Fentanyl with Metabolite Confirmation, Urine
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Collection Container/Tube: Clean, plastic urine collection container
Submission Container/Tube: Plastic, 10-mL urine tube (Supply T068)
Specimen Volume: 3 mL
1. Collect a random urine specimen.
2. No preservative.
1. No specimen substitutions.
2. No STATS are accepted for this procedure.
3. For situations where chain of custody is required, a Chain-of-Custody Kit (T282) is available. For chain-of-custody testing, order FENTX / Fentanyl with Metabolite Confirmation, Chain of Custody, Urine.
4. If urine creatinine is required or adulteration of the sample is suspected, the following test should be requested, ADULT / Adulterants Survey, Urine. For additional information, please refer to ADULT / Adulterants Survey, Urine.
5. Submitting less than 3 mL will compromise our ability to perform all necessary testing.
Forms: Chain-of-Custody Request Form is included in the Chain-of-Custody Kit (T282). A copy of this form is also available at http://www.mayomedicallaboratories.com/it-mmfiles/chain-of-custody-request-form.pdf.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
