Advisory Information
Diagnostic specificity of inborn errors of metabolism via urine acylglycine testing is available only for selected inborn errors of metabolism; it is recommended that urine organic acids (OAU / Organic Acids Screen, Urine) be ordered and assessed simultaneously due to the limited number of metabolites included in this urine acylglycine test.

Useful for Diagnosis and monitoring for patients affected with 1 of the following inborn errors of metabolism:
Fatty Acid Oxidation Disorders
-Glutaric acidemia type II
-Medium-chain 3-ketoacyl-CoA thiolase (MCKAT) deficiency
-Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency
-Short chain acyl-CoA dehydrogenase (SCAD) deficiency

Organic Acidurias
-2-Methyl-3-hydroxybutyryl-CoA dehydrogenase (2M3HBD) deficiency
-2-Methylbutyryl-CoA dehydrogenase deficiency
-3-Methylcrotonyl-CoA carboxylase deficiency
-3-Methylglutaconyl-CoA-hydratase deficiency
-Aminoacylase 1 deficiency
-Beta-ketothiolase deficiency
-Ethylmalonic encephalopathy
-Glutaryl-CoA dehydrogenase deficiency
-Isobutyryl-CoA dehydrogenase (IBD) deficiency
-Isovaleryl-CoA dehydrogenase deficiency
-Multiple carboxylase deficiency
-Propionic acidemia
