[Evaluation of test strips for the semi-quantitative screening for proteinurias (author's transl)].

Commercial test strips using the protein error of certain indicators for the colorimetric detection of protein (especially albumin) were compared with a quantitative nephelometric method. The study proved that there is good agreement between the results from the quantitative method and those from the test strips (Rapignost Protein/Combur-8-Test). Both test strips generally shoed a good separation of the segments for semi-quantitative determinations. There was a very good agreement between the test strips in protein-containing urines. In protein-free urines, however, the Combur-8-Test showed a slightly higher proportion of false-positive results.
