Flow Injection Analysis-Tandem Mass Spectrometry (FIA-MS/MS)
Evaluation of patients with clinical suspiccion of a wide range of inborn errors of metabolism, especially organic acidemias and fatty acid oxidation disorders including primary carnitine deficiency.
Free Carnitine: 77 - 214 nmol/g creatinine; Total Carnitine: 180 - 412 nmol/g creatinine; Ratio (Acyl to Free): 0.7 - 3.4. Interpretive report provided.
Increased values are obtained after carnitine implementation or meat consumption. It is recommended that plasma concentrations be determined concurrently with urine collection.
