Blood and Urine Test

Blood Test

Blood tests are generally the most reliable test to determine if a person has committed an OVI (R.C. 4511.19). However, there are many ways to challenge the blood test result including, but not limited to:

  • Is the lab that tested the blood properly accredited at the time of testing?
  • What is the lab's testing and calibration procedures?
  • What was the identification and source of all internal standards, verifiers, blanks, and controls that were run within the batch in for the sample in this case?
  • Was the blood sample collected, stored, and tested in the proper manner?
  • Was a gas or liquid chromatograph used?
  • Was a mass spectrometer used?

Also, it is important to know when the accident occurred and when the blood draw took place. The blood draw must take place within three-hours as required by R.C. 4511.19(D)(1)(b). There are other requirements per O.A.C. 3701-53-05 that must be met for the collection and handling of blood and urine samples.

Blood Re-Testing

You can also have your blood sample retested by an independent lab of your choosing. The original testing lab may have made an error. Attorney Christopher Fogt may ask the Court to allow for your blood to be re-tested.

Urine Test

The collection of urine must also meet the requirements per O.A.C. 3701-53-05. Urine tests are not as common as blood tests, and especially not as common as breath tests.
