Testosterone Saliva ELISA Kit

Saliva testosterone refers to the measurement of testosterone levels in saliva, representing the free (unbound and bioactive) fraction of the hormone that diffuses from blood into the salivary glands. Unlike serum total testosterone, which includes both bound and unbound hormone, saliva testosterone specifically reflects the biologically active portion that can exert physiological effects. This non-invasive method avoids the influence of protein-binding variations (e.g., in SHBG levels), making it a practical and direct marker of hormone activity.

In clinical and research settings, saliva testosterone is used to assess androgen status in both men and women, particularly in the context of reproductive health, aging, adrenal function, and hormone therapy monitoring. Its ease of collection makes it especially valuable for serial measurements, at-home testing, or studies requiring multiple time points (e.g., circadian rhythm or stress-related hormone fluctuations). Saliva testosterone is also used in behavioral and psychoneuroendocrinology research, where hormone levels are correlated with mood, aggression, cognition, or sexual function. While not yet universally adopted in clinical practice, it offers a promising, accessible alternative for assessing functional testosterone activity.
