The invention relates to the field of detecting and optionally collecting and isolating rare event particles. The method according to the invention is based on relatively simple optical equipment, which requires a few and uncomplicated decisions for the user of the system. The method is based on the acquisition of an image of relatively low resolution and magnification of a large volume of sample and detecting the presence or absence of the rare event particle. The method is then repeated with at least one further volume of sample. The method is particularly adapted for detection of white blood cells in leuko-depleted blood.
