Decadienoylcarnitine, Substance Concentration, Serum or Plasma
This test measures the amount of a specific acylcarnitine, decadienoylcarnitine, in serum or plasma using a substance concentration measurement. It is typically part of specialized biochemical testing of fatty acid and energy metabolism.

What Is Being Measured
Decadienoylcarnitine is a specific acylcarnitine, a molecule formed when carnitine binds to a fatty acid byproduct during fat metabolism. Measuring its concentration in serum or plasma can help evaluate how the body processes certain fatty acids.
Why This Test May Be Ordered
Specialized acylcarnitine testing is often used in the evaluation of metabolic conditions, particularly when a healthcare provider suspects a disorder of fatty acid oxidation or related energy metabolism. This specific analyte would usually be interpreted together with a broader acylcarnitine profile rather than on its own.
How the Sample Is Collected
A blood sample is collected, typically from a vein in the arm, and serum or plasma is separated for analysis. No special preparation is usually described for this type of measurement, but follow any instructions given by the ordering laboratory.
Interpreting Results
Results are interpreted by a healthcare professional in the context of the full acylcarnitine profile, symptoms, age, diet, and other laboratory findings. Results for a single acylcarnitine are not usually meaningful without this broader context, and numeric reference ranges vary by laboratory.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Acylcarnitine measurements such as decadienoylcarnitine can support the evaluation of fatty acid oxidation disorders and other metabolic conditions. Because interpretation depends on the complete profile and clinical picture, results should be reviewed by a qualified healthcare provider rather than interpreted in isolation.
