The traditional method for measuring total complement activity in serum is the CH50 test, which is a measure of total complement activity. Total complement haemolytic activity was measured with assays specific for the classical (CH50-C) and alternative (CH50-A) pathway. One of the more common tests is known as a total hemolytic complement, or a CH50 measurement. Complement C4 is a protein that is important for your immune function. The Complement System1 1. The signal that initiates the domino cascade (called "activating" complement) is that an antibody meets an antigen (the bacterium or virus). CH50 is a screening test for total complement activity. The total complement (CH50) assay (COM / Complement, Total, Serum) assesses the classical complement pathway including early components that activate the pathway in response to immune complexes (C1q, C2 and C4), as well as the terminal complement components (C3, C5, C6, C7, C8, C9) involved in the formation of the membrane attack complex (MAC).
