Raji Cell Immune Complex Assay : 0050302

Mnemonic: RAJI

Methodology: Flow Cytometry
Performed: Tue
Reported: 2-9 days
Specimen Required: Collect: One 7 mL plain red or serum separator tube.

Storage/Transport Temperature: 3 mL serum, frozen. (Min: 0.5 mL)

Remarks: CRITICAL FROZEN. SEPARATE SPECIMENS MUST BE SUBMITTED WHEN MULTIPLE TESTS ARE ORDERED. Let stand for two hours, then separate serum from cells within one hour and freeze immediately.

Unacceptable Conditions: Nonfrozen specimens. Specimens exposed to repeated freeze/thaw cycles.

Stability (collection to initiation of testing): Ambient: Unacceptable; Refrigerated: Unacceptable; Frozen: 30 days
Reference Interval:
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.

Please refer to Statement A in the Compliance Statements section in the front of the Laboratory Test Directory.
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.
CPT Code(s): 86332
Cross References: Immune Complex Assay (Raji Cell)
