Standard Method Performance Requirements (SMPR) for DNA-Based Methods of Detecting Bacillus anthracis in Field-Deployable and Department of Defense Aerosol Collection Devices

AOAC SMPR 2016.006 defines the minimum performance criteria for DNA-based methods used to detect Bacillus anthracis in aerosol collection devices, particularly for Department of Defense field applications. The method must detect the Ames strain of Bacillus anthracis at an Acceptable Minimum Detection Level (AMDL) of 2,000 spores per milliliter in collection buffer. A Probability of Detection (POD) of at least 95 percent is required at this level in both collection buffer and environmental matrix materials. False-negative and false-positive rates must not exceed 5 percent, and total time-to-result must not exceed four hours. Methods must also include internal controls such as positive, negative, and inhibition checks to ensure result reliability.

To meet inclusivity requirements, all inclusivity strains of Bacillus anthracis must yield positive results when tested at two times the AMDL (4,000 spores/mL). For exclusivity, the method must yield negative results for all listed exclusivity organisms when challenged at ten times the AMDL (20,000 spores/mL). These standards help ensure high specificity in environments where cross-reactivity and false positives can compromise mission-critical operations. Instruments capable of supporting such rigorous validation criteria include the QuantStudio 12k Flex with AccuFill, BioFire FilmArray Torch, ABI 7500 Fast DX, ABI ViiA 7, Cepheid GeneXpert, and Bio-Rad CFX96 Touch systems.
