Immune complexes formed in solution scatter light in proportion to their size, shape and concentration. Turbidimeters measure the reduction of incidence light due to reflection, absorption or scatter. The decrease in light intensity transmitted through particles suspended in solution is a result of complexes formed during the immunological reaction between the RF of the patient serum and the anti-RF IgG antibodies coated on the latex particles.
