Longevity & Healthy Aging

Measures 1,25-dihydroxyvitamin D (calcitriol), the active hormonal form of vitamin D produced by the kidneys. Not a routine vitamin D screening test; used to investigate calcium metabolism disorders, chronic kidney disease, and conditions like sarcoidosis.

Analyses methylation patterns on your blood cells using validated epigenetic clock algorithms. Unlike a genetic test, your biological age result is not fixed. It reflects how you've been living and can shift between retests as your lifestyle, sleep, stress and health change.

Full lipid panel measuring total cholesterol, HDL, LDL, triglycerides, and the total cholesterol/HDL ratio. Used for cardiovascular risk assessment. Requires a 10 to 12 hour fast.

Saliva-based DNA test covering health risk variants, carrier status for inherited conditions, and pharmacogenomics. At-home collection with results delivered online.

Measures serum cortisol to assess adrenal function and stress hormone output. Used to investigate persistent fatigue, unexplained weight changes, and suspected adrenal disorders. Collection before 10am required.

Measures reduced glutathione (GSH) and oxidised glutathione (GSSG) from a finger-prick blood spot. The GSH:GSSG ratio reflects how well your body is managing oxidative stress. Relevant for people investigating persistent fatigue, slow recovery, or high environmental exposures.

Measures a single fasted serum growth hormone level to screen for GH deficiency or excess and assess pituitary function. Because GH is released in pulses, a single result is a screening baseline; formal diagnosis typically requires stimulation or suppression testing.

Measures homocysteine, an amino acid that rises when folate, B12, and B6 metabolism is impaired. Elevated levels are associated with increased cardiovascular and neurological risk. Used to investigate B-vitamin deficiency and assess methylation function. Fasting preferred.

At-home cheek swab DNA test screening genetic variants linked to lifespan and healthy ageing. Covers FOXO3, APOE, and related pathway genes involved in oxidative stress, lipid metabolism, DNA repair, and methylation.

The Magnesium Blood Test measures magnesium, a mineral essential for energy production, nerve function, and healthy muscles and bones. Low magnesium may be linked to cramps, fatigue, or irregular heartbeat, while healthy levels support strong muscles, steady energy, and heart health.

The NAD+ Dried Blood Spot Test measures nicotinamide adenine dinucleotide (NAD+) in whole blood from a finger-prick sample collected at home. NAD+ is a coenzyme involved in cellular energy production and DNA repair that declines with age.

The NAD+ Index measures NAD+, NADH, NADP+, NADPH, Nicotinamide (NAM), Nicotinic Acid (NA) and key metabolic ratios from a finger-prick blood spot collected at home.

NutriSTAT looks at how your body is actually working, not just whether your numbers sit inside a reference range. One at-home collection kit covers metabolic function, thyroid markers, cardiovascular risk factors, hormones, essential minerals, toxic metals, fatty acids, amino acids, and organic acids.

Measures magnesium inside red blood cells for a more accurate picture of tissue-level stores than serum testing. Preferred when deficiency symptoms persist despite a normal serum result. Available at Healius pathology centres.

Measures testosterone using liquid chromatography-mass spectrometry (LCMS), a method that physically separates testosterone from interfering substances before measuring it. More precise than standard immunoassay testing. Available at Healius pathology locations only.

Measures total testosterone in blood, the primary androgen hormone in both men and women. Testosterone influences energy, muscle mass, bone density, mood and sexual function.

Measures 100 health biomarkers in a single blood draw, covering hormones, vitamins and minerals, organ function, inflammation, immune health, iron and metabolic markers. Available in separate male and female panels.
