Test Utility

Extractable Nuclear Antigen (ENA) antibody screen, (EliA SymphonyS ) is intended for the in vitro, qualitative measurement of antinuclear IgG antibodies in human serum. EliA SymphonyS is based on recombinant U1RNP, RNP70(70kDa, A, C), SS-A/Ro (60 kDa, 52 kDa), SS-B/La, Centromere B, Scl-70, Jo-1 proteins and a synthetic SmD3 peptide as antigen and is useful as an aid in the clinical diagnosis of patients with systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), Sjögren’s syndrome, scleroderma and polymyositis/dermatomyositis, in conjunction with other laboratory and clinical findings.

Individual Test Information Including Methodology & Reference Ranges

Reflex to UTI Criteria

Specimen Collection and Preparation

  • Venipuncture, Gel barrier tube preferred. 

  • Plain red top also acceptable. 

  • 5.0mL blood minimum. 

  • Pour serum into plastic pour off tube, label with source of serum (gold top or red top).

Specimen Storage and Stability

  • Centrifuge and transport to laboratory at room temperature. 

  • Samples are stable for 1 week when stored at 2-8C. 


Note: samples are stored at 2-8C for 7 days before disposal

Specimen Rejection

  • Improper/incomplete labeling; 

  • improper sample type; 

  • Quantity insufficient (QNS); 

  • lipemic or hemolyzed samples cannot be used.

Reference Range

The assay provides a numerical ratio and interpretative comments based on the numerical ratio: 


 <0.7 ratio = Negative; 0.7-1.0 ratio = Equivocal; >1.0 ratio = Positive


Antibody prevalence in autoimmune patients varies widely depending on disease area.  The proportion of sera from normal population found positive for antibodies covered by this EliA Symphony test is below 1%.  Expected values may vary depending on the population tested.


It is recommended to repeat equivocal results, after 8-12 weeks.
