1. A method for detecting an abnormal condition of cells included in a sample of cells, comprising: (a) comparing image data for a plurality of simultaneously collected images of individual known normal cells with image data for a plurality of simultaneously collected images of individual known abnormal cells to identify at least one characteristic that can be measured and which distinguishes a known abnormal cell from a known normal cell; (b) imaging the sample of cells to collect sample imaging data for a plurality of simultaneously collected images of individual cells in the sample cells, wherein the simultaneously collected images for the known normal cells, the known abnormal cells, and the sample cells each include at least one of the following two types of images: (i) multispectral images; and (ii) multimodal images; and (c) analyzing the sample image data to determine if any cells in the sample of cells exhibit the abnormal condition, by detecting the at least one cell characteristic that distinguishes the known abnormal cells from the known normal cells.
