Primary Institution: Innsbruck Medical University
Hypothesis
The new automated method for determining anti-CCP2 will provide comparable results to existing ELISA methods.
Conclusion
The new automated assay for anti-CCP2 demonstrated a diagnostic sensitivity of 80% and specificity of 97%, comparable to existing methods.
Supporting Evidence
- The new automated assay showed a diagnostic sensitivity of 80% and specificity of 97%.
- Results from the automated method were comparable to those from the existing ELISA tests.
- Anti-CCP testing has increasing acceptance in laboratory medicine.
Takeaway
Doctors tested a new machine that checks for a specific antibody in blood to help diagnose rheumatoid arthritis, and it worked just as well as the old tests.
Methodology
Five hundred and forty-three serum samples were tested for anti-CCP2 using both a commercially available ELISA and a new automated method.
Limitations
The study did not address the long-term reliability of the automated method or its performance in diverse populations.
Participant Demographics
395 female and 148 male outpatients from a hospital with joint problems.
