Drug of Abuse, Opiates Confirmation, Urine

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

Deuterated stable isotopes codeine-d6, hydrocodone-d6, hydromorphone-d3, morphine-d3, oxycodone-d3, and oxymorphone-d3 are added to patient urine as internal standards. Ammonium acetate buffer and glusulase are added to the sample and incubated at 50 degrees C to liberate conjugated drug. The sample is then diluted with deionized water and the analytes are separated by liquid chromatography and quantified by multiple reaction monitoring. A calibration curve is included with each batch of patient samples.(Unpublished Mayo method)

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 through Friday; 1st 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

5 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
