Sensitivity analysis : • AMDL = 50,000 copies/mL target region of Variola virus • ≥ 500 bp must receive permission from WHO i ti i t th O th i i hibit d • nser on n o ano er r opoxv rus s pro e Establish Probability of Detection at AMDL w/in collection buffer (≥ 95%) Establish Probability of Detection at AMDL w/in aerosol environmental matrix (≥ 95%) • Inclusivity panel – Variola virus : ≥ 2 strain target regions • at least one from each primary clade ( Li, et. al. PNAS (2007) Oct. 2;104(40):15787-15792.) • encompass differences in target region • Based on bioinformatic analysis Ensure all inclusivity strains are detected at 2X AMDL in collection buffer Ensure all inclusivity strains are detected at 2X AMDL in environmental matrix Ensure target is detected at 2X AMDL w/in pool of environmental panel organisms (pools of up to 10 organisms at 10X AMDL for each) Variola Working Group SMPR: Tailor Panel to Assay Based on Bioinformatics
Specificity analysis: • Exclusivity panel – near neighbor ( Orthopoxvirus ): • All poxvirus strains listed in the table (one from each major clade) • See AOAC Website for the most updated list Variola Working Group SMPR: Tailor Panel to Assay Based on Bioinformatics
