C1 esterase inhibitor complement antigen (C1ES) is measured by immunonephelometry. Antiserum to C1ES is mixed with patient serum, the light scatter resulting from the antibody interaction with C1ES is measured, and the signal is compared to standard concentrations of C1ES.(Instruction Manual: Siemens Nephelometer II Operations, 2005)
