Measures your omega-3 and omega-6 fatty acid levels and the balance between them, relevant if you eat oily fish less than twice a week or want to understand your intake of these essential fats. Collected at home with a finger-prick kit.
1 biomarker as listed by Better2Know.
Omega-3 and omega-6 are essential fatty acids that the body cannot make itself, so they have to come from the diet, mainly oily fish for omega-3 and vegetable oils for omega-6. This test reports your levels of both and how they relate to each other, which is commonly used as an indicator of dietary intake, particularly if you eat oily fish less than twice a week. It measures this as a single combined marker rather than breaking out individual fatty acids.
Against the other omega-3 tests we track, £125 is below the £160 median for this comparison group and £70 cheaper than Better2Know's own clinic-based version of the same test, though Bluecrest Wellness's Omega-3 Index Test undercuts it at £85. That relative pricing is why it scores reasonably well on value for money. It also scores well on collection convenience, since you can complete it at home with a finger-prick kit rather than attending a clinic, and on clarity, because the listing sets out the biomarker, sample type and turnaround clearly.
Trust-signal scoring reflects Better2Know's 4.2 Trustpilot rating from 775 reviews, its CQC registration and 18 years of trading. Clinical depth still scores reasonably, since it measures exactly the single combined marker it claims to; the weaker score is for results and follow-up, because the result is not reviewed by a doctor as standard.
This suits you if you want a straightforward, at-home check of your omega-3 and omega-6 levels, for example because you rarely eat oily fish and want to understand your intake, and you would rather avoid Better2Know's £195 clinic-based version for the same result. If price is the priority, Bluecrest Wellness's Omega-3 Index Test at £85 is cheaper for the same single marker. Because there is no doctor review as standard, use this to track your own levels rather than to investigate symptoms, for which a GP visit is more appropriate.
You collect a finger-prick blood sample at home using the kit provided and post it to the lab; a venous draw at a Better2Know clinic is also available for £195. Results are typically ready within about 4 working days of the sample reaching the lab and are provided through Better2Know's online patient area. The fact sheet does not state that a doctor reviews results as standard.
For £125, this at-home finger-prick kit checks your omega-3 and omega-6 fatty acid levels, £70 less than Better2Know's own clinic-based version of the same test but £40 more than Bluecrest Wellness's Omega-3 Index Test at £85. You collect the sample yourself and post it to the lab. Results are not doctor-reviewed as standard.
