Suspect Gaucher Disease? Test to Know

  • β-glucosidase enzyme assay is the standard, recommended method for establishing a confirmatory diagnosis of Gaucher disease, which is demonstrated by deficiency of β-glucosidase activity.1,2,3
  • Molecular testing (DNA testing) can be used to confirm the type of Gaucher disease as well as carrier status.1,2

The following testing methods are typically not necessary for diagnosis

  • Demonstration of two pathogenic alleles in the GBA gene can provide additional diagnostic confirmation, but is not generally used for diagnosis in lieu of biochemical testing.2
  • A bone marrow biopsy is not recommended to diagnose Gaucher disease because although bone marrow biopsy specimens can rule out hematologic malignancies, they are not reliable for establishing the presence of Gaucher cells.1
