Articles Tagged with DWI Blood Tests

While breath testing is often the go-to method for measuring a driver’s blood alcohol concentration (BAC), certain situations call for blood testing in a DWI case. Law enforcement may suspect drug involvement, or the driver may be unable (or unwilling) to provide a valid breath sample on an approved device. DUI fatalities tend to involve blood testing, as it the more accurate method to confirm the different possible sources of impairment and the respective concentrations of each.

Understanding when officers rely on blood draws in North Carolina—and how they handle chain-of-custody requirements—can help clarify whether the reported results are reliable or open to challenge.

This article explains common scenarios leading to blood tests, the difference between hospital versus EMT blood draws, how labs analyze samples using Gas Chromatography–Mass Spectrometry (GC-MS), and what legal issues can arise involving consent, patient privacy, and chain of custody.
