Turbidimetric Method

These kits are designed for the quantitative determination of specific proteins in a solution. The assay principle is based on the formation of antigen-antibody complexes that scatters light on its path, and the decreased transmission of light is correlated to the increased antigen concentrations. Anti-human IgA, IgG or IgM antibodies form insoluble complexes when mixed with samples containing IgA, IgG or IgM. The scattering light of the immunocomplexes depends of the IgA, IgG or IgM concentration in the patient  sample, and can be quantified by comparison from a calibrator of known IgA, IgG or IgM concentration
