The Biolab method for this profile is currently suspended due to staff sickness and we are therefore only offering a qualitative screen which we are referring to The University of Sterling for analysis (see separate link for sample report).
Over the past two decades there has been sustained interest in essential fatty acid supplementation. The focus has now switched from supplementation with fish oil to the use of oils containing specific, enhanced concentrations of named essential fatty acids. In the late 1990s large clinical trials such as the GISSI-Prevenzione study  were published supporting the cardiovascular benefits of consumption of omega-3 fatty acids. This trial, an Italian study of post-myocardial infarction patients, showed that after 3.5 years, those receiving n-3 fatty acids (850 mg/day) had a 20% reduction in overall mortality, 30% reduction in coronary mortality, and 45% reduction in sudden death.
Improved distillation processing has helped to enhance the purity of supplemental oils and there are now many studies to support the benefits of essential fatty acid supplementation that reach beyond the area of cardiology. To date studies which suggest that omega-3 fatty acid consumption has health-beneficial effects include those on the outcome of pregnancy [2,3,4], in the cognitive and visual development of the neonate [5,6], for the treatment and risk reduction of psychiatric disorders [7,8,9], in the prevention of dementia [10,11], metabolic syndrome [12,13] and a variety of other inflammatory conditions [14,15,16].
Biolab has re-established its measurement of red cell essential fatty acids with new instrumentation and is now reporting quantitative values on patient samples for seven omega-6 fatty acids, four omega-3 fatty acids, and a variety of omega-5, omega-7, omega-9, saturated and trans-fatty acids (32 fatty acids in total). Some of these substances are not considered beneficial to health (for example, the trans-fatty acids) and hence an overall assessment of dietary and supplemental intake of fatty acids can be made.
