[Latex immunologic methods of determining micro-molecular proteins and albumins in urine. Part I. Description of the method].

The most frequent markers of early kidney dysfunction include determination of micromolecular proteins, such as beta 2-microglobulin (beta 2M), retinol-binding protein (RBP) and albumins (Alb), in urine. The determination of those proteins in urine is carried out by means of immunological methods. The latex-immunological methods (LIA), allowing to avoid the use of radioisotopes and relatively cheap one as compared with ready-made proprietary kits, may prove to be particularly useful in Polish laboratories. The LIA method in routine tests of protein content in urine was practically assessed. Reproducibility of the method was verified under the conditions of international quality control.
