Nonesterified Fatty Acids (Free Fatty Acids) Blood Test
The Nonesterified Fatty Acids (Free Fatty Acids) Blood Test assesses free fatty acid levels, aiding in the diagnosis and management of conditions such as insulin resistance, diabetes, obesity, and metabolic syndrome.
Methodology:
Spectrophotometry
Preparation:
Sample should be collected in the early morning after a 12-hour fast. Blood for the NEFA procedure should be collected after an overnight fast because the level of circulating nonesterified fatty acids is strongly influenced by food ingestion. If the patient has not properly fasted, the determined level of NEFA will be elevated and not directly comparable to a normal range derived from fasting normal controls.
Test Results:
3-6 days. May take longer based on weather, holiday, or lab delays.

What is the purpose of this test?
A Nonesterified Fatty Acids (Free Fatty Acids) Blood Test is a medical test that measures the concentration of free fatty acids in the bloodstream. Free fatty acids are an important source of energy for the body, but high levels of these fatty acids can be a sign of certain metabolic disorders such as insulin resistance, diabetes, and metabolic syndrome.
The test is usually performed by drawing blood from a patient's arm. The blood sample is then sent to a laboratory for analysis. The test measures the amount of nonesterified fatty acids (NEFAs) in the blood, which are fatty acids that are not bound to other molecules, such as proteins. The NEFAs in the blood are usually in equilibrium with the fatty acids stored in adipose tissue. However, when there is an increased demand for energy, the NEFAs are released into the bloodstream for use by the body's cells. Elevated levels of NEFAs in the blood can indicate that the body is experiencing increased lipolysis, which is the breakdown of stored fats.
The Nonesterified Fatty Acids Blood Test is often used to help diagnose and monitor conditions such as insulin resistance, diabetes, and metabolic syndrome. It can also be used to evaluate the effectiveness of certain treatments, such as diet and exercise programs, in managing these conditions. In summary, the Nonesterified Fatty Acids (Free Fatty Acids) Blood Test is a useful diagnostic tool that provides valuable information about a patient's metabolic health. It can help identify underlying health conditions and guide treatment decisions to improve overall health outcomes.
