This urine test panel measures 36 amino acids, the building blocks of proteins and key metabolic intermediates. Measuring amino acids in urine can help detect inherited metabolic disorders such as aminoacidurias, assess kidney reabsorption problems, and investigate unexplained symptoms. The panel is often used to screen for or monitor conditions in which amino acids appear in abnormal amounts. Results are interpreted by a specialist together with blood testing, clinical findings, and other metabolic studies.

• Alanine An amino acid involved in glucose and energy metabolism.
• Alpha-Aminoadipic Acid A metabolite in the lysine breakdown pathway.
• Alpha-Aminobutyric Acid A marker that can reflect amino acid metabolism.
• Arginine An amino acid involved in the urea cycle and nitric oxide production.
• Asparagine An amino acid important in protein synthesis and nitrogen handling.
• Aspartic Acid An amino acid involved in the urea cycle and energy metabolism.
• Beta-Alanine A metabolite related to the breakdown of pyrimidines and certain amino acids.
• Beta-Aminoisobutyric Acid A breakdown product of thymine and valine metabolism.
• Carnosine A dipeptide of beta-alanine and histidine found in muscle and brain.
• Citrulline An intermediate in the urea cycle that reflects nitrogen processing.
• Cystathionine An intermediate in the transsulfuration pathway of methionine metabolism.
• Cystine A form of cysteine that can indicate sulfur amino acid handling.
• Ethanolamine A compound related to phospholipid metabolism.
• Glutamic Acid An amino acid central to nitrogen metabolism and neurotransmission.
• Glutamine The most abundant amino acid and a key nitrogen carrier.
• Glycine A small amino acid involved in protein synthesis and detoxification.
• Histidine An essential amino acid and precursor to histamine.
• Homocystine A form of homocysteine measured to assess sulfur amino acid metabolism.
• Hydroxyproline A marker related to collagen turnover.
• Isoleucine A branched-chain amino acid used in energy and protein metabolism.
• Leucine A branched-chain amino acid important for protein synthesis.
• Lysine An essential amino acid needed for protein and carnitine synthesis.
• Methionine An essential amino acid and methyl-group donor.
• 1-Methylhistidine A marker related to histidine metabolism and muscle turnover.
• 3-Methylhistidine A marker of muscle protein breakdown.
• Ornithine An amino acid in the urea cycle.
• Phenylalanine An essential amino acid that is converted to tyrosine.
• Phosphoethanolamine A compound related to phospholipid metabolism.
• Proline An amino acid important in collagen and protein structure.
• Sarcosine A metabolite related to glycine metabolism.
• Serine An amino acid involved in one-carbon metabolism and protein synthesis.
• Taurine A sulfur-containing compound involved in bile and cellular function.
• Threonine An essential amino acid used in protein synthesis.
• Tryptophan An essential amino acid and precursor to serotonin and niacin.
• Tyrosine An amino acid precursor to thyroid hormone and catecholamines.
• Valine A branched-chain amino acid used in energy and protein metabolism.

• People with symptoms that may indicate a metabolic disorder
• Individuals with a family history of amino acid disorders
• Patients being evaluated for kidney reabsorption problems
• People with unexplained developmental or growth concerns
• Patients being monitored for a known aminoaciduria

• A timed or first-morning urine collection may be requested; follow the instructions
• Avoid unusual protein intake before collection
• Report all medications and supplements
• Use the container provided and keep the sample as directed

Increased or unusual amino acids in urine can indicate an inherited metabolic disorder, a kidney reabsorption problem, or a dietary or medication effect. Specific patterns, such as elevated phenylalanine or cystine, help guide interpretation, but the results are complex and are reviewed by a specialist with blood tests and clinical findings. Discuss your urine amino acid profile with a healthcare provider.
