Test Catalog

Test Name

Test ID: MPSBS    
Mucopolysaccharidosis, Blood Spot

Useful For Suggests clinical disorders or settings where the test may be helpful

Quantification of heparan sulfate and dermatan sulfate in dried blood spots can support the biochemical diagnosis of one of the mucopolysaccharidoses types I, II, III, or VI

Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request

This test is used as a second-tier newborn screen for mucopolysaccharidosis (MPS) types I and II and to aid in the diagnosis and monitoring of patients with MPS types I, II, III, and VI.

Highlights

Accumulation of undegraded GAGs leads to progressive cellular dysfunction and results in the typical clinical features seen with this group of disorders.

 

Dermatan sulfate (DS) and heparan sulfate (HS) are markers for a subset of mucopolysaccharidoses (MPS).

 

Testing for DS and HS in dried blood spots can aid in the diagnosis of MPS types I, II, III, and VI.
