Concerning toxicology testing by certified or accredited laboratories.

HB 1228 establishes standards for toxicology testing in Washington State DUI cases. It requires that blood and breath tests used to determine alcohol or drug impairment must be conducted by either a laboratory certified under the ISO/IEC 17025 standard for forensic toxicology or by an individual holding a permit from the state toxicologist. The bill specifies detailed procedures for breath testing, including a 15-minute observation period without eating, drinking, or smoking, and precise calibration requirements, while also mandating that blood draws be performed by specific licensed healthcare professionals under defined conditions. This law directly affects law enforcement, testing laboratories, and individuals charged with driving under the influence by setting clear criteria for test admissibility in court.
