Essential Fatty Acids are not made by the body but should come from our diets. Omega-3 and Omega-6 are such Fatty Acids that have important roles in human health. They are important for healthy heart, lungs, brain, eyes, joints as well as a robust immune system, and well-balanced hormones. Good sources of Omega-3 include fish oil, flaxseed, soybean, canola oil and seafoods.
Using a few drops of blood with a finger prick, this at-home Omega-3 blood test measures 42 markers, ratios, and summaries including healthy range of Omega-3 fatty acid index. Check out a sample report link below to see the full list of markers.

Omega-3 fatty acids are part of the membranes surrounding each cell. They are commonly found in food rich in fish oil, plant based oils and dietary supplements.
These fatty acids play important roles in healthy heart, eyes, brain, immune system, joints, lungs, blood vessels, and hormone balance.
There is a long list of fatty acids, but the three key ones are AHA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid). AA (arachidonic acid) is another important Omega-6 fatty acid.
Because our body doesn’t make most of these fatty acids in sufficient amount, foods such as flaxseed, fish oil, canola oil, soybean, seafood, and dietary supplements are the main source of them.
The test will provider 42 values, ratios and summaries for the following:
Red Cell Fatty Acids (Summary)
Saturated Fatty Acids (Total)
Monosaturated Fats (Total)
Omega-3 Fatty Acids (Total)
Omega-6 Fatty Acids (Total)
Omega-3 to Omega-6 ratio - our bodies can’t make trans fats; industrial sources of these fats have impacted our cardiovascular health; low values are considered healthy.
AA/EPA ratio: a marker of Omega-6 to Omega-3 ratio; research suggests an AA/EPA ratio of 1.5 is ideal, over 3 is acceptable, but over 10 is risky.
Omega-3 Index: an indication of overall health; a low Omega-3 FA index (below 4) is associated with an increased risk for CVD.

Trans Fat Index
The Omega-3 index is a range defined based on EPA and DHA levels for optimal health. A value over 4 is considered desirable and can be improved by consuming optimal amounts of foods rich in Omega-3 fatty acids.
Using Gas Chromatography–Mass Spectrometry (GC/MS), this test delivers highly sensitive and precise quantification of fatty acids for accurate clinical interpretation.
Because they play an important role in heart health, immune system, and healthy brain, eyes, joints, and endocrine system, it’s vital to monitor Omega-3 levels. The Office of Dietary Supplements at NIH says optimal levels play key role in managing chronic diseases, cardiovascular disease, in the development of babies, and in avoiding Alzheimer’s and dementia. Omega-3 acids also help in preventing dry-eyes, arthritis, and pain in joints.
The Omega-3 fatty acids are naturally found many foods in our diets:
Fish and seafoods (cod, krill, salmon, tuna, trout, mackerel, sardines, herring, and other fatty fish).
Plant based oils (soybean, canola, flaxseed).
Many nuts and seeds (chia, flaxseed, walnuts).
Dietary supplements (e.g., fish oil, krill oil, cod liver oil, algae oil).
Specific fortified foods (including certain eggs, milk, yoghurt, juices, soy milk, and formulas).
The Omega-6 fatty acids, e.g., AA (arachidonic acid) are supplied by dietary animal sources, such as eggs and meats.
The easiest low-cost way to get tested for Omega-3 fatty acids is from the convenience of your home. Simply order a Essential Fatty Acids and Omega-3 Test kit, collect the sample at home, ship it for free to our world class CLIA-certified labs, and find out your results in less than a week.
Follow the NIH page for detailed discussion about Omega-3, sources, deficiency, and published research here.
A: Except New York the test is available in all 49 states. State regulations in NY do not allow us to ship the tests to their residents (you will need to receive, collect and mail it from outside NY, if needed).
A: The Omega-3 test kit contains a blood card to collect a single drop of blood, a lancet for finger-pricking, a band-aid, a cotton gauze, instructions on how to collect the sample, and a form requesting basic information including date and time of collection. The directions are straightforward and easy to follow.
A: You will receive the kit within 3-5 business days. After you ship the sample and it is received by our lab, you get the results within 5-7 business days.
A: The report with your test results will be easy to understand and will have all the necessary details. It will list your levels for Omega-3 fatty acids and the Index with desirable levels. It will also mark the ranges, and list values for multiple fatty acid groups.
A: You can use HSA (or FSA/MSA/HRA) accounts to pay for the tests since these are prescription tests (for further confirmation, please check the IRS publication#969). However, please ensure you are not going outside your specified max and min deductible limits. We do not have the capability to process the insurance claim. Insurance plans vary by individuals, therefore we can not guarantee your HSA payment will always be processed by your plan. Please talk to your insurance provider if you have any further concerns.
A: For testing your samples, we have partnered with CLIA-certified labs that are used by physicians across the US. These labs are regulated by the states, as well as Centers for Medicare and Medicaid Services (CMS). Many the tests from these labs are FDA approved to ensure they meet the proper regulatory requirements. Additionally, the College of American Pathologists (CAP) requires inter-laboratory tests to ensure the ranges established by each lab do not drift or are not out of acceptable ranges. This is done by regularly testing reference samples between different labs. Finally, the labs test thousands of sample for different age groups and health conditions, and have well established reference data to compare your results against this large pool.
Our at-home Omega-3 test kit can help understand your body’s level of fatty acids, before you add supplements such as fish oil or flaxseed to your diet.
The test can potentially help you find the root cause of conditions related to low Omega-3 levels, including those related to heart, joints, eyes, brain, lungs and immune system.
Even if your levels are optimal, it helps confirm the optimal amount of Omega-3 levels and whether you need to cut down on any trans-fats or Omega-6 fatty acids.
The at-home Omega-3 test helps check for potential risks of heart disease, child development during pregnancy, and age related memory decline.
