Which of the following is not a DoD biological identification level?

• A. Initial screening
• B. Confirmatory testing
• C. Repeat testing
• D. Specimen collection

Answer: (C)

Understanding the steps used for identifying a potential biological agent in DoD operations helps explain why this option is correct. The identification process is organized into distinct stages: first, specimen collection to obtain a valid sample; second, initial screening with rapid tests to quickly flag possible positives; and third, confirmatory testing with specific, definitive methods to determine the exact identity of the agent. Repeat testing, while it may occur to verify results or resolve ambiguities, is not defined as its own standalone level in the DoD identification framework. It’s a procedural/quality control step rather than a separate stage in the identification pipeline.
