Targeted Drug Panel, Urine
Test Code: TDPU
Synonyms/Keywords
Drug screen, drug test, amines, amphetamine, methamphetamine, benzodiazepines, opiates, opioids
Test Components

Definitive/confirmatory panel to semi-quantitatively detect the use of amines/amphetamines, benzodiazepines, and opioids drug classes using Liquid Chromatography-Tandem Mass Spectrometry methodology. Quantitative results are not available, but drugs detected as “present” will be reported with a quantitative range in which it was detected.

Please see this document for a full list of drugs included in this panel, along with the detection levels of each: TDPU Test Components

NOTE: If other drug classes are also of interest (cannabinoids, cocaine, barbiturates, ethanol), it is recommended that the PCS4WO test be ordered along with this test.

Useful For
Qualitative, definitive urine drug test for the amines, benzodiazepines, and opioids drug classes.

Test Information
This test was developed and its performance characteristics determined by Marshfield Labs. This laboratory is certified under the Clinical Laboratory Improvement Amendments (CLIA) to perform high complexity testing.
  

​This assay is a semi-quantitative confirmatory test by liquid chromatography/tandem mass spectrometry (LC/MSMS). If an analyte or its corresponding metabolites are present in urine, it indicates that the patient has used the respective drugs recently. If a drug is detected, it will be reported as “present”, in three concentration ranges (low, moderate, and high) with the analyte’s specific ranges. The test includes seven amines: amphetamine, methamphetamine, MDA, MDMA, MDEA, methylphenidate, ritalinic acid; six benzodiazepines: 7-aminoclonazepam, lorazepam, oxazepam, alphahydroxyalprazolam, nordiazepam, temazepam; eighteen opiates: oxycodone, nor-oxycodone (oxycodone metabolite), oxymorphone (oxycodone metabolite), morphine, hydromorphone, 6-monoacetylmorphine (heroin metabolite), codeine, hydrocodone, gabapentin, tramadol, nor-tramadol (tramadol metabolite), fentanyl, nor-fentanyl (fentanyl metabolite), carfentanil, EDDP (methadone metabolite), and methadone. Analytes below the level of detection level will be reported as “not detected”.

This test is developed in-house with targeted analytes in consultation with pain management providers. The objective of this test is to provide useful information to help determine patient compliance or identify misuse of other drugs commonly present in our patient population.

NOTE: If other drug classes are also of interest (cannabinoids, cocaine, barbiturates, ethanol), it is recommended that the PCS4WO test be ordered along with this test.

Reference Range Information
Performing Location Reference Range
​Marshfield No reference range for drugs found in urine.  Presence of drug indicates ingestion/use only, and is not to be used for therapeutic drug monitoring.
Interpretation

Drugs are reported as “Present” or “Not Detected”. Drugs reported as “Present” are also reported as present at a “Low”, “Moderate”, or “High” level.
