Researchers are trying to find new biomarkers—measurable signs in your blood—that can help doctors diagnose three inflammatory rheumatic diseases (ankylosing spondylitis, rheumatoid arthritis, and systemic lupus erythematosus) much faster and more reliably. Currently, these diseases can take a long time to diagnose because doctors have to wait for certain blood tests and imaging changes to show up. This study analyzes blood samples from patients with these conditions and healthy people to develop a quick diagnostic test that could eventually be used in clinics.
Early diagnosis and quick treatment of these diseases leads to much better outcomes for patients. Right now, many people experience delays in diagnosis because the standard blood tests and imaging are negative early on. This research aims to identify new biological markers that appear earlier, so doctors can catch and treat these diseases sooner.

If you qualify, you will come in for a screening visit where doctors will review your medical history, do a physical exam, and take X-rays. You will then donate a blood sample, which researchers will analyze to look for new diagnostic markers. The study does not involve taking any new medications—it is purely observational, focusing on laboratory testing of your blood to help develop better diagnostic tools for future patients.
