Unit Code 80945:
Iduronate Sulfatase, Fibroblasts
Useful For
Diagnosis of Hunter syndrome
Testing Algorithm
When this test is ordered, a fibroblast culture and cryopreservation for
biochemical studies will always be performed at an additional charge.
However, for multiple lysosomal enzyme assays on a patient utilizing
fibroblast culture, only 1 culture is required regardless of the number
of enzyme assays ordered. If viable cells are not obtained within
10 days, client will be notified.
