At the hospital two vials of blood are drawn from the suspect. Both vials are labeled, placed in a shipping container and transferred to the toxicological lab for processing following careful chain of evidence procedures. The Scottsdale Police Department operates its own toxicological laboratory and thus does its own blood alcohol analyses using one of the vials. The suspect is informed about how to obtain the second vial if the suspect desires an independent test. Officers support the use of blood tests versus breath because they result in fewer validity arguments. Fingerprints are also taken at the hospital to insure that questions of identity of the offender may be addressed if necessary.

For a refusal, a twelve-month license suspension is served on the offender. This completes the administrative per se civil process. At that time the officer turns his or her attention to collecting BAC evidence for the criminal charge. The officer informs the suspect that a judge will be contacted and a search warrant will be requested. The subject is told: "If the judge grants the search warrant, you will no longer have the right to refuse." For daytime search warrant requests, the officer requests the search warrant in person. For nighttime search warrants, the requests are handled by a faxed telephonic search warrant request procedure. Three judges rotate turns so that one is always "on-call" and available to officers. If the suspect continues to refuse, the officer contacts the judge by telephone that then swears in the officer over the telephone. The officer faxes an affidavit and search warrant to the judge. If the judge finds probable cause the judge signs the search warrant and affidavit and faxes them back to the officer. The warrant authorizes blood to be taken from a test refuser. Reportedly, this system has worked well.

If an individual refuses to submit to a blood test and a warrant is issued, the blood sample is drawn at the police station by an on-call licensed phlebotomist. This is done because the subject can be more readily restrained in the police setting. Occasionally, for example when the officer is convinced the subject is deathly afraid of needles, a breath test is administered instead of the blood test.
