Florida DUI Urine Test Lawyer Defending Your Rights Against Unreliable Tests

In Florida DUI cases, urine tests are used when blood and breath alcohol tests are inconclusive or when drugs are involved. Although prosecutors rely on urine test results to build their cases, urine tests are among the least reliable methods for determining actual impairment.

The Kessler Law Firm has over four decades of DUI defense experience with a deep knowledge of DUI science. Florida DUI urine test lawyer Michael Kessler aggressively advocates for his clients facing DUI charges by exposing the scientific flaws in urine test accuracy.

Why Are DUI Urine Tests Unreliable?

Detection vs. Impairment

When urine tests are used to detect alcohol, alcohol doesn’t show up in urine until it is metabolized in the body. Urine composition changes between the time you were pulled over and when the urine sample is collected, likely because you ate, drank, and used the bathroom since. Traces of alcohol or drugs can appear in urine tests long after the effects wear off, making them an unreliable indicator of impairment when you were driving.

Improper Sample Collection

Urine tests can be easily contaminated. It can also be incredibly difficult for some people to provide a sufficiently sized urine sample, which affects the ability to test it and get accurate results. Missteps in collection procedures can invalidate urine test results.

Chain of Custody Errors

Urine samples need to be taken to a lab for analysis. Not knowing who has custody of the sample and when creates an opportunity for it to be lost, mishandled, or improperly stored, affecting the accuracy of test results.

Inaccurate Lab Tests

Lab technicians can make mistakes when reviewing urine test results. Hormonal balance, diet, and medications can create false positives and misrepresentations of the results. This makes urine tests an unreliable way to gauge impairment.

Defense Strategies for Urine Test Cases

The Kessler Law Firm will fight to suppress unreliable evidence before your trial, and deploy these defense strategies:

Test Results vs. Impairment

Since there is such a wide gap between the time that you were driving and when you submit the urine sample, urine tests often do not provide an accurate measure of actual impairment. It is frequently argued that urine test results are too unreliable to be used as evidence.

Review Lab Practices

Everything from how urine is collected to who controls the sample and how it is stored will affect the test results. Demanding chain-of-custody records can help prove that too much time passed between the urine sample collection and testing, or that there was potential for mishandling or improper storage.

Challenge Test Results

The Kessler Law Firm works with expert witnesses who can challenge the results of lab tests. Urine test accuracy can be questioned based on the frequency of false positives, your physiology, and other factors that make urine tests unreliable.
