0050302Raji Cell Immune Complex Assay By report
Interpretive Data
Many autoimmune disorders, chronic infections and malignancies are associated with circulating immune complexes. Quantitation of immune complexes assists in staging immunologic disorders.

See Compliance Statement A: www.aruplab.com/CS
Note
Immune complexes bind to Raji Cells via their complement receptors. The immunoglobulin portion of the immune complex is then detected by flow cytometry with anti-human IgG-FITC.
