Catalog ID OLIGU Oligosaccharide Screen, Random, Urine
Useful For
Screening for selected oligosaccharidosis
Specimen Type
UrineOrdering Guidance
This is the recommended test when clinical features are suggestive of, or when molecular testing results suggest, an oligosaccharidosis disorder that can be identified by this test.
The recommended screening test for the initial workup of a suspected lysosomal storage disorder, particularly when clinical features are nonspecific, is LSDS / Lysosomal Storage Disorders Screen, Random, Urine.
Necessary Information
1. Patient's age is required.
