Measures C-reactive protein, a marker of inflammation in the body. Useful for detecting infection and monitoring inflammatory conditions.

Inflammation and autoimmune marker tests measure your body's immune response and can detect both acute and chronic inflammation. High-sensitivity CRP (hsCRP) is a key marker for systemic inflammation and an independent predictor of cardiovascular risk. ESR (erythrocyte sedimentation rate) indicates general inflammation but is less specific. Autoimmune markers like ANA (antinuclear antibodies), rheumatoid factor, and specific cytokines help identify conditions where the immune system attacks the body's own tissues. Chronic low-grade inflammation is increasingly recognized as a driver of heart disease, diabetes, cancer, and neurodegenerative conditions — making these markers valuable for anyone focused on longevity and disease prevention.

Who Is This For?

Anyone with unexplained joint pain, fatigue, or recurrent symptoms that could indicate autoimmune activity. People with a family history of autoimmune diseases (lupus, rheumatoid arthritis, Hashimoto's). Health-conscious individuals tracking inflammation as part of a longevity protocol. Those recovering from illness or injury who want to monitor their inflammatory response.

What's Included

High-sensitivity C-reactive protein (hsCRP)
Erythrocyte sedimentation rate (ESR)
Additional markers vary by panel (ANA, RF, cytokines)

Preparation Required

No fasting required for most inflammation markers. Avoid intense exercise for 24 hours before testing, as it temporarily elevates CRP and other inflammatory markers. Inform your provider of any acute illness, injury, or infection, as these will cause temporary elevations unrelated to chronic conditions.

Biomarkers Tested

2
hs-CRP (High-Sensitivity C-Reactive Protein) mg/L

A highly sensitive test for low-grade chronic inflammation linked to cardiovascular disease risk. Lower hs-CRP values are associated with better cardiovascular outcomes.

ESR mm/hr

Erythrocyte sedimentation rate — measures how quickly red blood cells settle to the bottom of a test tube. Faster settling indicates more inflammation. ESR is a non-specific marker used to monitor inflammatory conditions like arthritis and vasculitis.
