Rejection Criteria:
Specimens containing preservatives.
Turn Around Time:
4-14 days upon receipt at reference laboratory
Reference Range:
Electrophoresis Pattern By report Quantitative, Urine 0-5 months: 14.6-47.8 mg/mmol creatinine 6-11 months: 3.7-35.5 mg/mmol creatinine 1-2 years: 5.4-30.8 mg/mmol creatinine 3-6 years: 5.2-16.7 mg/mmol creatinine 7-13 years: 2.4-10.2 mg/mmol creatinine 14 years or older: 0.0-7.1 mg/mmol creatinine
Interpretive Data:
Mucopolysaccharides (Glycosaminoglycans) include: Keratan Sulfate, Heparan Sulfate, Dermatan Sulfate, and Chondroitin Sulfates 4 and 6. The excretion of Heparan Sulfate is variable. A normal mucopoly- saccharides screen does not exclude Sanfilippo Syndrome (Mucopolysaccharidosis Type III).
Comments:
The Patient History for Mucopolysaccharides (MPS) Testing form from ARUP Laboratories needs to be filled out and accompnay the sample.
