Among the 28 subjects analyzed, 18 with active TB and 10 without active TB, the median responses to selected ESAT-6 peptides (40 spot-forming cells [interquartile range {IQR}, 0–414 spot-forming cells] vs. 17 spot-forming cells [IQR, 0–298 spot-forming cells] p = 0.09) and selected CFP-10 peptides (83 spot-forming cells [IQR, 18–580 spot-forming cells] vs. 14 spot-forming cells [IQR, 0–288 spot-forming cells]; p = 0.1) were not significantly higher in the group with active TB, compared with the control group. Here, CFP is linked to tuberculosis.
