AOAC Method SMPR 2016.010 Instrumentation Guide
Standard Method Performance Requirements (SMPRs) for DNA-Based Methods of Detecting Burkholderia pseudomallei in Field-Deployable, Department of Defense Aerosol Collection Devices
AOAC SMPR 2016.010 establishes critical performance requirements for the DNA-based detection of Burkholderia pseudomallei in Department of Defense (DoD) aerosol collection devices. This method mandates an acceptable minimum detection level of 2,000 cells/mL with a required probability of detection (POD) of 0.95 or higher. It also enforces a maximum false-positive and false-negative rate of 5%, ensuring high confidence in operational settings. Inclusivity studies must confirm detection of all variant strains at 2× AMDL, while exclusivity must be verified at 10× AMDL. Results must be generated within a maximum of four hours to be applicable for rapid response scenarios. Instruments alone do not ensure compliance—each system must be paired with a validated assay capable of meeting all SMPR benchmarks, including AMDL, POD, and specificity.
The instruments listed below are capable of supporting the method requirements outlined in SMPR 2016.010 when properly validated. These platforms span real-time PCR, digital PCR, isothermal amplification, and sequencing technologies, providing laboratories and field teams with flexible implementation options. Their performance characteristics support both rapid field screening and high-throughput laboratory confirmation.
