We don't cut corners on the science. Every part of our testing process is accredited, externally verified, and quality-reviewed.
GC-FID Reference Method
Gas chromatography with flame ionisation detection — the reference method for fatty acid analysis, used in the published omega-3 trials behind the Omega-3 Index. No immunoassay shortcuts.
The original Omega-3 Index method
The validated method defined by Harris & von Schacky (2004), now referred to in more than 500 published papers — the recognised marker of omega-3 status, not a generic wellness panel.
Quality-Reviewed
Every analytical run includes internal standards and QC controls. Out-of-range results are reviewed by a qualified scientist before release.
Accredited lab, UK service
Analysed by GC-FID in an accredited laboratory. UK customer service, billing and shipping. Email responses within one business day.
Before you order
The questions most people ask before placing their first test.
How is the test collected?
A small finger-prick onto a dried blood spot card included in the kit. Two minutes, no needle, no nurse. Full step-by-step instructions are inside the box.
Do I need a doctor's referral?
No — our tests are direct-to-consumer. Many customers share their results with a GP, midwife or nutritionist afterwards (the report is formatted like a pathology report for that exact reason), but no referral is required to order or to receive your result.
What's the difference between the four tests?
Index Basic reports EPA+DHA as your Omega-3 Index. Plus Ratios adds the omega-6 : omega-3 and AA : EPA ratios plus Trans Fat. Complete is the full 24 fatty acid panel — the same depth used in clinical research. Prenatal Omega-3 measures DHA with pregnancy-tuned reference ranges. All four use the same finger-prick kit and the same accredited lab.
Why should I get the 2-pack?
Two reasons. Track your change — omega-3 levels in red blood cells take 8–12 weeks to fully reflect any dietary or supplement change. A baseline + 3-month retest tells you whether what you're doing is actually working. Or share with someone — partner, parent, sibling. Same household, two reports.
How long until I get my results?
3–5 business days from the day your sample arrives at the lab. We email you the moment your report is ready and you can download it as a PDF.
Is shipping really free?
Standard shipping is free across the UK. We post you the kit with a prepaid return envelope to send your sample back to the lab. Need it faster? Express delivery (1–2 days) is available at checkout.
How do I get the 10% discount?
Sign up to our newsletter — we'll email you a one-time 10% discount code (OMEGA10) valid on any single test.
Stop guessing. Know your number.
The whole process takes less time than booking a GP appointment — and tells you exactly where you sit on the omega-3 reference scale.
