Under most circumstances, for blood to be drawn legally, an arresting officer must have a search warrant. However, if an individual is being charged with felony DUI, there is a state statute permitting an officer to obtain a blood sample from them.  Currently, there is a conflict in the law on this issue in South Carolina. Officers also have the right to request a search warrant for an individual’s blood if it is suspected that the individual is under the influence of drugs rather than alcohol. The blood test must occur at a medical facility by a licensed medical professional who is responsible for properly obtaining, storing, and preserving the sample.
