Hormones

The Gastrin test measures the level of a hormone that triggers your stomach to make acid. Too much gastrin can cause stomach ulcers or signal certain rare tumours, while low levels can affect digestion. This test helps check how well your stomach and digestive system are working.

The Growth Hormone (GH) Blood Test measures a hormone that controls growth, muscle mass, and how your body uses fat and sugar. Abnormal levels can affect muscle strength, energy, and metabolism in adults.

The HOMA-IR Test estimates insulin resistance by using fasting glucose and insulin results. This test may help assess your risk of type 2 diabetes, metabolic syndrome, and related heart or hormone problems.

The IGF-1 Blood Test measures insulin-like growth factor 1, a hormone influenced by growth hormone that plays a role in growth, metabolism, and muscle repair. Abnormal levels may be linked to growth disorders, metabolic problems, or hormone imbalances, while healthy levels support strength, energy, and development.

Evaluate appetite regulation with our comprehensive Leptin Blood Test. This important analysis measures leptin levels to assess appetite control, investigate weight management issues, evaluate metabolic function, and guide treatment for obesity and eating disorders.

Monitor lithium therapy safety with our Lithium Serum Level Blood Test. This essential analysis measures lithium concentrations to ensure therapeutic effectiveness while preventing toxicity in individuals using lithium for mood disorders and mental health conditions.

The Luteinizing Hormone (LH) Blood Test measures a hormone that helps control ovulation in women and testosterone production in men. This test may help check fertility, menstrual cycles, or hormone-related symptoms.

Comprehensive functional health panel measuring metabolic health, thyroid function, cardiovascular markers, hormones, minerals, metals, fatty acids, amino acids, and organic acids. The most extensive nutritional and functional health assessment available.

Wondering about your hormone balance? Oestradiol (E2) Blood Test is the main form of oestrogen and plays a key role in fertility, menstrual cycles, bone strength, and overall hormone health. This test may help assess fertility, menopause status, or hormone-related symptoms in both women and men.

Curious about your hormone balance? Oestradiol (E2) is the main form of oestrogen and plays a key role in fertility, menstrual cycles, bone strength, and overall hormone health. This LCMS test offers highly accurate results and may help assess fertility, menopause status, or hormone-related symptoms in both women and men. For men using testosterone or performance therapies, LCMS testing is especially valuable, as it provides precise oestradiol results even when testosterone levels are high.

Concerned about your calcium levels or bone strength? Parathyroid hormone keeps calcium, phosphate, and vitamin D in balance so your bones, muscles, and nerves work the way they should. This test may help check if your parathyroid glands are doing their job and can be useful if you’re experiencing low bone density, kidney stones, or unexplained muscle weakness.

The Progesterone Test measures levels of progesterone, a hormone important for menstrual cycles, fertility, and maintaining pregnancy. In women, levels change during the cycle and rise after ovulation. This test may help assess fertility, ovulation, or hormone balance, and in pregnancy it may help monitor placenta and fetal health.

This test measures levels of prolactin, a hormone made by the pituitary gland. Prolactin is important for fertility, sexual health, and milk production in women. Abnormal levels may suggest hormone imbalances that affect periods, fertility, or sexual function. In some cases, very high prolactin can be linked to growths in the pituitary gland (usually benign), so this test may help guide whether further checks are needed.

The Prostate Specific Antigen (PSA) Blood Test measures the level of PSA, a protein made by the prostate gland. Higher levels may suggest prostate enlargement, inflammation, or cancer, though they can also rise with age or other prostate conditions. This test may help monitor prostate health and support early detection of problems.

The Red Blood Cell Zinc Test measures zinc stored inside red blood cells, giving a more accurate picture of long-term zinc status than standard blood zinc tests. Adequate zinc supports immunity, hormone balance, metabolism, and healing, while low levels may lead to fatigue, poor immunity, and reproductive issues.

This test is only available at Healius collection centres.

The Reverse T3 (rT3) Test measures a form of thyroid hormone that is inactive. High rT3 levels may happen during stress, illness, or inflammation when the body slows metabolism. This test may help give a broader picture of thyroid and metabolic function alongside a Thyroid Function Tests (TSH, T3, and T4).

The Sex Hormone Binding Globulin (SHBG) Test measures the protein that binds to hormones like testosterone and oestrogen in the blood. SHBG levels affect how much free, active hormone is available, and this test may help assess hormone balance, fertility, and metabolic health.

This saliva test measures both melatonin and cortisol — the two hormones most responsible for your sleep-wake cycle — at multiple points across the day and evening. It provides insights into the hormonal factors that may be contributing to poor sleep, whether that's difficulty falling asleep, staying asleep, or waking unrefreshed.

By tracking extended readings of both hormones, this test gives your practitioner a detailed view of how your body transitions between wakefulness and sleep. It's particularly valuable for shift workers, people with chronic insomnia, or anyone whose sleep hasn't responded to standard approaches.

Want a clear picture of your hormone balance? Testosterone is vital for energy, muscle mass, libido, and overall health in both men and women. This LCMS test gives highly accurate results and may help assess fertility, sexual health, and hormone-related symptoms. For men on testosterone or performance therapies, LCMS testing is especially important, as it provides reliable readings even when testosterone levels are higher than normal.
