What is Retrograde Extrapolation?

Retrograde extrapolation is a mathematical process, based on sound scientific principles, that is used routinely in pharmacology, toxicology, and clinical medicine. This process may be applied to the situation of ethyl alcohol consumption with reliability when reasonable assumptions are made concerning absorption rates, elimination rates, and patterns of alcohol consumption, including drinking duration and volume consumed.

In layman ‘s terms, it is the process used by the State to determine what your alcohol concentration was at the time of driving based on the specific facts obtained during the DWI investigation.
