Essential & Metabolic Fatty Acids Analysis (EMFA). This test evaluates the level of red cell membrane fatty acids, imbalances of which significantly affect inflammatory and other disorders. By knowing the various fatty acid levels, one can re-establish a balance using nutritional intervention.This comprehensive profile allows practitioners to accurately assess dietary intake and metabolism of fatty acids in each patient. Precise, custom-tailored nutritional intervention is then made possible. Fatty acids comprise some of the most essential nutrients in the human diet. They are critical for cell membrane structure and function as well as local “hormonal” signaling. Essential fatty acids (EFAs) are transformed into local hormonal mediators called eicosanoids. Eicosanoids regulate all stages of inflammation, including initiation, propagation and termination. This process is vital to the ability of the body’s immune system to repair and protect itself. Fatty acids are also crucial components of neural membranes and receptors that ensure proper intracellular communication within the brain and nervous system.
