Comprehensive blood test analyzing 24 fatty acids, including Omega-3 Index, ratios, and Trans Fat Index.
This test measures all fatty acids in the blood, reporting levels of 24 fatty acids, including the Omega-3 Index, various ratios, and the Trans Fat Index. It provides detailed information about the types and amounts of fatty acids present, helping assess dietary fat intake and its impact on health. Key health aspects covered include cardiovascular health, inflammation, and the balance of essential fatty acids. The test helps identify potential risks associated with heart disease and stroke. Results can guide dietary changes to optimize fatty acid balance.

Who Is This For?
Anyone taking fish oil or omega-3 supplements who wants to verify they're achieving optimal levels. People interested in cardiovascular risk reduction beyond standard lipid panels. Those following anti-inflammatory diets who want to measure their omega-6 to omega-3 ratio. Athletes interested in recovery and inflammation management. Vegetarians and vegans who may not get enough EPA and DHA.
What's Included
Preparation Required
No fasting required. Continue your normal diet and supplements — the test measures your steady-state levels. Some labs use a finger-prick blood spot test that can be done at home.
Biomarkers Tested
4Measures the percentage of EPA and DHA (omega-3 fatty acids) in red blood cell membranes. An index above 8% is associated with the lowest cardiovascular risk, while below 4% indicates high risk. Reflects long-term omega-3 intake over 2–3 months.
The balance between pro-inflammatory omega-6 and anti-inflammatory omega-3 fatty acids. A lower ratio (ideally below 4:1) is associated with reduced inflammation and lower cardiovascular risk. Modern Western diets often have ratios of 15:1 or higher.
Shows the balance of arachidonic acid (AA, omega-6) and eicosapentaenoic acid (EPA, omega-3); omega-6 may promote inflammation, while omega-3 is anti-inflammatory.
Level of trans fatty acids in the blood, reflecting dietary intake.
