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) or Fabry disease

 

Evidence of ceramide trihexoside accumulation suggests decreased or deficient alpha-galactosidase activity. Follow-up testing with the specific enzyme assay is recommended: AGA / Alpha-Galactosidase, Leukocytes and AGAS / Alpha-Galactosidase, Serum.

 

Evidence of sulfatide accumulation suggests decreased or deficient arylsulfatase A activity. Follow-up testing with the specific enzyme assay is recommended: ARSAW / Arylsulfatase A, Leukocytes; ARST / Arylsulfatase A, Fibroblasts; and ARSU / Arylsulfatase A, 24 Hour, Urine.

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
