Why this matters
A high AA/EPA ratio indicates a dominance of inflammatory lipid mediators and greater risk of chronic inflammation and cardiovascular disease. Maintaining a balanced ratio supports optimal immune and vascular health.
How this connects to other biomarkers
- AA/EPA Ratio is a key inflammation balance marker — ratios > 10 indicate a pro-inflammatory eicosanoid state, while values 1–3 reflect optimal omega-3 status.
- Elevated AA/EPA with high hs-CRP confirms diet-driven systemic inflammation; combine with the Omega-3 Index for a more complete read.
- Responds rapidly to EPA-rich fish oil supplementation.
