Why it matters

A higher Omega-3 Index is linked to lower risks of cardiovascular disease, cardiovascular events (such as heart attacks), and death.

Reference ranges

The reference range for Omega-3 Index reflects recommendations from the testing laboratory as well as cutoffs established in research studies. Your Omega-3 Index should be interpreted in conjunction with your other results to get the best understanding of your overall cardiac risk profile and health status.
