Essential fatty acids regulate cell membrane integrity, blood pressure and coagulation, lipid levels, immune response, tumor growth and inhibition, and the inflammatory response to injury and infection. Erythrocyte Fatty Acid testing aids in developing the most efficacious dietary and supplemental treatment program to restore appropriate ratios among fatty acids.

Fatty acids are primarily derived from triglycerides in the food and oils that we consume. Non-essential fatty acids are also biosynthesized in the body, especially during times when carbohydrate intake exceeds the body's needs for glucose and glycogen repletion. Non-essential fatty acids are most commonly recognized as an important source of energy, and when caloric intake exceeds expenditure, these FAs are stored in adipose tissue as triglycerides. However, fatty acid metabolism is much more complex and it is well established that appropriate balance among essential and non-essential FAs, as well as avoidance of harmful trans-fatty acids, is required for optimal health and wellness.

This test is useful for the following:

  • Alzheimer's Disease
  • Autism Spectrum Disorders
  • Blood Pressure
  • Cardiovascular Health
  • Coagulation
  • Lipid/Lipoprotein Levels
  • Immune Response
  • Inflammatory Response to Injury and Infection
  • Seizure Disorders
  • Tumor Growth and Inhibition
