Forensic Toxicology

ChemaTox Laboratory has been providing forensic toxicology services to the law enforcement, coroner, criminal defense, and civil litigation communities since 1977.

Forensic toxicology provides specialized, comprehensive toxicology services to the legal community. Forensic toxicology demands extremely high-quality testing, meticulous documentation, and analysts both skilled in the laboratory and consultation.

ChemaTox’s forensic testing procedures satisfy the most rigorous requirements of forensic laboratory analysis and qualify as evidence in courts of law. In addition, ChemaTox provides services in expert testimony, consultation, documentation, and case review.
