Docosapentaenoic Acid (DPA), C22:5 Omega-3 details
What Docosapentaenoic Acid (DPA), C22:5 Omega-3 shows
Docosapentaenoic acid, or DPA, comes in an omega-3 and an omega-6 form, and this result is the omega-3 form. It is found in oily fish, seafood and some meats, and the body also makes it from EPA and can convert it toward DHA. This test measures omega-3 DPA in serum as part of a fatty acid panel. A lower level generally reflects lower intake of omega-3-rich foods, and a higher level greater intake. It is interpreted alongside EPA, DHA and the omega-6 fatty acids to give a picture of your overall omega-3 status.
Tests that include Docosapentaenoic Acid (DPA), C22:5 Omega-3
Comprehensive Fatty Acids (C8-C26), to evaluate patients for certain mitochondrial fatty acid oxidation defects, peroxisomal defects, and/or a full nutritional assessment. It can also be used to monitor patients receiving a special diet and/or fatty acid supplementation.
