Omega 3 Index (Red Cell) – Blood Spot (Test Code 5029)

Omega‐3 fatty acids are essential to the human body and have benefits for our heart, brain, eyes and joints. By reducing inflammation, blood clots and improving membrane function, omega‐3 fats are associated with a lower risk of heart complications – including heart disease, plaque build‐up and heart attacks – both in persons with a history of heart disease and in healthy individuals. Omega‐3 fats are important for optimal brain development in babies and mental function, particularly later in life.

Red cell and whole blood (dried blood spot) analyses can provide the best reflection of tissue omega‐3 fatty acid status, as there is considerably more day‐to‐day variation in the plasma tests than in the RBC (or whole blood)-based tests.

In addition to the Omega‐3 Index, we also provide, at no additional charge, a complete fatty acid profile including 4 omega‐3 fatty acids, 7 omega‐6 fatty acids, 4 monounsaturated fatty acids, 6 saturated fatty acids, 3 groups of trans fatty acids, 5 composites (group sums) and 2 ratios.

We provide two fatty acid ratios: the omega‐6:omega‐3 and AA:EPA. Although we include these values, we believe that the Omega‐3 Index is the most important (and actionable) component.

We would suggest that for the dried blood spot assay, the omega‐6/omega‐3 ratio should be 4.6 or less, and the AA/EPA ratio should be 9 or less.

For the red blood cell assay, the omega‐6/omega‐3 ratio should be 2.6 or less, and the AA/EPA ratio should be 15 or less.

The reference ranges provided give an idea of how these values compare to a large number of others taken from a relatively healthy population. Although average, these are not necessarily optimal levels, i.e., target levels or levels that one should to attempt to achieve. The result providing an actual target or optimal level is the Omega‐3 Index since it has undergone the most research.
