Your body needs essential fatty acids – Omega-3 and Omega-6 – to support heart, brain, joint, and immune health. But having the right balance is key. Too much Omega-6 or too little Omega-3 can increase inflammation, raise cardiovascular risk, and affect overall wellbeing.
The Omega-3 / Omega-6 Blood Test from Repose Healthcare provides a fast, private, and accurate way to measure your fatty acid profile and understand whether your diet is supporting optimal health.
Omega-3 and Omega-6 are polyunsaturated fatty acids (PUFAs) that play key roles in:
Brain function and mental health
Heart health – reducing triglycerides and inflammation
Joint mobility – reducing stiffness and pain
Immune response – balancing inflammation
Skin health – maintaining barrier function and hydration
While both are essential, a healthy Omega-6:Omega-3 ratio is crucial. Modern Western diets often contain too much Omega-6 (from vegetable oils and processed foods) and not enough Omega-3 (from oily fish, flax, walnuts), leading to a pro-inflammatory state.
Our at-home test analyses your blood sample for:
Omega-3 Index – the percentage of EPA + DHA in red blood cell membranes
Omega-6 Levels – including linoleic acid and arachidonic acid
Omega-6:Omega-3 Ratio – an important indicator of inflammation risk
Total Polyunsaturated Fatty Acid Profile – to help optimise dietary balance
This comprehensive analysis can help you adjust your diet and supplementation for improved long-term health.
This test is recommended for anyone who:
Eats little or no oily fish
Follows a vegetarian or vegan diet
Takes Omega-3 supplements and wants to track effectiveness
Has high cholesterol, cardiovascular risk, or inflammatory conditions
Experiences fatigue, poor concentration, or mood changes
Suffers from dry skin, joint pain, or autoimmune issues
Wants to optimise their diet for brain, heart, and immune health

1. What does an Omega-3 / Omega-6 blood test measure?
This test measures your Omega-3 index, Omega-6 levels, and your Omega-6:Omega-3 ratio. Together, these markers indicate whether you are getting enough Omega-3 fatty acids and whether your fatty acid balance supports healthy inflammation levels.
2. Why is the Omega-6:Omega-3 ratio important?
Both Omega-3 and Omega-6 are essential, but an imbalance (too much Omega-6, too little Omega-3) can lead to chronic inflammation. A healthy ratio supports heart health, brain function, and overall wellbeing.
3. Can I take this test at home?
Yes. Repose Healthcare provides an easy-to-use, finger-prick blood collection kit that you can use from home. Simply collect your sample, return it using the prepaid envelope, and receive secure online results within a few working days.
4. Who should consider this test?
This test is ideal if you eat little fish, follow a vegetarian or vegan diet, have cardiovascular risk factors, take Omega-3 supplements, or simply want to optimise your nutrition and inflammation balance.
5. What happens if my results are out of range?
Your report will include guidance on how to improve your results. This may include increasing Omega-3-rich foods like salmon, mackerel, flax, chia seeds, or considering supplementation.
6. How often should I re-test my Omega-3 levels?
If you change your diet or start supplementation, it is recommended to retest every 3–6 months to monitor improvement and ensure you are reaching optimal Omega-3 levels.
