NCTR computer systems designed for toxicologic experimentation. IV. Experiment information system.

The Experiment Information System (EIS) is a computerized data collection, maintenance, and reporting system for specified information values collected during the lifespan of animals assigned to toxicologic investigations at NCTR. The system records and/or controls experimental variables, which might ultimately affect the results, through the operation and integration of the Diet Preparation Subsystem (DPS), the Environmental Monitoring Subsystem (EMS), the Microbiology Subsystem (MBS), and the Chemistry Data Subsystem (CDS). The fifth component of the EIS, the Experimental Data Collection Subsystem (EDCS), is responsible for handling all data generated by, or attributed to, the animals from assignment until death or removal. Through integration of these five subsystems, the history of an animal while on study is recorded and stored for later recall. In addition, "routine" and "special" reports are made available through the system software which enables stringent control of the experiment by the Principal Investigator, Animal Husbandry, and NCTR Management.
