|Methodology:||Nephelometry (NEPH) / Multiple Flow Immunoassay (Luminex)|
|Components:||Antinuclear Antibodies (ANA) / Complement C3 / Complement C4 / Double Stranded DNA Antibody (dsDNA) / Extractable Nuclear Antigen (ENA) Antibodies, Sm & RNP / Extractable Nuclear Antigen (ENA) Antibodies, SS-A/Ro & SS-B/La|
|Released:||Same day as tested|
|CPT Code:||86038 / 86160 x2 / 86225 / 86235 x4|
|Specimen Collection Details|
|Collection:||Two 7.5 mL serum separator tubes (SST). Also acceptable: Two 5 mL red top tubes.|
|Handling:||Allow to clot for 30-60 minutes at 20-25° C. Do not clot at 2-8° C. Centrifuge and within 1 hour separate serum from cells into two plastic vials.
For C3/C4 testing: Freeze one tube ≤ -20° C. Allow no more than one freeze/thaw cycle.
For ANA testing: Refrigerate second tube at 2-8° C. Freeze ≤ -20° C if specimen cannot be tested within 7 days. Allow no more than three freeze/thaw cycles.
|Stability:||C3/C4 testing:1 year frozen ≤ -20° C.
ANA testing: 7 days refrigerated at 2-8° C.
|Standard Volume:||1 mL serum for ANA testing and 1 mL serum for C3/C4 testing.|
|Minimum Volume:||0.5 mL serum for C3/C4 testing and 0.5 mL serum for ANA testing.|
|Transport:||Frozen on dry ice for C3/C4; refrigerated or frozen on dry ice for ANA testing.|
|Rejection Criteria:||C3/C4 Testing: Plasma, grossly lipemic, hemolytic, or contaminated specimen; specimen allowed to clot at 2-8° C; specimen frozen/thawed more than once.
ANA Testing: Plasma; grossly lipemic, hemolytic, or contaminated specimen; refrigerated specimen received in laboratory more than 7 days after collection; specimen frozen/thawed more than 3 times.
