Quantitative Urine Amino Acids Test - Quantitative Urine Amino Acids Analysis

Quantitative liquid chromatography (HPLC or LC-MS/MS) is used to measure the specific concentration of a large number of free amino acids in a urine sample. It reveals impaired renal tubular reabsorption of amino acids (aminouria) and other amino acid metabolism disorders characterized by increased excretion of specific amino acids.
