Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — DHEA S testing

Female hormone profiling evaluates key reproductive, adrenal, and thyroid hormones together to reveal patterns that single tests may miss. By analyzing hormone balance through saliva or blood spot panels, clinicians and patients gain clearer insight into symptoms such as irregular cycles, fatigue, mood changes, fertility concerns, and menopause transitions—supporting more personalized and effective care.

Saliva hormone testing is one of the most accurate and convenient ways to measure bioavailable hormones — the fraction that is actually active in your body's tissues. Unlike standard blood tests, which measure total hormone levels including protein-bound fractions that cells cannot use, saliva testing captures only the free, unbound hormones that drive real physiological effects. This guide explains how saliva testing works, which hormones it measures, why it is clinically superior for monitoring hormone therapy, and how to choose the right test for your health goals.

If you are experiencing infertility issues, understanding which hormones to test — and why — is the essential first step. Dr. Alison McAllister of ZRT Laboratory explains the full fertility hormone profile: from LH and FSH as indicators of ovarian reserve, to estradiol, progesterone and testosterone for ovulation health, adrenal hormones cortisol and DHEA-S, thyroid markers including TPO antibodies, and the often-overlooked role of vitamin D in fertility and PCOS.

As the days shorten and sunlight fades, four key hormonal systems come under pressure: vitamin D, serotonin, cortisol and melatonin. For those susceptible to Seasonal Affective Disorder (SAD), the disruption of these interconnected rhythms can trigger depression, fatigue, poor sleep and low mood. This article explains the science behind the SAD hormone pattern — and what you can do to support your body through the darker months.

Over 25 million women enter menopause each year and face decisions about hormone replacement therapy. But HRT dosing is far from standardised — and the testing method used makes all the difference. This article explores why doses vary so widely and how saliva, blood spot and urine testing can help optimise outcomes.
