This test measures a panel of lysosomal enzymes for investigating a number of lysosomal storage disorders (but note not all LSDs are investigated with this panel). The following disorders are investigated in the panel: Sandhoff disease, I-cell disease, Beta-Mannosidosis, Tay-Sachs disease, Aspartylglucosaminuria, Sly disease (MPS VI), GM1-gangliosidosis, Alpha-Mannosidosis, Fabry disease, Fucosidosis, Wolman/cholesterol ester storage disease, Metachromatic Leucodystrophy, Gaucher disease, Niemann-Pick types A & B, Krabbe Leucodystrophy, Schindler disease. Please note: If individual disorders are being considered, please write the name of the disorder you wish to investigate. If advice is not available locally then the paediatric metabolic consultant on call at the Willink can be contacted through their hospital switchboard on 0161 276 1234. Ask for the paediatric metabolic consultant on call. Please try and collect at least 5 mL EDTA blood for this test. Smaller volumes of blood cause poor quality results and are likely to need a repeat sample. Samples with less than 3 mL of blood are insufficient for analysis and will not be sent.
