Screening for possible oligosaccharidoses


Oligosaccharidoses are characterized by the abnormal accumulation of incompletely degraded oligosaccharides in cells and tissues and the corresponding increase of related free oligosaccharides in the urine.


Clinical features of oligosaccharidoses often overlap; therefore, urine screening is an important tool in the initial workup for these disorders.


Enzyme or molecular analysis is required to make a definitive diagnosis.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
