Test Catalog

Test ID: GAL1P    
Galactose-1-Phosphate, Erythrocytes

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

Packed RBCs are diluted with cold water and vortexed to lyse the cells, creating a hemolysate. The hemolysate is extracted with acetonitrile/methanol containing internal standard and then is centrifuged prior to injection onto a liquid chromatography-tandem mass spectrometry (LC-MS/MS) system. The ratio of the extracted peak area of Gal-1-P to its internal standard (13)C2-Gal-1-P as determined by LC-MS/MS is used to calculate the concentration of analyte, in mg/dL, in the sample.(Unpublished Mayo method)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.


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.

8 to 15 days

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

1 month

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