Background and clinical significance
Quantitative analysis of conventional proteinogenic and nonstandard amino acids is important for the detection and monitoring of patients with inborn errors of metabolism. Additionally, knowledge of amino acid concentrations provides useful information when determining nutritional status following total parenteral nutrition, surgery and shock trauma treatment.
Disease condition
Amino acidopathies, organic acidopathies and other disorders/disturbances that affect amino acid metabolism.
