InstalabOmegaCheck Panel
Should you take a OmegaCheck Panel test?
This test is most useful if any of these apply to you.
8 Biomarkers Included
- OmegaCheckAdds up the three marine omega-3 fats in your blood, eicosapentaenoic acid, docosahexaenoic acid, and docosapentaenoic acid, into one score. It is the panel's headline measure of whether your omega-3 reserves are high or low.A low total is the panel's clearest sign of weaker omega-3 protection and the first result worth acting on.
- Omega-6:Omega-3Weighs total omega-6 fats against total omega-3. A high ratio usually means omega-3 is relatively low, flagging a broad imbalance a single fat can hide.A high ratio most often reflects an omega-3 shortfall rather than dangerous omega-6 excess.
- AA:EPACompares arachidonic acid, an omega-6, against EPA, the two fats that compete for the same inflammation enzymes. A higher ratio leans pro-inflammatory.A high ratio suggests inflammatory signals have more raw material available than the calming ones.
- EPAThe other main fish-oil omega-3 and the direct competitor to arachidonic acid in inflammation pathways. Low EPA leaves inflammatory signaling less opposed.Low EPA relative to arachidonic acid points toward a more pro-inflammatory fatty-acid balance.
- DHAOne of the two main fish-oil omega-3 fats, most abundant in brain and heart tissue. It carries the strongest single link to lower coronary risk among the fats in this panel.Low DHA is associated with higher long-term heart-disease risk in large population studies.
- DPAA marine omega-3 your body makes from EPA. It adds information beyond EPA and DHA, with higher levels tied to lower heart-disease and diabetes risk.Low DPA alongside low EPA and DHA signals a broad marine omega-3 shortfall.
- Arachidonic AcidAn omega-6 fat and the raw material for many pro-inflammatory signals, though it is not simply harmful and also supports muscle and cognition.High arachidonic acid matters most when EPA is low, tilting the inflammation balance.
- Linoleic AcidThe most common omega-6 fat, from vegetable and seed oils. Moderate levels have been tied to lower heart-disease risk, so it is not a villain on its own.A high reading is not automatically bad and should be read alongside your omega-3 numbers.
About OmegaCheck Panel
You can eat salmon twice a week and still run low on the omega-3 fats your heart depends on. How much you eat and how much actually reaches your blood are two different things, because people absorb and store these fats at very different rates. This panel measures the fats themselves, so you work from what is inside your body rather than what is on your plate.
It reads two things at once: whether your omega-3 reserves are high or low, and how they stack up against the omega-6 fats that compete with them. Together those signals sketch the fatty-acid balance that emerging evidence links to long-term heart and inflammation risk.
What This Panel Reveals
The panel tells one story from three angles: how much marine omega-3 you carry, how omega-6 and omega-3 compare, and which side is winning the competition inside your cells. No single fat answers all three.
The first angle is your omega-3 supply. The headline number sums the three marine omega-3 fats in your blood: EPA and DHA (the two best-studied fish-oil fats, short for eicosapentaenoic acid and docosahexaenoic acid) plus DPA (docosapentaenoic acid, a related fat your body makes from EPA). In a pooled analysis of prospective studies, people with the highest blood levels of DHA had about 30% lower risk of coronary heart disease, and those highest in EPA about 15% lower, than people with the lowest levels. Suboptimal omega-3 status is common worldwide, so a low reading is not unusual.
The second angle is balance. Two omega-6 fats, linoleic acid (the main fat in vegetable and seed oils) and arachidonic acid (a fat your body builds from it), compete with omega-3 for the same spots in your cell membranes. The omega-6 to omega-3 ratio shows whether omega-6 dominates, which usually means omega-3 is relatively low rather than that omega-6 is dangerously high.
The third angle is inflammatory tone. Arachidonic acid is the raw material for many pro-inflammatory signals, while EPA feeds calmer ones, and the two compete for the same enzymes. The arachidonic-acid-to-EPA ratio captures which raw material is more available, and a lower ratio has been associated with lower cardiovascular risk, though that evidence comes largely from Japanese populations with high baseline EPA intake and is less established in Western groups.
How to Read Your Results Together
The patterns matter more than any one value. Here are the combinations worth recognizing in your own results. EPA, DHA, and AA below stand for eicosapentaenoic acid, docosahexaenoic acid, and arachidonic acid.
| Pattern | What It Suggests |
|---|---|
| Low total omega-3, high omega-6 to omega-3 ratio | Poor omega-3 status. This is the panel's clearest signal and the first thing to act on. |
| Adequate omega-3 but high AA to EPA ratio | EPA is low relative to arachidonic acid, tilting the balance toward pro-inflammatory signaling. |
| High linoleic acid, normal arachidonic acid, good omega-3 | Not a red flag on its own. Linoleic acid alone is not clearly harmful. |
| Low DPA alongside low EPA and DHA | A broad marine omega-3 shortfall rather than a single-fat gap. |
The single most useful reading is your total omega-3, especially the EPA and DHA portion. Across pooled coronary-disease data, the sum of EPA and DHA separated people with and without disease more consistently than any ratio, and the ratios mostly borrowed their predictive power from the omega-3 side. Treat a low omega-3 total as the finding to act on first, and use the ratios to add context.
What to Do with Your Results
If your omega-3 total is low, the most direct response is more marine omega-3, from oily fish or a fish-oil or algae-oil supplement. Blood omega-3 rises in proportion to the daily dose of EPA and DHA, and most of the increase from a steady dose lands within about three months. Plant sources such as flax are less reliable for raising these specific fats.
Because these fats sit in your cell membranes, levels move slowly and steadily rather than jumping after a single meal. Retesting about three months after any change gives the clearest read on whether it worked. If your results feed into managing high triglycerides or established heart disease, review them with your clinician, since omega-3 dosing and cardiovascular care decisions belong in that conversation. High-dose supplementation, above about 1 gram of EPA and DHA a day, has been linked to a higher risk of atrial fibrillation, an irregular heartbeat, which is one more reason to set the dose with a clinician rather than on your own.
Pair this panel with a standard lipid panel and a marker of inflammation to see the fuller cardiovascular picture. In one long-running cohort, people in the highest blood omega-3 group had a 39% lower risk of new cardiovascular disease and a 34% lower risk of death from any cause than those in the lowest, though omega-3 status is one input among several rather than a stand-alone verdict.
When Results Can Be Misleading
A few things shift the whole panel at once. Fatty-acid results reflect roughly the last few months of intake, so a recent change in diet or supplements will not fully show up yet. The exact numbers also depend on the lab method and blood fraction used, so track results over time from the same test rather than comparing across different labs. And omega-6 fats are not simply harmful: moderate linoleic acid intake has been tied to lower heart-disease risk, and arachidonic acid supports muscle and cognition, so a higher omega-6 reading is not automatically bad news.
