Blood Tests

Blood testing is a much more complicated process than most people think. The crime lab uses headspace gas chromotography. Basically they measure how long it takes ethanol to elute (evaporate) and reach a flame and then the intensity of that flame is measured. It is definitely not just sticking a piece of litmus paper in the blood. There are several issues that can arise during this process. Blood from other samples can get into your sample. The tube may not be able to separate ethanol from other substances. The equipment may be faulty such as the pipettes that are used to move the blood in precise quantities. They have been known to fail. The science here is intense and you need an attorney who has spent the time familiarizing himself with the procedures and deficiencies of headspace gas chromotography.
