Test Indications:  Follow-up of known patient with CDG. Developmentally delayed
 
THIS TEST IS NOT SUITABLE FOR ALCOHOL CONSUMPTION.
 
The congenital disorders of glycosylation (CDG) are a rapidly expanding group of metabolic syndromes with a wide spectrum of symptoms and severity. CDG type I is associated with disruption in the synthesis of the lipid-linked oligosaccharide precursor whereas CDG type II is linked to the malfunctioning trimming/processing of the protein-bound oligosaccharide.
 
This test is qualitative only. This test can NOT pick up rare forms of glycosylation disorders.
