Designed to offer your laboratory high performance and reliable results. Based on advanced techniques such as recombinant antigen technology, EliA™ assays are standardized, precise, reliable and easy-to-use. We currently offer autoantibody tests for more than 20 clinical indications in the fully automated EliA system.


One unique aspect of EliA is the ability to utilize one master isotype curve for each group of assays. All assays that are IgG in nature run from one IgG master curve. The same is true for IgM and IgA–each using a single IgM or IgA master calibration curve. This technology optimizes workflow by eliminating the need to run calibration curves for individual assays. In this case, less is truly more. The benefit of this technology for your laboratory is the ability to optimize workflow by eliminating the need to run calibration curves for every single analyte.

Why specificity matters in autoimmune disease diagnosis

When your laboratory provides highly specific tests, such as the EliA assays, the results matter to clinicians because of their higher positive predictive value, leading to a greater confidence in diagnosis.

EliA assays pioneered the use of recombinant sources, respectively expressed in baculovirus insect cells, in order to secure reproducible and high-quality antigens. This recombinant expression allows the production of large, reproducible batches of purified proteins that overcome the quantity limitations associated with human raw material. As a result, EliA assays are associated with less contamination and fewer false positives.

EliA autoimmunity assays

Combining exceptional specificity and sensitivity to aid in autoimmune disease diagnosis. EliA assays, which run on most Phadia™ Laboratory Systems, can help your laboratory aid in the diagnosis of autoimmune diseases including:

  • Antiphospholipid Syndrome
  • Connective Tissue Diseases
  • Gastrointestinal Diseases
  • Celiac Disease
  • Liver Disease
  • Rheumatoid Arthritis
  • Thyroid Diseases
  • Vasculitis

And if your laboratory is already running ImmunoCAP™ Specific IgE blood tests, adding EliA assays is easy.
