Is this an OUI/DWI question? Usually in these circumstances police will take a blood test at the hospital. Your case sounds serious and you should retain an attorney.
This answer is offered for informational purposes only. It is not offered as, and does not constitute, legal advice. Laws vary widely from state to state. You should rely only on the advice given to you during a personal consultation by a local attorney who is thoroughly familiar with state laws and the area of practice in which your concern lies.
It sounds like you're referring to an alcohol related roadside test? If so, with the serious injuries that you had, the police would generally obtain your blood-alcohol content from the hospital. Of course, my response is limited to the information that you provided but I do suggest that you contact a Georgia attorney for help.
