Is the Omega-3 Index Test Covered by Medicare in Australia?

If you've searched for an omega-3 blood test in Australia, you've probably wondered whether Medicare will cover it or whether your GP can bulk-bill it. Here's the plain-English answer, what it actually costs, and the one situation where omega-3 testing is already free.

Why isn't the Omega-3 Index covered by Medicare?

The Omega-3 Index — EPA + DHA measured as a percentage of your red blood cell fatty acids — simply isn't on the Medicare Benefits Schedule (MBS). Standard GP-ordered pathology in Australia measures things like cholesterol, glucose, iron and vitamin D, but none of those panels include your omega-3 status. Because there's no MBS item number, there's no Medicare rebate and it can't be bulk-billed — the test is paid for privately, the same way it works in the UK, US and most of the world.

Do I need a GP referral?

No. Omega-3 Index testing is direct-to-consumer — you don't need to see a GP or get a referral. You order online, collect a finger-prick blood sample at home, and post it to the lab. Many people then share the report with their GP, midwife or dietitian afterwards (it's formatted like a pathology report), but that's optional.

How much does an Omega-3 Index test cost in Australia?

Prices vary by provider and by how much detail you want. Our at-home tests, analysed by GC-FID at an accredited Australian lab with results in 3–5 days:

Shipping is free both ways, and there's no consultation fee — so the sticker price is the full cost.

Is omega-3 testing ever free in Australia?

Yes — in one situation, and it's a sign of where things are heading. From 2026, South Australia became the first place in the world to offer omega-3 (DHA) status testing free to pregnant women, through SA Pathology as part of routine antenatal care. It's the result of decades of research led by the South Australian Health and Medical Research Institute (SAHMRI), which showed that omega-3, targeted to women who start pregnancy with low levels, substantially reduces the risk of early preterm birth.

If you're pregnant outside South Australia — or you're in the SA program and want to monitor your level at home between visits — our Prenatal Omega-3 Test gives you the same measurement, posted anywhere in Australia, on the same pregnancy-tuned scale. More on the program in our guide to the SAHMRI Omega-3 Test-and-Treat program.

How to get your Omega-3 Index without Medicare

You don't need a rebate or a referral to find out your number:

• Order an at-home kit online — pick the test that matches what you want to learn.
• Collect at home — one finger-prick onto the dried blood spot card. No fasting, no clinic.
• Post it back in the reply-paid envelope, and get your report in 3–5 days.

Common questions

Is the Omega-3 Index test on Medicare?

No. There is no MBS item number for the Omega-3 Index, so it isn't Medicare-rebatable.

Can I get an omega-3 test bulk-billed?

No — because it isn't covered by Medicare, it can't be bulk-billed. You pay privately.

Do I need a doctor's referral?

No. At-home omega-3 tests are direct-to-consumer and don't require a GP referral.

How much does an Omega-3 Index test cost?

Typically $89.95 for a basic Omega-3 Index up to about $109.95 for a full 24-fatty-acid profile, depending on the provider and test.

Is omega-3 testing free anywhere in Australia?

Yes — free for pregnant women in South Australia through SA Pathology as part of routine antenatal care, with a national rollout in progress.
