Understand Your Immune System & Autoimmunity
Your immune system plays a central role in inflammation, energy, recovery, gut health, allergies and autoimmunity. Whether you're investigating unexplained symptoms, a suspected autoimmune condition, allergies, chronic inflammation or a lingering viral infection, our immune and inflammation tests help you understand what's happening. Read our guide to why immune balance matters more than immune boosting. Order online, no GP referral needed.

Want the most complete picture of your immune and autoimmune health?
If you're looking for a thorough autoimmune blood test or a complete immune system assessment, these comprehensive panels analyse immune activation, regulation, inflammation and allergy pathways - a deep dive when symptoms are unexplained or an autoimmune process is suspected. Discuss results with your GP.
Measure ANA and key autoimmune markers — results to discuss with your GP if autoimmune concerns are relevant.
Measure NK cell count and lymphocyte subsets to assess immune function, viral defence and fertility-related immunity.
Advanced 16-cytokine panel measuring immune signalling molecules linked to chronic inflammation and inflammaging.
Screen 27 vitamins and minerals including zinc, selenium, magnesium, B vitamins and antioxidants in one panel.
Could food sensitivities or allergies be triggering immune symptoms?
Food reactions and allergies can drive inflammation, fatigue, eczema, sinus issues and gut symptoms. Our allergy and food-reaction tests help identify triggers. For food-specific testing, see our dedicated food intolerance testing, and for gut-immune links, our gut health & digestion testing.
Allergies are on the increase, and food allergies in particular are becoming more common. Measure IgE antibodies across 27 common food and environmental allergens. These allergens may be from foods, pollens, house dust, animal hair or moulds.
Measure coeliac antibody markers. Coeliac disease affects approximately 1 in 70 Australians. Discuss results with your GP.
A food intolerance occurs when someone has difficulty digesting a particular food - this can lead to symptoms such as intestinal gas, abdominal pain or diarrhoea. This Food Intolerance Test includes an IgG screen for 96 common foods.
Advanced DNA-based PCR gut test measuring bacteria, pathogens, parasites, viruses and inflammation markers.
Is your immune system overreactive or underperforming?
Your immune system can become overactive (contributing to autoimmune symptoms) or underactive (increasing infection risk). These tests assess immune regulation and genetic autoimmune susceptibility. Discuss results with your GP.
Measure NK cell count and lymphocyte subsets to assess immune function, viral defence and fertility-related immunity.
Measure HLA-B27 — a genetic marker relevant to certain autoimmune conditions. Discuss results with your GP.
Genetic test for predisposition to coeliac disease, type 1 diabetes, rheumatoid arthritis and autoimmune thyroid.
Measure ANA and key autoimmune markers — results to discuss with your GP if autoimmune concerns are relevant.
Do chronic or reactivated viral infections affect your health?
Viruses such as EBV, CMV, Lyme disease and Ross River can stay dormant and reactivate during stress or illness, contributing to fatigue and ongoing symptoms. These antibody tests help identify current or past infection.
Blood test for EBV antibodies to confirm current or past Epstein-Barr virus infection (mono/glandular fever).
Cytomegalovirus is a common infection with a wide range of symptoms - from no symptoms to fever and fatigue, to severe symptoms involving the eyes, brain, or other internal organs.
Test for Ross River virus antibodies - Australia’s most common mosquito-borne infection causing joint pain and fatigue.
Measure Borrelia burgdorferi antibodies — relevant for those with a history of tick exposure. Discuss results with your GP.
Lyme disease is a tick-borne infection caused by the bacteria Borrelia burgdorferi. The first symptom is usually a characteristic pink or red rash that starts as a small red spot that gradually spreads in a much larger circle.
Is chronic inflammation a hidden factor?
Chronic low-grade inflammation can drive fatigue, joint pain, cardiovascular risk and accelerated ageing. These tests measure inflammatory markers. Read our guide to inflammaging: the slow-burning inflammation that accelerates ageing.
Simple blood test for C-reactive protein (CRP) — a widely used marker of inflammation.
Measure homocysteine levels — a biomarker commonly included in cardiovascular and wellness assessments.
Advanced 16-cytokine panel measuring immune signalling molecules linked to chronic inflammation and inflammaging.
