Test ID: IDST
Alpha-L-Iduronidase, Fibroblasts
Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Useful For Suggests clinical disorders or settings where the test may be helpful
Diagnosis of mucopolysaccharidosis I (MPS I), Hurler syndrome (MPS IH), MPS IS (Scheie syndrome (MPS IS), and Hurler-Scheie syndrome (MPS IH/S)
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
Diagnostic testing. Not recommended for carrier detection.
Fibroblasts are the preferred specimen since testing for other mucopolysaccharide storage diseases may be necessary.
Additional Tests Lists test(s) that are always performed, at an additional charge, with the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| FIBR | Fibroblast Culture | Yes | Yes |
| CRYOB | Cryopreserve for Biochem Studies | No | Yes |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
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.
