Omega-6/Omega-3 Ratio
LOINC 90910-1 · ratio
What it is
This ratio compares total omega-6 to total omega-3 fatty acids in your blood, summarising the overall balance of the two families.
Why it matters
The balance between omega-6 and omega-3 is studied in relation to inflammation and long-term heart health, which a single ratio captures conveniently.
What high values can mean
A higher ratio means relatively more omega-6 than omega-3, a balance often described as more pro-inflammatory.
What low values can mean
A lower ratio means relatively more omega-3, generally regarded as a more favourable balance.
How to improve it
Eating more oily fish and omega-3 sources, and moderating excess omega-6 oils, typically lowers the ratio.
Food & lifestyle
Oily fish, walnuts and flaxseed raise omega-3; heavy use of refined omega-6 oils and fried/processed foods raises omega-6.
Preparing for the test
Part of a fatty-acid (omega) profile; fasting is usually not required — follow your lab's instructions.
When to talk to a doctor
Best reviewed with a clinician as a trend rather than from a single reading.
