This trial is testing a new skin test called C-TST (ESAT6/CFP10) to detect hidden tuberculosis infection in people with rheumatologic diseases who are about to start biologic or targeted synthetic medications. The study compares this new test with standard tests used today to see if it's better at finding tuberculosis infection early, before patients start treatment.
People taking biologic medications for rheumatologic diseases have a higher risk of developing active tuberculosis if they have a hidden infection. This trial is designed to find out if the new test can better detect hidden tuberculosis and help doctors prevent active disease in these patients.

You would have two skin tests done on your forearms (one new test and one standard test) and a blood test for tuberculosis. The skin tests would be read 48 to 72 hours later. If you are found to have hidden tuberculosis infection, you would receive treatment following current guidelines, and then be monitored regularly for 2 years to track your health and outcomes.
