Vitamin D + Omega-3 Index with AA:EPA and Omega-6:Omega-3 Ratios


Check your Omega-3 and vitamin D levels along with your AA:EPA and Omega-3:Omega-6 ratios.

The AA:EPA Ratio test measures the ratio of the amount of the omega-6 fatty acid arachidonic acid (AA) and the omega-3 fatty acid eicosapentaenoic acid (EPA) in the cells. This test is a measurement of the amount of bad fats to good fats in the cells, and it can be an indication of the amount of cellular inflammation in the body, since AA is pro-inflammatory and EPA is anti-inflammatory.  Experts recommend an AA:EPA Ratio of 3 or less to reduce levels of chronic inflammation and diseases related to chronic inflammation.

The Omega-6:Omega-3 Ratio test is another way to measure the amount of bad fats to healthy fats in the body. Omega-6:Omega-3 ratio is calculated by dividing the sum of seven omega-6 fatty acids by the sum of four omega-3 fatty acids. The desirable range for the omega-6:omega-3 ratio is 3:1 to 5:1, which was derived from thousands of individuals whose RBC samples were analyzed for the Omega-3 Index and for this ratio.

Both tests can provide guidance to specific dietary changes that could support improvements in chronic inflammation and disease.

These tests are only available as an add-on to your Omega-3 Index test, and uses the same samples provided on the Omega-3 Index blood spot card. This test is available in combination with the purchase of a vitamin D test only.
