| name | N-Acetylgalactosamine-4-Sulfatase/N-Acetylgalactosamine-6-Sulfatase [Enzymatic activity ratio] in Urine | ||
| description | The ratio of N-acetylgalactosamine 4-sulfatase to N-acetylgalactosamine 6-sulfatase helps differentiate between Morquio A syndrome and Maroteaux-Lamy syndrome. Morquio A syndrome (mucopolysaccharidosis type IVA) is associated with a deficiency of N-acetylgalactosamine 6-sulfatase, while Maroteaux-Lamy syndrome (mucopolysaccharidosis VI), is associated with a loss or decreased activity of N-acetylgalactosamine 4-sulfatase. | ||

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
