Specimen Required
Patient Preparation
  
Collect
Plain red.  
Specimen Preparation
Let stand on clot for two hours. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL) If ordered in conjunction with a Raji Cell Assay, transfer two 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.  
Remarks
  
Stability
After separation from cells: Ambient: 2 hours; Refrigerated: Unacceptable; Frozen: 2 weeks (avoid repeated freeze/thaw cycles)  
Reference Interval
Less than 4 µgE/mL is considered negative for circulating complement binding immune complexes.  
Interpretive Data
Circulating immune complexes may be found without any evident pathology and positive results do not necessarily implicate the immune complex in a disease process.
