Essential Fatty Acids (EFA) – RBCs Quantitative

Beschrijving

Overview

Essential fatty acids (EFAs) are vital building blocks for cell membranes, hormones, and inflammatory mediators. This test provides a detailed quantitative analysis of the major fatty acid classes Omega-3, Omega-6, Omega-7, Omega-9, and saturated fatty acids in blood.

Assessing fatty acid status helps clinicians understand nutritional balance, cardiovascular and neurological health, inflammatory processes, and overall metabolic well-being.

Clinical Relevance

• Omega-3 fatty acids (ALA, EPA, DHA): Linked to heart health, brain function, vision, and anti-inflammatory pathways.
• Omega-6 fatty acids (LA, GLA, AA): Important for skin, immunity, but imbalances may contribute to inflammation.
• Omega-7 and Omega-9 fatty acids: Involved in lipid metabolism, energy regulation, and nerve function.
• Saturated fatty acids: Provide structural stability to cells; excess may relate to metabolic stress.

Key ratios, such as AA/EPA and Omega-6/Omega-3, offer insights into the body’s inflammatory balance. The Omega-3 index is widely recognized as a cardiovascular and neurological risk marker.

Who Should Consider This Test?

• Individuals with cardiovascular risk factors (cholesterol imbalance, hypertension, family history).
• Patients with chronic inflammation, autoimmune conditions, or skin disorders.
• Those with cognitive or mood changes, fatigue, or neurological concerns.
• People on restrictive diets (vegetarian, vegan, ketogenic) where fatty acid intake may be imbalanced.
• Anyone undergoing nutritional optimization, preventive health, or longevity programs.

Report Example
