Test Code UHiRsOlig High Resolution Oligosaccharides, Urine

Clinical System Name

High Resolution Oligosaccharides, Urine


Urine High Resolution Oligosaccharides


This urinary oligosaccharide and glycan screening is using MALDI-TOF/TOF technology, which provides a better sensitivity and specificity than the traditional TLC method. Different from the traditional TLC method, this method successfully detects subtle excretions of abnormal oligosaccharides in mucolipidosis II and III ( I cell disease) as well as other oligosaccharidoses. Conditions screened for are the following: Fucosidosis, Alpha-mannosidosis, Beta-mannosidosis, Sialidosis, Aspartylglucosaminuria, Schindler disease, Kanzaki disease, Mucolipidosis II and III ( I cell disease), Galactosialidosis, CDGIIb, Pompe disease, and Tay Sachs / Sandhoff (GM2).
