Abstract: A slide number estimation apparatus (2000) acquires a slide image (30). The slide image (30) an image of a specimen slide (20) obtained from a tissue piece (10) of a subject. The slide number estimation apparatus (2000) estimates the number of tumor cells included in a region of interest (22) of the specimen slide (20) corresponding to the obtained slide image (30) using the slide image (30). The slide number estimation apparatus (2000) estimates the number of the specimen slides (20) to be obtained from the tissue piece (10) for conducting a predetermined test based on the estimated number of tumor cells.

Abstract: The present invention assists with genetic testing in which pathological image data is used. A classifying unit (11) uses pathological image data, which is the test subject of genetic testing, to classify the test object by tumor cell type. A selecting unit (13) selects, from among available pathologists who can be asked to assist, a pathologist candidate to be asked to assist with the genetic testing, on the basis of the tumor cell type. A presenting unit (14) displays the pathologist candidate.

Abstract: Provided is a technique that suggests a testing region suited to dissection in genetic testing of somatic cells. An acquisition unit (11) acquires image data of a pathological specimen; an estimation unit (12) estimates the content ratio of tumor cells in each of individual regions in a focus region in the image data of the pathological specimen; a determination unit (13) determines a testing region in the focus region on the basis of the content ratio of tumor cells in each of the individual regions in the focus region; and an output unit (14) outputs information indicating the testing region.
