Dr. Brautbar: Forensic Toxicology Expert

Dr. Nachman Brautbar specializes in forensic toxicology and internal medicine aspects of injury in the workplace, product liability, and standard of care. Forensic toxicology is essentially the analysis of drugs, alcohol and poisons in the body fluids and the interpretation of those results which are typically used in a court of law. In general, forensic toxicology is a specialty area of chemical, physiological and analytical data. The use of forensic toxicology is paramount to the outcome of a legal case as it uses the science of "toxicology" to present hard evidence to the court system. "Toxicology" is defined as the science of unfavorable effects on living organisms.

Dr. Brautbar has consulted on a number of cases involving patient litigation, drug interactions, adverse reactions, overdose, toxic exposure and other common toxicology matters. His area of expertise includes forensic toxicology, medical toxicology, environmental toxicology, DUI, internal medicine, clinical pharmacology, nephrology, and alcohol abuse. As an expert in toxicology, he has been consulting for over two decades working closing with legal and law enforcement professionals in the city of Los Angeles, CA and other areas in the state.

Over the years, Dr. Brautbar has worked closely with municipalities, insurance companies and attorneys consulting on many drug-related cases. He has consulted on cases involved illegal and prescription drugs, poison, alcohol and other chemicals. When working with an investigative team, he helps team assess the drug-related elements affecting a case.

The primary function of a toxicology expert witness is to support or refute any evidence presented in a case. On matters as common as a DUI, a toxicology expert witness may be selected to serve as a consultant on the results of the samples. Other cases may require an expert witness in forensic toxicology with a strong background in medical toxicology to consult on the concentrations and specific combinations of drug, alcohol and other toxins such as Arsenic, found in a person’s system.

Dr. Brautbar has worked in a number of United States civil and criminal cases ranging from negligence to malpractice. His expertise and track record has made him a leading, reliable source on toxicology in the Los Angeles area and across the United States. This skill set continues to be an extremely important part of the ever growing Judicial System. Dr. Brautbar has assisted in many cases in which his work has led to many successful outcomes, making his mastery an invaluable asset to forensic based cases.
