Peer-Reviewed Studies of Salivary Sex Hormone Testing
2012 – Salivary hormone measurement using LC/MS/MS: specific and patient-friendly tool for assessment of endocrine function.
Saliva has recently been attracting attention as a patient-friendly available bio-fluid and an alternative to serum/plasma for hormone tests. LC coupled with atmospheric pressure ionization-MS/MS, especially electrospray ionization (ESI)-MS/MS, has been recently valued as a highly specific method in the analysis of salivary hormones. In this article, LC/ESI-MS/MS assays for salivary hormones are overviewed according to the papers that have been published during the last 5 years. Practical derivatization to enhance the detectabilities of hormones in ESI-MS/MS is also discussed, because a major disadvantage of using saliva is low hormone concentrations.

2009 – Salivary sex hormone measurement in a national, population-based study of older adults
This study was “the first large, population-based study of older adults to measure salivary estradiol, progesterone, dehydroepiandrosterone (DHEA), and, in women, testosterone.”
The researchers analysed self-collected saliva specimens from 2,772 U.S. men and women, from 57-85 years old.
Conclusion: “These data demonstrate a high cooperation rate with in-home salivary specimen collection from older adults and good validity of sex hormone measurements.”

2009 – Simultaneous determination of salivary testosterone and dehydroepiandrosterone using LC-MS/MS
The researchers measured testosterone and DHEA levels in saliva using the liquid chromatography-electrospray ionization-tandem mass spectrometric (LC-ESI-MS/MS) method to determine if hormone levels were sufficiently accurate to screen for late-onset hypogonadism (LOH), i.e., insufficient testosterone.
Conclusion: Saliva testing was found to be 98.5-101.8% accurate in measuring testosterone and DHEA levels, and “thus, the developed method has satisfactory applicability in the diagnosis and medication for LOH.”

2007 – Salivary testosterone: a reliable approach to the diagnosis of male hypogonadism
The researchers studied whether measurements of salivary testosterone (Sal-T) matched measurements of serum (blood) free testosterone. They compared the Sal-T and serum testosterone levels in 20 men with hypogonadism (insufficient testosterone) and 52 men with normal testosterone levels.
Conclusion: “The results support the inclusion of this biomarker [salivary testosterone] as a noninvasive approach in the diagnosis of male androgen deficiency.”

2006 – Validation of salivary testosterone as a screening test for male hypogonadism
The researchers performed two studies of saliva testing to screen for male hypogonadism, i.e., insufficient testosterone levels.
The first study of 1,454 men found expected age-related testosterone variance by age.
The second study found that “salivary testosterone was strongly correlated with bioavailable testosterone, … calculated free testosterone, … and total testosterone.”
Conclusion: “These studies support the use of salivary testosterone as an acceptable assay for screening for hypogonadism.”
