Table 3. Responder frequenciesa in different TB related tests in the blind study.
| Patient group | TST≥5 mm | tuberculin in vitrob ICS vs. supernatant | ESAT-6 in vitroc ICS vs. supernatant |
| smear and/or culture positive TB (n = 12) | 5/7 | 12/12 vs. 12/12 | 5/11 vs. 5/11 |
| smear and culture negative TB (n = 10) | 6/9 | 7/10 vs. 5/10 | 1/10 vs. 1/10 |
| ≥1 year after beginning of TB treatment (n = 8) | 5/7 | 9/9 vs. 8/8 | 4/9 vs. 4/8 |
| Control patients (n = 17) | 0/12 | 10/17 vs. 9/17 | 3/16 vs. 3/15 |
a
not all test were performed in all individuals, numbers refer to positive test results per tested individuals
b
frequency of tuberculin-reactive CD4 T-cells (IFN-gamma) above 1/10,000 or IFN-gamma above 0.1 IU/ml (arbitrary value)
c
frequency of ESAT-6 reactive CD4 T-cells (IFN-gamma) above 1/10,000 or IFN-gamma above 0.1 IU/ml (arbitrary value)
