Average cycle threshold (Ct) score differences, standard errors, and P-values for T-tests conducted on RT-PCR results for: oral samples on FTA™ cards, kidney tissue, and oral swab (American Crows) analyses from corvid species.

Trial II, July-August 2013, California. Bolded test methods indicate the higher (therefore less viral RNA detected) scores in each pair. Ct scores were available for n = 41 of the 58 birds tested. (AMCR = American Crow; WESJ = Western Scrub-jay; YBMA = Yellow-billed Magpie).
