New TB skin test could spare rheumatoid patients from hidden infection
NCT ID NCT06796647
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests a new skin test (C-TST) to find hidden tuberculosis (TB) infection in people with rheumatic diseases like rheumatoid arthritis who are about to start powerful medications called biologics. These drugs can reactivate dormant TB, so accurate screening is critical. Researchers will compare the new test with standard skin and blood tests in 100 adults, then follow them for two years to see who develops active TB.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ESAT6/CFP10 skin test (C-TST)
What this could lead to
If successful, this could provide a more accurate and convenient way to detect hidden TB infection in people with rheumatic diseases, helping prevent active TB when they start certain medications.
What could go wrong
This is a small, early-stage study with only 100 participants. The new test may not prove more accurate than existing methods, and results may not apply to all patient groups.
