To examine urine for particulate constituents, the urine is pased through a filter of synthetic fibers that are soluble in alcohol or in an alcohol-water mixture immediately after withdrawal. The filter material together with the constituents retained in it is then immediately dissolved in a cell-fixing solvent, in which it is protected from environmental influences and stored until it is examined. An appropriate device for the implementation of this method consists of a urine collector and a filter cartridge which is fastened to the collector by a spring catch and can be detached after the urine has been passed through the filter, and connected liquid-tight with a storage vessel containing the solvent.
Method of examining urine for particulate constituents comprising:
Device for carrying out the method of examining urine for particulate constituents, the device consists essentially of (a) a urine collector, and (b) a detachable filter cartridge, which is affixed to said collector, said filter cartridge containing, as filter material, synthetic fibers that are soluble in alcohol or in aqueous alcohol, after the urine has passed through the filter, and after the collector has been removed, a liquid-tight connection is establishable between one opening of the filter cartridge and a storage vessel and the other opening is closable in a liquid-tight manner.
