Drug Abuse Survey with Confirmation, Urine
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Testing begins with screening assays. If alcohol (ethanol) screen is positive, then the gas chromatography-flame ionization detector confirmation with quantification will be performed at an additional charge. If barbiturates, benzodiazepines, cocaine and metabolites, phencyclidine, or tetrahydrocannabinol metabolite screen is positive, then the gas chromatography-mass spectrometry (GC-MS) confirmation with quantification will be performed at an additional charge. Amphetamines and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry (LC-MS/MS) at an additional charge.
Specimen Type Describes the specimen type needed for testing
For situations where chain of custody is required, a Chain of Custody Kit (T282) is available. For chain-of-custody information, see CDAUX / Drug Abuse Panel with Confirmation, Chain of Custody, Urine.
Some drug treatment programs do not require confirmatory testing of screen-positive specimens. In those settings, UDOA / Drug Abuse Survey, Urine is a less costly option.
Additional Testing Requirements
If urine creatinine is required or adulteration of the sample is suspected, the following test should be requested, ADULT / Adulterants Survey, Urine.
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.
Supplies: Urine Container, 60 mL (T313)
Collection Container/Tube: Plastic urine container
Submission Container/Tube: Plastic, 60-mL urine container (T313)
Specimen Volume: 30 mL
1. Collect a random urine specimen.
2. Submit 30 mL in 1 plastic container.
3. No preservative.
1. No specimen substitutions.
2. No STATS are accepted for this procedure.
3. Additional drug panels and specific requests are available. Call Mayo Medical Laboratories at 800-533-1710 or 507-266-5700.
4. Submitting less than 30 mL will compromise our ability to perform all necessary testing.
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.
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
