Fish Oil (Omega-3 Fatty Acid) Profile by Interphase Chromatography
This test measures levels of key omega-3 fatty acids—such as eicosapentaenoic acid (EPA) and docosahexaenoicenoic acid (DHA)—found in fish oil. It helps assess your intake of these beneficial fats, which support heart, brain, and joint health.

Why This Test Matters
Omega-3 fatty acids are essential nutrients linked to reduced inflammation, improved heart function, and cognitive health. Many people get these fats from fish, flaxseeds, or supplements. This test helps determine if your levels are sufficient or if you may need to adjust your diet or supplement use.
How the Test Works
This test uses a specialized chromatography method to separate and measure different omega-3 fatty acids in your blood sample. It identifies key compounds like EPA and DHA, which are critical for health. The results provide a snapshot of your current omega-3 status.
What to Expect Before the Test
No special preparation is needed for this test. You may have a blood draw, urine sample, or other fluid collected depending on the specific test protocol. If you’re taking omega-3 supplements, let your healthcare provider know, as this may affect results.
Common Uses for This Test
Healthcare providers may order this test to evaluate omega-3 intake, especially in people with heart disease, high triglycerides, or symptoms of deficiency. It can also help monitor supplement effectiveness or guide dietary recommendations.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Low levels of omega-3 fatty acids may increase inflammation, raise triglycerides, or contribute to cardiovascular risks. High levels, however, can be dangerous if caused by excessive supplementation. Your doctor will interpret results in the context of your overall health and medical history.
