| Use: | This biochemical test is a quantitative measurement of iduronate-2-sulfatase enzyme activity and can be used as a 1st tier test for patients with a clinical suspicion of Mucopolysaccharidosis II (MPS II) Hunter Syndrome.
Demonstration of deficient iduronate-2-sulfatase enzyme activity is considered the gold standard to confirm a diagnosis of Mucopolysaccharidosis II (MPS II) Hunter Syndrome. |
