Synonyms Acyl-glycine; MCAD; Medium chain acyl-coenzyme a dehydrogenase deficiency; Medium chain fatty acid oxidation defect; Hexanoylglycine; Phenylpropionylglycine; Suberylglycine
Turn around times Test performed weekly. Turnaround time: 2-9 days.
Additional information For possible fatty acid oxidation abnormalities due to a mutation of acylcoenzyme A dehydrogenase but undetected by urinary organic acid analysis. Elevation of hexanoyl- and phenylpropionylglycine is characteristic of deficient activity of medium-chain acylcoenzyme A dehydrogenase.
CPT coding 82544-90
