Abstract
T-SPOT®.TB and the tuberculin skin test (TST) were used to screen for latent tuberculosis infection among 899 Chinese college students. The positivity rates for T-SPOT®.TB and TST were respectively 13.0% (95% confidence interval [CI] 10.4-15.9) and 24.9% (95%CI 21.5-28.6) among students with a bacille Calmette-Guérin (BCG) scar (agreement of both tests 72.3%; 95%CI 68.6-75.8; κ = 0.118), and respectively 17.3% (95%CI 11.7-24.2) and 23.7% (95%CI 17.3-31.2) among those without a BCG scar (agreement 73.1%; 95%CI 65.4-79.9; κ = 0.179). These results demonstrate low agreement between the TST and T-SPOT.TB in the Chinese population studied.
