Sensitivity and Synergism of Tuberculin Skin Test (TST), Smear microscopy and GeneXpert in Diagnosis of Overt and Latent TB Infection in Mixed Population

The study consisted of a cross sectional
examination of infection profile focusing more on
screening overt and asymptomatic (latent) TB infections
in Correctional facilities (CF) in Cross River State. All
tuberculosis cases (overt and latent) were screened using
Tuberculin Skin Test, Smear microscopy and GeneXpert
(GXPT) respectively. Inmates’ positive for TST, AFB and

GXPT were also screened for Human Immuno-
deficiency virus (HIV) antibodies.
