Setting: The infection with Mycobacterium tuberculosis gives a delayed immune response, measured by the tuberculine skin test. We present a new technique for evaluation based on automatic detection and measurement of skin temperature due to infrared emission. Design: 34 subjects (46.8 ± 16.9 years) (12/22, M/F) with suspected tuberculosis disease were examined with an IR thermal camera, 48. h after tuberculin skin injection. Results: In 20 subjects, IR analysis was positive for tuberculine test. Mean temperature of injection area was higher, around 1. °C, for the positive group (36.2 ± 1.1. °C positive group; 35.1 ± 1.6. °C negative group, p < 0.02 T test for unpaired groups). Conclusion: IR image analysis achieves similar estimation of tuberculin reaction as the visual evaluation, based on higher temperature due to increased heat radiation from the skin lesion. © 2015 Elsevier Ireland Ltd.

The infection with Mycobacterium tuberculosis gives a delayed immune response, measured by the tuberculine skin test. We present a new technique for evaluation based on automatic detection and measurement of skin temperature due to infrared emission.34 subjects (46.816.9 years) (12/22, M/F) with suspected tuberculosis disease were examined with an IR thermal camera, 48 h after tuberculin skin injection.In 20 subjects, IR analysis was positive for tuberculine test. Mean temperature of injection area was higher, around 1C, for the positive group (36.21.1C positive group; 35.11.6C negative group, p<0.02 T test for unpaired groups).IR image analysis achieves similar estimation of tuberculin reaction as the visual evaluation, based on higher temperature due to increased heat radiation from the skin lesion.
