Our firm owns both models of the Intoxilyzer 5000, the machine used in Texas to test someone suspected of drunk driving. We know how they work and we know how easy it is to get false results. In some cases, we can attack a high BAC reading through challenging the experience or credentials of the machine operator, in others we can challenge the maintenance and condition of the machine itself. A reliable gas chromatograph costs, used for blood testing, about $100,000, but some law enforcement officials use an $8,500 Breathalyzer. You get what you pay for.

Fighting toxicology reports is a highly effective strategy for DWI defense and felony DWI charges. We have won DWI cases involving BAC as high as .27 by challenging toxicology reports. Having taught CLE courses on winning strategies in DWI defense for years, attorney Isenberg understands the details of these tests, such as false positives for toluene and alkaloids generated by special diets and medication.

Texas DWI Blood Tests

We can use similar methods to build a defense for cases involving blood samples. Working with forensic experts, we will compare the conduct, analysis, and storage of blood samples in your situation to the practices necessary for safe and reliable results.
Paying close attention to blood and breath tests even comes in handy when evidence of guilt in a DWI is beyond question. Cases involving a BAC over .15 normally result in a mandatory ignition interlock installed at the defendant’s expense. Even shaving a few points off the initial BAC reading can make a significant difference in the consequences of a DWI conviction.
