Hospital Blood

The blood alcohol level that was done at the hospital would not have been in a forensic manner since it was done for medical purposes. The significance of this is that such specimens may be contaminated with alcohol used to cleanse the skin or the port from which the blood was obtained, use of improper equipment for forensic purposes due to inadequate volume, preservative or anti-coagulant which may have been used and the blood that was analyzed would have been serum which typically yields a blood alcohol level higher than a whole blood alcohol.  A whole blood analyzed by gas chromatography mass spectroscopy (GC/MS).
