Unit Code 81979:
Ceramide Trihexoside/Sulfatide Accumulation in Urine Sediment, Urine
Useful For 
Suggests clinical disorders or settings where the test may be helpful
As an aid in identifying patients with Fabry disease or determining
carrier status for Fabry disease
As an aid in identifying patients with metachromatic leukodystrophy.
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
Identifying patients with metachromatic leukodystrophy (MLD),
Fabry disease, or determining carrier status for Fabry disease.
Evidence of ceramide trihexoside accumulation suggests decreased
or deficient alpha-galactosidase activity. Follow-up testing with the
specific enzyme assay is recommended: #8785 "Alpha-
Galactosidase, Leukocytes" and #8784 "Alpha-Galactosidase, Serum.
Evidence of sulfatide accumulation suggests decreased or deficient
arylsulfatase A activity. Follow-up testing with the specific enzyme assay
is recommended: #8779 "Arylsulfatase A, Leukocytes"; #8778
"Arylsulfatase A, Fibroblasts"; and #8777 "Arylsulfatase A, Urine."
