Toxicology Exams
Tox Cases
DUID Cases
How does the OCCL process a DUID case?
• All blood cases with driving violations are tested for ethanol and other volatiles.
• All blood cases are screened for 300+ drugs.
• All positive screens are confirmed automatically.
• All drug requests are conducted if reasonable and sufficient sample volume is provided; not already included in screen.
• All DRE samples are comprehensively tested including all requests regardless of charge.

Policies For Alcohol and Drug Testing
• Limit testing based on BAC
– Common amongst other forensic laboratories doing DUID casework
• Limit testing based on Scheduled drugs
– Each state is different, if policy exists, based on statute
• Resource coupled with technology limitations may drive testing decisions.
