Technical Information
Test Procedure: Help
One dried blood spot sample (DBS) is incubated with a mix of substrate and internal standard (IS) for iduronate 2-sulfatase, heparan N-sulfatase, alpha-N-acetylglucosaminidase, N-acetylgalactosamine-sulfate, beta-galactosidase, arylsulfatase B, beta-glucuronidase, and tripeptidyl peptidase 1. A second DBS sample is incubated with a mix of substrate and IS for acetyl-CoA:alpha-glucosaminide N-acetyltransferase; and a … View more

Entire test performed in-house
Analytical Validity: Help
Accuracy was assessed by analysis of normal and deficient specimens (N=170); all samples were clinically concordant. Intra assay precision was performed at 3 levels: CV results ranged from 4% to 20% (N=20 each). Inter assay precision was performed at 3 levels: CV results ranged from 6% to 18% (N=30 each). … View more
Assay limitations: Help
Beta-galactosidase is reduced in patients with galactosialidosis. Those patients will also demonstrate deficient activity of neuraminidase which is not evaluated on this panel. If there is clinical suspicion of galactosialidosis, order test OLIGU / Oligosaccharide Screen, Random, Urine. Mucolipidosis II (MLII, I-cell disease) may not be detectable by this assay. … View more
