About the test
Essential Fatty Acids (C12-C22), to be used for basic nutritional assessment, identifying fatty acid deficiency, and monitoring patients with fatty acid deficiency who are being treated with a special diet and/or fatty acid supplements.
Included biomarkers & Reference ranges
| Biomarker | Reference range |
|---|---|
| A-Linolenic C18:3W3 Measures alpha-linolenic acid in serum, the plant-based omega-3 fatty acid that comes from foods like flaxseed, walnuts and canola oil. | — |
| Arachidic, C20:0 Measures arachidic acid in serum, a saturated fatty acid found in small amounts in peanuts and some vegetable oils. | — |
| Arachidonic, C20:4W6 Measures arachidonic acid in serum, an omega-6 fatty acid from meat, eggs and dairy that the body uses to make inflammation-related signalling molecules. | — |
| Docosahexaenoic Acid (DHA), C22:6 Omega-3 Measures DHA (C22:6 omega-3), a long-chain omega-3 fatty acid from fish and seafood, in serum as part of a fatty acid panel. | — |
| Docosenoic, C22:1 Measures docosenoic acid (C22:1), a very long-chain monounsaturated fatty acid such as erucic acid, as part of a serum fatty acid panel. | — |
| Docosapentaenoic Acid (DPA), C22:5 Omega-3 Measures omega-3 DPA (C22:5 omega-3), a long-chain fatty acid between EPA and DHA, in serum as part of a fatty acid panel. | — |
| Docosapentaenoic Acid (DPA), C22:5 Omega-6 Measures omega-6 DPA (C22:5 omega-6), a long-chain omega-6 fatty acid, in serum as part of a fatty acid panel looking at fat balance. | — |
| Docosatetraenoic Acid (DTA), C22:4 Omega-6 Measures DTA (adrenic acid, C22:4 omega-6), a long-chain omega-6 fatty acid made from arachidonic acid, in serum as part of a fatty acid panel. | — |
| Eicosapentaenoic Acid (EPA), C20:5 Omega-3 Measures eicosapentaenoic acid (EPA), an omega-3 fatty acid, in serum to help assess your omega-3 intake and overall fatty acid balance. | — |
| Fatty Acids, Total The total amount of fatty acids measured in your serum, used as the reference point for interpreting the individual fatty acids in the panel. | — |
| G Linolenic, C18:3W6 Measures gamma-linolenic acid (GLA), an omega-6 fatty acid, in serum to help assess omega-6 metabolism and overall fatty acid balance. | — |
| H G Linolenic, C20:3W6 Dihomo-gamma-linolenic acid, an omega-6 fatty acid measured in serum fatty acid panels to look at essential fatty acid balance and omega-6 metabolism. | — |
| Hexadecenoic C16:1W9 A 16-carbon omega-9 monounsaturated fatty acid measured in serum as part of fatty acid panels that look at dietary fat intake and fat metabolism. | — |
| Lauric, C12:0 A 12-carbon saturated fatty acid found in coconut and palm kernel oil, measured in serum fatty acid panels to look at diet and fat metabolism. | — |
| Linoleic C18:2W6 Linoleic acid (C18:2 omega-6), the main omega-6 essential fatty acid, measured in serum fatty acid panels to look at your essential fatty acid status. | — |
| Mead Acid/Arachidon Ratio A ratio calculated from Mead acid and arachidonic acid in serum, used as a marker of essential fatty acid status. | — |
| Mead, C20:3W9 Measures Mead acid, an omega-9 fatty acid your body makes when essential fatty acids are scarce, to help assess essential fatty acid status. | — |
| Monounsaturated, Total The combined serum level of monounsaturated fatty acids, such as oleic acid, giving an overview of this fat group in your blood. | — |
| Myristic, C14:0 Measures myristic acid, a saturated fatty acid found in dairy fat and coconut and palm kernel oils, as part of a serum fatty acid profile. | — |
| Nervonic, C24:1W9 Measures nervonic acid, a long-chain omega-9 fatty acid that is an important building block of nerve tissue, in serum. | — |
| Oleic, C18:1W9 Measures oleic acid, the main monounsaturated omega-9 fatty acid found in olive oil and many other fats, in serum. | — |
| Palmitic, C16:0 Measures palmitic acid, the most common saturated fatty acid in the body and diet, as part of a serum fatty acid profile. | — |
| Palmitoleic, C16:1W7 Measures palmitoleic acid, an omega-7 monounsaturated fatty acid made mainly in the body, as part of a serum fatty acid profile. | — |
| Polyunsaturated, Total The combined level of polyunsaturated fatty acids, including omega-3 and omega-6 fats, in your blood, calculated from the individual fatty acids measured. | — |
| Saturated, Total The combined level of saturated fatty acids in your blood, calculated from the individual saturated fatty acids measured on the panel. | — |
| Stearic, C18:0 Measures stearic acid, an 18-carbon saturated fatty acid in your blood, as part of a fatty acid profile looking at diet and fat metabolism. | — |
| Total W3 The sum of the omega-3 fatty acids measured in your blood, such as EPA and DHA, used to look at your overall omega-3 status. | — |
| Total W6 The sum of the omega-6 fatty acids measured in your blood, such as linoleic and arachidonic acid, used to look at your omega-6 status. | — |
| Vaccenic, C18:1W7 Measures vaccenic acid, an omega-7 monounsaturated fatty acid found in dairy and ruminant fats, as part of a fatty acid profile. | — |

Preparation
- Do not consume alcohol for 24 hours prior to sample collection.
- Overnight fasting is required.
- Fasting before a blood draw means you don't eat or drink anything except water.
- Your doctor should provide any special instructions related to fasting for your test. Always follow your doctor's instructions.
