OmegaCheck

Performed by: Quest Diagnostics

Biomarkers included in this panel:

Arachidonic Acid

Arachidonic acid is an inflammatory omega-6 fatty acid. Our bodies produce this nutrient, and its excess may lead to inflammatory diseases and mood disorders.

Arachidonic Acid/EPA Ratio

This test measures the ratio of arachidonic acid (AA) to eicosapentaenoic acid (EPA) in plasma. This ratio of the principle omega-3 and omega-6 fatty acids is a measure of the body’s eicosanoid balance. Balancing these eicosanoids in the body i

DHA

Docosahexaenoic acid (DHA) is one of the omega-3 fatty acids. Omega-3 fatty acids (omega-3s) have a carbon–carbon double bond located three carbons from the methyl end of the chain. Omega-3s, sometimes referred to as “n-3s,” are

DPA

Docosapentaenoic acid (DPA) is an omega-3 fatty acid with 22 carbons and five double bonds (22:5n3). It is formed from its precursor, EPA, by way of the elongase enzyme which adds two carbons. It can be supplemented or obtained in the diet from foods

EPA

Eicosapentaenoic Acid (EPA) is a Polyunsaturated Omega-3 Fatty Acid and is involved in the regulation of inflammatory processes and prevention of blood clots. Omega-3 fatty acids (omega-3s) have a carbon–carbon double bond located three carb

EPA+DPA+DHA

Three of the most important omega-3 fatty acids are eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA). Omega-3 fatty acids are primarily obtained from food sources, such as oily fish. They have antioxidant,

Linoleic Acid

Linoleic acid is by far the most abundant polyunsaturated fatty acid in most human tissues. Linoleic acid is an essential fatty acid, and low levels indicate dietary insufficiency.

Omega-3 total

Essential fatty acids are classified into fat "families": omega 3 fats and omega 6 fats. Non-essential fat "families" include omega-9 fats, saturated fats, omega-7 fats, and trans-fats. Optimal health depends on the proper b

Omega-6 total

The laboratory does not provide a specific reference range for this marker. Please refer to the Omega-6/Omega-3 Ratio for detailed information and interpretive guidance. This ratio is essential for assessing various health markers related to fatty ac

Omega-6/Omega-3 Ratio

Omega-6:Omega-3 ratio is calculated by dividing the sum of all the omega-6 fatty acids by the sum of all the omega-3 fatty acids. Omega 6 and 3 are two essential fats that are categorized as polyunsaturated fatty acids, or PUFAs for shor

OmegaCheck

This marker determines fatty acid-associated risk for cardiovascular events. OmegaCheck = [(EPA + DPA + DHA) ÷ total PLFA] x 100 Diet is a modifiable risk factor for cardiovascular disease. For example, diets rich in polyunsaturated fatt
