Reference Range Information
0-4 months: < or =53.0 mg/mmol creatinine
5-18 months: < or =31.0 mg/mmol creatinine
19 months-2 years: < or =24.0 mg/mmol creatinine  
3-5 years: < or =16.0 mg/mmol creatinine

>14 years: < or =6.5 mg/mmol creatinine
Interpretation
​An abnormally elevated excretion of glycosaminoglycan (GAG) is characteristic of mucopolysaccharidoses. GAG levels may normalize or remain elevated in patients who have undergone bone marrow transplants or are receiving enzyme replacement therapy.
