Percutaneous progesterone delivery via cream or gel application in postmenopausal women... - 0 views

  •  
    Topical hormones best evaluated via saliva and/or blood spot. Urine and particularly serum does not increase with dosing.  That does not mean the topical hormone therapy is ineffective, just that serum and urine are not optimal to follow topical therapy.  When looking at endogenous hormones without any therapies: serum, saliva, urine, and blood spot are equivalent.

  •  
    this study of 40 obese patients found saliva cortisol testing less specific than urinary; but more than Dexamethasone suppression test.  The problem with this is several fold: first, this is done via ELIZA and not Mass Spec and second, 24 hour urine collection is hard to achieve in real life.

Transdermal delivery of bioidentical proge... [J Pharm Pharm Sci. 2010] - PubMed - NCBI - 0 views

  •  
    Transdermal progesterone levels are quickly transported to saliva.  This quick transport, while serum doesn't equally reflect progesterone, has puzzled many.  Theories have been proposed, yet no answers.   This study looked at whether 5alpha reductase expression in the skin would metabolize the progesterone  and this explain the difference in the two test mediums.  The authors of this study concluded that 5alpha reductase is the not the reason for the difference found in saliva and serum.  the same can be applied to urine as well.

  •  
    low cortisol is a frequent finding in chronic fatigue syndrome.  However, in the urine, the cortisol levels may be normal.  This is a reflection of increased metabolism of cortisol.  This is not a contradiction, but a metabolic effect.

  •  
    Glyophosate found to be increased in the urine of animals and humans eating GMO food products.  Interesting association that "ill" humans had higher urinary glyophosate levels.  What is defined as "ill" is left to be determined. But clearly, glyophosate is not the innocent product that we have told it was.
