Hi could someone tell me the best way to privately tests cortisol binding globulin levels please? I want blood tests done (not saliva) that will tell me my cortisol plus the cbg levels because I'm suspecting my symptoms of low cortisol are caused by high cbg levels prob caused by high estrogen. I also can't seem to find private blood tests for free cortisol levels.
However I'm having difficulty determining the best way to test this. I'm going to do several tests over my monthly cycle to compare my 'well' days and 'unwell' days. I live in the UK.
Your help with this is much apreciated. Thankyou
