Description
The OmegaCheck test measures the levels of omega-3 fatty acids in the blood to provide insight into cardiovascular health, inflammation, and overall fatty acid balance. It is commonly used to evaluate dietary intake of omega-3s (like EPA and DHA from fish oil) and to assess whether supplementation is needed.
How the Test Works
- A small blood sample is collected and analyzed to determine the percentages of EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and total omega-3 fatty acids in red blood cell membranes.
- The test may also calculate an Omega-3 Index, which is the combined percentage of EPA and DHA relative to total fatty acids.
Purpose of the Test
- Cardiovascular risk assessment: Higher omega-3 levels are associated with lower risk of heart disease.
- Inflammation monitoring: Omega-3s have anti-inflammatory effects, and low levels may correlate with increased inflammation.
- Supplementation guidance: Helps determine whether fish oil or other omega-3 supplements are necessary and if dosing is adequate.
- Nutritional evaluation: Provides objective information about dietary omega-3 intake.
When to Test
- Individuals with heart disease risk factors
- Patients considering or taking omega-3 supplements
- Those with inflammatory conditions such as arthritis
- Individuals who want to assess overall nutritional status
Fasting
- Fasting is not required.
The OmegaCheck test offers a practical and actionable view of omega-3 status, helping guide personalized nutrition and supplementation strategies.
