Lawrence Koplow has recently published an in-depth guide to blood alcohol testing in Arizona.
From the blood draw to testing in the gas chromatograph to the results printout, this guide explains in words and images, exactly how blood is tested for alcohol content after a police officer orders the test.
As Koplow points out, blood alcohol testing is a scientific process, and when any part of that process isn’t performed properly, the final results cannot be trusted. Human error along with mechanical and software problems can all prevent test results from being valid, accurate, and reliable.
