Urine Test

Although a breath test is more common after an OVI arrest in Dayton, OH, the arresting officer might also request a urine test. The urine test is typically requested when the officer believes that the person is under the influence of drugs but not alcohol.

Although urine tests are less accurate than a blood test, they are cheaper. Additionally, no training is required to take a urine test when compared to taking a blood sample.

If the proper procedures are not followed, a urine test can be inaccurate and completely unreliable. A false positive on a urine test is more common than for a blood test.

Procedures for Urine Testing in Dayton, Ohio

Law enforcement rarely utilizes urine tests for the purpose of determining an alleged offender’s alcohol concentration. Instead, the urine test is most frequently used when police suspect a driver has been operating under the influence of a controlled substance.

The purpose of a urine test is important because Ohio Administrative Code § 3701-53-03 clearly establishes different techniques for the specific purposes of these tests.

The only two approved techniques or methods for testing alcohol in urine are gas chromatography and enzyme assays. The approved analytical techniques or methods for controlled substances, however, are:

  • Immunoassay;
  • Thin-layer chromatography;
  • Gas chromatography;
  • Mass spectroscopy;
  • High performance liquid chromatography; or
  • Spectroscopy.

The Administrative Code states that the “analytical techniques or methods used for confirmation must have similar or improved sensitivity, specificity, accuracy, precision and linearity. The approved techniques or methods can be based on procedures which have been published in a peer reviewed or juried scientific journal or thoroughly documented by the laboratory.”

Urine tests are perhaps the most unreliable of the three types of chemical tests used in OVI arrests. Even if a person allegedly tests positive for a controlled substance, it is entirely possible that the metabolites of an illegal drug may remain in the body for several days or even months after the substance was actually used.
