AOAC Method SMPR 2010.001 Instrumentation Guide

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

AOAC SMPR 2010.001 outlines the method performance requirements for PCR-based detection of Francisella tularensis in aerosol filters and liquid samples. The method mandates detection of the organism at an Acceptable Minimum Detection Level (AMDL) of 20,000 cells per filter or 2,000 genome equivalents per milliliter. Probability of detection (POD) must meet a 5% lower confidence limit of 0.95 or higher. Methods must also demonstrate 100% inclusivity for target strains and 100% exclusivity against near-neighbor organisms. Environmental interferences from dust, bacteria, and other contaminants must not affect results.

To meet these criteria, instruments must deliver highly sensitive detection, excellent thermal uniformity, and strong reproducibility across collaborative validation studies. Systems should accommodate a wide range of PCR chemistries and offer traceability features suited for regulated environments. The following real-time PCR instruments meet these specifications when paired with validated assays. Each platform offers robust performance for laboratories monitoring biological threats or conducting environmental surveillance. These systems ensure compliance with AOAC SMPR 2010.001 in both routine and high-consequence testing scenarios.
