Collection of the DWI Blood Sample

The Texas Department of Public Safety has developed Instructions for the Collection and Submission of Blood Specimens For Alcohol and/or Drug Determinations. These instructions are contained on a form labeled “LAB-12b Rev.05 (xx/2014) p.1 Issued by: QAC.”

The failure to follow these instructions often results in the criminal defense attorney filing a motion to suppress or exclude the blood testing evidence from trial. For this reason, in a DWI case involving blood testing, the attorney must look carefully at the procedures used before the sample was taken, the way the sample was collected, and the procedures to submit the sample to the crime lab for analysis.

After following these instructions for the collection and submission of the blood sample, the arresting officer will submit the blood sample to the Texas Department of Public Safety Crime Laboratory using the Toxicology / Blood Alcohol Kit Laboratory Submission Form. The officer must request that the sample is analyzed to determine the presence of alcohol, drugs or both alcohol and drugs. .
