Table 2:

Tuberculosis infection test concordance and agreement among HIV-exposed infants who had both IGRA and TST at 44 weeks (n=710)

	TST positive	TST negative	Total
IGRA positive	8	34	42
IGRA negative	46	622	668
Total	54	656	710

IGRA positivity was defined as IFN-γ concentration ≥0·35 IU/mL. TST positivity was defined as induration diameter ≥5 mm for infants with HIV and ≥10 mm for infants without HIV infection. Negative IGRA included negative and indeterminate results; one infant who tested positive on IGRA did not have a TST. IGRA=interferon-γ release assay. TST=tuberculin skin test.
