AOAC Method SMPR 2016.007 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Detection of Francisella tularensis in Aerosol Collection Devices

AOAC SMPR 2016.007 establishes method performance requirements for nucleic acid-based detection of Francisella tularensis using aerosol collection devices. The method must achieve an Acceptable Minimum Detection Level (AMDL) of 2,000 genomic equivalents per milliliter in sample collection buffer. At this concentration, the system must demonstrate a Probability of Detection (POD) of at least 95 percent. The system false-negative rate must be no greater than 5 percent, and the false-positive rate must also not exceed 5 percent when tested using environmental matrix materials. The maximum allowable time-to-result is four hours from sample collection to final result.

To meet inclusivity requirements, the method must detect all 15 designated inclusivity strains of Francisella tularensis at two times the AMDL, or 4,000 genomic equivalents per milliliter. For exclusivity, the method must not produce positive results for any of the 29 exclusivity organisms when tested at ten times the AMDL, or 20,000 genomic equivalents per milliliter. Instruments must also demonstrate stable performance across aerosol matrices and varying environmental conditions. Reliable amplification, assay reproducibility, and strong discrimination between true positives and false positives are critical. The platforms listed below support these requirements when configured with validated workflows and appropriate quality control procedures.
