A method includes carrying out at least a first processing of a sample (2), the processing being adapted to mark pathological cells among the sample cells; and carrying out several image acquisitions of the sample (2) provided on an analysis plate (6) in order to obtain images each representing an area of the analysis plate (6) wherein the images set side by side define an image (20) of the entire sample. The method further includes automatically running all the acquired images of the sample (2) on a display at a predetermined running speed, the speed being adapted for enabling an observer to analyze the image and to determine if the represented sample area includes potentially pathological cells or not; and stopping the running if at least one abnormality is detected that may indicate the presence of a pathological cell.
