Free Fatty Acid Blood Test - More Information
The free fatty acid test, also known as a free fatty acid blood test, NEFA blood test and a nonesterified fatty acid lab test, measures the free fatty acid blood level.
Fatty acids are molecules that typically consist of complex molecules made of carbon and hydrogen. Fatty acids are important in humans because they are major stores of energy and are important for energy production. When fatty acids are not esterified (i.e. in the glyceride state), they are considered to be bioavailable, or free, to be used for metabolic needs.
Free fatty acid levels are useful for assessing fatty acid oxidation in patients. Elevated fatty acid levels are associated with abnormal blood glucose control and poor lipolysis. Measurement of nonesterified fatty acids are also helpful in assessing fat breakdown (lipolysis) in the body. The free fatty acid test is often used in evaluating people to get a baseline nutritional evaluation.
To get a free fatty acid test near you at a Quest Diagnostics lab, order online and get your blood drawn at the selected lab. As can be seen on the sample nonesterified fatty acid report, the free fatty acid blood level is reported in mmol/L and can be compared against the reference range provided by the lab.
