  • Omega-3 Index (EPA + DHA)

About this test

The Omega-3 Index measures the percentage of EPA and DHA, two essential omega-3 fatty acids, in your red blood cells. This is used as a longer-term marker of omega-3 status than a single blood fat reading, with higher levels commonly associated with cardiovascular and cognitive health, and Bluecrest cites 8% or higher as a typical optimal range.

As a single-marker test, clinical depth is not the differentiator here. Price is: at £85, it is 47% below the £160 comparison-group median, and notably cheaper than Better2Know's comparable omega-3 and omega-6 tests, priced from £125 to £195 in our data.

Clarity scores well, with a detailed description, the marker clearly named, sample type and turnaround all stated. One practical catch, shared with Bluecrest's Inflammatory Profile, is that this test can only be booked by phone rather than online. Results and follow-up score lower because there is no doctor review included as standard.

Who is it for?

This suits you if you want a long-term read on your omega-3 status, for example to check whether dietary changes or supplementation are having an effect, and you don't mind booking by phone rather than online. On price, it compares well: Better2Know's equivalent tests cost £125 to £195 for the same type of measurement. If you have diagnosed cardiovascular disease, discuss omega-3 supplementation with your GP rather than acting on this result alone.

How it works

This is a blood test collected by venous draw at a local Bluecrest venue; Bluecrest notes it can only be booked by phone rather than online, and can be added to any full health check. Once processed, results are typically returned in around 3 to 8 days, along with personalised recommendations based on your result. There is no doctor review included as standard.
