Why This Biomarker Matters
Abnormal asparagine levels can identify rare genetic metabolic disorders or kidney dysfunction requiring specialized diagnosis and treatment.
Overview
Asparagine is an amino acid important for protein synthesis and cellular function. Urine asparagine levels reflect your body's amino acid metabolism and kidney function. Abnormal asparagine levels may indicate genetic metabolic disorders affecting amino acid processing, kidney disease, or nutritional imbalances. This test is typically ordered when investigating unexplained developmental delays, seizures, or when rare metabolic disorders are suspected.
