Blood test may reveal hidden inflammation in back pain patients
NCT ID NCT07509463
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 65 adults with ankylosing spondylitis, a type of arthritis that affects the spine. Researchers wanted to see if a blood test called the CALLY index could measure inflammation better than patient-reported symptoms. They reviewed medical records and compared the CALLY index to standard disease activity scores. The goal is to find a more objective way to track inflammation.
