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®) and designer stimulants (i.e. Bath Salts).

Collection

Collection Instructions
Collection Steps
Secure collection area
Assure that the collection area is secure, the sink water is off and the toilet water is blue.
Escort the donor to the collection area
Escort the donor to the collection area.
Examine the photo identification
Examine the photo identification (e.g. driver’s license, state identification card, passport) provided by the donor. Verify both the picture and the signature of the donor.
Allow the donor to collect the specimen
Give the donor the new, unused urine collection cup and allow the donor to void in the restroom. Do not allow the donor to take anything into the restroom (e.g. purse, jacket etc.)
Ready specimen for transport to lab
Upon receipt of the urine cup with a minimum of 10 millileters of specimen, check the temperature strip and, if acceptable (between 90o F and 100o F), cap the collection/transport cup and annotate the temperature on the Custody and Control Form. The donor must witness this closing of the
collection/transport cup. Seal the collection/transport cup with the security seal and allow the donor to initial the seal.
Label the urine container
Label the urine container with the donor’s name, date and I.D. number.
Initial the security seal and the urine container
Initial the security seal and the urine container, and place a barcode sticker from the Custody and Control Form onto the specimen container.
Have the donor sign and date the form
Have the donor sign and date the Custody and Control Form in the appropriate places (optional). Select the required panels to be tested.
Collector must sign and date the form
The collector must sign and date the Custody and Control Form at the appropriate places.
Package the specimen for transport
Place the urine container in the small pouch and the Custody and Control Form in the large pouch of the watertight specimen bag.
Place the bagged specimen(s) in an IATA compliant box
Place the bagged specimen(s) in an IATA compliant box.
Place the box in the courier’s transport clinical over-wrap
Place the box in the courier’s transport clinical over-wrap.

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. The PEth blood assay is an ideal tool to define low-level positive EtG results. 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.

Why was one matrix positive and another negative on the same donor?

There are several explanations for this. 

  1. Different sample matrices have different detection time frames. The result of any second collected specimen has no bearing on the validity of a first collected specimen. For example, a hair sample with a three month window of detection might test positive for a particular substance, while a urine sample from the same donor, with a 2-3 day window of detection, might test negative. In this case, the donor has used that substance within the past three months, but may not have used it within the most recent three days.
  2. The result of any second collected specimen has no bearing on the validity of a first collected specimen. Therefore, a negative result observed for the umbilical cord does not refute a positive result observed on the maternal urine specimen and the reverse is true as well. There are many legitimate reasons for discrepant urine and umbilical cord results. 
  3. The urine specimen was a screen only result and was not confirmed using an appropriate mass spectrometric method. The screen only urine result is a clinically valid result, however, without an appropriate mass spectrometric confirmation, the urine result has no value in a forensic proceeding. 
  4. Lastly, some placentas can prevent some compounds from reaching the fetus. There are documented cases of maternal ingestion without in utero exposure.

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.
