U1A1 - Performance: UDP-Glucuronosyl Transferase 1A1 TA Repeat Genotype, UGT1A1

Test Catalog

Test Name

Test ID: U1A1    
UDP-Glucuronosyl Transferase 1A1 TA Repeat Genotype, UGT1A1

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

The promoter of UGT1A1 is amplified by PCR. The number of thymine-adenine (TA) repeats is determined in the amplified product by fragment size analysis following capillary electrophoresis.(Baudhuin L, Highsmith WE, Skierka J, et al: Comparison of three methods for genotyping the UGT1A1 TA repeat polymorphism. Clin Biochem 2007:40:710-717)

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.

Monday, Wednesday, Friday; Varies

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.

2 days (Not reported Saturday or Sunday)

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

5 days

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

Whole Blood: 2 weeks Extracted DNA: 2 months

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