|---|---|
| Approval req'd? | No |
| Available Stat? | No |
| Utilization Guidelines | This test should be ordered in conjunction with the TLC assay (MPSTLC) when establishing or confirming a diagnosis of mucoplysacharidoses. Once the diagnosis and type of mucoplysaccharidoses is established in a given patient monitoring typically only requires the quantitative assay be performed. |
