Test ID: GALE
UDP-Galactose 4' Epimerase, Blood
Method Description 
Describes how the test is performed and provides a method-specific reference
A buffered enzyme incubation with substrate and cofactors is performed on lysed red blood cells. A postincubation extraction is performed and subjected to liquid chromatography-tandem mass spectrometry (LC-MS/MS). The ratio of the extracted product to its internal standard is used to calculate the total enzymatic product. This is then normalized using the calculated hemoglobin concentration to determine the patient's enzyme level in nmol/h/mg of hemoglobin.(Unpublished Mayo method)

No
Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Friday, 7 a.m. (specimen must be received the day prior)
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
8 days (not reported on Saturday or Sunday)
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result
15 days
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
2 months
Performing Laboratory Location Indicates the location of the laboratory that performs the test
