Understand Your Immune System & Autoimmunity

Your immune system plays a central role in inflammation, energy, recovery, gut health, allergies and long-term disease risk. Whether you're dealing with recurring infections, unexplained symptoms, autoimmune concerns, or allergic reactions, our immune system tests help uncover what's driving your symptoms. From allergy testing and autoimmune blood tests to cytokine panels, viral screening and inflammation markers like the CRP blood test, these assessments give you a clear, science-based understanding of your immune health.

Want the most complete picture of your immune and autoimmune health?

Our comprehensive immune panels analyse immune activation, regulation, inflammation, allergy pathways and autoimmune markers. These tests help identify whether your symptoms are driven by overactivity, underactivity or hidden immune dysregulation.

Autoimmune Test
5 tests included
$120 AUD
Autoimmune diseases affect around 5% of people and are one of the most important health issues in Australia and New Zealand. There are over 80 different autoimmune diseases ranging from common to very rare.
View Test
Natural Killer Cells (Lymphocyte Subsets) Test
9 tests included
$149 AUD
Natural Killer cells are a type of white blood cell that play a key role in the recognition and elimination of virally infected cells and tumour cells. Abnormal natural killer cell activity has been associated with infertility, autoimmune disorders and chronic infections.

Test Kit
Cytokine Inflammation Test
16 tests included
$449 AUD
Cytokines are small immune signalling proteins that coordinate inflammation, cell repair and immune defence. When balanced, they help the body respond appropriately to infection or injury. But when dysregulated, cytokines can drive chronic, low-grade inflammation, known as inflammaging, which is linked to accelerated ageing and many long-term health conditions.

Nutrition Micronutrient Test
27 tests included
$399 AUD
Micronutrients are vitamins and minerals needed by the body in very small amounts. Micronutrients are vital to healthy development and disease prevention, and deficiencies may also lead to reductions in energy level, mental clarity and overall capacity.

Is your immune system overreactive or underperforming?

Your immune system can become overactive, contributing to autoimmune symptoms, or underactive, increasing susceptibility to infections and chronic inflammation. Autoimmune markers like HLA-B27 and HLA-DQ/DR haplotypes, alongside NK cell, cytokine and broader autoimmune testing, can reveal immune dysregulation and genetic risk factors that may be driving your symptoms.

HLA-B27 Blood Test
1 test included
$69 AUD
This test is used to determine whether you have human leukocyte antigen B27 (HLA-B27) on the surface of your cells, and to help assess the likelihood that you have an autoimmune disorder associated with the presence of HLA-B27.

Test Kit
HLA DQ/DR Haplotypes
3 tests included
$330 AUD
Understand your genetic predisposition to autoimmune conditions and gluten sensitivity with the HLA DQ/DR Haplotypes Test. This advanced genetic test provides insights into your immune function, helping you identify potential triggers for conditions like coeliac disease, type 1 diabetes, rheumatoid arthritis, and autoimmune thyroid disorders.

Do chronic or reactivated viral infections affect your health?

Viruses such as EBV, CMV, Lyme disease and Ross River can stay dormant in the body and reactivate during periods of stress, leading to fatigue, joint pain, immune dysfunction and ongoing inflammation. Viral testing identifies past infection, recent exposure or reactivation so you can better understand whether persistent symptoms are linked to immune-viral interactions.

Epstein-Barr Virus Test
3 tests included
$59 AUD
It can be difficult to diagnose EBV because its symptoms so closely resemble a range of other illnesses. However, a blood test can confirm the presence of EBV antibodies in the system, or whether someone has had a recent or past infection.

Cytomegalovirus (CMV) Test
3 tests included
$59 AUD
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.

Lyme Disease Test
1 test included
$59 AUD
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.

Lyme Western Blot Test
1 test included

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.

Ross River Virus Test
1 test included
$79 AUD
Ross River virus (RRV) is a virus transmitted to humans primarily through the bite of infected mosquitoes. It is the most common mosquito-borne disease in Australia.

Could food sensitivities or gut issues be triggering immune symptoms?

Food reactions, allergies and gut-immune interactions can drive inflammation, digestive symptoms, fatigue, eczema, sinus issues and autoimmune flare-ups. Our allergy and food sensitivity panel, including allergy blood tests, food allergy testing and gluten testing, can help identify triggers and uncover underlying immune drivers.

Coeliac Test
2 tests included
$69 AUD
Coeliac disease is an autoimmune disorder triggered by gluten that can cause severe digestive problems. It affects 1 in 70 Australians who are mostly diagnosed in adulthood.
View Test
Coeliac HLA Typing Test
1 test included
$169 AUD
Patients with coeliac disease almost always have specific variants of HLA-DQ2 and HLA-DQ8. These variants are necessary, but not sufficient, for the disease to occur.

ImmunoCAP Allergy Test
120 tests included
$550 AUD
The Immunocap ISAC test is an advanced diagnostic tool used to identify and measure the levels of specific IgE antibodies in the blood. IgE antibodies are produced by the immune system in response to exposure to allergens such as pollen, dust mites, and animal dander.

Food Intolerance Blood Test
96 tests included
$390 AUD
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 Check includes a screen for 96 foods.

Allergy Test
27 tests included
$109 AUD
Allergies are on the increase, and food allergies in particular are becoming more common. Allergies are caused by an overreaction of the body’s immune system to certain innocuous molecules from the outside world. These allergens may be from foods, pollens, house dust, animal hair or moulds.

Is inflammation quietly impacting your long-term health?

Chronic low-grade inflammation is linked to autoimmunity, cardiovascular disease, fatigue, weight gain and accelerated ageing. Our inflammation panels, including CRP, cytokines and homocysteine, help detect silent inflammation early and clarify what elevated CRP levels mean for immune activity.

CRP Test
1 test included
$29 AUD
Chronic inflammation often develops silently - long before symptoms appear. Over time, it can contribute to fatigue, joint pain, heart disease, and metabolic issues. Our Inflammation blood test is designed to detect subtle, early signs of inflammation so you can take proactive steps toward better long-term health.

Homocysteine Blood Test
1 test included
$49 AUD
The importance of homocysteine as a marker for health and wellbeing has recently become evident with elevated levels now recognised as a risk factor for cardiovascular disease, osteoporosis and Alzheimer’s.
