In addition to laboratory analyses, it may also be useful to identify institutions where the same threat agent has been produced by the same (or a similar) process, since the producer of the agent may have learned methods at a university or similar institution.

We present a mathematical framework for assessing the quality of signature systems in terms of fidelity, risk, cost, other attributes, and utility—a method we call Signature Quality Metrics (SQM). We demonstrate the SQM approach by assessing the quality of a signature system designed to predict the culture medium used to grow a microorganism. The system consists of four chemical assays and a Bayesian...
