Keywords

IGRA, variability, Long-term variability of IGRA

Brief summary

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.

Detailed description

IGRA will be performed monthly in health-care workers with continuous exposure to tuberculosis patients for 1 year.

Interventions

OTHERBlood samplings

About 3.5ml of blood will be drawn from the participants monthly.
