Enzyme Screening
The SAS Enzyme Laboratory offers a series of
grouped lysosomal enzyme assays using plasma and white cells to
screen for lysosomal storage disorders.
For patients with neurodegeneration the following
assays are carried out:
Plasma |
White
Cells |
| Hexosaminidase (total) |
Arylsulphatase A |
| Hexosaminidase A |
b-galactosidase |
| b-mannosidase |
Galactocerebrosidase |
| b-glucuronidase |
a-fucosidase |
| a-N-acetylgalactosaminidase |
a-mannosidase |
| Aspartylglucosaminidase |
|
For patients with hepato(spleno)megaly with
or without neurodegeneration the following assays are carried out:
Plasma |
White
Cells |
| b-glucuronidase |
b-glucosidase |
| b-mannosidase |
Sphingomyelinase |
| |
b-galactosidase |
| |
Acid Esterase |
| |
a-fucosidase |
| |
a-mannosidase |
Specimen Reqirements: For a
full screen please send 10 ml lithium heparin whole blood unseparated
and unfrozen. Send at ambient temperature to the laboratory.
THE LABORATORY RECOMMENDS USE OF A COURIER
SERVICE OR ROYAL MAIL SPECIAL DELIVERY FOR SENDING ALL SPECIMENS
TO THE LABORATORY.
Please include brief clinical details. If less than 10 ml blood
is received a complete screen may not be possible.
It may be appropriate to include urine for analysis of oligosaccharides
and glycosaminoglycans
with the blood sample for screening for a lysosomal storage disorders.
