Flow Cytometry - Clinical Significance:
Refer to:
- Reference Range:
- Raji 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.
- 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.
