Clinical Overview

Essential fatty acids are integral component of cell membranes making them critical to proper cellular function and communication. Improper fat intake and impaired fat digestion, absorption, and/or metabolism may result to essential fatty acid deficiency.1

The Essential Fatty Acids Panel measures a wide array of omega acids (Omega-3, Omega-6, Omega-9, and saturated fatty acids) in relation to the total fatty acids. The ratio of Omega-3 to Omega-6 and Arachidonic Acid (AA) to Eicosapentaenoic Acid (EPA) are included as inflammatory markers. EPA and AA are the key EFAs modulating inflammation. A high AA:EPA ratio indicates increased levels of inflammation in the body and has been detected in patients with insulin resistance, coronary artery disease and depression. Published data supports Omega-3 fatty acid levels as a modifiable risk factor for primary and secondary prevention of cardiovascular disease.2

The analysis of fatty acids in red blood cells measures its 120-day lifespan in blood circulation. Unlike serum or plasma, this reveals the metabolic functions and dietary intake factors on a longer time scale that can be used as a biomarker for fatty acid metabolism, diet-disease correlation, and epidemiological studies.3
