[Test strips for rationalising microscopic tests of urinary sediment (author's transl)].

An attempt was made, by means of test strips for leucocytes, eruthrocytes, protein, ketone bodies, nitrate and ascorbic acid to distinguish urine samples with abnormal sediments. The urinary sediment was, at the same time, quantified with the Kova system. It was demonstrated that the teststrip system can separate out nearly all samples containing significant amounts of sediment. In addition, lysed erythrocytes and leucocytes are detected. It is, therefore, suggested to restrict microscopic examination to those samples which have been positive to at least one test strip. It is important that genital cleansing is undertaken before micturition.
