Could a new skin test better detect TB in seniors?

NCT ID NCT05899179

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a new skin test called EC to see if it can accurately diagnose tuberculosis (TB) infection in adults aged 65 and older. Researchers compared EC with a standard TB skin test (TB-PPD) and a blood test (T-SPOT) in 780 participants, including TB patients and healthy volunteers. The goal was to see how well EC detects infection and whether it causes any side effects.
