Urine Drug Testing

Urine provides the middle ground in drug testing, showing a history of drug exposure shorter than hair, but longer than oral fluid. A sample of 10 ml provides information on the last 2-3 days of drug history for most drugs. We confirm all presumptive positive results by LC-MS/MS or GC-MS, and offer customized urine testing panels with over 50 drug and alcohol biomarkers, including propofol glucuronide (e.g. Diprivan®).

*Ethanol is automatically tested in urine panels 10 and above.

Testing Details

Panel Name: Urine Testing

Panel Description: Urine Testing Drug Panel

Type: Profile

Matrix: Urine

Collection Container: Leakproof Polypropylene

Sample Amount: 10 ml

Storage Conditions: Refrigerated

Transport Conditions: Ambient

Method: Initial screen and confirmation

Turnaround Time: Generally, the standard turnaround time for reporting negative screening test results is the next business day, with an additional 1-2 business days for specimens that require confirmatory testing. Turnaround time begins from receipt of the valid specimen –accompanied by a properly documented valid order– into the laboratory. Some tests require additional time to process and will fall outside the standard turnaround time window.

Can a hair test be manipulated by the donor?

Yes. Bleaching, perming, dyeing and straightening can affect the outcome of a hair test. Cosmetically treated hair should not be collected.

How do PEth results differ from Urine EtG/EtS results?

Recent studies have indicated that low-level positive EtG results can be produced by certain agents like hand sanitizers and mouth wash (incidental exposure). Research indicates that the volume of alcohol required to trigger a positive PEth result is far above the level available from incidental exposure.

How much is needed for an adequate urine sample?

Requested sample volume is 10 milliliters.

Q: Why are both ethyl sulfate (EtS) and ethyl glucuronide (EtG) included in urine testing for alcohol use, but only EtG in fingernail or hair testing?

A: For urine testing, it is standard practice in the field of toxicology to include both EtS and EtG, because EtG is subject to bacterial production and degradation if a urine sample is contaminated (e.g. when the donor has a urinary tract infection). EtS is not subject to bacterial production or degradation, and provides a second, more reliable alcohol biomarker in these urine contamination scenarios. Other specimens types, such as fingernails and hair, do not have this issue, so only EtG is measured in those sample types.

What is the detection window for urine?

A sample of urine provides a drug history from the last two to three days for most drugs, and an even longer period for marijuana.

Will a UTI affect the result of drug and/or alcohol testing?

Certain bacteria may interfere with drug detection but will not generate a false positive. Fermenting bacteria in the presence of excess glucose may produce ethanol in the bladder and in the specimen cup.
