This sounds like something that is done in every American hospital - the "automated diff." In a blood count, the cells are examined and determined to be red cells, white cells, or platelets. Within each category of cell there are sub-types (neutrophils, lymphocytes, monocytes, eosinophils, basophils) and sub-sub-types (bands, metamyelocytes, etc). Basically, you can automatically identify members of various cellular lineages. Cool that they got this to work through an iPhone camera.
