EliA Autoimmunity

Test results with high clinical value are the basis of clinical decisions and the key for diagnostic success.

EliA assays combine exceptional specificity with highest sensitivity and provide the guidance and safety clinicians need for their daily diagnostic decisions. Most important, the positive predictive values and likelihood ratios of our EliA assays give excellent values assuring high clinical usefulness in routine practice.

For many tests quantitative results enable estimations on the severity and the prognosis of the disease. Quantitative results therefore have a higher clinical value than qualitative results which solely point out if the test result is ‘positive’ or ‘negative’.

“Phadia EliA dsDNA assay provides the best specificity, positive predictive value and post-test probability in the study.”

“Importantly, positive predictive values of the automated tests (85.2%) in comparison to the CCP IgG 3.0 manual ELISA (72.5%) resulted in a better correlation with clinical RA.”
Elfrefaei, J.Clin. Immunol. 2011

"EliA dsDNA detects anti-dsDNA antibodies in patients with renal involvement more frequently and with a significantly higher mean titer compared to patients without this complication."
