Why DWI Blood Tests Aren't Always Right
Here's the thing nobody tells you: blood test results in DWI cases can be riddled with errors. We tend to trust lab results because they sound scientific and official. But science, as it turns out, is only as good as the people running it.
Lab technicians handle thousands of samples every single month. One spilled tube, one mislabeled vial, one sloppy chain-of-custody form — boom, your life gets wrecked over a mistake.
And yes, we're talking real errors, not hypothetical ones. Contaminated samples, improper storage temperatures, and even expired testing equipment show up more often than you'd be comfortable knowing. The scary part? Most people never question them because the results look so official.
Contamination: The Silent Culprit
You wouldn't believe how easily a blood sample can get contaminated in a lab. Bacterial fermentation, for instance, can actually increase the alcohol concentration in a stored blood vial. That means your blood could test higher than it really was — sitting on a shelf, somehow growing stronger.

Storage conditions also matter more than most people realize. If a sample sits in the wrong temperature for even a few hours, the results can drift. And when the stakes are a criminal charge? A few points of drift can change everything.
Chain of Custody: Where Things Fall Apart
Think of chain of custody like a phone number you used in middle school. It's supposed to get passed smoothly from person to person. But what happens when someone drops it along the way?
Missing signatures, broken seals, and undocumented sample transfers are alarmingly common in DWI cases across Dallas County. Every gap in that chain creates a reason to challenge the test result. And experienced attorneys know exactly where the cracks tend to form.
Heads up: this isn't your fault. You didn't do anything wrong — you just got caught in a system that's way more flawed than most people assume.
