DUI Urine Test in Pinellas

If you were arrested for DUI in Pinellas County, FL, you might be asked to submit to a urine test to determine whether any controlled substances were present in your urine.

What happens if you refuse a urine test after providing a breath sample? If your breath test reading is below .08, the arresting officer might request a urine test. If you submit to a breath test but the refuses the urine test, you might still be subjected to:

  • an administrative suspension for the refusal with the Bureau of Administrative Review in Clearwater, FL; or
  • a charge for the substantive offense of a second or subsequent refusal if DAVID reveals a prior refusal on your driving record.

An experienced criminal defense attorney at Sammis Law Firm can help you fight a DUI urine test case in Sixth Judicial Circuit in Pinellas County.

DUI Urine Test – Section 316.1932(1)(a)1.b.

Florida Statute Section 316.1932(1)(a)1.b., provides:

“The urine test must be incidental to a lawful arrest and administered at a detention facility or any other facility, mobile or otherwise, which is equipped to administer such tests at the request of a law enforcement officer who has reasonable cause to believe such person was driving or was in actual physical control of a motor vehicle within this state while under the influence of chemical substances or controlled substances.

The urine test shall be administered at a detention facility or any other facility, mobile or otherwise, which is equipped to administer such test in a reasonable manner that will ensure the accuracy of the specimen and maintain the privacy of the individual involved.”

To be admissible at trial under this statutory provision, the Urine Test must be incidental to a lawful arrest. If the law enforcement officer asks for a Urine Test prior to arresting the Defendant for DUI, then the test may be held to be inadmissible at trial.

The arresting officer is trained to make sure the probable cause affidavit and narrative section of the police report clearly indicate that the arrest occurred prior to the breath request.

The officer requesting the urine sample must have reasonable cause to believe such a person was driving while under the influence of chemical substances or controlled substances. The courts in Florida have found that the term “reasonable cause” equates to “probable cause.”


How Long to Get the DUI Urine Test Results?

After the submission, the State Attorney’s Office should have the results back within two months if the sample was sent for analysis to the Pinellas County Forensic Laboratory at 10900 Ulmerton Road, Largo, FL 33778.

Pinellas County often uses its own lab instead of sending the sample to the crime lab at the Florida Department of Law Enforcement (FDLE). The lab will test the results sooner if one of the following circumstances occurred:

  1. the pending DUI is a felony charge;
  2. there was a traffic accident related to the submission; and
  3. the subject is the driver.

The request for the toxicological analysis also requires written disclosure of whether suspected controlled substances were confiscated and whether the subject admitted to using any drugs.

Where needed, either the prosecutor or a criminal defense attorney can send the specimens off to an approved external laboratory for additional analyses. Also, if the BAC level exceeds 0.100 g/dl then the drug analysis will not usually be performed.

The typical analysis performed is a basic drug screen with GC-MS Confirmation and LE3-LE Immunoassay Drug Screen for:

  • amphetamines;
  • benzadiazepines;
  • cannabinoids;
  • carisoprodol;
  • cocaine metabolites;
  • fentayl metabolites and analogs;
  • methamphetamine / MDMA;
  • methadeon metabolites; and
  • opiates.

The lab will also perform analyses for Carboxy-THC Screen and Confirmation. The most common substance found during the urine test is 11-Nor-delta-9-carboxy-THC which is the inactive metabolite found in the urine sometimes days or weeks after it is consumed.

In many of these cases, unless other arrangements are made, blood or urine specimens will be discarded after the minimum two-year retention period ends. Drug analyses and reporting are limited to identifiable controlled substances as defined by FSS 893 and 877.

Blood alcohol results for specimens collect and/or analyzed in accordance with Florida Administrative Code 11D. Blood drug quantitation will be done upon request by the State Attorney’s Office.

There is no correlation between urine and blood concentration, and therefore, no quantitations will be performed on urine specimens.

The three types of drug classes included in the respective immunoassay screens are specifically targeted in the analysis process:

  • DUI Panel – LE3 (for cases with incident dates prior to 7/1/18)
  • DUI Panel – LE5
  • Non-DUI (includes sexual assault victim’s specimens).

The statistical confidence interval for drug concentrations established by in-house analysis are as follows:

  • Ethanol ~ 99.7%
  • All other quantitations ~ 95%

DUI specimens will be tested for GHB (gamma hydroxybutyrate) upon request and only if the date/time of collection is within 12 hours of the date/time of the incident and the suspect’s behavior or performance is consistent with GHB usage. Sexual assault victim’s specimens will routinely be tested for GHB if the data/time of collection is within 12 hours of the date/time of the incident.

Other drugs may be detected and/or identified using additional analytical techniques (gas chromatography-mass spectrometry).
