Forensic Toxicology

Forensic toxicology is an important tool to a lawyer that provides an opportunity to determine the identity and/or quantity of an alleged substance, or perhaps verify that the found substance is accurate, and a true representation of their findings. 

Process of Having An Analyzed substance re-analyze

1. Court Order Issuance - A court order to issue an independent laboratory analysis of a disputed result or result verification  from the original sample must be requested by the defending attorney.  This should outline the defendants name, case number, the sample(s) with its accompanying number if available, the analyzing laboratory, etc.  Once in place, the court order document can be submitted to our laboratory through mail at Toxicology Associates, Inc., 999 Bethel Rd., Columbus, Ohio 43214, facsimile at  614-459-2409, or through email at

For Out of State Analysis

If the case is in a state other than Ohio, the sample(s) can still re-analyzed.  This is true especially if the found substance identity (i.e. Cocaine, Marijuana, etc.) needs to be verified.  Thus, a Qualitative (identification) re-analysis of a substance(s) for the most part would be helpful.  The organization/institution or perhaps the prosecuting attorney will agree to have a portion if not all of the sample evidence be submitted for re-analysis.  If it is agreed that a portion of the sample evidence can be submitted for testing, the following are specimen requirem
