Omega-3 Index, Homocysteine, Vitamin D Blood Test

The Omega-3 Index, Homocysteine, Vitamin D Blood Test measures three clinically important biomarkers linked to long-term metabolic health, cardiovascular risk, and nutrient status using a simple at-home dried blood spot sample.

The Omega-3 Index reflects the percentage of EPA and DHA in red blood cells and is strongly associated with long-term cardiometabolic balance inflammation status and overall heart health. Low Omega-3 Index levels are common even in individuals who supplement and may indicate increased cardiovascular risk.

Homocysteine is a functional marker of methylation and B-vitamin status including B12 B6 and folate. Elevated homocysteine levels are associated with increased cardiovascular risk impaired methylation and long-term metabolic dysfunction.

Vitamin D measured as 25-hydroxy Vitamin D 25(OH)D plays a central role in immune regulation bone metabolism hormone balance and systemic health. Suboptimal vitamin D levels are widespread and can impact cardiovascular metabolic and immune resilience.

Together the Omega-3 Index, Homocysteine, Vitamin D Blood Test provides a comprehensive overview of long-term cardiometabolic optimisation. This combined blood test allows you to assess fatty acid balance vascular risk markers and vitamin D status in one convenient home blood test kit.

Results are analysed in certified laboratories providing clinically relevant data to support personalised nutrition supplementation and long-term health strategy.

Ideal for individuals focused on proactive health monitoring metabolic optimisation cardiovascular wellness and evidence-based supplementation.

Frequently Asked Questions

What does the Omega-3 Index, Homocysteine, Vitamin D Blood Test measure?
This combined test measures three clinically important biomarkers: the Omega-3 Index (EPA + DHA % in red blood cell membranes), homocysteine (a marker of methylation and B-vitamin status), and 25-hydroxyvitamin D [25(OH)D]. Together, they provide insight into cardiovascular, metabolic, and immune health.

Why combine these three biomarkers?
Omega-3, homocysteine, and vitamin D are independent risk factors for cardiovascular and cognitive health. Suboptimal levels in any one of them are associated with increased inflammation, vascular stress, and chronic disease risk. Testing them together gives a more complete picture than any single marker.

Who should consider this test?
It's well suited to anyone focused on heart and brain health, methylation and B-vitamin status, or general healthy ageing. It's also useful for individuals with a family history of cardiovascular disease, low fish intake, limited sun exposure, or plant-based diets.

How is the sample collected?
The test uses a single dried blood spot (DBS) card. A few drops from a fingertip cover all three biomarkers — no venous blood draw or clinic visit required.

Do I need to fast before the test?
Fasting is not required. Testing in the morning before food or supplements helps ensure consistency for homocysteine.

How accurate is the test?
The Omega-3 Index is analysed by gas chromatography; homocysteine and vitamin D are analysed by LC-MS/MS. These are the same clinically validated methods used in hospital and research laboratories.

How long does it take to get results?
Results are available 3–5 business days after your sample arrives at the lab.

Where is my sample analysed?
Samples from the Asia-Pacific region, including Australia and New Zealand, are analysed in our accredited laboratory in Australia. Samples from Europe and the United Kingdom are processed in our certified EU laboratory, ensuring all results meet international clinical standards for accuracy and reliability.
