Hormone Testing & Optimisation Assessment

The Longevity Lab Perth includes a full hormonal assessment within its biomarker panels, covering growth hormone, IGF-1, testosterone (total and free), oestrogen, cortisol, DHEA-S, and thyroid function (TSH, T3, T4). Results are interpreted by a clinician against optimal longevity ranges, enabling targeted hormonal optimisation strategies for energy, body composition, mood, and healthy ageing in Perth and across Western Australia.

Hormonal status is one of the six core assessment domains at The Longevity Lab in Perth CBD, reflecting the central role that hormone balance plays in biological ageing, body composition, energy, cognitive function, libido, and overall wellbeing. Rather than a narrow check of TSH alone — the standard in most GP-ordered thyroid assessments — the clinic tests a full thyroid panel including TSH, free T3 (the active thyroid hormone), and free T4 (the storage form), providing a complete picture of thyroid conversion and function that often reveals subclinical hypothyroidism missed by TSH alone. Reproductive hormones assessed include total testosterone, free testosterone (the biologically active fraction), sex hormone-binding globulin (SHBG), and oestradiol — important for both male and female patients, as testosterone declines in men from the late 30s onward and oestrogen fluctuates substantially in women during perimenopause and menopause. The adrenal hormone panel covers cortisol and DHEA-S, reflecting the HPA axis stress response and adrenal reserve — elevated chronic cortisol is strongly associated with metabolic dysfunction, immune suppression, and accelerated ageing, while declining DHEA-S is one of the most reliable biomarkers of biological age. Growth hormone and IGF-1 levels are assessed as markers of anabolic capacity, tissue repair, and body composition regulation — markers that predictably decline with age and can be meaningfully supported through targeted lifestyle, nutrition, and in some cases, supervised therapeutic protocols. At The Longevity Lab Perth, all hormonal test results are reviewed by a clinician who maps findings against optimal longevity-targeted reference ranges and provides personalised recommendations, making this a genuinely actionable hormonal health assessment rather than a pass/fail screening tool. Telehealth consultations are available for clients outside Perth or Western Australia who want to engage with the programme remotely.
