DIAGNOSTIC OVERVIEW

What Omega Index Is

Omega-3 and omega-6 are essential fatty acids, meaning your body cannot make them and has to get them from your diet. This test measures both from a standard blood sample, along with the ratio between them, which is often more informative than either figure alone.

Why it's worth it

Measured, not assumed.

One draw, alongside your other bloods.

A marker that responds to change.

DIAGNOSTIC DETAILS

What it measures

The panel reports your omega-3 index, your omega-6 levels and the balance between the two. These are nutritional markers, associated with dietary intake and studied in relation to cardiovascular and inflammatory health, and are read alongside your wider results.

Omega-3 Index

Your omega-3 level is measured directly rather than estimated from what you think you eat, which is where most people's assumptions turn out to be wrong.

The Balance Between

The ratio between the two is often more informative than either number on its own.

Omega-6 Levels

Omega-6 is measured alongside it, since modern diets tend to supply plenty of it and the picture is incomplete without both.

Responsive To Diet

These levels shift with what you eat, so a retest genuinely shows whether a change worked.

HOW IT WORKS

From booking to your results

An assumption replaced by a number. Here is how an Omega Index goes from a single blood draw to guidance you can act on.

Speak with your clinician

An Omega Index is clinician selected, so it starts with a short conversation about whether it adds something useful to your wider picture.

Give your sample

A standard blood draw at a partner collection centre, usually five to ten minutes. Where possible it is collected alongside your other bloods, so there is no separate trip.

Laboratory analysis

Your sample is analysed by an accredited pathology laboratory, measuring your omega-3 and omega-6 fatty acid levels and calculating the balance between them.

Results in the app

Your levels land in the Precursor app in plain language, set against reference ranges so you can see where you sit rather than facing a raw laboratory figure.

Review and adjust

A clinician or dietitian explains what your levels mean and what, if anything, is worth changing in your diet. Because this marker moves, you can retest later and see the difference.

"This is one of the few markers where someone can change what they eat, retest a few months later, and see it clearly on paper. That feedback loop is what makes advice stick."

FAQs

Your Questions, Answered

How do I book a test?

Choose your test and a time that suits you online, then visit one of our partner locations. If any preparation is needed, such as fasting, we tell you clearly when you book.

When and how do I get my results?

Your results appear in the Precursor app once your sample or scan has been processed, laid out in plain language rather than a wall of numbers. Turnaround depends on the test, and we give you a timeframe when you book.

Will someone explain my results to me?

Yes. A clinician reviews your results, flags anything worth your attention and helps you understand what they mean and what, if anything, to do next. You are never left to interpret them alone.

Where can I get tested?

We operate through partner locations across South East Queensland, including Brisbane, the Gold Coast and the Sunshine Coast. You choose the most convenient one when you book.

Do I need to prepare or fast beforehand?

It depends on the test. Some require fasting or other simple preparation, and others need nothing at all. Whatever applies, we tell you clearly at the time you book so there are no surprises on the day.

Can I track my results over time?

Yes. The Precursor app is built to show change between tests, so each result becomes a trend you can follow rather than a one-off snapshot. Retesting lets you see the effect of any changes you make.

How is my data handled and kept private?

Your health data is handled with care and kept private. Results are stored securely in the Precursor app and shared only with you and the clinicians involved in your care.

What happens if something needs further attention?

If your results surface something worth acting on, your clinician explains it calmly and talks you through sensible next steps. The aim is early clarity and considered action, never unnecessary alarm.

What is a good BRI score?

There is no single answer, because it depends on your height and which guidance you are being measured against. This calculator converts the Australian waist thresholds into BRI at your own height, so your bands are specific to you. Most BRI tools use bands from an American mortality study, which produce noticeably different results for Australians.

Is BRI better than BMI?

It is better at one specific thing, which is detecting central fat, because it uses your waist. It is not better across the board. BMI is generally reliable when it flags someone, and research suggests the two measures agree in the large majority of cases. The useful comparison is not which one wins but whether they disagree about you.
