Preferred screening test for mucopolysaccharidoses
Preferred test to screen for mucopolysaccharidosis (MPS). Testing includes both quantitative MPS analysis and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis.
The urine mucopolysaccharides (MPS) screen is the preferred first-line screening test that provides quantitative analysis of total glycosaminoglycans (GAGs) and qualitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of the specific sulfates that are associated with at least 13 different diseases.
An abnormal total GAG value may be obtained on a specimen that yields a normal LC-MS/MS pattern, and this artifact can occur when a patient is treated with low-molecular-weight heparin.
