Immune System Health
Immune system health refers to the body's capacity to defend against infections, illnesses, and harmful pathogens, keeping you healthy and functioning optimally. The immune system is a complex network of cells, tissues, and organs that work together to recognise and neutralise threats like bacteria, viruses, and other foreign substances. A well-functioning immune system not only fights off infections but also helps to identify and remove damaged or abnormal cells, contributing to overall health and wellbeing. Key factors influencing immune system health include a balanced diet rich in vitamins and minerals (such as vitamin C, zinc, and iron), regular physical activity, adequate sleep, stress management, and minimising exposure to environmental toxins. Supporting immune health involves maintaining a healthy lifestyle, with nutrient-rich foods, regular exercise, and good hygiene practices all playing a crucial role in keeping your body’s defences strong and ready to respond to potential threats.

Vitamins & MineralsCopperThe Copper Blood Test measures copper, a mineral essential for making red blood cells, supporting energy production, and keeping the immune and nervous systems healthy. Low copper may be linked to anaemia, fatigue, or weak immunity, while high levels may suggest overload or exposure from supplements, water, or the environment.
-
InflammationC-Reactive Protein (CRP)The CRP Test measures C-reactive protein, a substance that rises in the blood when there is inflammation. High CRP levels can suggest infection, injury, or chronic inflammatory conditions, while lower levels are linked with healthier immune and heart function.
-
InflammationHighly Sensitive CRP (hs-CRP)The High-Sensitivity CRP (hs-CRP) 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.

HormoneCortisolUnderstand your body's stress response with our Cortisol Blood Test. Often called the 'stress hormone', cortisol plays a crucial role in energy regulation, immune function, and how your body responds to daily challenges. This test helps identify if stress, fatigue, or mood issues might be linked to cortisol imbalances.
-
Blood Deficiency & AnemiaFull Blood Count (FBC)The Full Blood Count (FBC) Test measures red cells, white cells, and platelets in your blood. It may help check for anaemia, infection, immune problems, or overall health changes, and is one of the most commonly requested routine blood tests. This test also includes ESR.
-
Vitamins & MineralsActive Vitamin D (1,25 Dihydroxy) TestThe Active Vitamin D Test, also called the Vitamin D (1,25 Dihydroxy) or calcitriol test, measures the active form of vitamin D that your body uses. This test may help check calcium balance, bone strength, muscle health, and immune function, especially when standard vitamin D tests don’t give the full picture.
-
Heavy Metals & ToxicologyGoldWork with gold or exposed through treatment? The Gold Blood Test measures how much gold is in the body. While gold is used in jewellery and industry, high levels usually come from medical treatments or workplace exposure. This test may help check for overexposure and monitor possible effects on the kidneys or immune system.
-
Heavy Metals & ToxicologyArsenicConcerned about water, food, or workplace exposure? Arsenic is a toxic metal that can build up in the body and affect the skin, nerves, kidneys, and immune system. This test may help check for overexposure and monitor possible health risks.
-
Heavy Metals & ToxicologyNickelWork 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.
-
Vitamins & MineralsRed Blood Cell Copper (RBC Copper)The Red Blood Cell Copper 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.
-
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.
-
Infectious Disease ScreeningRoss River Virus Serology (RRV)The Ross River Virus (RRV) Serology Test checks for antibodies your body makes after infection with Ross River virus, which is spread by mosquitoes in Australia. This test may help confirm exposure if you have symptoms such as joint pain, fever, tiredness, or rash.
-
ThyroidThyroglobulinThe Thyroglobulin Test measures a protein made by the thyroid gland. After thyroid surgery or treatment for thyroid cancer, this test may help check for recurrence. It can also be used alongside antibody tests to assess thyroid function and possible autoimmune activity.
-
Liver HealthTotal ProteinThe Total Protein Test measures the amount of protein in your blood, including albumin and globulins. Proteins are important for building and repairing tissues, fighting infections, and maintaining fluid balance. Abnormal levels can signal liver or kidney problems, nutritional issues, or immune disorders.
-
Vitamins & MineralsVitamin AEvaluate vision and immune health with our comprehensive Vitamin A test. This important analysis measures vitamin A levels to assess visual function, evaluate immune system status, investigate skin health, and guide supplementation for optimal health and development.
-
Vitamins & MineralsVitamin CThe Vitamin C Blood Test measures levels of this essential vitamin, which supports immune defence, helps the body heal, and protects cells from damage. Low vitamin C can cause fatigue, slow wound healing, and in severe cases, scurvy. Adequate levels are important for energy, skin health, and overall wellbeing.
-
Vitamins & MineralsVitamin D (25-OH)Boost your health from the inside out with our comprehensive Vitamin D Blood Test. Often called the 'sunshine vitamin', vitamin D is crucial for bone strength, immune function, mood regulation, and overall wellbeing - yet deficiency is surprisingly common, especially in Australia's climate extremes.
-
Vitamins & MineralsVitamin EThe Vitamin E Blood Test measures levels of this key antioxidant that helps protect cells from damage. Adequate vitamin E supports immunity, skin health, and circulation, while low levels may increase the risk of oxidative stress and related health issues.
-
Vitamins & MineralsZincThe Zinc Blood Test measures levels of zinc, an essential mineral needed for immune function, wound healing, hormone balance, and metabolism. Low zinc can lead to poor immunity, skin problems, and fertility issues, while high levels may indicate excessive supplementation or exposure.
-
AutoimmuneRheumatoid Factor (RF)The Rheumatoid Factor (RF) test checks for an antibody that can be present when the immune system attacks healthy tissues. Higher levels are often linked to rheumatoid arthritis and other autoimmune diseases that cause joint pain, swelling, and stiffness.
-
Fertility & PregnancyCA-125 Blood Test (Ovarian Cancer Marker)The CA-125 Blood Test measures a protein that can rise in the blood with ovarian cancer and certain non-cancer conditions. This test may help monitor ovarian health, especially if you have symptoms, known risk factors, or are being followed up after treatment. It is usually used alongside other checks rather than as a stand-alone cancer test.
