Re: tufts and seasonal rise
Eleanor Kellon, VMD
The seasonal rise exists and has been well documented. It will influence both baseline ACTH and TRH response tests. We have a better feel for how baseline ACTH is influenced but there is also information on TRH response tests during the seasonal rise. I don't know exactly what you were told but it may have been that we can still interpret test results during the seasonal rise. If it was something else, they're wrong.
