Maryland DUI Blood Test

Every year, thousands of Maryland drivers are arrested for driving under the influence (DUI) due to their unsuccessful chemical test results. Although breathalyzers are the most common form of these tests, a Maryland DUI blood test may be used in certain situations.

Whether you are given a breathalyzer or a blood test, a chemical test measures the amount of alcohol in your bloodstream—a percentage referred to as blood alcohol content, or BAC. Under federal law, a person’s ability to drive becomes impaired once his or her BAC reaches 0.08% or higher. As a result, if a breathalyzer or blood test indicates you have a BAC above this limit, you can expect to be arrested and charged with DUI.

In general, blood tests are only administered if a suspected DUI offender is involved in a serious auto accident and is either injured or unconscious. Unlike a breathalyzer, the law does not require you to consent to a blood test.

All blood tests must be performed at a hospital and analyzed by a state laboratory in order for their results to be used as evidence against you. In addition, the test must be administered within two hours of your arrest and performed by a professional while using the appropriate equipment. Failure to comply with these requirements could lead to inaccurate test results—which means they may be deemed inadmissible in court.

Despite being more reliable than other chemical testing methods, blood tests are prone to human error—in fact, research suggests the results can vary by as much as 25%. In light of this fact, it’s easy to see why so many drivers decide to obtain legal representation for their DUI case.

Of course, challenging your blood test will not be easy. Most drivers must have professional help to avoid a drunk driving conviction.
