  • Patients tested for both antigens (CFP-10 and ESAT-6) were analysed (n = 7). TST is expressed as positive with a threshold of 10 mm. Results of each test for each subject are reported as Pos (positive) or Neg (negative) (exact value). Results for ELISPOT are expressed as the number of IFNγ-producing cells/106 cells.
