ARS 28-1388 requires that a physician or another qualified person draw blood for police purposes. The person tested must also be given a chance to have someone of their choice carry out additional test(s). The law also provides that even if blood is drawn from a person for some reason other than determining alcohol or drug levels, a sample must be provided to police if requested.

A person or hospital may not be sued for collecting blood or urine in relation to a DUI arrest, unless they are seriously careless. An situation where a hospital may be sued could be where the hospital uses unclean supplies and infects a person with some disease.
