Dietary Fatty Acids

Dietary fatty acids tests measure the types and balance of fats in your blood—especially omega-3 (EPA, DHA) and omega-6 (linoleic acid/arachidonic acid)—to give an objective view of heart, brain, eye, and metabolic health support. Because food logs and memories are imperfect, blood testing offers a clear, trackable baseline, helps you and your clinician fine-tune diet and supplements, and shows whether changes are taking hold.

A proactive plan often starts with the Omega-3 Index and the omega-6:omega-3 ratio, then adds targeted markers such as EPA%... See more

The Omega-3 and Omega-6 Fatty Acids Test measures essential fatty acids, including EPA, DHA, and arachidonic acid, to assess balance between omega-3 and omega-6 in the blood. This ratio is linked to heart health, inflammation, brain function, and metabolic wellness. Doctors use this test to evaluate diet quality, detect deficiencies or excess, and guide nutrition or supplement plans that support cardiovascular, cognitive, and overall long-term health.

Also Known As: OmegaCheck® Test

The Very Long Chain Fatty Acids (VLCFA) Test measures C22:0, C24:0, C26:0 and ratios (C24/C22, C26/C22), with phytanic and pristanic acids, by GC/MS to assess peroxisomal function. Abnormal VLCFAs support evaluation of X-linked adrenoleukodystrophy and Zellweger spectrum disorders, informing diagnosis of peroxisomal and neuro-metabolic disease in the right clinical context.

The Beta-Hydroxybutyrate Test measures levels of beta-hydroxybutyrate, the primary ketone body in the blood, to assess ketosis and detect ketoacidosis. Elevated BHB is commonly associated with diabetic ketoacidosis, prolonged fasting, alcohol-related ketosis, or metabolic disorders. This test helps monitor ketone production, evaluate metabolic health, and distinguish between nutritional ketosis and pathological states.

The Nonesterified Fatty Acids Test measures circulating free fatty acids, important indicators of lipid metabolism and energy balance. Abnormal levels may signal insulin resistance, diabetes, obesity, or metabolic syndrome. This test supports evaluation of cardiovascular risk, liver function, and disorders related to fat mobilization, helping providers assess how the body regulates fat breakdown and energy use.

The Comprehensive Fatty Acid Profile (C8–C26) analyzes 40+ fatty acids in serum—including medium, long, and very long chain species—to evaluate mitochondrial β-oxidation, peroxisomal disorders, essential fatty acid deficiency, or nutritional status. Abnormal patterns (e.g. elevated VLCFAs, altered w3/w6 ratios) help detect metabolic or peroxisomal defects and guide dietary or therapeutic interventions.

A dietary fatty acid deficiency is rare. But people who suffer from it could experience debilitating effects.

However, it can be difficult to determine whether you actually have it or not. After all, the symptoms could be indicators of other conditions.

The chances are that if you are reading this page, you have a good reason for suspecting dietary fatty acid deficiency.

If that’s the case, our service at Ulta Lab Tests provides plenty of lab tests to screen for abnormal fatty acid levels along with many other dietary deficiencies.

But first, you might want to understand what this condition is and whether you have reason to be concerned.

So, keep reading to learn about what a dietary fatty acid deficiency is. This article will cover a general overview of dietary fatty acid deficiency and what tests can confirm or deny this condition.
