Concerned 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.

The CRP Blood Test measures C-reactive protein, which rises in the blood with inflammation. High CRP levels can suggest infection, injury, or chronic inflammatory conditions, while lower levels are linked with healthier immune and heart function.

The 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.

The Full Blood Count (FBC) Blood Test measures your blood's red cells, white cells, and platelets. 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.

Work 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.

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 Immunoglobulin A (IgA) test measures antibodies that protect mucous membranes in the respiratory and digestive tracts. Abnormal IgA levels can indicate immune deficiencies, chronic infections, or autoimmune conditions such as coeliac disease.

The Immunoglobulin D (IgD) test measures a rare type of antibody involved in initiating immune responses. Abnormal IgD levels can be linked to certain immune disorders, chronic infections, and some inflammatory or autoimmune conditions.

The Immunoglobulin E (IgE) test measures the amount of IgE antibodies in the blood. IgE plays a key role in allergic reactions, triggering the release of histamine and other chemicals when the body encounters allergens such as pollen, dust, or certain foods. Elevated IgE levels can indicate allergic conditions like hay fever, asthma, or eczema, and may also occur in some parasitic infections. This test helps identify potential allergic triggers and supports the diagnosis of allergy-related disorders.

The Immunoglobulin G (IgG) test measures the most common type of antibody in the blood. IgG plays a key role in defending against bacterial and viral infections and provides long-term immunity after exposure or vaccination. Abnormal IgG levels can indicate immune deficiencies, chronic infections, autoimmune conditions, or certain allergies. This test is often used to assess immune system health, investigate recurrent infections, and monitor immune-related disorders.

Investigate immune-mediated inflammation with our Immunoglobulin G4 (IgG4) test. This specialised analysis measures IgG4 levels to diagnose IgG4-related disease, assess chronic inflammatory conditions, and evaluate immune tolerance mechanisms affecting multiple organ systems.

Detect early immune responses with our Immunoglobulin M (IgM) Test. This important analysis measures IgM levels to identify recent infections, assess primary immune function, and evaluate your body's first-line antibody response to pathogens and immune challenges.

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.

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.

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 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 Rheumatoid Factor (RF) Blood 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.
