WHAT IS RAJI CELL IMMUNE COMPLEX ASSAY TEST?
Complement receptors for IgG are found on the Raji cells, which are lymphoblastoid cells that contain receptors for the complement, particularly C3b. Raji cells are derived from Burkitt’s lymphoma and are used to recognize and bind protein-bound immune complexes that contain C3b. Results are reported as the quantity of precipitated immune complexes. Detection of circulating immune complexes is used to help determine the mechanisms of autoimmune diseases.
