AOAC Method SMPR 2010.002 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for PCR Detection of Yersinia pestis in Aerosol Collection Filters and Liquids

AOAC SMPR 2010.002 sets the performance benchmarks for polymerase chain reaction (PCR) methods used to detect Yersinia pestis in aerosol collection filters and liquid samples. The method must achieve an acceptable minimum detection level (AMDL) of 20,000 cells per filter or 2,000 cells/genome equivalents per milliliter. Detection at these levels must meet a 5% lower confidence limit on the probability of detection (POD) of 0.95 or greater. In addition, all target strains must be detected with 100% consistency, and cross-reactivity with non-target species must not occur. These criteria are essential for reliable public health response and environmental monitoring.

The method also requires robust performance in the presence of environmental interferences such as dust, bacteria, and fungal spores. Reproducibility must be demonstrated across three independent laboratories, each producing at least ten valid data sets using standardized protocols. False positives and false negatives must remain within specified POD limits under collaborative validation. The following real-time PCR instruments are well-suited for this method when paired with validated Y. pestis assays. Each system provides the sensitivity, precision, and regulatory readiness needed for compliance with AOAC SMPR 2010.002.
