Is Omega-3 Index useful for Allergie?

The Omega-3 Index measures EPA and DHA in red blood cell membranes and is primarily validated for cardiovascular risk assessment. For allergies, the evidence is mixed: some observational and interventional studies suggest anti-inflammatory effects may modestly benefit allergic rhinitis or asthma, but results are inconsistent and effect sizes small. The index is not a standard allergy marker. Consumer tests can provide the value, but using it to guide allergy management lacks strong support. High doses (>3 g/day) may increase bleeding risk. Evidence: mixed. Sources: none directly provided in context.
