Specialized test targeting specific health concerns or advanced biomarkers.
Essential fatty acid testing measures the levels of omega-3, omega-6, and other fatty acids in your blood. The omega-3 index — measuring EPA and DHA as a percentage of total red blood cell fatty acids — is an emerging cardiovascular risk marker. An index below 4% is associated with higher risk of sudden cardiac death, while above 8% is considered optimal. The balance between omega-6 and omega-3 fatty acids also matters: a high omega-6 to omega-3 ratio promotes inflammation, while a lower ratio is anti-inflammatory. Most people in Western diets have ratios of 15:1 or higher, versus the recommended 4:1 or lower. Testing helps personalize supplementation and dietary choices.
