Polyunsaturated, Total details
What Polyunsaturated, Total shows
Total polyunsaturated fatty acids is a calculated value: the sum of the individual polyunsaturated fatty acids measured in your serum, such as omega-3 fats like EPA and DHA and omega-6 fats like linoleic and arachidonic acid. Your body cannot make some of these, so they come from foods such as vegetable oils, nuts, seeds and fish. The total helps give an overall picture of your fatty acid status and dietary fat pattern. A lower total can reflect low intake or poor fat absorption, while a higher total usually reflects diet. It is most useful alongside the individual fatty acids and their ratios.
Tests that include Polyunsaturated, Total
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.
