What You Need to Know about Medical and Legal Blood Draws - Arizona DUI Law


If you have had blood drawn or tested as part of a DUI investigation, it’s typically for one of two reasons: 1) “Legal Blood” As requested by a law enforcement agency in regards to suspected driving under the influence; or 2) “Medical Blood” by medical personnel during injury check or treatment after an accident. It is important to know the difference between the two, as it can have a serious affect on your DUI case.

Law enforcement officials usually collect whole blood samples, which are used as forensic evidence. In this case, there are specific kits that should be used for the blood sample. State regulations and statutes outline specifications for these kits in order to ensure that every blood sample taken for forensic evidence purposes is taken and handled the same way.

Medical blood samples may only include the plasma part of the blood, which is useful for medical testing, but isn’t very reliable for alcohol testing or to be used as forensic evidence. One reason for that is that medical personnel are not required to use a standard kit or state specified method for collecting the blood. Thus, results can vary and are not sufficient to be used as forensic evidence.
