The rate of agreement between the Imager-assisted review result and the manual review result from
the previous table is presented below. PPA is the positive percent agreement, percent of specimens
of ASC-H+ diagnosis with Imager-assisted review by a majority of laboratory CT/Pathologists
among all specimens of ASC-H+ diagnosis with manual review by a majority of laboratory
CT/Pathologists. NPA is the negative percent agreement, percent of specimens of
<ASC-H diagnosis with Imager-assisted review by a majority of laboratory CT/Pathologists among
all specimens of <ASC-H diagnosis with manual review by a majority of laboratory
CT/Pathologists.

In Table 23 for ASCUS+, the number of specimens is shown for which various levels of agreement
among the CTs occurred. Either all three CTs rated the slide as positive (ASCUS+), two out of three
rated it positive, one out of three, or none of them.
