Why This Biomarker Matters

Elevated alpha-aminobutyrate may indicate metabolic disorders, liver disease, or kidney dysfunction. This helps identify serious metabolic conditions in symptomatic patients.

Overview

Alpha-aminobutyrate (also called 2-aminobutyrate) is a non-standard amino acid produced during protein metabolism. A 24-hour urine test measures excretion levels, which may be elevated in certain metabolic disorders, liver disease, or kidney dysfunction. Abnormal levels are relatively uncommon but may indicate serious metabolic or organ problems. This test is often ordered as part of amino acid profiling in patients with unexplained metabolic symptoms or suspected genetic metabolic disorders.
