Requests to expedite testing for samples submitted to the Toxicology section are handled on a case by case basis depending on circumstance and available resources. Every effort will be made to complete drug screening and alcohol analysis by the requested date, however, please understand that completion of further drug confirmation testing may not be possible on shorter notice. To request a rush status for a toxicology submission, it is highly recommended that a letter signed by the prosecuting attorney listing the trial date is provided to the laboratory and either accompanies the sample(s) or is submitted via fax to the laboratory’s Evidence Room at 515-725-1523. It is ideal to receive this letter a minimum of 14 days prior to the anticipated trial date.
