Why This Biomarker Matters

Abnormal urine serine levels may indicate inherited metabolic disorders or kidney dysfunction. This test is particularly important in newborn screening for serious metabolic conditions.

Understanding Your Results

Normal Range

0.3 – 1.2 nmol/mL

Overview

Serine is a non-essential amino acid that your body synthesizes from other compounds and also obtains from food. A urine serine test measures how much of this amino acid is being excreted in your urine, reflecting your body's amino acid metabolism and nutritional status. Abnormal serine levels may indicate genetic metabolic disorders, kidney dysfunction, or nutritional imbalances. This test is most commonly used in newborn screening and evaluation of suspected inherited metabolic diseases.
