Test Catalog

Test ID: GALCW    
Galactocerebrosidase, Leukocytes

Method Description Describes how the test is performed and provides a method-specific reference

The specimens are incubated with a mix of substrate and internal standard for galactocerebrosidase (GALC) and alpha-galactosidase (GLA). The reaction is then stopped using acetonitrile, centrifuged, and a portion of the supernatant is prepared for analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS). GLA is included to verify sample integrity.(Unpublished Mayo method)

Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Preanalytical processing occurs Monday through Saturday.

Testing performed: Monday, Wednesday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

5 to 10 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

WBC homogenate: 1 month

Performing Laboratory Location Indicates the location of the laboratory that performs the test
