Urine Testing
When an individual is suspected of driving under the influence of drugs or alcohol, they are often subjected to chemical testing to try and determine whether or not they committed a criminal offense. Breathalyzers and blood tests are the most common forms of testing for a person’s level of intoxication, but in certain situations, urine testing may be the most viable option available.
If you have been arrested for driving under the influence of drugs or alcohol, you need a strong legal defense to ensure that your rights are fully protected.

Barnett at 210-587-6464 today to discuss your case and learn more about what you can do to protect yourself from this damaging accusation.
Problems with Urine Tests
Urine testing is rare in suspected DUI cases. More commonly, it is used when a driver is suspected to be under the influence of narcotics. However, in both situations, there are serious concerns about the effectiveness of urine tests, including the following:
- Urine tests have been shown to be an unreliable indicator of blood alcohol content
- Urine tests do not demonstrate when a person ingested narcotics
- Urine tests are prone to reporting false positives for many narcotics
For these reasons, urine tests are typically considered to be suspect evidence in a DUI or DWI case.
