AOAC Method SMPR 2015.011 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Detection of Coxiella burnetii

AOAC SMPR 2015.011 defines the minimum performance requirements for detecting Coxiella burnetii in liquid samples collected from aerosol collection devices. The method must achieve detection at or below the Acceptable Minimum Detection Level (AMDL) of 2,000 genome equivalents per mL with a probability of detection (POD) of ≥ 95% in both buffer and aerosol environmental matrices. The method must distinguish Coxiella burnetii from related and non-target organisms with false-positive and false-negative rates not exceeding 5%. It must also detect inclusivity strains at 2× AMDL and exclude non-target strains at 10× AMDL. Total time-to-result must not exceed four hours, and the system must include positive, negative, and inhibition controls.
