Intended Use

For the quantitative in vitro determination of Non Esterified Fatty Acids (NEFA) in serum and plasma. This product is suitable for both manual and automated use.


Clinical Significance

Non-esterified fatty acids (NEFA) are molecules released from triglycerides by the action of the enzyme lipase and are transported in the blood bound to albumin. They contribute only a small proportion of the body’s fat; however provide a large part of the body’s energy. Measurement of NEFA is important in diabetes where insulin deficiency results in the metabolism of fat. Levels are also frequently increased in obese patients. The level of NEFA is very dependant on the momentary metabolic situation therefore samples should be taken from a relaxed patient following a 12 hour fasting period.

Normal levels of NEFA in the blood should be between 0.1 – 0.9 mmol/l. Elevated levels are often associated with both type II diabetes and obesity making NEFA ideal in monitoring diabetes and its common complications. An increase in NEFA concentration has also been associated with adiposity, malignant disease and other metabolic syndromes.
