Standard Method Performance Requirements (SMPR) for Identification of Venezuelan Equine Encephalitis Virus (VEEV)

AOAC SMPR 2015.012 establishes method performance requirements for detecting Venezuelan Equine Encephalitis Virus (VEEV) in liquid samples collected from aerosol collectors. The method must detect VEEV at or below an acceptable minimum identification level (AMIL) of 5,000 genome copies/mL with a probability of identification (POI) of ≥ 95% in both sample buffer and aerosol environmental matrices. The system must achieve false-positive and false-negative rates no higher than 5%. In addition, the method must distinguish VEEV from closely related viruses such as EEEV, WEEV, Mucambo, and Tonate, each tested at 10× AMIL to confirm selectivity. The total time from sample recovery to assay result must not exceed four hours.
