Carnitine Panel
Also known as: CARNPAN
Use
The Carnitine Panel is used to diagnose and monitor fatty acid oxidation disorders and organic acidemias. It is recommended to be used in conjunction with urine organic acids and acylglycines testing for a comprehensive evaluation. This panel helps in detecting abnormalities in carnitine levels that are indicative of metabolic conditions.
Special Instructions
Clinical information such as age, gender, diet (including TPN therapy), drug therapy, and family history is necessary for appropriate interpretation. The Biochemical Genetic Testing Patient History Form must be submitted with the order and is available on the ARUP website.
Limitations
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the FDA and is intended for clinical use in a CLIA-certified laboratory. The esterified carnitine concentration is derived from a mathematical calculation using free and total carnitine levels, which may introduce variability in certain clinical situations.
