Omega-3 Index Test

The Omega-3 Index is especially valuable for healthy ageing, as omega-3 fats support cardiovascular, cognitive, and joint health in later years.

Doctor's Assessment Included

When is this value abnormal?

Deficiency < 4
Insufficient 4–8
Target met ≥ 8

De Omega-3 Index meet EPA en DHA als percentage van de totale vetzuren in erytrocytenmembranen. Het laboratorium hanteert dezelfde grenzen op uw uitslag: < 4,0 geringe cardioprotectie, 4,0–8,0 matige, > 8,0 goede. De streefwaarde uit de literatuur is 8–11 %; het Nederlandse gemiddelde is 6,06 % (n=1.974), dus onder de streefwaarde. De grenzen gelden alleen voor de gestandaardiseerde meting in erytrocyten — een meting in serum of plasma is niet met deze waarden te vergelijken.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

Omega-3 Index: what this test measures

This test measures EPA and DHA as a percentage of total fatty acids in red blood cell membranes, reflecting omega-3 intake over the previous 2-3 months.

Omega-3 Index: why this value matters

An Omega-3 Index above 8% is generally associated with lower cardiovascular risk. Values below 4% may indicate increased risk. It is a modifiable marker that responds well to dietary changes. Consult your healthcare provider.

Omega-3 Index: when is testing worthwhile?

Testing may be recommended as part of cardiovascular risk assessment, to evaluate omega-3 supplementation effectiveness, or to guide nutritional optimisation.

Omega-3 Index: symptoms of a high or low value

Low Levels

A low Omega-3 Index does not cause direct symptoms but may be associated with increased cardiovascular risk and a more pro-inflammatory state.

High Levels

A high Omega-3 Index is generally favourable and associated with cardiovascular protection. Very high levels are rare and not typically a concern.

Omega-3 Index: what to do about an abnormal value

Male

If Low

Low omega-3 index increases cardiovascular risk. Consider fish oil supplementation or more oily fish.

If High

High omega-3 index is protective for heart health.

Female

If Low

Low omega-3 index increases cardiovascular risk. Consider fish oil supplementation or more oily fish.

If High

High omega-3 index is protective for heart health.

Omega-3 Index: lifestyle and this value

Eat fatty fish at least twice per week (salmon, mackerel, sardines). Consider a quality omega-3 supplement if dietary intake is insufficient. Results typically improve within 2-3 months of consistent intake changes.

Omega-3 Index: frequently asked questions

What is a good Omega-3 Index?

An Omega-3 Index of 8% or higher is generally considered optimal for cardiovascular protection. Below 4% is considered high risk. Your healthcare provider can interpret your specific result.

How quickly can I improve my Omega-3 Index?

With consistent dietary changes or supplementation, improvements may be seen within 2-3 months, as the test reflects red blood cell turnover.

Is the Omega-3 Index better than measuring blood omega-3?

The Omega-3 Index reflects long-term omega-3 status (similar to HbA1c for glucose), making it more stable and clinically useful than a single blood measurement.
