Specimen Required
Patient PreparationInstructions patient must follow before/during specimen collection.
CollectSpecimen type to collect. May include collection media, tubes, kits, etc.
Plain red or serum separator tube (SST)
Specimen PreparationInstructions for specimen prep before/after collection and prior to transport.
Allow complete clotting of red blood cells (up to 1 hour), then separate serum from cells within 30 minutes and freeze immediately. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL) If ordered in conjunction with a Circulating Immune Complex, C3 fragments, transfer TWO (2) 1 mL aliquots of serum to individual ARUP Standard Transport Tubes.
Storage/Transport TemperaturePreferred temperatures for storage prior to and during shipping to ARUP. See Stability for additional info.
CRITICAL FROZEN.Separate specimens must be submitted when multiple tests are ordered.
Unacceptable ConditionsCommon conditions under which a specimen will be rejected.
Non-frozen specimens.
RemarksAdditional specimen collection, transport, or test submission information.
StabilityAcceptable times/temperatures for specimens. Times include storage and transport time to ARUP.
After separation from cells: Ambient: 2 hours; Refrigerated: Unacceptable; Frozen: 2 weeks (avoid repeated freeze/thaw cycles)
Expected turnaround time for a result, beginning when ARUP has received the specimen.
2-9 days
Reference Interval
Normal range/expected value(s) for a specific disease state. May also include abnormal ranges.
Effective February 19, 2019 Less than or equal to 3.9 µg Eq/mL
Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
Less than or equal to 3.9 µg Eq/mL is considered negative for circulating complement binding immune complexes. Circulating immune complexes may be found without any evident pathology and positive results do not necessarily implicate the immune complex in a disease process.
