What is the term for laboratory analysis to confirm the presence of biological agents?

The correct term for laboratory analysis used to confirm the presence of biological agents is diagnostic testing. This process involves specific assays and examinations that can demonstrate the presence of pathogens or their toxins in a sample. Diagnostic testing is crucial in the context of biological casualties, as it helps establish a definitive diagnosis, guiding appropriate medical management and intervention.

In contrast, treating infections refers to the therapeutic actions taken once an infection is confirmed; it does not involve the analytical process needed for identification. Preventive screening pertains to assessments aimed at detecting potential health issues before symptoms arise, rather than confirming existing biological threats. Field testing typically involves rapid, on-site assessments for pathogens, which may provide preliminary results but do not substitute for the comprehensive analysis conducted in a laboratory setting to confirm the presence of biological agents with high specificity and sensitivity.
