Re: differing doctor opinions on salivary cortisol

Thanks for posting that Feo :-)

That specific study you link is the one i remember that demonstrates the differences between people and their CBG (bound coritsol) levels.

By simply using blood analysis alone and using a standard formula to try to figure out the 'free' available cortisol levels, as this study shows, is not at all accurate in determining levels.

" Thus, an advantage of measuring salivary cortisol rather than total serum cortisol is that it eliminates the need to account for within-subject changes or between-subject differences in CBG." Tweet
