Upon the trial of a civil or criminal action or proceeding arising out of acts alleged to have been committed by a person while operating a motor vehicle in violation of section 321J.2 or 321J.2A, evidence of the alcohol concentration or the presence of drugs in the person's body substances at the time of the act alleged as shown by a chemical analysis of the person's blood, breath, or urine is admissible. If it is established at trial that an analysis of a breath specimen was performed by a certified operator using a device and methods approved by the commissioner of public safety, no further foundation is necessary for introduction of the evidence.
