661—150.2 (691) Purpose and scope of work. The laboratory provides forensic science services to law enforcement agencies within the state of Iowa. The laboratory shall, within its capabilities, conduct analyses and comparative studies on physical evidence to aid in any criminal investigation, when requested by a prosecuting attorney, a medical examiner, or a law enforcement agency.
	 150.2(1) Resource or capability limitations.
	  a.   	 The laboratory administrator may refuse any request to conduct an analysis when, in the judgment of the administrator, the laboratory is unable to adequately conduct the requested analysis, either because of resource limitations or because the analysis is not within the professional capabilities of laboratory personnel.
	  b.   	 The laboratory administrator may establish a policy excluding evidence of specific types or evidence arising from certain types of cases from being accepted by the laboratory, if the administrator finds that such a policy is necessary either due to resource constraints, safety concerns, or the professional capabilities of laboratory personnel. Any policy adopted pursuant to this paragraph shall be provided to all county attorneys, medical examiners, and law enforcement agencies within Iowa.
	  c.   	 If analysis by the laboratory of specific evidence arising from a criminal investigation in Iowa has been excluded pursuant to either paragraph “a” or “b,” the administrator may, at the administrator’s discretion, assist the agency requesting the analysis in locating the services of another laboratory able to perform the requested analysis.
	 150.2(2) Exclusion by law. The laboratory shall only perform analyses which have arisen from, or will aid in, criminal investigations or which are otherwise provided for by law.
