This test is New York DOH approved.
Specimen Required
Patient Preparation
Collect
Plain red or serum separator tube (SST).
Specimen Preparation
Allow complete clotting of red blood cells (up to 1 hour), then separate serum from cells within 30 minutes and freeze immediately. Transport 1 mL serum. (Min: 0.5 mL) If ordered in conjunction with a C1q Binding Assay, transfer TWO (2) 1 mL aliquots of serum to individual ARUP Standard Transport Tubes.
Storage/Transport Temperature
CRITICAL FROZEN. Separate specimens must be submitted when multiple tests are ordered.
Unacceptable Conditions
Non-frozen specimens. Specimens exposed to repeated freeze/thaw cycles.
Remarks
Stability
Ambient: Unacceptable; Refrigerated: Unacceptable; Frozen: 30 days
Reference IntervalNormal range/expected value(s) for a specific disease state. May also include abnormal ranges.
By report
Interpretive DataBackground information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
Many autoimmune disorders, chronic infections and malignancies are associated with circulating immune complexes. Quantitation of immune complexes assists in staging immunologic disorders.
Compliance Category
Laboratory Developed Test (LDT)
NoteAdditional information related to the test.
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.
