Background: Two commercial blood assays for the diagnosis of latent tuberculosis infection-T-SPOT.TB and QuantiFERON-TB Gold-have been separately compared with the tuberculin skin test.

Findings: Overall agreement with the skin test was similar (T-SPOT.TB κ=0·508, QuantiFERON-TB Gold κ=0·460), but fewer BCG-vaccinated individuals were identified as positive by the two blood assays than by the tuberculin skin test (p=0·003 for T-SPOT.TB and p
