What it measures
The total of all the omega-3 fats measured in the sample, such as EPA, DHA and ALA, as a percentage of all the fatty acids measured. It reflects omega-3 intake over recent weeks to months, depending on whether blood cells or plasma are tested.
Why people test it
- Looked at by people tracking how much oily fish or other omega-3 sources they eat.
- Reported as part of a fatty acid profile, alongside omega-6 and the ratio between them.
- Checked again after a change in diet to see how levels shift.
Typical range
There is no single agreed range. Ranges vary by lab, method (red cells, whole blood or plasma), age and sex, and your report shows the lab's own range.
Finger-prick or vein?
A finger-prick sample is usually fine, as fatty acid tests are often run on dried blood spots. Vein draws are offered too.
