OVI Blood Test

Although the breath test is the most common type of chemical test requested after an OVI arrest in Dayton, OH, the arresting officer might request a blood test or a urine test. The blood test is particularly common when OVI suspect is taken to the hospital because of a medical emergency or injuries from a crash. In those cases, the breath test or urine test might be impractical.

Blood testing also occurs when a suspect requests an independent blood test after submitting to a breath or urine test. The right to an independent chemical test (at the person’s own expense) is guaranteed under Ohio Revised Code § 4511.192(B).

Many consider the blood test to be the “gold standard” for determining the suspect’s blood alcohol content or the presence of a controlled substance. Nevertheless, breath testing can be inaccurate or unreliable for a variety of reasons.

In these cases, criminal defense attorneys in Ohio will often file and litigate motions to suppress or exclude the breath test results. Those motions often involve violations of statutory rules or administrative regulations in the collection or testing of the sample. Other motions can involve an illegal search and seizure of the blood under the Fourth Amendment of the U.S. Constitution.

Blood Tests in Ohio DUI Cases

Ohio Revised Code § 4511.191(A)(5) provides law enforcement with extraordinary power to “employ whatever reasonable means are necessary to ensure” that alleged offenders submit to chemical tests of their whole blood, blood serum, or plasma.

Police may be able to actually pin down alleged offenders for blood draws, and still be immune from criminal and civil liability based upon a claim for assault, battery or other types of claims unless the officer acted with “malicious purpose, in bad faith, or in a wanton or reckless manner.”

In many cases, law enforcement agencies have local judges on call 24 hours a day, seven days a week to issue warrants specifically authorizing blood tests in alleged OVI cases. Much like breath testing procedures, blood tests need to satisfy a plethora of strict standards in how they are conducted.

Police may seek these warrants during holiday weekends or in cases involving alleged repeat DUI offenders.

Even when a warrant is not obtain for the blood draw, the officer might allege that the subject agreed or consented to the blood test. Exigent circumstances might also permit a warrantless and non-consensual blood draw under limited circumstances.
