DHA
LOINC 90914-3 · %
What it is
DHA (docosahexaenoic acid) is a long-chain omega-3 fatty acid, reported as a percentage of your blood fatty acids. It is a key building block of the brain and retina.
Why it matters
DHA levels reflect your omega-3 intake and are studied in relation to brain, eye and cardiovascular health.
What high values can mean
A higher percentage usually reflects a good omega-3 intake and is generally regarded as favourable.
What low values can mean
A lower percentage often reflects limited intake of oily fish or omega-3 supplements.
How to improve it
Eating oily fish a couple of times a week, or supplementing under guidance, typically raises DHA.
Food & lifestyle
Salmon, sardines, mackerel, anchovies and algae-based supplements are the richest sources of DHA.
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
Discuss with a clinician if you are pregnant, planning pregnancy, or addressing heart or cognitive health.
