What it measures
Total omega-6 fats divided by total omega-3 fats, both measured in the same sample. It is worked out from the two results and shows the balance between the two families of fats.
Why people test it
Looked at by people tracking the balance of omega-6 and omega-3 fats in their diet.
Reported as part of a fatty acid profile.
Checked again after a change in diet to see how the balance shifts.
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?
Taken from a vein. Providers offer it only as a vein draw, at a clinic or with a visiting nurse.
