Utah DUI Urine Test
There are three potential chemical tests that can be used by Utah law enforcement agents to determine blood alcohol content (BAC) during a driving under the influence (DUI) arrest: urine, breathalyzer, and blood. While blood is the most accurate and the breathalyzer is the most commonly used for cases involving alcohol, the urine test is rarely utilized--unless the officer suspects drugs in addition to alcohol use.
DUI Urine Test Administration
If you are suspected of driving under the influence of drugs (DUI), the officer may transport you to a clinic or other medical setting for a urine test. To take the test, you may be asked to relieve your bladder and then wait 20 minutes before providing a urine sample. Your sample should then be stored in a cool location before it is transported to a lab in order to avoid an inaccurate (BAC) if alcohol use is also suspected.
Like the blood test, a urine test follows a specific chain of custody. From collecting the sample to testing the urine, every link in the chain must be accounted for in able to ensure the urine test is not contaminated in any way. If a defense attorney finds that any of the procedures were not followed correctly, your test result--and your charges--could be thrown out.
Challenging the Urine Test
The urine test is not regarded to be as reliable as the blood test; for this reason, challenging your results may be possible. If a defense attorney investigates your test and finds that your sample wasn't stored correctly or any mistakes were made, this can go a long way in benefiting your case.
Your attorney can also request your sample for independent testing. If an independent medical expert finds any inconsistencies with the results, he or she can testify on your behalf when challenging the evidence.
