What is the primary use of antigen antibody immunoassays in CBRN assessment?

• A. Provide definitive identification
• B. Detect chemical hazards
• C. Determine radiation exposure
• D. Presumptively Identify Biological agents

Answer: (D)

Antigen-antibody immunoassays are used to rapidly detect a specific biological agent by binding its antigens with antibodies. This yields a presumptive identification, allowing quick determination that the agent is likely present and enabling immediate response actions. They’re designed for speed and field use, but their results aren’t definitive—confirmatory testing in a lab is needed for absolute identification. These assays are not used to detect chemical hazards or to determine radiation exposure.
