The short answer: a finger-prick Omega-3 Index test costs about £38–£50 in the UK, an omega-3 and omega-6 panel £70–£99, and broad health panels that include an omega ratio £150–£400. Here's where the differences come from, and the costs that aren't on the headline price.

Costs that aren't in the headline price
- Nurse or clinic blood draw: venous tests often add £35 (clinic) to £59 (home nurse). Finger-prick omega-3 tests don't need one.
- Return postage: check whether the return envelope is prepaid.
- Doctor's comments: some providers include them, some charge extra.
- The retest: most people retest after three months to see if a change worked, so the real cost is often two tests.
Results time matters too
Turnaround from the lab receiving your sample varies from about 3 working days to 2–4 weeks, depending on where the sample is analysed. If you're adjusting a supplement dose, faster results mean you start the right dose sooner.

Is the cheapest test the best value?
Not always. Check what's measured (the Omega-3 Index on the 8–12% scale), the analysis method (GC-FID), the turnaround, and whether you get a personalised dose. Our guide to choosing an Omega-3 Index test in the UK goes through each.
