The High-Sensitivity CRP (hs-CRP) Blood Test measures very small amounts of C-reactive protein, a marker of inflammation in the body. Higher hs-CRP levels can be linked to a greater risk of heart disease, stroke, or chronic inflammation, while lower levels suggest healthier cardiovascular and immune function.

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 Homocysteine Blood Test measures levels of homocysteine, an amino acid in the blood. High levels can be linked to heart disease, stroke, and vitamin deficiencies (B6, B12, or folate), while healthy levels support circulation, metabolism, and brain health.

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.

The Iodine Random Urine Test measures how much iodine is in your urine. Iodine is essential for making thyroid hormones, which control metabolism, energy, and growth. This test may help check if you’re getting enough iodine from your diet or if thyroid-related symptoms could be linked to low or high iodine levels.

The Iron Studies Blood Test (including ferritin) measures iron levels and how well your body stores and uses iron. Low iron may be linked to anaemia, fatigue, or poor concentration, while high levels may point to iron overload or inflammation.

The Lipase Blood Test measures lipase, an enzyme that helps your body break down fats during digestion. High lipase levels may be linked to pancreatitis or other digestive problems, while normal levels show your pancreas is working as it should.

The Lipoprotein(a) Blood Test measures a type of cholesterol particle that is mostly determined by your genes. High Lp(a) levels may be linked to an increased risk of heart disease and stroke, even when standard cholesterol results look normal.

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.

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.

Work with metals or have a nickel allergy? Nickel is a trace element found in the environment, but too much can cause allergic reactions or health issues. This test may help check for workplace exposure, overexposure from jewellery or food, or explore whether nickel sensitivity is linked to your symptoms.

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 Phosphate Blood Test measures phosphate, an essential mineral and electrolyte that supports strong bones, energy production, and muscle and nerve function. Abnormal levels may suggest problems with kidneys, hormones, or nutrition.

The Potassium Blood Test measures potassium, a mineral and electrolyte that helps control muscle movement, nerve signals, and heart rhythm. Abnormal levels may suggest kidney problems, hormone imbalances, or issues with diet and medications.

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 Red Blood Cell Copper Blood Test measures copper stored inside red blood cells, giving a clearer view of long-term copper status than a standard blood test. Copper is essential for energy, immunity, and red blood cell production. Low levels may cause fatigue, anaemia, or weak immunity, while high levels may indicate toxicity or over-supplementation.

This test is only available at Healius and 4Cyte collection centres.

The Red Blood Cell Magnesium Blood Test measures magnesium stored inside red blood cells, giving a more accurate picture of long-term magnesium status than a standard blood test. Magnesium is vital for energy, muscle function, heart rhythm, and nerve health. Low levels may cause cramps, fatigue, or heart problems.

This test is only available at Healius and 4Cyte collection centres.

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.

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.
