Hormones

Measures gastrin, the stomach hormone that controls acid production. Used to investigate Zollinger-Ellison syndrome, H. pylori effects on gastric function, and long-term proton pump inhibitor use. Fasting required before collection.

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.

Calculates the HOMA-IR score from fasting glucose and fasting insulin to estimate insulin resistance. A higher score suggests the pancreas is working harder than expected to maintain normal blood sugar. Used to assess metabolic syndrome risk, PCOS, and type 2 diabetes risk factors. Overnight fast required.

Measures 17-hydroxyprogesterone (17-OHP), a steroid in the cortisol synthesis pathway. Elevated levels indicate an adrenal enzyme deficiency, most commonly 21-hydroxylase deficiency (congenital adrenal hyperplasia). Used to screen for CAH and investigate unexplained androgen excess.

Measures IGF-1, a stable downstream marker of growth hormone produced by the liver. Used to investigate growth disorders in children, assess growth hormone deficiency or excess in adults, and monitor growth hormone therapy.

At-home urine test measuring metabolites of serotonin, dopamine, norepinephrine, GABA, and glutamate. Reflects peripheral neurotransmitter production patterns. Intended for practitioner review alongside clinical assessment.

Measures leptin, the hormone produced by fat cells that regulates appetite and energy balance. Used to assess satiety signalling and investigate possible leptin resistance. Requires fasting before collection.

Measures lithium concentration 12 hours after the last dose. Used for routine therapeutic monitoring of lithium therapy to confirm levels remain in the effective range and to prevent toxicity.

Measures luteinizing hormone (LH), which triggers ovulation in women and stimulates testosterone production in men. Used to investigate fertility, menstrual irregularity, PCOS, and menopause. Cycle timing matters for accurate interpretation.

At-home morning saliva test measuring testosterone, DHEA-S, oestrone, and oestradiol. Captures bioavailable (free) hormone levels to assess male hormone balance affecting energy, libido, muscle maintenance, and mood.

At-home morning saliva test measuring testosterone, DHEA-S, oestrone, oestradiol, and androstenedione with calculated hormone ratios. Adds production capacity and conversion efficiency data beyond the basic male hormone panel.

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.

The Oestradiol (E2) Blood Test measures the most potent form of oestrogen in your blood. In women it plays a central role in the menstrual cycle, fertility, and bone density; in men it is produced in small amounts from testosterone and supports bone health and libido. Used to investigate fertility, irregular periods, menopause, and hormonal symptoms.

The Oestradiol LCMS Blood Test uses liquid chromatography tandem mass spectrometry (LC-MS/MS) to measure oestradiol with greater accuracy than standard immunoassay, particularly at low concentrations. It is the preferred method for men, post-menopausal women, children, and anyone monitoring low-dose hormone therapy.  (Only Available At Healius Locations)

The Parathyroid Hormone (PTH) Blood Test measures the hormone produced by four small glands behind your thyroid that regulates calcium levels in your blood and bones. PTH is commonly tested alongside calcium and Vitamin D to investigate bone density concerns, abnormal calcium levels, or suspected parathyroid dysfunction.

The Progesterone Blood Test measures serum progesterone, the hormone produced after ovulation that maintains the uterine lining and supports early pregnancy. Tested at mid-luteal phase (typically day 21 of a 28-day cycle), a result above the reference threshold confirms that ovulation has occurred.

The Prolactin Blood Test measures this pituitary hormone in your blood. Outside of pregnancy and breastfeeding, elevated prolactin can disrupt ovulation and cause irregular periods, fertility difficulties, or unexpected nipple discharge. A 30-minute rest before collection is required for an accurate result.

The PSA Blood Test measures prostate-specific antigen, a protein produced by the prostate gland. Elevated levels may indicate benign prostate enlargement, inflammation, or prostate cancer, though PSA is prostate-specific rather than cancer-specific. It is a screening tool, and an elevated result means further assessment is warranted rather than a diagnosis.

Measures zinc inside red blood cells, giving a more accurate picture of tissue-level zinc status than a standard serum test. Useful when serum zinc appears normal but symptoms of deficiency persist, or for monitoring zinc status in people with absorption conditions.

The Reverse T3 (rT3) Blood Test measures an inactive form of thyroid hormone produced when the body diverts T4 away from the active T3 pathway. This can occur during physical stress, illness, or calorie restriction, and may contribute to low thyroid symptoms even when standard thyroid tests appear normal.

The SHBG Blood Test measures sex hormone binding globulin, a liver protein that binds to testosterone and oestradiol and controls how much of each hormone is biologically available.

The Sleep Profile Extensive Saliva Test measures melatonin and cortisol at three points across the day and evening from saliva samples collected at home.
