Fluorescent dye-tagged rare cells are disposed in a biological fluid layer contained in an annular gap (12) between an inside test tube wall (14) and a float wall (16). One or more analysis images are acquired at one or more focus depths using a microscope system (10, 10', 10'', 10'''). Each acquired analysis image is image processed each to identify candidate rare cell images. The test tube (72) is selectively rotated. The test tube and the microscope system are selectively relatively translated along a test tube axis (75). The acquiring and image processing are repeated for a plurality of fields of view accessed by the selective rotating and selective relative translating and substantially spanning the annular gap.
