Hormone & Endocrine
Your endocrine system drives energy, mood, weight, fertility, and performance. These profiles assess hormone balance across the thyroid, adrenal, and reproductive axes to spot subtle dysfunction early and translate results into plain‑English insights with optimal ranges.
Use them to establish a baseline, investigate symptoms (fatigue, mood shifts, weight changes, cycle or sexual function) or monitor treatment. You’ll get prioritised next steps across nutrition, sleep, stress and training, plus a sensible retesting cadence to restore balance and sustain long‑term health.

DiabetesFasting InsulinThe Fasting Insulin Blood Test measures insulin levels after not eating for at least 8 hours. High fasting insulin may be linked to insulin resistance, pre-diabetes, or metabolic syndrome, while healthy levels support balanced blood sugar and energy control.
-
Vitamins & MineralsCalciumThe Calcium Blood Test measures calcium, a mineral vital for strong bones, healthy teeth, nerve signals, and muscle function. Low or high calcium levels may be linked to bone weakness, kidney problems, hormone imbalances, or certain medications.
-
HormoneLuteinizing Hormone (LH)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.
-
DiabetesHOMA-IR (Insulin Resistance) TestThe 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.
-
HormoneOestradiol (E2)Wondering 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 test may help assess fertility, menopause status, or hormone-related symptoms in both women and men.
-
HormoneProgesteroneThe 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 foetal health.
-
Vitamins & MineralsRed Blood Cell Zinc (RBC Zinc)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 and 4Cyte collection centres.
-
ThyroidReverse T3 (rT3)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).
-
HormoneSex Hormone Binding GlobulinThe 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.
-
HormoneGrowth Hormone (GH)The Growth Hormone (GH) test measures a hormone that controls growth, muscle mass, and how your body uses fat and sugar. Abnormal levels can affect height in children, muscle strength, energy, and metabolism in adults.
-
Digestive HealthGastrinThe 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.
-
Vitamins & MineralsLithium Serum LevelMonitor lithium therapy safety with our Lithium Serum Level 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.
-
HormoneTestosteroneAssess your hormonal vitality with our comprehensive Testosterone Blood Test. Whether you're experiencing low energy, reduced muscle mass, or changes in libido, this test measures your total testosterone levels to help identify hormonal imbalances affecting your overall well-being and quality of life.
-
HormoneInsulin-like Growth Factor 1 (IGF-1)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.
-
HormoneParathyroid Hormone (PTH)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.
-
HormoneTestosterone (LCMS)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. (not available in NT)
-
ThyroidThyroxine-Binding Globulin (TBG)Understand your thyroid hormone transport with our TBG Blood Test. This protein carries thyroid hormones through your bloodstream, and measuring its levels helps explain unusual thyroid function test results and guide accurate thyroid health assessment.
-
HormoneOestradiol (LCMS)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.
-
Prostate HealthProstate-Specific Antigen (PSA)The Prostate-Specific Antigen (PSA) 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.
-
HormoneAndrostenedioneThe Androstenedione Blood Test measures a hormone made by the ovaries, testes, and adrenal glands that the body uses to produce oestrogen and testosterone. Abnormal levels may be linked to fertility problems, irregular periods, excess hair growth, or hormone-related conditions, while healthy levels support reproductive and metabolic health.
-
DiabetesC-PeptideThe C-Peptide Blood Test measures how much insulin your body is making by checking C-peptide, a substance released alongside insulin. Low levels can suggest type 1 diabetes or poor insulin production, while higher levels may point to type 2 diabetes, insulin resistance, or pancreatic problems.
-
HormoneProlactinThe Prolactin 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.
