Tibial Nail Removal in Younger and Active Patients with Discomfort: A Cohort Study of 40 Patients

An essential part of any sampling or analytical process is ensuring the integrity of the sample from collection through data reporting. A Chain-of-Custody is necessary if there is any possibility that litigants will use analytical data or conclusions based upon that data in litigation. This chapter describes the components of a Chain-of-Custody and the procedures for the use. "Chain-of-Custody" is defined as the documentation of the history of samples through all possession and handling from the time of collection through analysis and final disposition. Consider all ambient sampling data collected in the State of Indiana as having potential use in court; therefore, all sampling data must follow a Chain-of-Custody procedure. In cases involving no litigation, many Chain-of-Custody procedures are still useful for routine control of validity of sample data. 2.0
