    Unraveling the Confusion over Saliva, Serum & Urine Testing for Steroid Hormone Levels

    Saliva vs. Urine vs. Blood:

    Serum (blood): for sex hormones there is no distinction in serum between bound and unbound (free) hormones. It can be misleading in which hormone levels appear as normal or even high normal because of the amount of bound hormones. If free hormone level is low, the patient can be functionally deficient even with normal total hormone levels.  Serum is ideal for testing hormones such as FSH, LH, prolactin, fasting insulin, and thyroid hormones including Reverse T3, as well as thyroid antibodies.  For sex hormones, serum testing has a more limited utility. I don’t recommend serum unless you are menopausal or close to it. 

    Saliva: Saliva test measures free, unbound, bioavailable biologically active hormones, which can be delivered to the receptors in the body’s tissues. Only unbound hormones are able to pass through into the saliva. Saliva is best used to evaluate cortisol and the balance and flow of the estrogens and progesterone in women who are still having menstrual cycles. This is a great affordable place to start on testing your hormone levels and is the gold standard for testing cortisol throughout the day.  Saliva measurements are greatly affected by the use of exogenous hormones. Transdermal progesterone and testosterone, in particular, can result in supra-physiological levels in saliva testing. Because of this if you are on HRT I recommend urine testing. 

    Urine: Gold standard of hormone testing! Measures the hormone metabolites and gives you the most comprehensive look at your hormones. Some estrogen metabolites have a protective effect on estrogen-sensitive tissues, other metabolites have a more carcinogenic effects. Measuring the hormone metabolites give us insight into what hormones are doing in the body. Analysis of 44 different hormones: estrogen, progesterone, testosterone, DHEA-S, and cortisol along with their metabolites. This is a more comprehensive test then saliva or serum. An important advantage of a 24-hour urine hormone collection is the ability to measure hormone metabolites. It is well-established that certain estrogen metabolites are “good” estrogens, having a protective effect on estrogen-sensitive tissues. Other metabolites are known to have more carcinogenic effects.

    If you are trying to choose which test is best the Advanced Urine Metabolite Test is the most comprehensive and affordable for what you get. 

    Listen to the podcast Karen did called “Everything You Need to Know About Hormone Testing.”

     

  • Advanced Urine Hormone Metabolites Profile (most popular)
