Medium- to Long-Chain Acylcarnitine Ratio Measurement

**Semantic type:** Laboratory Procedure

**Definition:** The determination of the ratio of medium-chain acylcarnitines (acyl groups with 6 to 12 carbon atoms) to long-chain acylcarnitines (acyl groups with 13 to 20 carbon atoms) present in a sample. The measurement may be expressed as a ratio or percentage.
