Abstract

The invention concerns a method of detecting proteins, especially HIV and CMV antibodies in body fluids using solid-phase immune reaction with a buffer containing an animal serum and/or a non-ionic surfactant in a phosphate or carbonate buffer together with further additives selected from inorganic salts, water-soluble polymers, organic compounds, and propionic acid and their derivatives and mixtures. The buffer makes it possible to reliably eliminate false positive results.
