Test ID: HEX4    
Glucotetrasaccharides, Random, Urine

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

A random urine sample is corrected per creatinine content. The creatinine-corrected urine is combined with ammonium hydroxide and internal standard in a 96-well filter plate. After centrifugation, an aliquot of the eluate is injected onto an amide column and analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in negative mode. The ratio of the extracted peak area for glucotetrasaccharide to the internal standard is used to calculate the concentration of glucotetrasaccharide present.(Unpublished Mayo method)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.

Wednesday; 11 a.m.

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.

7 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

14 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
