ABSTRACT:
An apparatus for the recovery of cell material from body fluids is described which consists of a filter with a filter material arranged in one or more layers and not soluble in cell-fixing liquids, such as isopropanol. The filter material consists of a single textured or crimped filament yarn. Preferably, the filaments of the filament yarn are made of synthetic polymers. In contrast to the known apparatus, consisting essentially of a filter cartridge which contains as filter material synthetic fibers dissolvable in alcohol or in an alcohol-water mixture, the use of the apparatus of this invention produces a cell sample which is not interspersed with particles of the filter material. Besides, the present invention permits to achieve very low cell losses, and cell damage does not occur. Body fluids from which cell material may be recovered with the apparatus according to this invention are for example, urine, liquor, pleural effusions or fluids from the abdomen area.
