Methodology: Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Performed: Mon
Reported: 1-8 days
Specimen Required: Collect: Serum separator tube.

Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.2 mL)

Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year

Interpretive Data:  Elevated RNA polymerase III IgG antibodies are found primarily in a subset of systemic sclerosis (SSc) patients who are typically negative for anti-centromere and anti-Scl-70 antibodies, and which may be predictive of increased risk for skin involvement and hypertensive renal failure associated with the diffuse cutaneous form of scleroderma.
