Additional Information

Useful For	Screening of mucopolysaccharide disorders (MPS). Testing includes low voltage electrophoresis in two dimensions on cellulose acetate sheets followed by a staining process with Alcian Blue. Mucopolysaccharidoses (MPS) are a group of inherited diseases which are characterized by a progressive accumulation of partially degraded glycosaminoglycans (GAGs) in the lysosomes.
Clinical Indication	skeletal deformities hepatomegaly Hernia learning difficulties behavioural disturbance and severe bone dysplasia
Interpretation	Interpretation is based on the overall pattern of the electrophoresis profile. Diagnosis would need to be confirmed by enzyme or DNA analysis.

For URGENT analysis, contact the Biochemical Genetics laboratory at 6394 8728 or the Lead Scientist at 8388 8741 to discuss.

If sent after office hours, urine will be stored in Clinical Laboratory -20°C freezer.
