Table 1 Demonstration of Ag 85 complex in sera from tuberculosis and non-tuberculosis patients by indirect ELISA method using the mAb against purified Ag 85 complex along with mean absorbance (with range)

From: Diagnosis of tuberculosis in an Indian population by an indirect ELISA protocol based on detection of Antigen 85 complex: a prospective cohort study

Patient group Positivity for Ag 85 complex (cutoff of 0.18) Negativity for Ag 85 complex Absorbance (Mean ± 2SD) Range
Tuberculosis group (n = 128) 105 (82.03%) 23 (17.96%) 0.42 ± 0.22 0.03 – 0.92
Confirmed (n = 24) (AFB & ulture positive) 23 (95.83%) 1 (4.17%) 0.64 ± 0.22 0.22 – 0.92
Clinically diagnosed (n = 104) (AFB & ulture negative) 82 (78.84%) 22 (21.16%) 0.37 ± 0.19 0.03 – 0.92
Non-tuberculosis group (69) 10(14. 49%) 59 (85. 51%) 0.16 ± 0.08 0.01 – 0.36
Disease Control(n = 49) 10 (20.40%) 39 (79.59%) 0.17 ± 0.09 0.01 – 0.36
Healthy Control(n = 20) 0 (0%) 20 (100%) 0.13 ± 0.05 0.02 – 0.21
