A chronic inflammation test measures the proteins your immune system uses to signal, and a 250-protein immune profile reads hundreds of them at once instead of a single marker. In people living with long COVID, ME/CFS, POTS, MCAS, or fibromyalgia, this kind of profiling maps immune signaling in far more detail than routine labs, benchmarks each protein against a healthy reference, and tracks change over time. It measures and informs. It does not diagnose.
Key takeaways
- Chronic inflammation is persistent, low-grade immune signaling that standard tests like CRP often miss because they read only one broad marker.
- A 250-protein immune profile covers cytokines, chemokines, interferons, and receptors together, giving a wider view of what your immune system is doing.
- Research links altered immune signaling to conditions including long COVID and ME/CFS, though no single blood biomarker diagnoses these illnesses today.
- For ME/CFS, fibromyalgia, and MCAS there is no validated diagnostic blood test. Inflammation profiling is a research and monitoring tool, not a diagnosis.
- Benchmarking against a healthy reference and retesting over time turns "normal" into "typical or not," and shows whether anything is changing.
What is chronic inflammation?
Acute inflammation is the fast, visible response to injury or infection: redness, swelling, fever, then resolution. Chronic inflammation is different. It is a low-grade, ongoing state where immune signaling stays switched on longer than it should, often without obvious outward signs. You may feel it as fatigue, pain, or brain fog while your standard bloodwork reads unremarkable.
The reason routine labs can miss it is scope. A basic inflammation order usually returns CRP, an acute-phase protein made by the liver, and sometimes ESR. Both are broad. They can be normal even when specific cytokines and chemokines are shifted, because they average over a system that speaks in dozens of distinct signals.
How does chronic inflammation relate to chronic illness?
Many post-viral and complex chronic conditions share a common thread of dysregulated immune signaling, which is why chronic inflammation and disease come up together so often. Researchers studying long COVID have found that immune profiling can distinguish people with the condition from those without it, using patterns across many proteins rather than one marker (Klein et al., Nature 2023). A large study also found that common lab tests are not reliable for diagnosing long COVID, which underlines why breadth matters (University of Colorado Anschutz).
This is association, not causation, and it is not a diagnostic test. A profile that looks unusual does not name a disease, and a profile that looks typical does not rule one out. What a broad immune profile offers is context: a detailed reading of your inflammatory signaling that you and your doctor can interpret alongside your symptoms and history.
What does a chronic inflammation test with a 250-protein immune profile reveal?
A 250-plex inflammation panel reports proteins across several families of immune signaling. Each is measured as an absolute concentration and compared to a healthy reference range:
- Cytokines such as IL-6 and TNF, core drivers of the inflammatory response.
- Chemokines such as CXCL10 (IP-10) and CCL2 (MCP-1), which recruit immune cells and rise with interferon activity.
- Interferons such as IFN-gamma and the type I interferons, central to the antiviral response.
- Receptors and regulators such as TNFR1, TNFR2, and IL-6R, which shape how strongly a signal is felt.
- Broader inflammation markers such as GDF15, a stress-associated protein, and CRP for continuity with routine labs.
Seeing these together is the point. One elevated cytokine in isolation says little. A pattern across cytokines, chemokines, and interferons, each benchmarked and tracked, gives a fuller map of immune activity than any single number can.
What are common chronic inflammation symptoms?
The chronic inflammation symptoms people describe most are fatigue that rest does not fix, widespread or migrating pain, brain fog, unrefreshing sleep, and worsening after exertion. These overlap heavily across long COVID, ME/CFS, POTS, MCAS, and fibromyalgia, which is part of why they are so hard to pin down and why so many people feel dismissed when standard tests come back clean.
Symptoms alone cannot tell you what your immune system is doing. That is the gap objective measurement is meant to help close. A benchmarked profile does not explain how you feel, but it can show whether your inflammatory signaling sits inside typical ranges, which is information worth having when you have been told everything looks fine.
How does this apply to specific conditions?
Long COVID: immune profiling is an active research area, and studies show distinguishing signatures across many proteins. The CDC notes long COVID is diagnosed clinically. For the biology in depth, see the inflammation biology of long COVID.
ME/CFS: there is no validated diagnostic blood biomarker today. Diagnosis is clinical and symptom-based per the CDC. Inflammation profiling is a research and monitoring tool here, not a diagnosis. Our piece on ME/CFS and the immune system covers the science.
POTS and dysautonomia: diagnosis is clinical, made with an active stand or tilt-table test. Inflammation profiling adds context around immune signaling. It does not diagnose POTS.
MCAS: there is no single validated diagnostic blood test. Muno does not measure tryptase or histamine, the classic mast-cell mediators. It adds the broader inflammatory-signaling context around them.
Fibromyalgia: no validated diagnostic blood biomarker exists. Diagnosis is clinical. A benchmarked immune profile is a research and tracking tool, not a test that confirms the condition.
Where Muno Mirror fits
Muno Mirror measures a 250-plex inflammation proteomics panel from a small at-home microsample, reports each protein as an absolute concentration against a healthy reference, and lets you retest every three months to see what moved. It is built for people whose routine labs read "normal" but who want objective data to bring to their own doctor. It measures and benchmarks for research and informational use. It does not diagnose, treat, or cure any condition. See what Muno Mirror measures.
Frequently asked questions
What is the best chronic inflammation test?
Routine care usually starts with CRP or hs-CRP, a single broad marker. A 250-protein immune profile is far more detailed, covering cytokines, chemokines, interferons, and receptors together. Neither diagnoses a disease. Both are interpreted by a clinician alongside your symptoms.
Can a blood test detect chronic inflammation?
A blood test can measure inflammatory proteins and compare them to a healthy reference range, which indicates whether signaling is typical or shifted. It measures inflammation; it does not name the disease behind it. Results are informational and best reviewed with your doctor.
Does chronic inflammation cause chronic illness?
Research links dysregulated immune signaling to several complex chronic conditions, but this is association, not proven causation, and it varies between individuals. A profile cannot establish that inflammation caused a specific illness. It provides context to discuss with a clinician.
Why do my labs look normal if I have chronic inflammation symptoms?
Standard panels read only a few broad markers like CRP, which can be normal even when specific cytokines or chemokines are shifted. A wider profile measures many more signals. Normal on a basic test does not mean nothing is happening across your immune system.
