Monthly Follow up of Interferon Gamma Releasing Assay (IGRA) Among Health-care Workers Treating Tuberculosis (TB) Patients

Interferon gamma releasing assay(IGRA) is useful to diagnose latent tuberculosis. However,IGRA responses could show within-subject variability. We wanted to determine long-term IGRA variability in health-care workers who continuously expose to tuberculosis patients.
