This test measures omega-3 and omega-6 fatty acid levels in your blood. Omega-3s help reduce inflammation and support heart and brain health, while omega-6s are important for growth and development but can cause inflammation if you have too much compared to omega-3s. The test is important because it helps you understand if you have the right balance of these fats. Maintaining a good balance can lower your risk of chronic diseases like heart disease and arthritis, and improve overall health.
