Testing for Gaucher Disease
Gaucher Disease can be diagnosed early through a blood test. Carrier status can be detected through blood or saliva. There are Gaucher specialists throughout the country who can diagnose, evaluate and recommend proper treatment. The testing process can be done at a hospital, Gaucher specialist's office, or through your family physician. Your physician can draw blood that would then be sent to a specific laboratory for testing.
The NGF is committed to keeping the public informed about all aspects of Gaucher Disease including treatment options, testing and services available for Gaucher patients, physicians and treatment providers. For your convenience, the NGF has provided a diagnostic lab list and other testing websites to assist you and your physician find Diagnostic and Gaucher testing labs throughout the country.

Testing For Gaucher disease
An enzyme assay test measures glucocerebrosidase (GC) activity in leukocytes, fibroblasts, or urine. Individuals who are affected with Gaucher Disease will have very low levels of enzyme activity. There are four common mutations of the GC gene: N370S, L444P, 84gg and IVS2[+1]. DNA analysis for these four mutations detects 90% to 95% of the mutations associated with Gaucher Disease in the Ashkenazi Jewish population, and 50% to 75% of the associated mutations in the general population. Neither disease type nor severity of disease is defined by enzyme assay. DNA analysis is used in combination with the enzyme assay test to diagnose Gaucher Disease and is helpful in defining the subtype.
Approximately 1 in 60,000 people have Gaucher Disease. However, among Jews of Eastern European (Ashkenazi) descent, one in 450 people will have the disorder, and the carrier rate is approximately 1 in 15. Carrier status can be detected through a blood or saliva test. The testing process can be done at a hospital, Gaucher specialist's office, or through your family physician. Laboratory assay tests use chromosomes, DNA, RNA, and genes to determine the genetic status of a person who is at high risk for a particular condition.
