Nonesterified Fatty Acid Test - More Information

The free fatty acid test, also known as a 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. Measurement of nonesterified fatty acids are helpful in assessing fat breakdown (lipolysis) and fatty acid oxidation in the body. The free fatty acid test is often used in evaluating people who have low blood sugar (hypoglycemia) episodes as well as 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.
