ABSTRACT:
A virus infection examination apparatus includes a microscope for observing fluorescent images of antigen positive and negative cells dyed with a fluor by an indirect fluorescent antibody method using a serum of an object to be examined. An image pickup unit converts the fluorescent images as observation images of the microscope into image data. A detection unit processes the image data obtained by the image pickup unit and detects intracellular luminance distributions. A determination unit determines the presence/absence of a virus infection of the object on the basis of a difference between the fluorescent luminance distributions detected by the detecting unit.
