Track your Omega-3 status from home — no clinic required.
Omega-3 Index Basic Test
The Omega-3 Index Basic Test provides an accurate measurement of the long-chain omega-3 fatty acids EPA and DHA as a % of total fatty acids in your red blood cells. This index is a well-validated biomarker of heart, brain, and inflammation health, and a strong predictor of long-term wellness.
Your blood sample is collected using a dried blood spot (DBS) card — a fast, minimally invasive finger-prick method you can do from home. Once analyzed, you’ll receive a lab-validated report showing your Omega-3 Index and whether you’re in the optimal range (8–12%).
Whether you’re supplementing with fish oil, adjusting your diet, or simply curious about your baseline, this test gives you clarity on where you stand — and how to improve.
Why Your Omega-3 Index Matters
A low Omega-3 Index (below 4%) is associated with an increased risk of cardiovascular disease, cognitive decline, and chronic inflammation. Research shows that an Omega-3 Index of 8–12% is optimal for heart, brain, joint, and eye health. Unlike short-term blood tests, the Omega-3 Index reflects your long-term omega-3 intake over the past 90–120 days, offering a more stable and reliable picture of your health.
How to Improve Your Omega-3 Index
If your result is below the optimal 8% threshold, increasing your intake of EPA and DHA can help. Options include:
- Eating 2–3 servings/week of fatty fish (salmon, sardines, mackerel)
- Taking a high-quality fish oil or algae-based supplement
- Retesting after 8–12 weeks to track your progress
What Is a Healthy Omega-3 Index
A healthy Omega-3 Index is considered to be between 8% and 12%. Most people consuming a Western diet fall below 6%, which is associated with increased health risk. The optimal range is based on decades of research linking higher Omega-3 Index levels with reduced risk of sudden cardiac death, cognitive decline, and systemic inflammation.
Omega-3 Index vs. Plasma Omega-3
Unlike short-term plasma omega-3 tests, which reflect your last meal, the Omega-3 Index reflects omega-3 content in red blood cell membranes over the past 3–4 months. This makes it a more stable and reliable indicator of long-term omega-3 status.
Backed by Science
The Omega-3 Index is supported by over 200+ peer-reviewed studies and is used by researchers, doctors, and nutrition experts around the world. It is included in longitudinal studies, clinical trials, and personalized nutrition programs to evaluate cardiovascular and cognitive outcomes.

FAQs
What is the Omega-3 Index?
The Omega-3 Index is the percentage of EPA and DHA in your red blood cells. An optimal index (8–12%) is associated with reduced risk of cardiovascular disease, cognitive decline, and systemic inflammation. The Omega-3 Index reflects long-term omega-3 intake over the past 3–4 months.
Do I need to fast?
Avoid eating fish or taking Omega-3 supplements for 12 hours before the test.
What’s included in the Omega-3 Index Test kit?
Your kit includes everything you need to collect and return your sample from home: a dried blood spot (DBS) collection card, lancets, alcohol wipe, gauze pad, bandage, full instructions, and a return envelope. You’ll also receive a secure lab report with your Omega-3 Index results and reference ranges.
How accurate is the Omega-3 Index test from a dried blood spot?
The Omega-3 Index measured from dried blood spot (DBS) samples is highly accurate and validated against whole blood and red blood cell (RBC) measurements used in clinical research. Our lab uses validated methods and external proficiency standards to ensure your results are consistent and clinically reliable, even with just a few drops of blood from a finger prick.
How long until I get results?
Once your sample is received by the lab, your results will be available within 3-5 business days.
Can I use this to track supplement effectiveness?
Yes — retesting after 8–12 weeks of omega-3 supplementation can show whether your index has moved into the optimal range.
Is this test suitable for vegetarians or vegans
Yes this test can be especially helpful for those on plant-based diets to assess whether they’re achieving adequate omega-3 intake from algae oil or ALA-rich foods like flaxseed.
