."
