Test Details
Methodology
Glucocerebrosidase (leukocyte) is measured by fluorometric enzyme assay using 4-methylumbelliferyl-beta-D-glucosida as substrate, with/without glucocerebrosidase-specific inhibitor.
Result Turnaround Time
3 - 13 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Gaucher disease occurs at an increased frequency in individuals of Ashkenazi Jewish descent, with a carrier frequency of approximately 1 in 15. It is a lysosomal storage disorder with variable severity that, if untreated, may result in anemia, hepatosplenomegaly, nosebleeds, and fractures. In the more severe and rare form, the brain and nervous system are involved. Enzyme analysis is performed in individuals suspected of having the disease, who may need enzyme replacement therapy.
Special Instructions
Specimens must arrive at testing laboratory within four days of collection. Collect Monday through Wednesday only. While enzyme testing is offered as a standalone test, it is strongly recommended that clients opt for both DNA and enzyme testing.
Specimen Requirements
Specimen
Whole blood
Volume
10 mL
Container
Adult: Two 10-mL lavender-top (EDTA) tubes. Pediatric: One lavender-top (EDTA) tube.
Storage Instructions
Refrigerate after collection. Transport to the testing laboratory using cool packs. Do not allow the sample to freeze. Time-sensitive; specimens must be received within four days of collection; please collect/ship Monday through Thursday only.
