Immune System Health

Measures IgA antibodies against tissue transglutaminase, the recommended first-line blood test for coeliac disease screening. Also used to monitor dietary adherence in people already diagnosed with coeliac disease on a gluten-free diet.

Screens for antinuclear antibodies (ANA), which can indicate an autoimmune process targeting the body's own cell nuclei. The standard first-line test when systemic autoimmune conditions such as lupus, Sjogren's syndrome or scleroderma are suspected.

Measures arsenic in the blood, reflecting recent exposure from dietary, occupational or environmental sources. Most relevant for people with occupational arsenic contact, those using bore or well water in affected areas, and high consumers of rice or seafood.

Measures beryllium in the blood to assess occupational exposure. Used in workplace health surveillance for people in aerospace, electronics, nuclear, dental alloy and metal manufacturing where beryllium dust or fumes are a hazard. Reflects recent exposure only; a BeLPT test assesses immune sensitisation separately.

Measures C-reactive protein (CRP), a protein released by the liver in response to inflammation. Levels rise with infection, autoimmune flares, injury and tissue damage. A broad inflammatory marker used across a wide range of clinical investigations.

Measures serum copper to assess iron metabolism, connective tissue health, and neurological function. Often ordered alongside zinc, as the two minerals compete for absorption.

Measures serum cortisol to assess adrenal function and stress hormone output. Used to investigate persistent fatigue, unexplained weight changes, and suspected adrenal disorders. Collection before 10am required.

Measures erythrocyte sedimentation rate (ESR), a non-specific inflammation marker. Used to screen for autoimmune conditions, chronic infections, and inflammatory diseases, and to monitor disease activity.

Australia's most commonly ordered blood test. Measures red blood cells, white blood cells, platelets, haemoglobin, haematocrit, and cell indices to screen for anaemia, infection, immune disorders, and haematological conditions. No fasting required.

Detects antibodies against stomach parietal cells, which produce stomach acid and intrinsic factor needed for B12 absorption. Used to investigate pernicious anaemia, autoimmune gastritis, and unexplained B12 deficiency.

Measures total globulin, a group of blood proteins including immunoglobulins, transport proteins, and clotting factors. Used to investigate chronic infections, inflammatory conditions, liver disease, and immune function. Often assessed alongside albumin as part of a liver function panel.

Measures gold concentration in blood. Used to monitor gold-based medical treatments and assess occupational exposure in mining, jewellery manufacturing, and electronics production. Gold accumulates in tissues over time, making regular monitoring important.

Checks for Hepatitis A antibodies to assess immunity from past infection or vaccination. Results guide vaccination decisions, particularly before travel to endemic areas or for occupational screening in healthcare and food service.

Measures Hepatitis B markers including HBsAg, Anti-HBs, and Anti-HBc to determine immunity and infection status. Results show whether you are susceptible, immune from vaccination, immune from past infection, or currently infected.

Screens for hepatitis C antibodies indicating past or current HCV exposure. A positive result does not confirm active infection; follow-up HCV RNA testing is needed to determine whether the virus is still present. Often causes no symptoms, making screening important for people with risk factors.

Measures very low levels of C-reactive protein to assess cardiovascular risk from chronic low-grade inflammation, even when cholesterol appears normal. No fasting required.

Measures histamine in whole blood to investigate histamine intolerance, mast cell activation, and conditions where excess histamine accumulation may be driving symptoms such as headaches, flushing, digestive discomfort, and nasal congestion.

Fourth-generation blood test screening for HIV-1/2 antibodies and p24 antigen simultaneously. Can identify HIV from around 2 to 4 weeks after exposure, earlier than older antibody-only tests. Reactive results require confirmatory testing.

At-home blood spot test screening IgG antibody levels to 96 Asian cuisine foods. Covers ingredients that standard Western panels miss, including fermented condiments, specific soy products, seaweeds, and regional vegetables.

At-home blood spot test screening IgG antibody levels to 96 plant-based foods. Covers legumes, grains, nuts, seeds, soy products, and other vegetarian staples that standard Western panels may not include.

Measures IgA, the antibody protecting mucosal surfaces in the gut and respiratory tract. Used to screen for IgA deficiency and validate coeliac antibody testing, as low IgA can cause false-negative coeliac results.

Measures IgD, the rarest major antibody class. Primarily ordered to investigate hyper-IgD syndrome (HIDS/mevalonate kinase deficiency) in the context of recurrent periodic fevers. Rarely used outside specialist settings.

Measures total IgE, the antibody involved in allergic reactions. Elevated levels are associated with asthma, eczema, allergic rhinitis, and parasitic infection. Does not identify specific allergens.
