Test ID: TAPEN    
Tapentadol and Metabolite, Urine

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

Isotopically labeled tapentadol is added to the sample as an internal standard. Ammonium acetate buffer and beta-glucuronidase is then added to the sample to liberate conjugated tapentadol. The sample is diluted with deionized water and the analytes are separated by liquid chromatography and then quantified by mass spectrometry using multiple reaction monitoring.(Coulter C, Taruc M, Tuyay J, Moore C: Determination of tapentadol and its metabolite N-desmethyltapentadol in urine and oral fluid using liquid chromatography with tandem mass spectral detection. J Anal Toxicol 2010 Oct;34[8]:458-463)

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.

Tuesday, Thursday; 2nd Shift

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

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

4 days

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

14 days

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

New England
