Blood Test

Blood tests are considered to be simultaneously the most accurate method of testing for an alleged offender’s drug or alcohol content and the most invasive method of testing.

Breath testing is usually the preferred method for police officers because the associated requirements are far less rigorous. Breath testing is cheaper because no scientific training is required to administer the test. Prosecutors also like breath testing because it is often easier to get the breath test results admitted into evidence.

Although blood testing is more expensive and time consuming, it becomes necessary in cases involving a refusal to submit to breath testing or when the suspect is receiving medical treatment and a breath test is not practical.

Blood tests are especially common following accidents when alleged offenders suspected of driving under the influence (DUI) may be unable to provide other types of samples. It is important to understand when and why state law in Ohio grants police officers tremendous latitude in obtaining blood samples.

When Blood Tests Are Used in Ohio DUI Cases

In order for a blood specimen to be considered valid, Ohio Revised Code § 4511.19(D)(b) states that the sample must be collected within three hours of the alleged offense. Ohio Administrative Code § 3701-53 establishes several protocols for blood tests that must be followed in regards to how the samples are collected, the qualifications of the people performing the blood draws, and the instruments used in collecting the samples.

Ohio Revised Code § 4511.191(A)(5)(b) establishes that law enforcement officers can “employ whatever reasonable means are necessary to ensure” that alleged offenders submit to a chemical test of their whole blood or blood serum or plasma if they refused to submit to a chemical test.

This means that police may be able to legally pin a person down and draw their blood while being immune from criminal and/or civil liability for any claims of assault.

Many law enforcement agencies around Ohio often have local judges on call 24 hours a day, seven days a week to issue warrants specifically for the purpose of authorizing blood tests. Police are often quick to make these phone calls for suspected drunk driving cases during sobriety checkpoints, holiday weekends, or when alleged offenders have been previously convicted of multiple OVI offenses.

Warrantless, non-consensual blood draws may be admissible in certain limited cases with exigent circumstances.

Blood Test Problems in Cincinnati OVI Cases

The taking, storing, and testing of blood specimens are all extremely complex procedures that must adhere to very strict requirements under state law. Any deviation from the standards established under Ohio law can result in a blood specimen possibly producing a false positive and thus becoming inadmissible in court.

Even if a blood test allegedly showed you were under the influence of alcohol or a controlled substance, some of the reasons a test may be thrown out include, but are not limited to:

  • Analyst lacked proper permit;
  • Failure to meet laboratory requirements;
  • Sample was contaminated;
  • Sample was illegally obtained;
  • Sample was improperly stored;
  • Test performed by individual who did not meet state standards;
  • Test was not performed within three hours of the alleged violation; or
  • Whole blood value was actually plasma or serum.

Resources for DUI Blood Tests in Ohio

Missouri v McNeely — In 2013, the United States Supreme Court heard and decided this case of a man who was stopped for allegedly speeding and crossing the centerline. The police officer noticed signs of intoxication and the man failed field sobriety tests but refused to submit to a portable breath test, a breath test at the police station, and a blood test at a nearby hospital. The officer ordered a blood draw without the man’s consent and arrested him for drunk driving after the results of the blood test showed a blood alcohol concentration (BAC) of 0.154 percent. While the police argued that any delay in obtaining a warrant would lead to a destruction of the evidence, the trial court, the Missouri Supreme Court, and the United States Supreme Court all agreed that the forced blood draw was a violation of the man’s Fourth Amendment rights prohibiting unreasonable searches and seizures. The case put important limits on the ability of a law enforcement officer to obtain a warrantless and forced blood draws using the exigent circumstances exception to the Fourth Amendment.
