Frequently asked questions

Why determine the HS-Omega-3 Index in red blood cells (erythrocytes) ?

From several investigations in humans we know that the HS-Omega-3 Index reflects the proportion of eicosapentaenoic and docosahexaenoic acids in important solid organs, like the heart. This is true for an unaltered diet, as it is true for a change in diet, e.g. after increased consumption of omega-3 fatty acids. Measurements in plasma do not reflect tissue levels, rather they reflect recent dietary intake, like a fish meal the previous evening. Therefore, plasma measurements do not permit assessing risk for cardiac disease, and are useless. That's why the HS-Omega-3 Index needs to be determined in red blood cells.

How often should the HS-Omega-3 Index be determined?

A repeat measurement of the HS-Omega-3 Index makes sense after 8 - 12 weeks, the earliest. This is because the fatty acid composition of red blood cells changes slowly. With an HS-Omega-3 Index within the target range between 8% and 11%, and an unaltered supply with omega-3 fatty acids, yearly controls suffice.

Should the HS-Omega-3 Index be measured as part of my check-up program?

Yes, this is also the opinion of many check-up centers, including Cooper Clinic, that currently use the HS-Omega-3 Index.

Who should have the HS-Omega-3 Index determined?

Convincing data support the determination in: Preliminary evidence supports determining the HS-Omega-3 Index in: Data are promising for determining the HS-Omega-3 Index in:

Is is possible to determine the HS-Omega-3 Index without venipuncture? Is there a self-test?

Yes, there is a self-test. It works similar to determining blood sugar from blood from a fingerprick. We can send you the necessary test kit.

Is it necessary to fast before blood is taken for the HS-Omega-3 Index ?

No. The easiest way is to have the blood taken with a routine blood withdrawal. For such a blood withdrawal, an overnight fast is usually required. Only for the self test an overnight fast is required.
