Abstract
A method for immunoassay of an analyte in a fluid includes contacting the analyte with an antianalyte to give a bound fraction. The bound fraction activates the first component of complement whereby a substrate present in the fluid is modulated to provide a detectable signal. The signal may be detected to establish the presence or absence of the analyte in the fluid, or it may be quantitatively measured to determine the concentration of the analyte in the fluid. The invention includes a kit of materials useful in performing the method of the invention.
