[A problems in diagnosis of "leucocyturia". A simple method for a quantitative evaluation of urinary cell concentration (author's transl)].

The increased urinary excretion of white blood cells is usually associated with morphological features. The widely used urine sediment is not able to provide a proper diagnostic approach, but only some diagnostic aid concerning qualitative aspects (white blood cell casts). The ADDIS count is too elaborate for general practice and hospital management, even under simplified conditions. Neither have the visual field method using uncentrifuged urine and the counting of white blood cells in the counting chamber become routine diagnostic procedure. A new test strip for leucocytes is introduced. As a bedside test in hospital care and general practice it will be able to replace former methods regarding quantitative evaluation of leucocyturia.
