[Heterogeneity of therapeutically-used human albumin preparations].

29 human albumin solutions commercially available in Germany were analyzed. Results for total protein vary between 86,25% and 102.40% of the declared value. Values for monomer albumin are between 74.19% and 91.81% of the declared value for total protein (test method: discontinuous polyacrylamide gel electrophoresis). With an sodium content, there are also various differences in quality in missing or wrong declarations of the electrolytes.
