Why the Test is Performed Return to top
This test is done to measure amino acid levels in the urine. There are many different types of amino acids. It is common for some of each kind to be found in the urine, but increased levels of individual amino acids can be a sign of an inborn error of metabolism.Screening infants for increased levels of amino acids can lead to early diagnosis of an inborn error of metabolism. If the condition is promptly treated, complications such as severe mental retardation may be prevented.
