Low levels of essential omega-3 fatty acids, linked to higher cardiovascular and inflammatory risk. Blood testing measures the omega-3 index, guiding dietary or supplement correction.
Our comprehensive check-up screens for omega-3 deficiency and hundreds of other conditions.
The Omega-3 Index measures the percentage of EPA and DHA (the two most important omega-3 fatty acids) in red blood cell membranes. It reflects your long-term omega-3 status over the past 3–4 months and is considered one of the most reliable markers of cardiovascular risk related to fatty acid balance. An index above 8% is associated with the lowest cardiovascular risk.
Total Omega-3 fatty acidsThis sum represents all major omega-3 fatty acids (ALA, EPA, DPA, DHA) in the blood.
Eicosatrienoic acid (omega-3, ETA)Eicosatrienoic acid is an intermediate omega-3 fatty acid formed during the conversion of ALA to EPA. It contributes to anti-inflammatory lipid signaling pathways.
Eicosapentaenoic acid (omega-3, EPA)EPA is a long-chain omega-3 fatty acid mainly found in fatty fish. It helps regulate inflammation and supports heart and blood vessel health.
Docosapentaenoic acid (omega-3, DPA)DPA is a long-chain omega-3 fatty acid formed as an intermediate between EPA and DHA. It contributes to anti-inflammatory and endothelial-protective effects.
Docosahexaenoic acid (omega-3, DHA)DHA is a structural omega-3 fatty acid essential for brain, eye, and nerve function. It is abundant in neuronal membranes and supports cell signaling.
Alpha-linolenic acid (omega-3, ALA)Alpha-linolenic acid is a plant-derived omega-3 fatty acid found in flaxseed, chia, and walnuts. It serves as a metabolic precursor for longer-chain omega-3 fatty acids such as EPA and DHA.
