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. For a broader perspective on immune function, read our article on why immune balance matters more than immune boosting.

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.
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.
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.
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.
Chronic low-grade inflammation can drive fatigue, joint pain, cardiovascular risk and accelerated ageing — often without obvious symptoms. CRP, cytokine panels and homocysteine testing can detect this invisible inflammation. Read our deep dive into inflammaging: the slow-burning inflammation that accelerates ageing to understand why managing inflammation is one of the most important steps you can take for long-term health.
